ResMed 11 autosets to too high pressure - cprstn54 - 06-13-2024
I have initial=4 cm, range=5-17 cm, ramp=5 mins, EPR=auto(3). Normally, the pressure settles in at 11.5.
Often, I wake up after a few hours and it is very hard to exhale. Inhale is OK. My O2Ring low-O2 alarm (under 87.5%) starts going off as I struggle to breathe.
I have to turn the ResMed off for a minute or so and start the cycle over in order to get back to normal breathing.
I would like to avoid this condition. Any suggestions as to what is going on and how to fix?

Step 1 post OSCAR charts
Step 2 most likely pressure needs to be changed, we can tell you specifically after step 1
It appears already your settings are too low and work against each other.
Starting at 5, EPR 3 is void until pressure gets to 7. Adults typically start at Min pressure 7. With low pressure anyway, Ramp shouldn't be necessary.
With low oxygen levels, there's need to include that chart.
It is possible your max pressure is too high, but I'm thinking your low numbers are allowing events to be untreated which causes a requirement to increase pressure. So if your therapy starts higher, you'll not force the increases to pressure.
All speculation until there's OSCAR charts.

We will be much better able to help you if you provide more data. Download Oscar, a free apnea reporting program that will allow you to post a chart for each night's sleep.
Right now I see that your beginning pressure is set too low. Most adults are pretty air-starved with pressure less than 7, so I suggest that you raise your beginning pressure setting to 7. I'm guessing that the 4 you mention is for ramp. If at all possible turn ramp off. You don't get any real therapy during ramp. You need EPR set full-time at 3. Using it as you now are, you don't get any benefit from the EPR. This will make your exhalation much easier.
OOPS! I see that Dave posted as I was writing.

I exported last night's "details" to csv (attached). Is that what is needed?
RE: ResMed 11 autosets to too high pressure - SarcasticDave94 - 06-13-2024
Personally I would rather have it attached to the post. I think they're easier to view. And then we don't have to download to our devices.
No sorry, not entirely helpful. It's going into what looks like a spreadsheet look. Need to see data with charts.

The prior file is missing the oximetry. The attached version (same name) ought to show it.

How about a pdf of the daily report (attached)?

Look at the H events. The grouped H events sho positional apnea. You are sleeping in a position tha kinks your neck and blocks your airway. No pressure changes will help, you have to find a way to stay out of that position.
If you can’t easily make adjustments like keeping off your back or using a flatter pillow you may need a collar.
I have a link at the bottom of the post for a collar
