Choking w/full-face
#1
I have no issues w/comfort,claustorphobia or falling asleep w/mask. However, on 3 occasions I have woke up from a deep sleep with a gasping feeling of not getting air. The machine reports are all good. I have reduced apnea episodes from over 40 to 7 and once 5.
I have seen this problem reported with nasal masks with the issue being that air was leaking from mouth and the fix being either a chin strap or a full face mask. (my mask is full face with no leaks).
Has anyone reading this had similar experiences with cpap. Also, I require high pressure as prescribed. Machine ramps up to 13 and peaks at 20.
Thank You for your response.

Welcome

I only had that happen once and it was because I was running about 5-6cm pressure so I really wasn't getting any air.
I really don't think your mask is at fault unless you are leaking a lot while you sleep.

In your case, I think the only way you can run down this problem is by collecting data each night by using SleepyHead software.
I am not sure at this time if the Respironics DS560HS is compatible with that software

My only other suspicion is the humidity.
Is your mouth/throat really dry when you wake up like this?

Hang in there and I'm sure more folks will chime in on the problem, you came to the right place!

If your machine is peaking at 20 perhaps it has reached it max but needs to go higher. Since it is unable to go above 20, maybe you are being awakened by an apnea.

Bi-level models can usually go as high as 25 cmH2O, and maybe you need one of those.

However, the amount of pressure we need is strongly influenced by sleep position. Sleeping on the back usually requires higher pressure than sleeping on our side. So, to minimize how much pressure you need, avoid sleeping on your back.

I wear a teeshirt with tennis ball in pocket sewn between the shoulder blades, to keep me off my back while sleeping.

I agree with suggestion to use SleepyHead to look at your plots of pressure versus time, to see if you are awakening when your pressure is max'ed out.

I think SleepyHead works with your machine as long as the special SleepHead patch is installed for use with '60 series machines. I don't know the details but I think there is a thread which discusses how to install the SH software and how to install the SH patch to make it work with your 560 machine.

Take care,

The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.

How do you KNOW you have no leaks?
Do you have Sleepyhead? If so, what does it report as Minimum, Maximum, Median and 95% leak rates?

Thanks for all the advice and ideas. Dry mouth, machine maxed out, and side-sleeping all make sense to me.
I posted, hoping to get common-sense ideas that I can discuss with my Dr. and supplier and your comments
are sure to be helpful.
Thanks Again

Thank You for your response.

If that happens again, try to contain your panic and investigate. If possible, don't take off the mask, but take it off if you must, and get a good breath or two, then put it back on. Do not turn the machine off.

Consciously breathe in and out and feel the air. Is there air coming in and going out easily? How does the pressure feel? Get a light and check the pressure displayed on the unit. Feel for airflow in the stream of air coming out the exhaust vent. Lift up the edge of the mask and feel air gush out to be sure it's working.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.

I found that if you insert your fingers under the bottom edge of the seal and lift it off for a few seconds you can get plenty of ambeint room air in and that is an immediate panic stopper.
