Do flow limitations typically cause oxygen desaturation?

[Michaely6]

If AHI is 0 but oxygen levels still drop in the 80's, can flow limitation be the culprit behind the decrease in blood oxygen levels?

[bonjour]

A single flow limitation, i seriously doubt it. But an extended series of flow limitations near 50% reduction, that is certainly possible. Are RERAs present?

[Michaely6]

The vauto does present rera but the flow graph doesn't have some flattening to the inspiratory curve

[bonjour]

If you would like specific responses post your charts showing what you have questions about.

Height and volume both come into play on breathform evaluation.

[Michaely6]

Ok. Will post charts when I get home thanks

I have the vauto and it does not display Rera’s.

AirCurve 10 does not show RERAs but you can identify them visually as series of diminshing flow-limited breaths followed by recovery breath, like these:

Yes you are correct, I meant it doesn’t exactly point out the rera’s but like you said looking at the flow chart you can identify them.
