Just got diagnosed, need some advice - tedlongford - 02-22-2022

Hello, I just got diagnosed with obstructive sleep apnea based on an at-home test. My AHI was 39.2. They have prescribed me a trail of AutoCPAP at 4-20 cmh2o. I have placed an order for an AirSense 11 but it is on backorder for god knows how long.

My brother in law has an old machine (AirCurve 10 S) that I can use in the meantime if I want.

Considering that this machine does not have an auto setting, where would be a good place to start from a pressure standpoint on the CPAP setting?

I am planning to record my data so I can analyze it with OSCAR.

Thanks,
Mike

First a Factory reset. This is to ensure all settings are on default state prior to starting.

EPAP = 4
IPAP = 7

This is equivalent to CPAP mode,
Pressure=7
EPR=3

Expect to adjust pressures after your first night, based on OSCAR data of course.

Thanks, I will start here and report back.

Here is my OSCAR screen shot. Had a rough night with it to start, but will stick with it and get more data. I also included my spO2 and pluse rate from my wellue o2 ring.

AHI was good but SpO2 was awful. I think take EPAP to 7.0 and IPAP to 10.0. Should improve SpO2 and make breathing a bit easier.

I was going to 6 and 9 but have no problem with 7 and 10.

Also the real issue with sPO2sPO2 is duration at or below x%
Your oximeter should have that data,though it's not in OSCAR. Especially the 88% and 90% durations.

Want to see how the sPO2 responds to these changes.

Thank you so much. Will try again tonight and report back!

Here is the time under 90%. I have two rings and have been wearing both. One seems to read a bit lower than the other, but the shape of the graphs is the same.

SpO2 levels under 90 are 46 minutes for one, an hour and 18 minutes for the other. There's a reasonable belief that some large percentage of this below 90% will also be at or below 88%, which is a serious enough issue. I'd suggest you report this to your doctor and begin talking about ordering an overnight oximetry test.

Thanks. I did notice that my spO2 looked a lot better the first night on the machine that it does normally, so hopefully getting the settings more dialed in will help bring my O2 up even more.
