I see weird AHI numbers when I'm awake as well. Especially if I woke up and I'm trying to get back to sleep. Lay there, bored, half awake, breathing, yawning, not breathing while shifting around. It's all abnormal compared to the breathing pattern when you are asleep and they get logged as whatever anomaly the machine thinks it is seeing at the moment. I hate it if I wake up early and tell myself I can get another 45 minutes of sleep and then bag it and just get up after 20 minutes. I notice the AHI when I first woke up was like 1.x and then after 20 minutes awake before I give up, I turn off the machine and the AHI has bumped up t 3.x.
I don't remember seeing big numbers like 35 CA in my awake time. Are you saying 35 tick marks on sleepyhead during that part of the timeline or some normalized hourly number?
If you are looking at session time on the CPAP machine display for less than an hour session, those are probably scaled up to an hourly AHI rate and fragged out among the OA, CA, etc on the machine display. Remember each time you turn off the machine and turn it back on that's a new session. Short sessions of awake time could have squirrelly numbers, too.
As for raw numbers... I guess if you are awake and tired but restless for an hour, then some perceived anomaly in your breathing every two minutes of being awake may not be not out of line. If you yawned every two minutes for an hour that would be thirty right there. Shift around, roll over, back and forth a few times trying to be more comfortable and you could probably get to 35 breathing anomalies pretty easily in an hour.
Anyways, you can expect to see some anomalies in AHI if you run the machine while you are awake. How much to expect I can't say, only what I see when it happens to me.
If this is an occasional occurrence, then the doc will see that as one-off anomalies in an otherwise consistent pattern when you look at the Overview report. A few bad nights in the past sixty days of data. Impact on the Statistics report is probably pretty small, too. Let's say you sleep 7 hours per night, or 420 hours between doc appointments. If ten percent of the nights you add an hour with awake events, then that would be 6 hours of out of 426 hours. Probably negligible impact.
I could be wrong about that, but that's how I would look at it.
Don't lose any more sleep over it, it will just mess with your numbers even more
