Incidence and Risk Factors of Weaning-induced Cardiac Dysfunction: Results From a Multicenter, Observational Study

A spontaneous breathing trial (SBT) is used to identify patients who are likely to fail liberation from mechanical ventilation. The test can be done according to the usual modalities of the participating centre, following the international recommendations, meaning either by disconnecting the endotracheal tube from the ventilator and connecting it to a source of oxygen through the T-tube or by setting pressure support with low positive end-expiratory pressure (PEEP). The choice of the method will not be determined according to the participation in this study but will be done according to the habits of the participating centre.
