Hey robysue, I did have a study but it was 6 years ago (and 30lbs ago). I didn't have another this year b/c I couldn't meet my deductible, so my doctor got me the auto cpap. He's working off of 6 year old data. In lieu of a new study, I think I'll be stuck going a few days and contacting my doctor for him to up the pressure.robysue wrote:The leaky mask is to blame for only some of this ugliness. Your leaks are excessively high for an excessively long period of time. The data when large leaks are detected could be even worse than it looks here because the machine can lose track of your breathing.sleepyowl wrote:Again, this is only one night with all new stuff, and I'd like to confirm that the mask leak was to blame. Any help/insights would be greatly appreciated.
But there's a whole lot of ugliness that can't be blamed on the large leaks. In particular, that cluster of events between 5:15 and 6:00 can't be blamed on a leaky mask. The clusters that happen between 7:40 and 8:15 (between the large leaks) and the clusters that happen after 8:30 also cannot be blamed on a leaky mask.
Now as palerider and others have commented, your machine is limited with a max pressure of 11cm. And the machine zoomed right up to 11cm at the beginning of the night and sat there except for the pressure decreases when the machine was trying to "fix" the large leaks.
Question: Did you have a titration study? If so, what was the recommended pressure setting? If not, why did the doc decide to tell the RT to set the machine up in Auto mode with a pressure range of 4-11cm?
Next Question: How long were you awake before falling asleep at the beginning of the night? How long were you lying in bed awake before deciding to get up this morning?
Final Question: What was your AHI on your diagnostic test?
We need that kind of information to tease out exactly what might be happening here.
I was awake for maybe 10 minutes. I went right to sleep.
Unfortunately, I don't have the AHI from 6 years ago. Sorry.
Also - there was a period around 5am when my wife woke me up due to a massive leak. I also went to the restroom and fell right back asleep.
