ASV Machine Centrals at beginning of sleep cycle

17 days in, By my sleepyhead results, I noticed a pattern of CA events (15-20) within the first 30 minutes of sleep.

I am on an ASV machine. (never been on CPAP) Could this be me "fighting" the machine?
I keep hearing that ASV takes longer to get used to...

I remember seeing people saying its common to have centrals spear at the sleep wake junction.

Out of curiosity... how do you know when your falling asleep?

My guess (not being a sleep doctor, plus being somewhat new to this technology), is that your 'lizard brain' which takes over at night, simply needs more time to adapt to this new breathing technology. Anybody else care to weigh in For what it's worth Show us some Sleepyhead waveforms.

Here's the research article that notes central apneas during the transition to and from sleep are normal:

Ventilation is unstable during drowsiness before sleep onset

Thank you Johnbfisher.

It is nice to see a scientific journal with source info.
