Attached is her sleep study. This was done with an at home kit, so it is at our current 7500 ft altitude.
We are still in search of a doctor to talk to. She was at a Pulmonary clinic getting a Pulmonary function tests (PFT) , she goes in soon for a meeting with the doctor who also does sleep study analysis. We will see if we can get him to review her results.
Do you have a recording oximeter?
That is a diagnostic sleep study with 288 minutes of Oxygen less than 88%. That is the worst O2 Sat that I have seen based on duration. I could care less about lows because they are typically spikes. These levels say supplemental oxygen is needed without CPAP.
O2 Sats while sleeping are typically lower than daytime values.
IMHO with those values you should periodically check your overnight levels to make sure they are higher.

It would be great if you could record a few nights of O2 before the doctor visit. I also hope the doctor will pursue the question of nighttime O2 sats, whether or not you have any data to present.
Don't have anything to record oximeter. We do have oximeter that goes on your finger. We would need to buy from amazon I suppose. I see some watches with finger sensor for $100-$150 .

I will set the max to 8.0, leave EPR at 1. I do see that the pressure was at 10-11 a lot, thus the Exhale pressure was 9.
Do you think that the pressure being alllowed to go higher is cause of CA's.
I can also see that running this simply as a test for results will give more information. I'm guessing that the OA's will go up a little but possibly get the CA's down.
Thanks for the quick response.
We're dealing with someone sensitive to pressure changes and higher pressure in general. We have successfully coached members to use fixed pressure to remove variables that allow us to establish a better baseline for events, reduce sleep disruption, and reduce the CA events that seem to go along with them. If I thought it might compromise her therapy, I would not suggest it. My objective is to improve comfort and to move closer to efficacy, and sometimes that means not relying on the Autoset algorithm that is very sensitive to flow limitation.

Thank you very much for the feedback. We are seeing improvements and even think we understand what is happening a little bit. Your recommendations are making sense. We are anxious to see the results tomorrow with min and max set to 8 with EPR at 1. Still have the ramp on with starting pressure of 6.
