[CPAP] Help with analyzing Oscar data

[SunnyA]

Hi,

I was diagnosed with sleep apnea about two years ago after a sleep study showing an AHI of 18 per hour. I got prescribed a mouth guard which I've used ever since and it has worked alright. However, during the last couple of months my partner has told me I've gotten my apnea back, so I went to a doctor who told me to try CPAP.

I've been trying out the cpap machine during the last couple of weeks and unfortunately it doesn't really feel like it's working as good as it seems to work for others on this forum. I still feel tired after 7-8 hours of sleep and I also seem to have some issues with mask leaks during the night. I downloaded Oscar to see if I could get a better understanding on what's not working, but I really struggle to analyze the data.  

Maybe someone could help me out?

Thanks!

I put this post together a few weeks ago describing how your machine works and why it does what it does.
Your charts match the description very nicely.

EDIT: As you'll see in that link, your pressures are being driven primarily by the flow limitation spikes and snore spikes.

In terms of numbers, your data looks great. 
The only suggestion I would have is to raise the minimum pressure so that the machine starts off with pressures closer to your median value.
That way.. the pressures would not have as far to drift upwards.

Your median values for EPAP were 7.78, 8 and 9.7
You are using EPR setting of 2
So your median IPAP pressures are 2 greater at 9.78, 10 and 11.7
I got these from the statistics section on the left side

Arranging for your pressures to start out closer to the median might help the machine to get to the therapeutic levels a little quicker.
However, your AHIs are so "good" that this change may not alter much in the numbers.
Setting the min pressure to 9 or thereabouts would get you closer to the median values.

One thing I forgot to mention... you might get a better control of your flow restrictions by increasing EPR to 3.
This will increase the "pressure support" from 2 to 3.     If that causes a bunch of CAs please let us know.
