New to OSCAR, need some help understanding my data

[sleepadventure]

Hello, 

I'm new to the board, but have been diagnosed with OSA and using a CPAP since 2021. My sleep consultant says my AHI is considered mild, but that I would still benefit from the CPAP device.

Generally, I find the machine has improved my quality of life somewhat. I notice this especially when I don't have my CPAP while sleeping (there have been a couple of occasions of power outages, travel - overnight - without my machine for a night, etc). However, I still often feel tired, yawning a lot and get daytime sleepiness. There could be other factors at play here, but I'd like to check that my machine settings are optimised first. Here are my settings (taken from my device):

- Machine: Resmed Airsense 10
- Mode: Autoset
- Mask: ResMed P30i nasal pillow
- Pressure Range: 4-14
- Ramp settings: Auto
- Response: Standard
- EPR: On
- EPR Type: Ramp Only
- EPR Level: 1
- Pressure relief: On
- Climate control: Auto
- Tube temp: 27'C
- SmartStart: Off
- Sleeping: I sleep on my side mostly.
- I don't use a soft cervical collar currently

I've attached last night's OSCAR daily. I followed the guidelines from the Wiki for organizing my OSCAR view. I added additional screenshots of the other charts also, if they're useful. I'd really appreciate if anyone could take a look at my data and suggest any optimisations.

I see a few things that will help.  First, turn off ramp.  You don't need it now and you get no therapy during ramp.  Also, if you wake up for a bathroom break, ramp starts again when you return to bed, robbing you of therapy.

Your beginning pressure is way too low for an adult.  Set your pressure at 7-15.  This will give better therapy and comfort.

Your flow limits are high.  They are shorter apneas and need to be lower.  Turn on EPR full-time, set at 3.  That will lower the flow limits and make your breathing easier.

Good luck!

Thank you for the advice 

I’m going to try these settings tonight. I did wonder about the ramp settings, I usually wake in the middle of the night (dog wants to be let out) and I guess ramp starts all over again, but I fall asleep much sooner - before my full pressure kicks in.

Here is my data from last night's sleep.

It looks like my AHI has increased, I'm not sure if that's just because I disabled 'Ramp' and the machine is catching more events now, or if the settings need to be adjusted again.

I didn't feel as groggy this morning, though not sure if that's placebo effect or if it was my new settings either

Hey board, sorry to bump this thread again, looking for some more advice.
I just got a Resmed Airsense 11 and using the same settings, with EPR switched to 2.

These were my results last night. I zoomed in on the flow limit chart to see if that is useful, do I have a flow limit / flat breathing issue (or maybe partially treated breathing issue?)

I am reading the wiki, other posts and YT videos to try and learn how to interpret the data myself too. But it's slow progress 
Thanks again.

Go back to EPR 3. You will be more comfortable and have lower flow limits. Flow limits are short-duration, unreported apneas, and we want to see these as low as possible.

[sleepadventure]

Ok thank you. Here's last night's results with EPR set to 3.

AHI increased, but is that good or bad? i.e.: is it catching more untreated apnoeas?

[Deborah K.]

I don't think changing your EPR setting has any effect on your AHI. Stay at your present settings and see what happens.

[sleepadventure]

Got it, thank you. Here's last night's results with EPR left at 3.

Looks like my leak rate wasn't as good as the previous night.
