Share your Flow limitation graph and sleep study AHI please

[MyIdaho]

I was diagnosed in late November with Very Severe OSA and my sleep study AHI was 130 events per hour. I have responded very well to xpap therapy with a daily AHI ranging between 0.5 to 1.5 events per hour. I do feel better, sleep soundly through the night and BR breaks have dropped by 5 per night down to 1 or none. However, I do have days that I'm still tired and wondering if I'm receiving all the possible benefits from therapy. Yes, I do understand other factors can cause one to be tired... My flow limitation chart does not look very good, suggesting that their is still some limitation in flow. I was wondering if others would be willing to share their flow limitation charts and sleep study AHI's. Perhaps those of us with very high initial AHI do not have fully resolved flow limitation graphs but those will lower sleep study AHI have fully resolved flow limitations. Post your data and let's see if there is a correlation!

Here is my flow limitation graph with machine settings of: cpap mode, 17.6 cm pressure, EPR=2, 10 minute ramp from 12 cm at start up




Here is my flow limitation graph with machine settings of: apap mode, 17.6 to 10 cm pressure, EPR=2, 10 minute ramp from 12 cm at start up




Post your flow limitation graphs, I wanna see if mine are typical or really poor for successful therapy.

I finally have found someone in my serve OSA level....I'm AHI 131.1 I have all my Sleep Study and SleepHead data/charts posted in my thread here viewtopic/t87166/AHI-131--no-REM--Help- ... sults.html

Here's last nights chart....

The followings are my recent graphs with so so results:









But, about a year ago I had FL as lousy as your:

(At that time I was in CPAP mode, and used a full face mask Fisher &Paykel #231. Switching to APAP mode and changing to my current hardware made the difference)








p.s. according to a 3 years old French study, about 12% of CPAP users suffer from RES (Residual Excessive Sleepiness) in the daytime. By omitting Restless Legs and Depression the prevalence dropped to 6%.

On brief viewing it looks like you have a little bit of REM mouth leak. Things looking pretty good though
Do pressures of 13+ feel too much for you? Your machine looks like it hits 13 a lot. I wonder if 13.6-14.0 would give it some more room?

Here's what I typically see. Main reason I rarely even look at it.

Perfect :p
