Variable AHI

[53drew]

Hi. I've been on CPAP for 18 months. My AHI was 18 prior to treatment. Until recently, my ahi was well controlled below 5. For the past 3 month it varies from 2 - 15. I tried raising the pressure to 12cm after discussion with sleep clinic, who do not seem very interested, but it has not stabilised. Mask fit is 100% most of the time. Duration of use does not seem related, scores vary whether I use it for 4 or 7 hours. Also seems unrelated to alcohol use and there's no change in my medication or body weight. I see some post's refer to data I do not seem to have access to, such as mapping of apnoea events throughout the night.I would welcome any suggestions.

Please read the above.

It would really be helpful if we had more information.
The category of events is critical to being able to offer any ideas as to what might be going on with things.

Thanks for input. I have a Philips Dream station. 12cm pressure, fixed and variable tried. I've read your post but I'm not sure what extra data you think I should add. Grateful for help. Drew

A typical good and bad AHI detailed report showing AHI break down into each event category would be a good starting point.
Assuming you have an OSCAR compatible cpap machine.
If you don't...starting with what you are using (brand and model) is a starting point.

I found that my machine has an SD card, so can I use that with the OSCAR download?

Assuming an OSCAR compatible machine and a full data machine....yes. They aren't all compatible and they aren't all full data.
