False flags

Last night I had an ahi of 1.1. Looking at the days I can see three are a couple of flags for oas that are not. There are definitely 2 and maybe a third. There was a cough and a belch that was flagged. I'm curious how often this happens

nobody ever said anything was 100% accurate. not like there's a competition or anything for the lowest AHI...

wait, there's not one, is there?

Can you cough or belch for more than 10 seconds? That's how long it takes to determine that "lack of breath" is an apnea.

You may not belch or cough that long but I could see it disrupting the breathe pattern that long. It's not easy to belch against 16.4 pressure

These machines don't care about what we might be doing or not doing...they just measure air flow and report accordingly.
It's not and can't be, an exact science due to the limitations inherent in the technology. For total 100% accuracy we need to be wired up for pretty much a sleep study to measure sleep and respiration and have someone watch us real closely and listen for belching and farting or whatever. Not something I want to do just so someone can say the machine reported something that wasn't real because I farted real big.
That's why I don't worry about random event flags that don't maybe look like they should have a flag...the machine thinks it needed a flag for a reason. Now the reason might mean something other than an apnea event that would maybe not get flagged if manual scoring in a sleep lab setting was being done..but the machine doesn't have all the additional information to maybe decide it really didn't warrant a flag.

yes, there is, and I am leading with "0.0" for 13 days out of the last 14.

disrupted breathing pattern does not an event make, only no breathing, or reduced breathing counts as an apnea or hypo.... maybe it's score a snore or something at you though.
