Intelligent volume assured pressure support (iVAPS) vs. spontaneous/timed mode as a weaning strategy for intubated COPD patients with acute exacerbation.

Introduction: Noninvasive positive-pressure ventilation (NPPV) is applied to facilitate weaning process and decrease complications associated with prolonged intubation. Interest has emerged in using Intelligent Volume Assured Pressure Support (iVAPS) to facilitate earlier removal of an endotracheal tube.

Material And Methods: This study was conducted to compare the effectiveness of iVAPS versus standard Spontaneous/timed (S/T) mode in facilitating weaning process of mechanically ventilated chronic obstructive pulmonary disease (COPD) in acute exacerbation.
