[Diagnosis] Weirdly shaped apneas in OSCAR

[biboombap]

Hi all,

I switched to a full-face mask for the first time and these some strange tapering apneas in OSCAR. It's like the breathing gets smaller and smaller until there's a registered event. This never happened with the nasal masks.

   

Does anyone know what causes this and whether it's a concern? Thanks very much

It looks like positional apnea where you are cutting off your own airway by how you are lying. It is also called chin tucking where your chin drops to your sternum cutting off your airway.

Happens more sleeping on your back or to high a pillow. Not serious at your level of occurrence but you should try to find out how you are sleeping to stop it.
