Medicina - Epidemiologija / Medicine - Epidemiology

Pneumonije povezane sa mehaničkom ventilacijom predstavljaju jednu od najčešćih formi intrahospitalnih infekcija u jedinicama intenzivnog lečenja. Ciljevi ove disertacije su bili da se sagledaju faktori rizika vezani za karakteristike pacijenta kao i za karakteristike i stanje na prijemu koji su od značaja za pojavu pneumonija povezanih sa mehaničkom ventilacijom. Takođe je cilj bio da se sagleda incidencija multirezistentnih sojeva patogena u bolničkim uslovima kao i efikasnost empirijske antibiotske terapije. Praćeno je 363 pacijenata koji su lečeni u Urgentnom centru Kliničkog Centra Srbije, u dve jedinice intenzivnog lečenja i koji su zahtevali mehaničku ventilaciju duže od 48 sati u periodu od 1.1.2013. do 31.12.2014. godine. Ispitivan je uticaj demografskih karakteristika, uzroka hospitalizacije i pratećih bolesti, kao i karakteristika pacijenata na prijemu u jedinice intenzivnog lečenja. Nezavisni prediktori za nastanak pneumonija povezanih sa mehaničkom ventilacijm prema multivarijantnoj regresionoj analizi su: primena masivne transfuzije na prijemu, koma, GKS manjeg od 8 i veći APACHE II skor. Pacijenti koji su razvili pneumoniju duže su boravili na mehaničkoj ventilaciji i imali su duži boravak u jedinicama intenzivnog lečenja. Intrahospitalni mortalitet je bio u ovoj grupi značajno veći kao i mortalitet 28 dana. U multivarijantnoj logističko regresionoj analizi faktor rizika za nastanak prošireno rezistentnih bakterija kao uzročnika VAP-a izdvaja se neadekvatna empirijska antibiotska terapija. Gram negativne bakterije bili su najčešće izolovani patogeni. Na osnovu rezultata ove disertacije predlaže se uvođenje protokola i mera kojima bi se delovalo na preventibilne faktore rizika radi redukcije incidencije pneumonija povezanih sa mehaničkom ventilacijom sa ciljem sprečavanja komplikacija i samanjenje mortaliteta kod traumatizovanih pacijenata u jedinicama intenzivnog lečenja.

▼ The present work consists of two parts: experimental study of natural ventilation in a model room and the flow associated with a source-sink pair. The first part describes the natural ventilation of a model room of size 300mmx 300mm x 300mm with water as the fluid medium. It is insulated by air gaps on the four sides and at the top. A constant heat flux of 3148W/m2 has been maintained on the bottom surface of the room. This ‘room’ is surrounded by a large exterior tank containing water. The changes in temperature of the bottom, the interior and the exterior have been measured using T-type thermocouples. There are three openings each on two opposing sides of the model room. For any experiment, only one opening on each side is kept open. Fluid enters or leaves these openings and the flow is driven entirely by buoyancy forces. Three configurations have been studied: (1) The bottom opening at the inlet side and the top opening at the outlet side are open, (2) the bottom opening at the inlet side and the middle opening at the outlet side are open, and (3) the middle opening at the inlet side and the top opening at the outlet side are open. Shadowgraph technique is used for visualization. The buoyancy causes flow to enter through the bottom opening and leave through the top opening. At the openings, buoyant jets are observed and which have higher or lower relative densities. The buoyant jet at the inlet interacts with the plumes on the heated bottom plate. From these visualizations, it appears that free convection at bottom plate will be affected by the buoyant jets at the openings and the degree to which it is affected depends on the position and size of openings and distance between inlet and outlet. The flow rate due to the natural ventilation depends on the bottom surface heat flux and the height difference between the openings. The temperatures of the ﬂoor, the interior and the exterior are calculated using a simple mathematical model (Hunt and Linden [1999]). The mathematical model assumes well mixed conditions within the room and accounts for losses at the openings. The values of temperatures obtained in the experiments are reasonably well predicted by the mathematical model. The second part of the work is concerned with the interaction of a source -sink pair. The source consists of fluid issuing out of a nozzle in the form of a jet and the sink is a pipe that is kept some distance from the source pipe. Such source -sink pairs are observed in many situations including data centers, and collection of fresh water from a large reservoir that has also a discharge of pollutants. The main parameters of the problem are source and sink flow rates, the axial and lateral separations of the source and sink, and the angle between the axes of source and sink. Of concern is the percentage of source ﬂuid that enters the sink as a function of these parameters. The experiments have been carried in a large glass water tank. The source nozzle diameter is 6mm and the sink pipe diameter is either 10mm or 20mm. The horizontal and… Advisors/Committee Members: Arakeri, Jaywant H, Sreenivas, K R.

▼ Patients with trauma often require mechanical ventilation for prolonged periods because of their inability to protect their airways, persistence of excessive secretions and inadequacy of spontaneous ventilation. Tracheostomy is often performed in patients with prolonged translaryngeal intubation on ventilatory support. Its role in weaning from mechanical ventilation remains however subject to practice variation. This was a prospective study at Kenyatta National Hospital Intensive Care Unit (ICU) of patients admitted with trauma to determine the prevalence, timing and outcomes of patients done tracheostomy. Glasgow coma score (GCS) was used to assess severity of illness. All trauma patients 13 years and above with GCS of 8 and below and mechanically ventilated were followed until successfully weaned off the ventilatory support. For patients on whom tracheostomy was performed, the timing of the tracheostomy was noted. Tracheostomy was considered early if it was done before 14 days and late if it was done after 14 days on the ventilatory support. The technique of tracheostomy was also noted. Analysis was made to compare patients who had tracheostomy and those who did not have tracheostomy to establish if tracheostomy accelerates the weaning process in patients with anticipated prolonged ventilatory' support. Further analysis was also made to compare early and late Tracheostomy to 8 establish if early tracheostomy is associated with faster rate of weaning compared to late tracheostomy. This study was conducted for a period of six months starting from November 1st 2005 to April 30th 2006. Of a total of 108 trauma patients admitted to the ICU, initiated on mechanical ventilation and recruited into the study, tracheostomy was performed on 28 patients (17%). Comparing patients done to those not done tracheostomy, p value<0.005, patients done tracheostomy were found to have been weaned faster off mechanical ventilation. Comparing early (1-14 days) tracheostomy to late (>14 days), early was associated with shorter duration of mechanical ventilation, p-value <0.015.

Research Doctorate - Doctor of Philosophy (PhD)

Mechanical Ventilation is arguably one of the most common practices in Intensive Care Units and one of the main reason patients need admission to Intensive Care. The research in this thesis focuses on the provision of structured continuing education on mechanical ventilation undertaken in the clinical workplace as a component of nurses’ continuing professional development. A systematic review of the literature was conducted to determine whether the implementation of continuing education on mechanical ventilation for intensive care nurses results in the transfer of learning beyond the individual level and towards better patient outcomes. The aim of the review was to appraise and establish the best available evidence on the effectiveness of education programs that resulted in the improvement of patient outcomes. The next step taken in the research was the investigation of : (1) the role that intensive care unit nurses play in managing ventilated patients; (2) the knowledge registered nurses have about mechanical ventilation after finishing the undergraduate course in Australia; (3) and the quality of continuing education on mechanical ventilation at a post-registration level concerning building on, and maintaining nurses’ knowledge and skills looking after ventilated patients, and potentially influencing patient outcomes. This thesis reports the results of a sequential, two phase mixed methods study, which includes a cross-sectional study (Phase One), followed by individual interviews and focus groups (Phase Two). The research aims are to describe the provision of the continuing education program on mechanical ventilation provided at a major tertiary referral hospital, to explore the intensive care unit nurses’ perceptions of this education, their views of their scope of practice, to identify the barriers and motivators to participating in continuing education, and to investigate the nurses’ recommendations for improvement or change in the program. The research setting during Phase One and Two was a 22 bed intensive care unit of a large, regional tertiary referral hospital in Australia, which employed approximately 160 registered nurses. For Phase One applied in 2011, all nurses from the study intensive care unit were sampled for the survey and asked about their perception of the continuing education on invasive mechanical ventilation with focus on two main components: a <i>Self-directed learning package (SDLP) titled Adult ventilation management and the Recognition in Prior Professional Learning, Experiences, and Skills program (RIPPLES) – titled Care of a ventilated patient in intensive care</i>. The results of Phase One were used to inform Phase Two which was undertaken in 2015 where all nurse managers and nurse educators were sampled for individual interviews and three focus groups with purposively selected samples of expert, experienced and novice intensive care unit nurses were undertaken. The interviews and focus groups explored in-depth the managers’…

Research Doctorate - Doctor of Philosophy (PhD)

Daily sedation interruption (DSI) has been associated with improved physical outcomes such as short ventilator, intensive care unit (ICU) stay and increased number of survivors. To date, only one cohort study has investigated the long-term effects of DSI on critical illness and ICU survivors. However, numerous studies have argued that many survivors continue to suffer from the effects of their critical illness and the ICU treatment. There are no qualitative studies that have examined the experience of critical illness in ICU and beyond in the context of DSI and the meaning the patients attach to their experience. The purpose of this study was to describe the lived experience of people who experienced critical illness in ICU and following discharge. The research question for the study asked: What is the experience of critical illness in ICU and how does it affect people’s lives after discharge? Phenomenology was used as the methodological approach to this study. Participants aged between 20 and 76 years with an ICU stay ranging from 3 to 36 days were recruited from a 16 bed ICU in a large regional referral hospital in NSW, Australia. Participants were intubated and mechanically ventilated with DSI during their critical illness in ICU. In-depth face to face interviews with twelve participants were conducted at two weeks after discharge from ICU. A second interview was conducted with eight participants six to eleven months following the first interview. Interviews were audio taped and transcribed. Thematic analysis was conducted using van Manen’s six dynamic interplay activities. The main theme to emerge from the study was ‘being in limbo’. ‘Being disrupted’; ‘being imprisoned’ and ‘being trapped’ comprise the main subthemes of the study. The findings of this study have the potential to increase understanding of the experiences of people during and following critical illness by nurses and other health care professionals. The experiences of the participants in this study suggest the use of DSI, considered an innovation in the treatment of critically ill patients with improved physiological outcomes, may not improve lived experiences of critical illness in ICU and beyond. Recommendations are made for new models of care and support to mitigate the patients’ experiences.

▼ Mechanical ventilation (MV) is an unavoidable consequence in a variety of respiratory diseases. Mechanical strain associated with ventilation contributes to inflammation and ventilator-induced lung injury. Implicated in this injury are inflammatory mediators and reactive oxygen species (ROS) signaling. We utilized a variety of treatments and genetic ablations to understand specific oxidant and inflammatory signaling pathways and the interrelation of these pathways in a mouse model of MV. NADPH oxidase -/-, dexamethasone (dex) treated, TNFR-/-, IL-1β-/- and neutrophil (PMN)-depleted mice were used to investigate MV-induced oxidant and inflammatory responses. Mice were ventilated with a 10cc/kg tidal volume for 0-6 hours, depending on treatment group. Analysis included pulmonary function testing, histological analysis and pro-inflammatory cytokine measurements. Immunohistochemistry for ROS/Reactive Nitrogen Species stress response markers, antioxidant capacity, macrophages, PMNs, and markers of PMN activation were performed. Mechanically ventilated mice displayed changes in lung function, oxidant state, and an inflammatory response characterized by early recruitment of activated PMNs and increased pro-inflammatory cytokines with no discernable change in lung morphology. Decreasing ROS production led to changes similar to wild type (WT) mice in lung function and morphology while altering the oxidant response. NADPH oxidase -/- mice displayed an increased inflammatory response with MV similar to WT but with alterations in PMN activation. Altering inflammatory signaling minimally influenced the oxidant response while changing the inflammatory response. Ventilated dex-treated mice demonstrated significant PMN influx with an altered level of activity and attenuated pro-inflammatory cytokine production. TNFR-/- and IL-1β-/- mice showed a MV-induced PMN influx with an altered level of activity and a pro-inflammatory cytokine response similar to WT. PMN-depleted mice demonstrated an attenuated pro-inflammatory cytokine response to ventilation. These results demonstrate that ventilation alone using these parameters changes lung function and increases the inflammatory response with less effect on oxidant responses within the lung. While ROS signaling appears to play some role in PMN activation, inflammatory mediator signaling seems to play a more important role in PMN activation and pro-inflammatory cytokine production. PMN depletion confirmed that PMNs are necessary for both the oxidant and inflammatory changes associated with MV.

Des asynchronies patient-ventilateur sont fréquemment observées en ventilation assistée. Objectif : Déterminer l'incidence et les facteurs favorisants des asynchronies, venant du patient, du ventilateur ou des réglages, et préciser le réglage optimal du ventilateur. Méthodes : Nous avons évalué l'incidence des asynchronies avec une méthode simple et non invasive basée sur l'analyse des courbes du ventilateur. Chez les patients qui présentaient des efforts inefficaces, nous avons mesuré l'effort inspiratoire avec une sonde œsophagienne afin d'optimiser le réglage du ventilateur. Nous avons évalué l'impact du mode ventilatoire sur la qualité du sommeil avec une polysomnographie complète. Enfin, tous les ventilateurs de réanimation ont été testés sur banc afin de comparer les performances en termes de trigger et pressurisation. Résultats : Près d'un quart des patients présentaient des asynchronies fréquentes. La durée de ventilation de ces patients était plus longue et le sevrage plus difficile. Les efforts inefficaces, qui représentaient les asynchronies les plus fréquentes, étaient favorisés par une assistance ventilatoire excessive. La réduction du niveau d'aide inspiratoire (AI) permettait d'éliminer quasi-complètement les efforts inefficaces, sans augmenter l'effort inspiratoire et sans modifier la vraie fréquence respiratoire du patient. Le mode ventilatoire n'avait pas d'influence sur la qualité du sommeil et les asynchronies. Les efforts inefficaces survenaient aussi bien en AI qu'en ventilation assistée contrôlée. Avec un niveau d'AI adéquat, les apnées centrales étaient peu nombreuses et n'avaient pas d'influence sur la qualité du sommeil. Les performances insuffisantes observées avec certains ventilateurs peuvent également altérer la synchronisation. Conclusion : Les asynchronies patient-ventilateur sont fréquentes et associées à une durée de ventilation prolongée. Une « dose de ventilation » excessive favorise les efforts inefficaces, mais un réglage optimal du ventilateur permet de minimiser ces asynchronies. Cette thèse est un support pour déterminer dans une étude plus large si une synchronisation adéquate peut réduire la durée de ventilation.

Major patient-ventilator asynchrony seems common on ventilator screen during assisted mechanical ventilation. Objectives: To evaluate the incidence of major asynchrony and to identify factors related to patient's characteristics and ventilator parameters associated with asynchrony, and to determine optimal ventilator adjustments. Methods: We evaluated the incidence of major patterns of asynchrony easily detected using a noninvasive method based on flow and airway pressure curves. In patients with frequent ineffective efforts we measured patient's effort using esophageal pressure measurements to optimize ventilatory settings. We evaluated the impact of ventilatory mode on sleep quality using a complete polysomnography. All intensive-care-unit ventilators were compared on a bench test in terms of trigger performance and pressurization capacity. Results: One-fourth…

▼ The reality of the effect of natural ventilation in a residential attic cavity has been the topic of many debates and scholarly reports since the 1930’s. The purpose of ventilating an attic cavity is to prevent collection of condensate on the structural surfaces, and to create a thermal buffer between the conditioned space and the ambient air. The current standards are not specific to climate zone, despite the fact that each climate zone may require ventilation for very different reasons. To address the issue of ventilation effects in a hot and humid climate, a Natural Exposure Testing facility was constructed in Charleston, South Carolina in 2008. This multi-cavity in-situ facility is equipped with seven separate attic bays, featuring a wide variety of construction materials for performance comparison. Yearly performance comparison data has been examined for key observations on the effect of ventilation, which comprises approximately half of this report. Furthermore, an industry-standard attic performance prediction tool was benchmarked to the field data and is shown to be accurate for predicting diurnal performance of the NET facility. A battery of simulations were run for diurnal air exchange rates, the results of which are compared to gas tracer analysis tests performed during the Summer of 2011. A parametric study involving various attic ventilation area ratios was performed using the benchmarked prediction tool to show the effect of varying ventilation area ratios on the thermal and moisture-control capabilities of attics with standard construction, Above Sheathing Ventilation, and Radiant Barrier systems. The results of this study are based on the analysis of field data, benchmarked simulations, and parametric study on ventilation ratio effectiveness. Ventilation variation is shown to have only a minor effect on the moisture control and thermal performance of residential attic cavities. In comparison, attics equipped with radiant barrier foil or above sheathing ventilation provide a greater range of control over thermal and moisture infiltration.

▼ This study developed a 3D numerical model of a ventilation setup inside a Fiberglass Reinforced Plastic (FRP) boat-manufacturing plant, and simulated the flow inside this plant. The study also investigated two alternate ventilation systems, and compared the results with those for the existing ventilation system. Ventilation systems are installed in FRP boat-manufacturing plants to remove harmful contaminants, mainly styrene, emitted during manufacture of boats. Adopting a suitable ventilation system is an inexpensive way of reducing styrene exposure to workers and, hence, is investigated for an existing manufacturing plant. First, a 2D study of a typical ventilation system is carried out, with the goal to understand the general flow pattern inside the plant. Steady-state results established that styrene accumulates near the ground because it is denser than air, suggesting that a ventilation system should include a ground-level exhaust to remove much of the styrene. A subsequent 3D model of an actual ventilation setup in a manufacturing plant is developed based on data obtained from the National Institute for Occupational Safety and Health (NIOSH). Results from an unsteady simulation showed, again, that styrene, being heavier than air, stayed close to the floor. The average velocity in the working area of the boat was determined to be 0.65 m/s, suggesting little ventilation in the area. Also, after evaporation from the boat surface, styrene was being not forced towards the exhaust vents located downstream. Based on these results, two alternate ventilation systems are investigated. The first one involves ground-level exhausts near the working area to remove much of styrene. The second system involves inlet air blowers placed closer to ground, i.e., at 0.91 meters from the floor, as compared to 3.96 meters in the original system, to push styrene accumulating near the floor, towards the exhaust vents located downstream. Results predict that the first alternate ventilation system reduces styrene concentration by 57% at the breathing level of the workers. However, the ventilation in the working area improves only slightly, with an average velocity of 0.7 m/s. Also, styrene is still not forced to flow towards the exhaust vents as before. Meanwhile, in the second alternate ventilation system, styrene concentration at the breathing level of the workers increases by 1.7%. The air blowers are effective in directing most of the styrene downstream, but this flow is inhibited on its path, due to the formation of a strong re-circulation region near the working area. This causes greater mixing of styrene and air, thus increasing the prevailing styrene concentration. The average velocity in the working area is nearly 0.5 m/s, indicating that the air blowers should be brought closer to the boat to ventilate this region more effectively. The ventilation effectiveness defined as the ratio of styrene concentration at the exhaust vents to the styrene concentration at select indoor points, is compared for all three ventilation… Advisors/Committee Members: Ghia, Urmila (Advisor).

▼ The transition from mechanical ventilation (MV) to spontaneous ventilation during weaning is associated with hemodynamic alterations and autonomic nervous system (ANS) alterations (reflected by heart rate variability [HRV]). Although cardiac dysrhythmias are an important manifestation of hemodynamic alterations, development of dysrhythmias during MV and weaning and subsequent impact on length of MV has received little attention. The purposes of this dissertation were to 1) evaluate the relationship of heart rate variability (HRV) during weaning to the development of cardiac dysrhythmias and 2) determine the relationship of cardiac dysrhythmias to length of MV. A convenience sample of 35 patients (66.7% men; mean age 53.3 years) who required MV was enrolled in this study. Continuous 3-lead electrocardiographic data were collected for 24 hours at baseline during MV and for the first 2 hours during the initial weaning trial. HRV was evaluated using spectral power analysis. Twenty- seven patients out of 30 were exposed to a combination of pressure support (8-15 cm H2O) and continuous positive airway pressure 5 cm H2O during weaning trial. Three patients self- extubated and received supplemental oxygen through either a partial rebreathing or non-rebreathing mask. Low frequency (LF) power HRV decreased, while high frequency (HF) and very low frequency (VLF) power HRV did not change during weaning. Multiple regression analyses showed that LF and HF HRV were significant predictors of occurrence of ventricular and supraventricular ectopic beats during weaning, while VLF power predicted occurrence of ventricular ectopic beats only. The mean of occurrence of supraventricular ectopic beats per hour during weaning was double the mean at baseline, while the mean of ventricular ectopic beats per hour did not change. Mean number of supraventricular ectopic beats per hour during weaning was a significant predictor of length of MV. This dissertation has fulfilled an important gap in the evidence base for cardiac dysrhythmias during weaning from MV. Cardiac dysrhythmias and HRV alterations should be systemically evaluated during MV and weaning trials in order to decrease length of MV.

Les ventilateurs ont connu des progrès technologiques considérables grâce à l'application de concepts physiologiques, à l'électronique, à l'informatique et la miniaturisation. Leurs conceptions et performances intrinsèques, en revanche, ont pu rester inégales sur certains points. L'objectif de ce travail a été d'évaluer sur un banc d'essai, avec un protocole, adapté aux problématiques soulevées en pratique clinique, tous les ventilateurs de réanimation, transport et de ventilation non invasive de façon rigoureuse et reproductible. Les résultats montrent que 1) l'erreur sur le volume réellement délivré est très fréquente et correspond facilement à 1ml/kg de volume supplémentaire ; le VT indiqué sur les ventilateurs est inférieur au VT réellement délivré ; 2) les performances des nouveaux ventilateurs ne présentent pas d'améliorations significatives par rapport aux meilleurs ventilateurs testés en 2000; les ventilateurs à turbine sont identiques ou proches des meilleurs ventilateurs conventionnels ; 3) les ventilateurs dédiés à la ventilation non invasive montrent de meilleures performances pour s'adapter à la présence de fuites ; 4) la ventilation par percussion intra-pulmonaire superposée à la ventilation conventionnelle peut réduire l'apport de l'humidification, influencer les volumes administrés et induire une pression expiratoire positive intrinsèque. Les tests sur banc montrent une grande hétérogénéité des performances. Une veille technologique semble indispensable pour évaluer tout nouveau ventilateur

The ventilators have markedly improved thanks to progress in respiratory physiology, in informatics and miniaturization. However, their intrinsic performances remain unequal. The aim was to evaluate ventilators performances on reproducible bench test studies adapted to clinical questions. Tests show that 1) the error of really delivered volume is approximately 1 ml/kg of additional volume; the tidal volume (VT) indicated on the ventilators was lower than the real delivered VT ; 2) Performances of new ventilators are comparable to the best ventilators tested in 2000 ; turbine ventilators are quite similar to best conventional ventilators ; 3) The ventilators dedicated to non invasive ventilation showed better performances to cope with leaks 4) The intrapulmonary percussive ventilation superimposed on conventional ventilation can reduce humidity, increase volumes and can generate intrinsic positive expiratory pressure. The bench tests showed a large heterogeneity of performances. A technological watch seems essential to evaluate all new ventilators

La dysfonction diaphragmatique, au même titre que la neuromyopathie de réanimation qui touche les membres périphériques sont des causes fréquemment impliquées dans l'échec du sevrage de la ventilation mécanique. Des données suggèrent que ces deux atteintes sont le reflet d'une même affection ayant un tropisme respiratoire et locomoteur. Cette thèse met en évidence que la dysfonction diaphragmatique et la neuromyopathie de réanimation sont deux atteintes distinctes dont la coexistence est relativement faible. De plus, la dysfonction diaphragmatique a un impact délétère plus important sur le sevrage et le pronostic vital que la neuromyopathie de réanimation. Toutefois, le niveau de fonction diaphragmatique requis pour permettre une séparation du ventilateur est plus faible que le niveau de fonction définissant la dysfonction diaphragmatique. Ce travail montre également que l'exploration de la fonction diaphragmatique peut être simplifiée par l'utilisation de l'échographie et de l'électromyographie du diaphragme.

Diaphragm dysfunction and critical illness associated neuropathy and myopathy are frequently suspected to cause weaning failure from mechanical ventilation. Some data suggest that both may be gathered into a same entity with two localisations, respiratory and peripheral. This thesis highlights that diaphragm dysfunction and critical illness neuromyopathy are two distinct diseases that don’t frequently coexist. In addition, diaphragm dysfunction has a more severe impact on weaning outcome and prognosis than critical illness associated neuromyopathy and myopathy. However, the level of diaphragm function required to ensure safe mechanical ventilation discontinuation is lower than the level of diaphragm function defining diaphragm dysfunction. This work also shows that investigating diaphragm function may be simplified by the use of ultrasound and diaphragm electromyogram activity.

En ventilation assistée, les interactions patient-ventilateur, qui sont associés au pronostic, dépendent pour partie des algorithmes de ventilation. Objectifs : Caractériser l'intérêt potentiel des nouveaux algorithmes de ventilation dans l'optimisation des interactions patient-ventilateur : 1) en ventilation invasive, deux modes et leurs algorithmes nous ont semblé novateurs et nous avons cherché à personnaliser l'assistance du ventilateur en fonction de l'effort respiratoire du patient au cours de ces modes proportionnels : ventilation assistée proportionnelle (PAV+) et ventilation assistée neurale (NAVA) ; 2) en ventilation non-invasive (VNI) nous avons évalué si les algorithmes VNI des ventilateurs de réanimation et des ventilateurs dédiés à la VNI diminuaient l'incidence des asynchronies patient-ventilateur. Méthodes : 1) En PAV+ nous avons décrit un moyen de recalculer le pic de pression musculaire réalisée par le patient à chaque inspiration à partir du gain réglé et de la pression des voies aériennes monitorée par le respirateur. Nous avons alors évalué la faisabilité clinique d'ajuster l'assistance en ciblant un intervalle jugé normal de pression musculaire. 2) Nous avons comparé une titration de l'assistance en NAVA et en aide inspiratoire (AI) en se basant sur les indices d'effort respiratoire. 3 et 4) En VNI, nous avons évalué l'incidence des asynchronies patient-ventilateur avec et sans l'utilisation d'algorithmes VNI : sur banc d'essai au cours de conditions expérimentales reproduisant la présence de fuites autour de l'interface ; en clinique chez des patients de réanimation. Résultats : En PAV+, ajuster le gain dans le but de cibler un effort respiratoire normal était faisable, simple et souvent suffisant pour ventiler les patients depuis le sevrage de la ventilation mécanique jusqu'à l'extubation. En NAVA, l'analyse des indices d'effort respiratoire a permis de préciser les bornes d'utilisation et de comparer les interactions patient-ventilateur avec l'AI dans des intervalles d'assistance semblables. En VNI, nos données pointaient l'hétérogénéité des algorithmes VNI sur les ventilateurs de réanimation et retrouvaient une meilleure synchronisation patient-ventilateur avec l'utilisation de ventilateurs dédiés à la VNI pour des qualités de pressurisation par ailleurs identiques. Conclusions : En ventilation invasive, personnaliser l'assistance des modes proportionnels optimise les interactions patient-ventilateur et il est possible de cibler une zone d'effort respiratoire normale en PAV+. En VNI, les ventilateurs dédiés améliorent la synchronisation patient-ventilateur plus encore que les algorithmes VNI sur les ventilateurs de réanimation, dont l'efficacité varie grandement selon le ventilateur considéré.

Trabalho Final de Mestrado para obtenção do grau de Mestre em Engenharia Civil na Área de Especialização de Edificações

A qualidade do ar interior de edifícios é uma preocupação em crescendo na atual sociedade. Proporcionar um ambiente adequado à permanência de ocupantes é cada vez mais importante e para tal é necessário alterar, melhorar, desenvolver ideias/medidas capazes de oferecer um sistema de ventilação que cumpra os requisitos propostos pela regulamentação europeia e portuguesa. Um sistema de ventilação mista apresenta-se neste contexto, como uma solução viável capaz de preencher tais requisitos de ventilação. O objetivo fundamental deste trabalho é o estabelecimento de regras de dimensionamento aplicadas em fogos de edifícios reais situados em Lisboa relativamente a esquemas de ventilação que pressuponham uma correta admissão/exaustão de ar através de uma ventilação mista que permita um ambiente confortável para os ocupantes. O cálculo dos vários fluxos de ar será efetuado com um software que recorre a modelos assentes sobre redes multicompartimentos, o programa CONTAM. A origem e o caudal de ar que entra em cada divisão do edifício será analisada e comparada com as exigências da regulamentação portuguesa. Através da análise de resultados, resultante da vasta campanha de simulações, será demonstrada a viabilidade do sistema de ventilação mista e estabelecer-se-á um conjunto de regras claras a cumprir por um projeto de ventilação de forma a satisfazer exigências normativas no que diz respeito à ventilação.

The indoor air quality of buildings is a growing concern in today's society. Providingan appropriate internal environment for residents and occupants is of vital importance. Creating such an environment requires changes, improvements as well as developing ideas and applying measures to provide a ventilation system that meetthe requirements proposed by European and Portuguese legislation. A mixed ventilation system is presented in this context, as a viable solution capable of fulfilling such ventilation requirements. The fundamental objective of this work is to establish design rules applied in real buildings, located in Lisbon, for ventilation schemes that involve a correct intake / exhaust air through a mixed ventilation. The balancing of the air flows is performed with software that uses models based on multi chamber networks, CONTAM program. The source and the air flow entering each building division is analysed and compared to the requirements of the Portuguese regulations. Applying the analysed results, the outcome of an extensive campaign, simulations will demonstrate the feasibility of the mixed ventilation system. In addition, a clearset of rules will be established, which can be followed in a ventilation design in order to meet regulatory requirements.

Dissertação de Mestrado em Enfermagem Médico-Cirúrgica apresentada na Escola Superior de Saúde do Instituto Politécnico de Viana do Castelo

A comunicação permite relacionarmo-nos com os outros, tornando-nos um ser social e constitui um pilar importante onde assenta a humanização dos cuidados de saúde. A pessoa com falência de funções vitais que necessita de ventilação artificial não emite sons, devido à presença de um tubo endotraqueal, limitando a capacidade de comunicar, justamente em momentos de maior fragilidade, quando corre risco de vida. É neste contexto que surge este estudo, cujo interesse foi despoletado durante um estágio numa unidade de cuidados intensivos, onde tive a oportunidade de cuidar de doentes críticos ventilados e, por isso, impedidos de comunicar verbalmente. Neste sentido, desenvolvemos um estudo qualitativo de caráter exploratório descritivo, cujo objetivo foi compreender o processo de comunicação entre o enfermeiro e a pessoa em situação crítica submetida a ventilação mecânica invasiva, de modo a contribuir para a melhoria da qualidade de cuidados. Como estratégia de recolha de dados optámos pela entrevista semiestruturada e pela observação participante a um grupo de dez enfermeiros de uma unidade de cuidados intensivos de um hospital da zona Norte de Portugal.Após a análise dos dados obtidos através da técnica de análise de conteúdo, os resultados foram organizados em torno de cinco áreas temáticas: modos de comunicar; finalidades da comunicação enfermeiro/doente; fatores que interferem no processo de comunicação; estratégias mobilizadas pelo enfermeiro no processo de comunicação e sugestões para otimizar a comunicação. Emergiram as seguintes conclusões: Na interação enfermeiro/doente são mobilizados os modos de comunicar-verbal e nãoverbal. Enquanto os enfermeiros utilizam preferencialmente a palavra falada para comunicar com o doente, associada grande parte das vezes a formas de comunicação não-verbal, o doente comunica com o enfermeiro principalmente através de formas de comunicação não-verbal, estando estas dependentes da descodificação da mensagem por parte do enfermeiro. Das finalidades da comunicação enfermeiro/doente evidencia-se o explicar dos procedimentos que vão executar e avaliar as necessidades do doente. Dos diversos fatores que interferem na comunicação enfermeiro/doente destacamos o estado de consciência/nível de sedação do doente, a experiência profissional do enfermeiro em UCI e o ambiente da própria unidade. Emergiram sugestões que atribuem particular importância ao desenvolvimento de competências comunicacionais do enfermeiro e à partilha de relatos das experiências dos doentes submetidos a ventilação mecânica invasiva. Neste sentido perspetivamos mudanças que impliquem um maior investimento na formação dos profissionais neste domínio e um maior envolvimento da família nos cuidados fomentando espaços de reflexão que ajudem a aproximar o cuidador da pessoa cuidada.

Introdução: Limitação ao fluxo e hiperinsuflação dinâmica são fteqüentemente observadas em pacientes com DPOC. A capacidade inspiratória (CI) tem sido sugerida como um método simples para verificar as alterações no volume pulmonar expiratório final e hiperinsuflação pulmonar. Entretanto, poucos estudos verificaram se a aplicação de pressão positiva contínua nas vias aéreas (CP AP) poderia diminuir a hiperinsuflação pulmonar. Objetivo: Verificar os efeitos imediatos da CP AP no volume pulmonar expiratório final em pacientes com DPOC estável. Método: Trata-se de um estudo prospectivo, com 21 pacientes, idade 63 :I: 9 anos, com volume expirado forçado no primeiro segundo de 40,7 :I: 11,7%, que foram submetidos a um teste gradual de CP AP (4, 7 e 11 cmH20 - Drãger SA VINA ventilator). A CI foi mensurada pela espirometria, antes e depois de cada valor de CPAP. Nos pacientes nos quais os três valores de CPAP resultaram em redução da CI, uma pressão de 2 cmH20 também foi aplicada. Para cada paciente, um valor de CP AP "ótimo" foi definido como o valor correspondente a melhor CI obtida com o teste gradual da CP AP. Este valor "ótimo" de CP AP foi, então, aplicado por 10 min e uma espirometria foi posteriormente realizada. Resultados: Durante o teste gradual da CPAP, seis pacientes (grupo não respondedor) não apresentaram qualquer melhora na CI. Quando o valor de CP AP "ótimo" foi então aplicado nesses indivíduos, foi observado piora significativa da CI de 83,7:1: 19,4% para 74:1: 22,8% (p = 0,0341). Em 15 pacientes (grupo respondedor), a CI aumentou significativamente de 68,6 :I: 17,9% para 75,3 :I: 18,0% (p = 0,0002). A capacidade vital lenta foi o único parâmetro espirométrico que também aumentou após a CPAP "ótima" no grupo respondedor (240 rnL, 7,4% do valor predito, p <0,01). Nenhuma diferença significativa foi observada após a CP AP "ótima" nos pacientes com limitação ao fluxo expiratório (CI pré-CPAP :S 80% do valor predito) versus pacientes não limitados ao fluxo expiratório (CI pré-CPAP >80% do valor predito). Entretanto, os pacientes com enfisema pulmonar e CI:S 80%,do valor predito demonstraram um aumento significativo na CI após a CPAP "ótima" (220 rnL, 8,9% do valor predito, p <0,01). Conclusão: A CPAP pode aumentar a capacidade inspiratória em pacientes selecionados, sugerindo redução no volume pulmonar expiratório final, conseqüente da diminuição na hiperinsuflação pulmonar

Bachground: Flow limitation and dynamic hyperinflation are common findings in COPD patients. Inspiratory capacity (IC) has been proposed as a simple method to assess changes in end-expiratory lung volume (EEL V) and lung hyperinflation. However, few studies verified if the application of continuous positive airway pressure (CP AP) could decrease lung hyperinflation. Objective: To assess the immediate effect of the CP AP in EEL V in stable COPD patients. Method: Prospective study of 21 stable COPD patients, age 63 :!: 9 years, with forced expiratory volume in first second (FEV1) of 40.7 :I: 11.7%, who were submitted to the gradual test of…

INTRODUCTION: Exercise as a form of stress stimulates inflammatorycytokines secretion. IL-6 is a major modulator of stress. Patients who fail aspontaneous breathing trial develop more cardiopulmonary stress than those whosucceed. Similarly, resistive breathing results in systemic IL-6 increase.OBJECTIVES: To assess the impact of withdrawing ventilator support onsystemic IL-6 in ventilated patients during a spontaneous breathing trial and tocompare the IL-6 response between weaning failure and success.METHODS: In 13 critically ill patients who failed and in 18 who succeededweaning from mechanical ventilation hemodynamic, oxygenation and respiratoryparameters as well as pro and anti-inflammatory cytokines were measured onmechanical ventilation and during a 2 hour spontaneous breathing trial.RESULTS: Plasma concentrations of IL-6 increased in all patients duringspontaneous breathing trial. The increase of IL-6 was higher in patients who failed thespontaneous breathing trial (from 46.3±7.1 to 61.31±9.4 pg/ml) compared to thosewho succeeded the trial (from 59.9±71.8 to 67.8±86.2 pg/ml). Respiratory frequency/tidal volume increased from 30.2±7.8 to 74.2±44 and from 30±10.1 to110±37.6breaths/minute /liter in succeeded and failed patients respectively. Asignificant correlation was not observed between IL-6 increase and frequency/tidalvolume ratio increase. IL-10 did not change significantly.CONCLUSIONS: In mechanically ventilated patients who fail a spontaneousbreathing trial systemic IL-6 levels increase during the trial. IL-6 increase was higherin spontaneous breathing trial failure, compared to success. Therefore, IL-6 seems toplay a role in the stress response associated with spontaneous breathing in patientswho are weaned from mechanical ventilation.

▼ The term angiogenesis is used to describe the formation of new capillaries from existing ones. In response to various stimuli acting both on luminal and abluminal surface of the existing vessels, the basic membrane and the extracellular matrix underlying the endothelium are dissolved allowing the endothelial cells to migrate into extravascular space. There they proliferate and form sprouts that subsequently acquire newly formed basic membrane and are encircled by pericytes. The sprouts become functional on anatomic connection to the already existing segments of capillary network. Specific angiogenic growth factors have been well documented to initiate and promote this extremely complex process. Vascular Endothelial Growth factor (VEGF) stimulates the migration and proliferation of endothelial cells and smooth muscle cells as well as the production of proteases that are essential for the dissolution of the basic membrane of the vessels. Basic Fibroblast Growth Factor (bFGF) is a potent mitogenic factor for endothelial cells, smooth muscle cells and fibroblasts. It also upregulates VEGF and NO. Transforming Growth Factor β1 (ΤGF- β1), mainly produced by activated endothelial cells, promotes angiogenesis by recruiting pericytes to complete and stabilize the newly formed capillaries. It has been well documented in numerous animal and human studies that increased muscle activity consists a powerful stimulus for the formation of new capillaries in both skeletal muscles and heart muscle in order to meet their increased metabolic demands. Agiogenesis in response to increased muscle activity has been attributed to either metabolic stimuli, such as tissue hypoxia, or mechanical forces. The latter can be classified as (a) hemodynamic, acting on the luminal surface of the vessels i.e. wall tension and shear stress, due to increased blood flow and (b) extravascular, acting on the abluminal surface, as a result of muscular fiber contraction and relaxation. Mechanical forces associated with shortening and relaxation of the myocytes are imparted to the microvascular network via the extracellular matrix and connective tissue elements. Any mechanical injury caused to the endothelium by the above stimuli is sufficient to initiate the process of angiogenesis, through the realease of the angiogenic factors. The diaphragm, the main respiratory muscle that is longlife continuously and rhythmically contracting demonstrates characteristics of the skeletal muscles. It has been shown in animal and human studies that it exhibits the same angiogenic response to increased workload as locomotive muscles. Siafakas et al demonstrated increased VEGF and bFGF mRNA diaphragmatic levels in rats after 1 hour of increased ventilation due to hypercapnia and hypoxaemia, in contrast to animals with paralysed diaphragms. Increased mRNA expression of the VEGF was also found in the diaphragm of COPD and obese patients, compared to normal subjects, due to consequent increased respiratory workload. The aim of the present study was to assess the gene…

▼ The overall goal of this thesis was to develop a dry powder delivery system for patients on mechanical ventilation. The studies were divided into two parts: the formulation development and the device design. The pulmonary system is an attractive route for drug delivery since the lungs have a large accessible surface area for treatment or drug absorption. For ventilated patients, inhaled drugs have to successfully navigate ventilator tubing and an endotracheal tube. Agglomerates of drug nanoparticles (also known as `NanoClusters') are fine dry powder aerosols that were hypothesized to enable drug delivery through ventilator circuits. This Thesis systematically investigated formulations of NanoClusters and their aerosol performance in a conventional inhaler and a device designed for use during mechanical ventilation. These engineered powders of budesonide (NC-Bud) were delivered via a Monodose® inhaler or a novel device through commercial endotracheal tubes, and analyzed by cascade impaction. NC-Bud had a higher efficiency of aerosol delivery compared to micronized stock budesonide. The delivery efficiency was independent of ventilator parameters such as inspiration patterns, inspiration volumes, and inspiration flow rates. A novel device designed to fit directly to the ventilator and endotracheal tubing connections and the Monodose® inhaler showed the same efficiency of drug delivery. The new device combined with NanoCluster formulation technology, therefore, allowed convenient and efficient drug delivery through endotracheal tubes. Furthermore, itraconazole (ITZ), a triazole antifungal agent, was formulated as a NanoCluster powder via milling (top-down process) or precipitation (bottom-up process) without using any excipients. ITZ NanoClusters prepared by wet milling showed better aerosol performance compared to micronized stock ITZ and ITZ NanoClusters prepared by precipitation. ITZ NanoClusters prepared by precipitation methods also showed an amorphous state while milled ITZ NanoClusters maintained the crystalline character. Overall, NanoClusters prepared by various processes represent a potential engineered drug particle approach for inhalation therapy since they provide effective aerosol properties and stability due to the crystalline state of the drug powders. Future work will continue to explore formulation and delivery performance in vitro and in vivo. Advisors/Committee Members: Berkland, Cory (advisor), Stella, Valentino J.

▼ Mechanical ventilation (MV) therapy has been utilised in the intensive care unit (ICU) for 50 years to treat patients with respiratory illness by supporting the work of breathing, providing oxygen and removing carbon dioxide. MV therapy is utilised by 30-50% of ICU patients, and is a major driver of increased length of stay, increased cost and increased mortality. For patients suffering from acute respiratory distress syndrome (ARDS), the optimal MV settings are highly debated. ARDS patients suffer from a lack of recruited alveoli, and the application of positive end expiratory pressure (PEEP) is often used to maintain recruitment to maximise gas exchange and minimise lung damage. However, determining what level of PEEP is best for the patient is difficult. In particular, it involves a complex trade off between patient safety and ventilation efficacy. Currently, no clinical protocols exist to determine a patient-specific “best” PEEP. Model-based approaches provide an alternative patient-specific method to help clinical diagnosis and therapy selection. In particular, model-based methods can utilise a mix of both engineering and medical principles to create patient-specific models. The models are used for optimising ventilation settings and providing greater physiological insight into lung status than is currently available. Two model-based approaches are presented here. First, a quasi-static, minimal model of lung mechanics is presented based solely on fundamental lung physiology and mechanics. Secondly, a model of dynamic functional residual capacity (dFRC) is developed and presented based on model-based status of lung stress and strain. These models are validated with retrospective clinical data to evaluate the potential of such model-based approaches. Finally, the models are further validated with real time clinical data over a broader spectrum of pressure-volume ranges than prior studies to evaluate the clinical viability of model-based approaches to optimise MV therapy. When validated with real-time clinical trials data, the outputs of the recruitment model provide a range of optimal patient-specific values of PEEP based on different clinically and physiologically derived criteria. The recruitment model is also shown to have the ability to track the disease state of ARDS over time. The dFRC model introduces the PEEP stress parameter, β, which represents a unique population constant. The dFRC model suggests that clinically reasonable estimates of dFRC can be achieved by using this novel value of β, rather than the current, potentially hazardous, methods of deflating the lung to atmospheric pressure. Finally, a third model, combining the principles of recruitment and gas exchange is introduced. The combined model has the ability to estimate cardiac output (CO) changes with respect to PEEP changes during MV therapy. In addition, the model relates the coupled areas of circulation and pulmonary management, as well as linking these MV decision support models to oxygenation based clinical endpoints. A proof…
