Doesn't airflow fully stop twice per breath?

  Not for the AHI's purposes, no. It has to stop for a certain length of time to be counted.

    In the US at least I think this time is usually 10 seconds. https://www.cms.gov/medicare/coverage/evidence/cpap https://www.cms.gov/medicare/coverage/evidence/cpap

      Yep, mine is ~79 (at least, ten years ago it was)

  AHI only measures stops of 10 seconds or more

  Only on Hacker News would someone picture an oscillating waveform with a derivative of 0 twice per cycle! (I'm just poking fun)

    Remind me never to ask HN to check if my indicators are working.

      Yes, no, yes, no, yes, no…

      Define "working"?

        it's not a bug; it's a feature!

      There seems to be an intermittent fault.
