Comparison of Auto-Adjusting Positive Airway Pressure Devices

Not Applicable

Completed

• Conditions: Obstructive Sleep Apnea

• Registration Number: NCT02357706
• Lead Sponsor: ResMed

Brief Summary

Primary Outcome Measures

Name	Time	Method
Mean Oxygen Desaturation Index (ODI)	1 night (446 minutes) for APAP A, 1 night (436 minutes) for APAP B.	Number of times that Oxygen Level Drops by 3% below baseline value, Events/hour
Mean Apnoea-Hypopnoea-Index (AHI)	1 night (446 minutes) for APAP A (AirSense), 1 night (436 minutes) for APAP B (Apex)	AHI measures the number of apnoeas + hypopnoeas per hours of night (events/hour).

Secondary Outcome Measures

Name	Time	Method
Flow Limitation (%)	1 night (446 minutes) for APAP A; 1 night (436 minutes) for APAP B	Percent of flow-limited breaths in relation to the overall breaths at night.
Obstructive Apnoea Index (OAI)	1 night (446 minutes) for APAP A; 1 night (436 minutes) for APAP B	Number of obstructive apnoeas per hour of nights sleep, Events/hour
Central Apnoea Index (CAI)	1 night (446 minutes) for APAP A; 1 night (436 minutes) for APAP B	Number of central apnoeas during hours of sleep, events/hour
Respiratory Effort Related Arousals RERAs	1 night (446 minutes) for APAP A; 1 night (436 minutes) for APAP B	Number of RERAs per hour of nights sleep, Events/hour
Mixed Apnoea Index (MAI)	1 night (446 minutes) for APAP A; 1 night (436 minutes) for APAP B	Number of obstructive and central apnoeas per hours of nights sleep, Events/hour
Mean O2 Saturation	1 night (446 minutes) for APAP A; 1 night (436 minutes) for APAP B	Mean blood oxygen Saturation, %
Hypopnoea-Index HI	1 night (446 minutes) for APAP A; 1 night (436 minutes) for APAP B	Number of Hypopnoeas per hour of nights sleep, Events/hour
