excessive pressure?

[swampdog]

I've been using a Respironics REMStarAuto M series with ResMed Mirage Swift nasal pillow for close to 10 years--virtually no problems. Pressure range 4-20. As it is aging and making noises, we are replacing it.)

Am now trying to use a ResMed AirSense10 Autoset with ResMed AirFit P10. Pressure range 5-20. Humidifiers on both machines.

About 25-40 minutes into session, pressure starts billowing my cheeks and venting through mouth. It has never been a problem with previous machine. If i sleep through that, I am awakened by painfully dry mouth. My wife and I were awakened by my throat or back of mouth making slapping sounds as if opening and closing. If I position my mouth to prevent venting, pressure builds in my ears or esophagus.

Have tried using old pillows on new machine, and see no change.

I expected a simple transition to a new machine, but feel like this is a medieval torture device which only allows me to sleep 45 minutes to an hour between painful awakenings.

Ideas?

Thanks!

should have added that my pressure has been running 14.5 to 14.7 most of those nights that I tried to use the new machine all night.

Welcome!

Wow, what a different experience between the two machines! As I am somewhat of a newbie myself, I don't really have any advice for you. But I do believe it would help if you were able to narrow your pressure range to provide more optimal treatment. If you'd like help with that, it'll help us if you upload a screenshot of your sleep data. Many of us here use Sleepyhead.

I used to have a Resmed M-Series Auto, and am using a Resmed Auto Bilevel now, which is pretty similar to your current unit. I think the trick here is to try to determine what pressure your old M-series was delivering, and try to replicate that to start with. The Resmed is more aggressive, and it can be limited if necessary. I don't think there ia any harm in setting the Resmed to 5-11 pressure and see if this improves your experience. Don't forget you can use EPR (exhale relief pressure) settings to make exhalation easier and more comfortable. You will need to use it for a few days and then check whether this pressure is avoiding obstructive events to an acceptable level.

Be sure to download #Sleepyhead which will make it much easier to assess your results.

Hi swampdog,
WELCOME! to the forum.!
You could try setting a range of pressures such as 11 CmH2O for your minimum, and 17CmH2O for your maximum, and see how that works for you. Do hang around for more pressure suggestions, as two or more heads are better than 1.
Be sure to download the data-management software called: #sleepyhead then after a couple more posts, you can post some data so people can get a better idea as to how to help you.
Good luck as you continue your CPAP therapy and also with your new machine.
