Physiological comparison of noninvasive ventilation and CPAP on inspiratory efforts after extubation in critically ill patients with morbid obesity: a post-hoc analysis.

ABSTRACT:

Background

No study has evaluated the inspiratory effort in patients with obesity immediately after extubation according to the noninvasive ventilatory support used. We aimed to determine, in critically ill patients with morbid obesity, whether Non Invasive Ventilation applied with facial mask with Pressure Support above Positive End-Expiratory Pressure (PSV-PEEP) may reduce patient inspiratory efforts to a greater extent than Continuous Positive Airway Pressure (CPAP) after extubation.

Methods

We conducted a post-hoc analysis based on data from a physiological study involving consecutive patients with morbid obesity prior to extubation. Flow, airway, esophageal, and gastric pressure signals were then recorded 20 min after extubation under three distinct conditions: (1) stan
