Looking for interpretation of OSCAR data - CautiouslyPessimistic - 02-11-2022

Hi,

I've been using my CPAP consistently for about 2 years now and just don't feel much of an improvement.  I've played around with the min pressure at times but don't quite know what I'm looking at with the OSCAR data.  Is there anything that stands out that I should try?  The settings initially were the standard default ResMed 4-20, etc.

Thanks!

Hi CautiouslyPessimistic! - Welcome

It appears you may be chin-tucking, thus increasing your flow limit. Resmed's use the flow limit value to determine pressure changes. Because you have your CPAP set to basically wide-open, the drastic pressure change is causing arousals. I would recommend that you set your pressure range to 8 to 12 cm and run with those setting for a few days. These setting should reduce the "wind tunnel" effect. If you keep experiencing limitations, you may wish to consider trying a soft cervical collar (SCC) to limit the range of motion of your chin.

I would have done that adjustment if it were me. I know I would at least (1) increase the min pressure to 7 cm, and (2) limit the maximum to somewhere near 13 cm.
Notice that it is rare, such as 00:15 on Feb 3, when the machine goes a little bonkers, that your pressure is above 13.

I too would recommend trying 8-12 range for a while.

Thanks everyone for the insight.  I've been doing the 8-12 for the last week or so and figured I'd attach the last 3 days of data in case anything stands out.

Your numbers look great. Not included in the AHI are the flow limits and you still have some. That is about all I could suggest. 

You use EPR (exhale pressure relief) at the max of 3 but because of your min of 6 limits Epr to 2. 

Raise the min to 7 to slow the EPR to work at 3.

Hi staceyburke, the OP has already changed the minimum to 8.

CautiouslyPessimistic, do you have any sense of whether pressure changes bother you? And could you say a little more about how you are still feeling? Is it daytime sleepiness, night-time restlessness, or ....?
