Here's a zoom. And now I'm showing CSR! This just keeps getting better and better.
I’ll work on that this evening.
You have centrals, Sierra. I see mine ranging from 11 seconds up to 40. 40 seems terribly long. Is that at all typical of centrals?
Thanks for the information about the spam filter and the machine advice.
I’ll ask about EPR adjustments tomorrow with the respiratory therapist.
I am a bit concerned about the positional nature of the centrals. I’ve read where it’s often about Cheyne Stokes respiration, heart failure or possibly some sort of brain stem problem. While I need to get these centrals minimized as much as possible, I’m thinking it might be equally important to try and determine the cause. It just seems odd that positional centrals would be idiopathic.
I'm not sure if these are even loading correctly as I can't see them when I sign off. Anyway, my AHI seems ok at 2.17. The time in apnea might be an issue at 4+ minutes. There are leak issues with the mask it seems, though they don't seem to be impacting my AHI. In contrast to my in lab sleep study, it seems like the apap is removing most all of the hypopneas and leaving me with the centrals, which I guess is to be expected. Any thoughts?
So I tried to take a nap, lying supine, yesterday evening and had a flurry of centrals and never was able to fall asleep. Last night I chose to make every effort to stay on my side or stomach and it was a very different story. Here are some screenshots to look at. So far, it seems the machine is wiping out the hypopneas I had in my PSG, with very little pressure, and that my centrals are truly positional. I now know what is causing me to wake up feeling slightly anxious and to have a bit of trouble falling back to sleep...central apneas.
I posted some screen grabs but they aren’t appearing. Perhaps they need to be approved by a moderator first?
Some of this is sleep transition I'm reasonably certain. I never really fell asleep again after around 4AM as I recall. I really wasn't expecting that I'd have worse apnea at home.
What screen should I be sharing with you to get some insight?
It turned out I wasn’t as close to my max out of pocket as I thought, so I took the docs offer to go with an APAP. Last night was the first night. I wore the mask for about 6.5 hours and had an AHI of 6.3, 6.0 being centrals. However, I was probably only asleep for around 3 hours in total so that score isn’t an accurate representation. I did find myself with some sleep onset apnea a few times last night so I presume some of the score is from that. I copied the files from the SD card to my pc but haven’t had any luck getting sleephead to load them. At this point I’m reluctant to even use the machine again tonight but I’ll want to see what the respiratory therapist at DME says when i get a call back.
Any suggestions on getting sleephead to take my data? Machine is a ResMed APAP 10.
