Although mechanical ventilation is necessary to sustain life in such situations, it can induce weakness of the respiratory muscles which may lead to prolonged dependence on the ventilator. Prolonged dependence on mechanical ventilation is associated with increased mortality, morbidity and costs to the healthcare system. Thus, a main goal of assisted mechanical ventilation is to reduce the patient's respiratory distress while maintaining some respiratory muscle activity. To attain this goal, the amount of ventilator assistance should theoretically be adjusted to target normal or reasonable levels of respiratory effort.\n\nModes of Mechanical Ventilation:\n\nProportional assist ventilation with load-adjustable gain factors (PAV+) is a mode of mechanical ventilation which delivers assistance to breathe in proportion to the patient's effort. The proportional assistance, called the gain, can be adjusted by the clinician to maintain the patient's respiratory effort or workload within a reasonable range. This is the only mode of ventilation which allows for measurement and targeting of a specific range of respiratory muscle activity by the patient.\n\nPressure support ventilation (PSV) is a mode of ventilation which is considered the current standard of care for assisting breathing of patients during the recovery phase of acute respiratory failure. Several studies have shown short term advantages of PAV over PSV, including improved patient-ventilator synchronization, improved adaptability to changes in patient effort, and improved sleep quality.\n\nGoal of this Randomized Controlled Trial:\n\nTo demonstrate that for patients with acute respiratory failure, ventilation with PAV+, being more physiological, will result in a shorter duration of time spent on mechanical ventilation than ventilation with PSV."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'A staged enrolment process will be used to identify patients eligible to be enrolled and randomized in the study.
