You didn't indicate whether or not your S9 was an autoset. If it is...it may be set with 15 as the max pressure and your average for the night or 95% was 12.5. If your machine was set at a fixed 15...it would be 15 for the entire night. Download Sleepyhead and display some charts.scrollinggrandpa wrote:Thanks Grayghost4 for the info and photo. This morning I looked on the screen showing the stastics and even though my machine is set for a pressure of 15 I only used 12.5 overnight and my AHI was 0.9. I am quite happy with these results.

Re: Plastic and Ball Pressure Checker
When it comes to the numbers on the LCD screen each morning for pressure (or leak for that matter) you need to understand what it is reporting.scrollinggrandpa wrote:This morning I looked on the screen showing the stastics and even though my machine is set for a pressure of 15 I only used 12.5 overnight and my AHI was 0.9.

When in apap/auto adjusting mode (which it sounds like you are) the on screen pressure number is what we call a 95% number and all that means is for 95% of the time you were at OR BELOW that number. 5 % of the time you were above it and how much above it you would need to use the available software to see where it went to. The "or below" part of the definition is real important...95% numbers are NOT an overall average or where you were at for 95% of the night.
Don't know about the available software? See this page.

Re: Plastic and Ball Pressure Checker
Again, thanks for the inputs. As long as my AHI stays at 2 or below I am not going to worry much. I will download the data from the card about once a week just to get a better idea of what is actually going on. I have noticed that since my last sleep study a few weeks ago and changing the pressure from 11 to 15 I have been sleeping better.
