Here's what your data looks like:
You asked what was noteworthy.
Well, the first thing is your AHI is a bit higher than we'd like to see. However, part of that is the large number of hypopneas that are scored in clusters, and some of those clusters just might be sleep-wake-junk (SWJ)
breathing.
In particular, the cluster of about 7 events scored around 1:20AM. You turn the machine off right after this cluster happens and is a noticeable change in
breathing around 0:50AM. So it begs the question: Were you semi-awake during that half-hour, drifting between wake and light sleep? If so, those events are not likely real, but the 30 minute SWJ period might be a significant factor if you though you got a lousy night's sleep when you got up in the morning.
Likewise, the clusters scored around 4:50 and 5:05 look to me like they are likely SWJ caused by you drifting between wake and light sleep while you were deciding on whether to just get up or whether you should try to get some more sleep.
In general, I'd say that most (if not all) of the parts of the night that are flagged as "
variable breathing" all look like they are probably periods of SWJ
breathing. And since "
variable breathing" makes up about 1/3 of the night, it begs the questions: How much time do you think you spend tossing and turning and not really "sleeping" during the night? How restless do you think you were during this night? And have you ever had problems with insomnia?
The other thing I want to point out is that your leak line is actually pretty good: You are using a PR machine, and the top leak line is your
total leak rate which includes the intentional leak rate for your mask. The bottom line is a good approximation of your
excess leak rate. The excess leak rate is usually right at 0 L/min and its largest bumps are a mere 10 L/min and those bumps are all pretty short-lived. What this means is that if leaks are not disturbing your sleep, you don't need to worry about fixing them. But because there is evidence that you may have had a very restless night, it's important to ask: Do you think leaks are waking you up and bothering you by making it difficult to get back to sleep? Because any leak, no matter how small, that causes you to spend significant amounts of time waking up and fiddling with the mask, can create enough disruption to your sleep to make you feel less than good the next morning.
