My father has a Respironics PR System One BiPAP Auto with Bi-Flex from 2013.
The doctors says his apnea has to be treated better, because it's getting worse day by day, his average AHI is currently 30-40.
They say his general health is affected very badly because of this. He is currently 66 years old, have a stage 5 kidney desease, and diabetes. He had several strokes too. I can imagine how bad is this severe sleep apnea for his health.
He has a fixed 14-24 Bi-level setting now.
Last month we were at the doctor, and he suspected a mouthbreathing problem (which we confirmed as we saw and heard it everyday), and he got a full face mask (comfort gel blue) for testing for three weeks.
When we went back to the doctor, they thought this is not helped at all, so he got an appointment for polygraph examination for 9th aug. As I understand, they try to find out if it's CSA or OSA.
I couldn't wait for a whole month doing nothing, so as every geek like me woud do, I downloaded the data from the SD card, installed OSCAR and I started to examine the data back until 2013.
My findings so far:
- I dont know how they calculate the average AHI, but it seems like its more like 50 in average than 30-40.
- His AHI jumped up when he (probably) had a brain stroke in the end of this january. He was in the hospital for a week, but the doctors are not sure about the stroke.
- I also see a quite clear jump when they switched from Auto Bi-Level to Fixed Bi-Level mode. I don't know if it was a great decision back then.
- When he used the full face mask a few weeks ago, his AHI is fallen to a relatively good interval (like 15-25 ) but the Large Leak numbers got worse. Also this is the same week he got thiogamma and trental treatment for his kidney desase and neuropathy. I'm not sure if it's related.
- Do you think we should get back the full face mask? Is it possible that it helped that much?
- As I understand, if he has CSA, he will probably get an autoservo machine. Is this new mask will be good for that machine too?
I'm attaching the graphs, too.
