central apnea question - singergal67 - 06-03-2023

would a mouth leak using nasal pillows cause the machine to falsely cause the machine to identify an obstructive apnea as a central? When I'm on my back, I get a lot of so called central events that wake me up so frequently that I sometimes don't realize I've even fallen asleep and the CPAP isn't helping in that position. I can't figure out how to attach the Oscar report, when I tried to print as pdf and attach it it didn't work.

If this doesn't work, let us know.

I think I figured out to attach the oscar

Here is the (hopefully) acceptable corrections on the screen shot. All the apneas were at the end of the night when I was on my back

RE: central apnea question - Crimson Nape - 06-03-2023

My initial thoughts are, your CPAP is set wide open. This can lead to arousals due to the vast pressure changes. Turn your ramp off, then set your minimum pressure to 7 cm, and your maximum to 8 cm. This will help with your comfort. While you may have been on your back, CAs usually occur like this when you aren't really asleep. You might also not have been fully awake, either. It is referred to as Sleep-Wake-Junk, or "SWJ" for the short version.

Your flow limit is a little high, but since you exhibited CAs at the end, I would hold off changing the EPR at this time.

Take'r for a snooze and let us know.

Turning off the ramp setting definitely helped me get to sleep faster.  My machine seems to be completely set on auto titration for the pressure and there wasn't any screen where I could adjust the minimum and maximum pressure. I think some settings can be done by the clinician that can't be done by the user and I'm due for a follow up exam so if I keep having problems I'll ask my sleep doctor about that.  I seem to sleep great for a few hours and then have trouble later in the night. I'm glad to learn about the sleep wake junk because I really did think I was awake during the part of the graph with all the apneas but when I saw the graph I thought I must have been at least partially asleep in order for the machine to be detecting apnea.

You have to enter the clinician menu to change the pressure. You can obtain a Clinician's manual in section 3 of this link:

Most members here have taken control of their therapy and perform parameter changes to achieve the best therapy for themselves. It seems that most doctors are not educated to the extent of the finer details and rely solely on the patient's AHI, hours used, and nothing else.

To add to CN's reply, this is how to enter the settings menu for your machine https://www.apneaboard.com/resmed-airsense-11-setup-info
I think you would benefit from setting minimum pressure to 6.0 and backing off the EPR setting to 2.

RE: central apnea question - singergal67 - 06-05-2023

Thanks for the info. I'll try to adjust the settings and see if it helps. I wish I had found this board 2 months ago when I first got my machine.
