Could these be RERAs?

It would be interesting to see if that pattern of flattening corresponds with your other RERAs

I see the flattening. When i get home from work, I can look at the other events and expand the scale to look for the flattening.

I guess what I still don't understand is how the machine detects an arousal. How does it know if you are awake or asleep? maybe from the breathing rate?

Sure it is possible I changed position. No way to know for sure though.

I think SleepyHead tends to mark RERA events several breaths prior to when the RERA actually ends with recovery breaths. The machine interprets the recovery breaths as indicating an arousal.

Unless the criteria for scoring an hypopnea are also met, a RERA is scored when the machine sees a period of at least 10 seconds with "flattening" occurring during inhalation (the positive portion of the Flow waveform starts normally but tends to reach a premature low peak and suddenly decrease slightly and, during the remainder of the inhalation, level off or gradually decrease) followed by suddenly larger recovery breaths.
