Apap Report

Please advise about my report and how to reduce my AHI.
Thanks

Your AHI is composed of 3 categories.
Clear Airway events (centrals)
Obstructive Apneas
Hyponeas.

If you look at your Clear Airway index you will see that it compromises roughly half of your AHI.
We don't treat Clear Airway events with pressure using your type of machine because the airway is already open. Hold your breath right now for about 15 seconds. That is sort of what a clear airway event is.. No air flow but the airway is open.
Obstructive apneas and Hyponeas are obstructive (airway collapsed) in nature and we do treat them with pressure.
I see lots of breaks in therapy where the machine was turned off. I assume that you are having multiple awakenings throughout the night.
If those clear airway event clusters are related to sleep onset or even being flagged while you are wake (yes, it does happen) then we can't do much about them except try to limit them by getting more consolidated sleep.
It is normal to have some centrals (clear airway events) during sleep stage transition and even when tossing and turning in bed and especially if we are awake. Our awake breathing is much more erratic than sleep breathing and the machine is easily fooled into recording false positives when in bed and tossing and turning trying to sleep.

First thing I would do is try to figure out what is causing the awakenings and the breaks an therapy to see if improvement could be made there. It needs work anyway....and then see if the clear airway indexes reduce.
The Obstructive components in your AHI (OA and Hyponea) seem to be around 4 and some of them might also be "awake" false positives.

You aren't in the US are you? Did you have a sleep study without a mask and machine and if you did...was there any mention of centrals?

With the presence of the clear airway events...and even though I think they are likely related to sleep onset or awake events being flagged.....until we evaluate possible real central apnea events it is really kind of hard to offer ideas.
For some people adding a bit more pressure actually causes and increase in the clear airway events even though it might reduce the obstructive events. We have no way to know for sure if your clear airway events are false positives (and can be ignored) or real events that might be a problem. 1 or 2 clear airway events an hour..random ..alone through the night we don't worry about. You are having clusters of them and until we know for sure that they aren't a problem, we proceed with caution.

So....how is your sleep quality? Fragmented? Having trouble sleeping? Tossing and turning?
If so...any idea why?
