Trial Outcomes & Findings for CPAP vs ASV for Insomnia (NCT NCT02365064)

NCT ID: NCT02365064

Last Updated: 2021-09-09

Results Overview

Change in insomnia severity from baseline to 4 months as measured by subjective questionnaire. The Insomnia Severity Index has seven questions. The seven answers are added up for a total score. Scores range from 0 - 28. A higher score indicates a more severe degree of insomnia.

Measure
Continuous Positive Airway Pressure
Continuous positive airway pressure (CPAP) intervention as active comparator. Provides a fixed pressure for both inspiration and expiration. AirCurve 10 ASV: Device is able to provide both ASV therapy and CPAP therapy modes.
Adaptive Servo-Ventilation
Adaptive servo-ventilation (ASV) positive airway pressure as experimental intervention. Provides a higher pressure for inspiration and a lower pressure for expiration with changes in the pressure support level to meet a target minute ventilation. AirCurve 10 ASV: Device is able to provide both ASV therapy and CPAP therapy modes.
