Abstract
Adaptive support ventilation (ASV) is a dual control mode, using measured dynamic compliance and time constant, with an automated adjustment of tidal volume and respiratory rate combined to meet the preset minute ventilation. The purpose of this study was to evaluate the effectiveness of (ASV) in restoring air flow stability, decrease work of breathing and improving dys-synchrony in ventilated patients with variable airway resistance.

Adaptive support ventilation (ASV) is a dual control mode, using measured dynamic compliance and time constant, with an automated adjustment of tidal volume and respiratory rate combined to meet the preset minute ventilation
20 ICU patients showing air entrapment, Dynamic Hyperinflation and patient-ventilator dyssynchrony were enrolled between january 2014 and March 2015
Data was collected 48 hours after switching to ASV, which was applied with the same protocol
