all patients with weaning criteria, spontaneous breathing test will be done. If patient is able to have spontaneous ventilation with maximum of 16 cm of H2O of pressure support, he could be included in the study. The nocturnal ventilation mode will be randomised between pressure controlled ventilation and pressure support ventilation with the same pressure support than during the day. We will follow the quality and quantity of sleep with continue polysomnography. Indeed, patien...
In this study, we want to compare two different kinds of artificial ventilation to see if one encourages faster weaning from breathing support and if one provides better sleep quality. These artificial ventilation types are: 1. Pressure support ventilation; the standard ventilation that we use for the patients in the Respiratory Acute Care Unit. Pressure support ventilation ventilators use constant air pressure to assist patients with their breathing. 2. P...
The purpose of this research study is to compare difference between breathing by oneself or with the partial help from an anesthesia machine in children under general anesthesia.
This study is looking at whether there is a difference in outcomes using two different types of breathing support in those patients who have chronic respiratory failure (patients who under-breathe). There is little data to demonstrate which mode of ventilation is better in terms of physiological outcomes and outcome data relating to patient symptoms. We hypothesize that one type of breathing support: pressure support ventilation would be more comfortable for patients as...
This is a prospective randomized cross over study of healthy volunteers undergoing continuous positive airway pressure ventilation via a noninvasive ventilation (NIV) mask with and without the addition of nasal cannulas. Mask leak will be measured by the ventilator after 60 seconds of spontaneous resting ventilation, with each subject serving as his or her own control.
The purpose of this research study is to compare difference between breathing by oneself or with the partial help from an anesthesia machine in infants under general anesthesia. Hypothesis: Infants undergoing general anesthesia with a PLMA™ will be better ventilated (improved breathing) with the help of the breathing machine versus breathing on their own.
Atelectasis and redistribution of ventilation towards non-dependent lung zones are a common side effects of general anesthesia. Spontaneous breathing activity (SBA) during mechanical ventilation may avoid or reduce atelectasis, improving arterial oxygenation; however, it is unclear whether these effects play a significant role during general anesthesia in patients with healthy lungs. Earlier studies on ventilation during general anesthesia had to rely on computed tomography (C...
The investigator will compare the feasibility of manual ventilation and pressure-controlled mechanical ventilation during facemask ventilation in children. The hypothesis is that the incidence of gastric insufflation would be lower during pressure-controlled mechanical ventilation when compared to manual ventilation.
Rationale Studies show that about a third of all postoperative complications are due to cardiovascular reasons. Furthermore it was shown that more than 50% of postoperative deaths are associated with severe cardiovascular incidents. After surgical interventions seriously ill patients are transferred to intensive care units and mechanically ventilated. However there is not much evidence about the impact of mechanical ventilation on the cardiovascular system and cardiovascular co...
Mechanical ventilation has been known to produce changes in the flow of blood through the major blood vessels in the body. These changes may go undetected, but with continuous arterial blood pressure measurements, changes in the arterial waveform can be visualized. Although we know that these arterial pressure variations occur during mechanical ventilation, little is known about the effects of various modes of mechanical ventilation on these changes. The most common modes of ve...
Noninvasive ventilation is increasingly used method of respiratory management in both the emergency room and critical care. Noninvasive ventilation delivers mechanically assisted breaths without the placement of an artificial airway and has become an important mechanism of ventilator support inside and outside the intensive care unit. Noninvasive ventilation is further subdivided into negative pressure ventilation which is the iron lung, first used in 1928 and the Hayek oscill...
It is controversial as to which ventilation mode is better in one-lung ventilation(OLV), volume controlled ventilation(VCV) or pressure controlled ventilation(PCV). This study was designed to figure out if there was any difference between these two modes on oxygenation and postoperative complications under the condition of protective ventilation(PV).
Trial to Study Intubation Rates of Non-invasive Ventilation Using Pressure Support Ventilation (PSV) Versus Adaptive Support Ventilation (ASV) Mode in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease
The clinical course of chronic obstructive pulmonary disease (COPD) is associated with recurrent episodes of exacerbation that results in respiratory failure. The treatment of respiratory failure is supportive and involves inhalation bronchodilators along with systemic steroids. In few cases the management of acute respiratory failure requires positive pressure ventilation (non-invasive or invasive). The use of NIV in acute exacerbation of COPD has resulted in significant reduc...
This is a comparative study of duration of respiratory weaning between adaptive support ventilation and succession of controlled ventilation then spontaneous ventilation for patients after surgery.
The purpose of this study is to demonstrate that mechanical ventilation guided by the diaphragm EMG signal (also know as neurally adjusted ventilatory assist [NAVA]) is superior compared to pressure support and pressure control ventilation.
The aim of this study is to evaluate the ventilator settings advice given by the BEACON care system in fitting with best level of support in patient under mechanical ventilation in Pressure Support mode.
Adaptive support ventilation (ASV) is a closed loop ventilation mode that can act both as pressure support (PSV) and pressure controlled (PCV) ventilation. Weaning with ASV shows promising results mainly in post-cardiac surgery patients. The aim of this randomized controlled study was to test the hypothesis that weaning with ASV could reduce the weaning duration in patients with chronic obstructive pulmonary disease (COPD) when compared with PSV.
The aim of this multicenter, randomized controlled trial is to evaluate the weaning time from mechanical ventilation comparing non-variable PSV, variable PSV, and Smart CareTM. This study is a multicenter randomized controlled open trial comparing variable, non-variable pressure support ventilation and Smart CareTM in patients receiving mechanical ventilation for more than 24 hours who are able to be weaned. The aim of the study is to determine the duration of weaning from me...
Synchronism of gas flow delivered by the ventilator and muscular effort of the patient will be studied during two kinds of ventilation. The first one is the proportional assisted ventilation during which the gas flow is theoretically adapted to the patient's muscular effort within the breath. The second is the pressure support ventilation during which the gas flow is delivered to maintain the inspiratory pressure stable. The hypothesis is that the first mode allows a better syn...
Sevoflurane inhalational anesthetic has got pulmonary effects such as bronchodilatation. These effects could be of interest in intensive care patients ventilated in pressure support ventilation mode. The purpose of this study is to evaluate mechanical respiratory effects of sevoflurane administered through a new specific heat and moister exchanger called the Anesthetic Conserving Device (AnaConDa®) in pressure support ventilation in intensive care patients. In fact, dead space...
This study aims to investigate the feasibility of a driving pressure limited mechanical ventilation strategy compared to a conventional strategy in patients undergoing one-lung ventilation during Video-assisted thoracoscopic lobectomy.
To assess the potential benefits on mechanical ventilation plateau pressure of pressure controlled mode versus volume controlled mode for laparoscopic bariatric surgery in obese patients (BMI > 35). High plateau pressures encountered in obese patients due to their reduced pulmonary compliance could be lowered using pressure controlled mechanical ventilation.
General anesthesia has been demonstrated to have a negative impact on lung function. Both surgery and patient position influence the perioperative lung function. Laryngeal mask airway (LMA) has been proved to be safe and efficient to maintain the airways patent during general anesthesia. Pressure support ventilation (PSV) with LMA is routinely used in clinical practice. The aim of the present trial is to characterize perioperative changes in lung volume, ventilation inhomogenei...
This study aims to prove that driving pressure limited ventilation is superior in preventing postoperative pulmonary complications to existing protective ventilation.
This is a prospective randomized cross over study of healthy volunteers comparing end-tidal oxygen concentration among subjects undergoing continuous positive airway pressure ventilation via a noninvasive ventilation (NIV) mask with and without the addition of nasal cannulas.
