Sudden increase in central apneas
#1
Question 
Sudden increase in central apneas
Hi! I've been using my APAP for the past 3 months and haven't really had any issues until this past week. I change my N20 cushion roughly every month and keep everything clean overall, with the exception of thinking that maybe something happened to my hose when I was cleaning it this past Sunday. I heard a crack when I was swinging it a bit to get water out but I haven't felt any leakage running my hand over the hose with the mask fit function, but I'm suspecting that it might be cracked somewhere and I have my replacement hose ready.

I don't usually have this many centrals in one night but I'm wondering if these are sigh-related or positional? I read another member's post regarding this but wanted some input. My pressure range is set from 7-13 cmH2O and I average around 8-10 cmH2O on a usual night, with an average AHI of 0.3. I was finally over the jaw clenching and having head/neck/back pain but it's come back this past week and I'm desperate for it to go away! Thank you!

RE: Sudden increase in central apneas
To begin with centrals are very inconsistent where one day you have some and another day you don't have many.   Also, we all have some centrals, that just means we have paused breathing or we are holding our breath.  Maybe you are turning over in bed or pulling up your blanket.  Next remember the event is not recorded if it is not at least 10 seconds in length, so if it were 9 seconds it would not be marked as a central, it would be counted probably as a flow limit.  You have less than one an hour so it is not really a big deal.
