Night 6
Night 6 was neither a big disaster nor a big success. A lot of this is that I went to bed early on Night 6 because I'd got only about 4.5-5 hours of sleep the last two nights. And going to bed early for me (as in at 11:00 pm) is always problematic for me. What tends to happen when I go to be early even when I'm really sleepy is that I'll typically sleep pretty well for the first part of the night, and then I wind up having trouble staying asleep---and getting back to sleep after the wakes--during the second part of the night. And that was true on Night 6 and I can't blame that on the AirCurve since this is a very old pattern in my sleep. In other words, given when I went to bed, I think I would have had the same not very good night if I had been using the DreamStation instead of the AirCurve.
Here's the data:
This is still from SleepyHead because Oscar is still not displaying the sessions correctly. In particular, Oscar shows four sessions (which is better than 1, like on the other nights), but Oscar's 2nd and 3rd sessions combine 2 or 3 individual sessions together.
I woke up at least 6 times. I remember at least 3 or 4 of those wakes. Two of them, I actually got out of bed to go to the bathroom, which is unusual for me and to get a drink of water. I also woke up with a dry nose and even checked to make sure the humidifier was not out of water (it wasn't.)
But I don't think any of that restlessness is directly due to the machine---as I said earlier, when I go to bed because I'm exhausted, I often don't sleep very well.
The AirCurve recorded some snoring during a 21 minute long session that starts at 2:15 and ends at 2:36. While I don't remember any snoring, it sure looks to me like I must have woken myself up with the snoring. And I remember the 2:36 wake because that's the one I went to the bathroom and also got myself a drink of water because my nose felt dry.
After I came back to bed, I also had another short period of sleep between roughly 2:46 and 3:12 (with a probable very short wake/arousal at 3:04.). These short 30 minute sleep periods with wakes between them do play havoc with how I tend to feel and function the next day. I feel much better during the daytime when all of the xPAP sessions are at least about 90 minutes long---i.e. if I only wake up at the end of full sleep cycles.
While the FitBit shows that I got some actual sleep after the 6:10-6:20 wake, it didn't feel that way. Or more correctly, I remember waking up and tossing and turning for a bit before I got up at 7:40. That's an early wake-up time for me, but since the time has just changed, it's not excessively early.
The aerophagia was noticeable this morning, but not painful. Still to be honest, it was a bit more noticeable that I usually have with the DreamStation. Because of the snoring there are also some periods where the pressure is maxed out at 9/5. So it's no surprise that the 90% pressures are 8.9/4.9. But the fact that the
median pressures are only 8.32/4.32 is probably why the aerophagia was not painful. (On the DreamStation, my median EPAP is always 4.0, and the aerophagia starts raising its ugly head when the 90% EPAP is close to 5; if the snoring gets bad when I'm using the DreamStation, my EPAP can get as high as 6, but that does not happen hardly at all because the DreamStation can increase the IPAP to 9 without dragging the EPAP up with it..)
The data hounds will notice there's one cluster of events shortly after 1:00AM. Zooming in, that cluster looks like this:
That looks to me like this is all post-arousal SWJ. The Fitbit also says I had a brief wake right around 1:04:30, just as this cluster of OAs is starting.
The OA at 1:12:30, however, probably did occur shortly after I got back to sleep around 1:08 or 1:09. Here's what that one looks like:
The breathing before this OA is nice and regular and looks like sleep breathing. You can also see the recovery breaths that follow this OA.
Here is the score card through Night 6:
Aerophagia: 3 nights worse than usual compared to the DreamStation; 3 night about the same (or better) as the DreamStation
Wakes & Arousals: 3 nights worse than usual compared to the DreamStation; 3 night about the same (or better) as the DreamStation
Feeling on Wake: 2 nights worse than usual compared to the DreamStation; 4 nights about the same (or better) as the DreamStation
