Description of intervention(s) / exposure
Treatment: Devices - Nexus Flow Generator
Treatment: Devices - VPAP Flow Generator 25

Experimental: Nexus Flow Generator - Participants were randomised to Nexus Flow Generator group for one night.

Active comparator: VPAP Flow Generator 25 - Participants were randomised to VPAP Flow Generator 25 group for one night.


Treatment: Devices: Nexus Flow Generator
The modified device to be assessed in this study will act in a similar way to the existing device, VPAP Auto, but utilises an improved algorithm which should maintain or enhance the effectiveness of the treatment.
