Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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 triggering, early cycling, late cycling and prolonged cycling. | — |
