When we don't sleep well often the machine flags awake/semi awake breathing irregularities as flagged events. Not much we can do about them except shrug our shoulders and move on. It's common though. We all will have some of these from time to time for any number of reasons. This is why one of the first questions we ask someone who says that they have a "high" AHI and want to know if they need to change the pressures. First thing to do is determine if there was good quality sleep...if there wasn't then we have to assume that there's a good chance that some awake/semi awake events got flagged. The machine can't determine sleep status. It just monitors breathing and it can and will flag awake/semi awake breathing irregularities as some sort of apnea event. It's just a limitation of the machine that we live with. Sometimes we can spot those awake/semi awake times by looking at the flow rate but I don't often do much of that. It doesn't change anything and sometimes hard to spot even for experienced flow rate viewers.
Not something I suggest that newbies start looking at .
If I don't sleep well for whatever reason...I usually expect to see some reflection of it on my reports. Often in a higher CA (central) count and I know that the likelihood of them being "real" is very minimal because I often have nights with no CAs at all.
Hold your breath for 15 seconds...that's a clear (open) airway cessation of breathing and the machine would likely flag it but it wouldn't be the type of "central" that would be worrisome because we did it on purpose. Awake/semi awake breathing is much more irregular and likely to contain pauses in respiration just like when you hold your breath.
Also with lots of wake ups there comes the greater chance of having lots of sleep onsets when you fall back asleep and sleep onset "real" centrals are fairly common and not normally considered a problem unless they are creating a problem with oxygen levels or repeatedly bouncing a person out of sleep so that they never really get into good sleep.
Sheriff.....I am going to come visit you..I have good hearing.
OP's median leak is 0.0....that means for the majority of the time his leaks were minimal to none...the worst it ever got to was less than 10.0 anyway....that 95% leak number...easily skewed by a brief reseating of the mask or other brief leak. Too easily skewed to get upset over.
Little leaks wake YOU up..I know that and for that reason I will give you a pass on pushing that 0.0 leak number you want to see but little leaks aren't a big deal unless they wake a person up. I think it puts undue stress on a newbie to tell them that the "ideal" is 0.0 leak across the board. They might start worrying about something and fiddling with the mask and stuff...all creating more of a problem than 10 minutes at 10 L/min leak would cause....just saying......
I may have to RISE but I refuse to SHINE.
