Resmed 11, Awakened by forceful air. MyAir shows 20/20 seal. I shouldn't be awakened by C-pap machine. My AHI average is 2.44 My doctor ordered 5-15... is that the pressure?

What pressure is the A11 set at? Min? Max? What is the AHI score you are getting? It would seem that you should see your sleep clinic to have the maximum pressure reduced until you become used to the pressure.

Pressure with a 5 minimum and 15 maximum is fairly standard. The 5 cm minimum might be a bit low for comfortable breathing while going to sleep though. It is hard to tell if the 15 maximum is too high or not. Your AHI is within the normal treatment range of <5.0.

Sometimes it is best to start with a maximum pressure that is lower than ideal until you get used to the pressure. Also on the A11 machine you can set the exhale pressure relief (EPR) to automatically reduce the pressure on exhale to make breathing easier. The reduction can be set from none to 3 cm. Starting out with 3 cm of EPR may be helpful in adjusting to the pressure.

To find out what is really going on during the night you can download a freeware program called OSCAR. It needs a Mac or PC with a SD card reader to use it. But it can tell you minute to minute during the night what the pressure is, and when you are having apnea events. It is really helpful in determining whether or not your machine is well set up for you or not. If you download it and can post the Daily report screen I can give you my thoughts on whether or not there is a potential for improvement. Your machine should have a SD card in it on the left side behind a flexible flap. If not you would have to get one. The one ResMed supplies with each machine is 4 GB.

How do you set the EPR?

My machine did not come with a SD card but I can certainly get one.

I can also get an SD card for my laptop and download Oscar. How does Oscar record my sleep?

Thanks for your help and suggestions.

The force of the air that wakes me up... is it addressing an apnea event... I don't think very well since all it manages to do is blow multiple leaks in my mask and wakes me up... If it was lower pressure would I stay asleep???

I'll discuss it with my C-pap customer service where I got my machine. They haven't been too knowledgeable with other questions though.

I usually figure things out. I ran many machine as a Med Lab Tech some years ago.

Anyway, again, thanks!

I just learned how to get into the clinical settings.

I'm going make adjustments as needed to get more comfortable.

The EPR was set at 3??? I just left it there.

Depending on how your machine has been set up, you may or may not have the ability to set your EPR from the user menu. You may have to go into the Clinical menu to do it. On the A11 my understanding is that you can do that by simply holding two fingers on the menu screen for 4 seconds or so. Here is a link to the Clinical Manual for the A11. It will explain the details and the options you have.

My wife has an AirSense 10 For Her and uses pressure up in the 15 cm range. Here is an example of what the Daily report screen looks like for her.

Her Min-Max is now 13.6-14.4 cm. It has been adjusted many times over the 6 years or so she has been on the CPAP. There is some advantage in adjusting up the minimum pressure as it actually prevents events from happening. When you have a low minimum pressure the events have to happen first and then the machine responds. And then after it responds with more pressure it slowly ramps down again until another event occurs. Her EPR is 2 cm and is set to full time. As a start I would suggest an EPR of 3 cm and full time as well.

If you look at the graph detail you will see that in this example she only had 1 OA (obstructive apnea) event and you can see the pressure respond up. This is because her minimum pressure is high enough that she does not have many OA events. The main factor that increases her pressure now is flow limitation and snore. A higher maximum would likely eliminate those too, but she has tried and dislike more pressure. So the current limit of 14.4 cm has been set based on her tolerance for more pressure. Since she got this For Her machine her average AHI has been 0.45 and there seems to be no reason to push the pressure higher when she finds it uncomfortable.

If you have any questions about OSCAR or the Daily report just ask. I find this daily report pulls the curtain back on what is actually happening during the night.

Yes, leaving the EPR at 3 cm is fine for now. What you really need to do is collect some data and look at it with OSCAR. The first step would be to determine what is causing your pressure to go up.
