- Primary Outcome Measures
Name Time Method The primary outcome of the study was an assessment of the patient-ventilator asynchrony index using NIV during sleep. The analysis of the patient - ventilator asynchrony occurred through the pressure, volume and flow curves of Trilogy ® extracted by a software (from Sleepware ® G3) of concomitant analysis with the Alice PDX ® polysomnography data. The asynchronies assessed in the present study were: ineffective effort, double<br>triggering, early cycling, late cycling and prolonged cycling.
- Secondary Outcome Measures
Name Time Method Secondary outcomes were the asynchrony index for specific types of asynchrony in the sleep phases and the index arousals.
