Background During ventilatory assistance, optimization of settings is critical to allow a personalized support and avoid over- or under-assistance. But little data are available in clinica...
Esophageal pressure measurements in surgical patients requiring mechanical ventilation during abdominal laparoscopic or robotic surgeries requiring intra-abdominal insufflation.
The use of esophageal balloon catheters, which use esophageal pressure as a surrogate measurement for transpleural pressure, shows promise in improving outcomes of patients with severe acu...
Introduction In patients assisted by mechanical ventilation, the Work Of Breathing (WOB) is shared between the patient and the ventilator. During weaning from mechanical ventilation, the W...
The investigator will compare the feasibility of manual ventilation and pressure-controlled mechanical ventilation during facemask ventilation in children. The hypothesis is that the incid...
Appropriate mechanical ventilation and prevention of alveolar collaps is mainly dependent on transpulmonary pressure TPP. TPP is assessed by measurement of esophageal pressure EP, largely influenced b...
Different mechanical ventilation settings are known to affect lung preservation for lung transplantation. Measurement of particle flow in exhaled air may allow online assessment of the impact of venti...
Acute and chronic respiratory failures require immediate diagnosis and preferably individualized ventilation therapy. If possible, non-invasive ventilation should be considered to avoid complications ...
To compare a time-controlled adaptive ventilation strategy, set in airway pressure release ventilation mode, versus a protective mechanical ventilation strategy in pulmonary and extrapulmonary acute r...
Esophageal manometry has shown its usefulness to estimate transpulmonary pressure, that is lung stress, and the intensity of spontaneous effort in patients with acute respiratory distress syndrome. Ho...
Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.
A method of mechanical ventilation in which pressure is maintained to increase the volume of gas remaining in the lungs at the end of expiration, thus reducing the shunting of blood through the lungs and improving gas exchange.
Non-therapeutic positive end-expiratory pressure occurring frequently in patients with severe airway obstruction. It can appear with or without the administration of external positive end-expiratory pressure (POSITIVE-PRESSURE RESPIRATION). It presents an important load on the inspiratory muscles which are operating at a mechanical disadvantage due to hyperinflation. Auto-PEEP may cause profound hypotension that should be treated by intravascular volume expansion, increasing the time for expiration, and/or changing from assist mode to intermittent mandatory ventilation mode.

Mechanical devices used to produce or assist pulmonary ventilation.
Mechanical ventilation delivered to match the patient's efforts in breathing as detected by the interactive ventilation device.
