Comparison of two weaning strategies using either non-synchronized biphasic ventilation (mode 'Biphasic Positive Airway Pressure Ventilation' (BIPAP)) or assisted inspiratory ventilation (AI): randomized feasibility study.
Zusammenfassung der Studie
Patients suffering from acute respiratory failure often require ventilatory assistance via a machine (respirator or ventilator) to ensure adequate oxygen supply. Once the patient's health status has improved, the goal is to wean them off ventilation by gradually reducing the support provided by the machine (weaning phase). The ventilatory mode commonly used during weaning is assisted inspiratory ventilation (AI). In our research project, we want to demonstrate that it is possible to perform weaning with another mode of ventilation called Biphasic Positive Airway Pressure (BIPAP), using a clinical algorithm specifically developed for the study. This BIPAP mode indeed has theoretical advantages over the AI mode as it does not require synchronization of the patient's breathing with the ventilator, a synchronization that is often difficult to ensure optimally.
