What are small periodic blips in SleepyHead?

no.

yes

that's complicated.

I never flatline during my centrals and these tiny pulses are always there, and always the same. Isn't too repetitive for human behavior?

doesn't it look just like a breath, just very tiny?

And they are spaced and shaped differently than my normal breaths. Could it be the machine "noise" coupling or something else?

Event length can vary greatly. They can last 10 seconds, they can last a minute. Not all events are actual events, awakening slightly can cause any number of events to show up. My centrals don't always look identical but most of them have the same pattern each time, the interval length just varies. It's more than likely you rather than the machine. I get similar patterns with a Respironics DreamStation APAP and a Resmed Autoset 10.
