Abstract:

Mechanical ventilation is a life-saving therapy for patient treatments in Intensive Care Units (ICUs). The management of mechanical ventilation is a very challenging task. It has long been recognised that a computer-based bedside decision support system is r desirable for optimal ventilator management in ICUs. In this thesis, a closed-loop adaptive model-based ventilator management decision support system is developed. A previously developed ventilated patient mathematical model is further improved and extended with respect to the model parameter estimation and the simulation of the patients a

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 éval

Palliativ vård innebär att förbättra livskvalitet för personer med livshotande kronisk sjukdom och dess närstående. De fyra hörnstenar som den palliativa vården vilar på är symtomkontroll, kommunikation, teamarbete och närståendestöd. Sjuksköterskor inom palliativ vård har till uppgift att tillsammans med teamet förebygga, observera, behandla och lindra symtom för både patient och närstående. Amyotrofisk lateralskleros är en motorneuronsjukdom som påverkar kroppens alla muskler.

Abstract:

La qualité du sommeil des patients en soins intensifs est mauvaise, avec une fragmentation du sommeil, une diminution de la phase de sommeil paradoxal et une redistribution des temps de sommeil durant la période diurne. Si le bruit semble une cause évidente, il ne rendrait compte que de 20% des perturbations du sommeil dans ce contexte (Freedman et al. 1999; Gabor et al. 2003). La ventilation mécanique apparaît comme une autre source d'altération de la qualité et de la quantité de sommeil chez les patients en soins intensifs (Meza et al. 1998; Cooper et al. 2000; Parthasarathy et Tobin, 2004;)

Abstract:

Mechanical ventilation is life saving as a respiratory support for preterm infants with respiratory distress syndrome. There is good evidence now that any form of volume-targeted modality of mechanical ventilation is superior over pressure-targeted modality to reduce chronic lung disease and death. It is perceived by minimising the duration of mechanical ventilation would reduce the exposure to positive pressure breaths and thereby could reduce long term morbidities such as chronic lung disease. An area of lacunae is defining what is weaning on mechanical ventilation. Whilst most clinicians wi

Abstract:

In patients affected by acute respiratory failure or acute respiratory distress syndrome (ARDS) the leading cause of death is failure of different vital organs other than the lungs, so called multiple organ dysfunction syndrome (MODS). The abdominal organs have a crucial role in the pathogenesis of this syndrome. There is a lack of knowledge regarding the mechanisms by which mechanical ventilation can affect the abdominal compartment. One hypothesis is that mechanical ventilation can interfere with abdominal fluid balance causing edema and inflammation. We addressed the question whether differ

Background: Preterm infants with gestational age (GA) <= 32 weeks require endotracheal tube mechanical ventilation (ETT-MV) during their first few days of life. These infants are quickly weaned from ETT-MV and extubated to some type of noninvasive ventilatory support; usually Nasal Continuous Positive Airway Pressure (CPAP) or non-synchronized Nasal Intermittent Positive Pressure Ventilation (NIPPV). Currently, there is no evidence to select one mode over another. The aim of this thesis was to compare cardiorespiratory behavior of infants undergoing nasal CPAP and NIPPV by evaluating the immed

Abstract:

Afin de concevoir des systèmes énergétiques (chauffage, rafraîchissement, ventilation) et de prédire leurs performances en terme de confort thermique et de qualité de l'air, l’estimation des détails des écoulements et des transferts de chaleur au sein des locaux représente un enjeu important. Les modèles zonaux, qui reposent sur un découpage d’une pièce en un petit nombre de sous-volumes permettent d'appréhender l'hétérogénéité des caractéristiques thermo-aérauliques d'un espace avec des temps de calcul modérés. Ils correspondent à un bon compromis entre simplicité des modèles et volumes d'inf

Abstract:

INTRODUÇÃO: O desmame da ventilação mecânica é um processo complexo que requer avaliação e interpretação de parâmetros clínicos objetivos e subjetivos. O atraso no processo de desmame pode expor o paciente a um desconforto desnecessário, aumentar o risco de complicações e custos. Os modos de desmame automatizados podem acelerar a extubação e diminuir a carga de trabalho da equipe da UTI. Há diversos modos automatizados de desmame disponíveis que foram avaliados, separadamente, em populações selecionadas, com resultados divergentes em relação ao desmame convencional. No entanto, os modos automá

Furthermore, the secondary and tertiary hospitals are under severe strain to accept all the referrals from rural hospitals. Many of these infants require intubation and ventilation with a resuscitation bag which must be sustained for hours until the transport team arrives. Not only is lung damage inflicted by the prolonged ventilation, but transferring the infant by helicopter and ambulanc
