Do these waveforms represent an arousal

[BigWing]

I'm wondering if these waveforms represent what the experts call 'an arousal' (or even a 'RERA')? I see this many times every night, and the key indicator of them (to me) is a spike in Pulse Rate (from my oximeter).

My breathing is fine and looks like normal sleep breathing, but then for maybe 10 seconds becomes very different....usually with slightly larger inhales and exhales but with a missing breath or two, sometimes returning to a normal sleep-breathing waveform straight away but often becoming more like awake-breathing for a while.

As you can clearly see in the image, at the same time as this sudden change to an odd pattern in Flow Rate there will usually be a brief spike in Leak Rate and in Movement (from the oximeter)....followed about 15 seconds later by a quick spike in Pulse Rate AND - sometimes - a brief blip in SpO2 (but this can go up OR down!).

I am sometimes awoken by these events, but not usually.

That is an arousal that came from some kind of movement. When we shift position we typically hold our breath or breathe shallow, then have a deeper recovery breath. You can see the big inhale, then long exhale, coupled with some movement.

We all do it during sleep, nothing to be concerned with unless it happens frequently.

Ah, thank you. So it IS an arousal but not a 'sleep apnea related arousal'. Is there a similar typical set of waveforms for the latter?

As I said, it does seem to happen quite often - maybe 1-2 times per hour.
