95% seems high

[Deweym]

I have attached last night's screen shot. It shows that my pressure was at 10 for 95% of the time. Yet when I look at the pressure chart it doesn't look like 95%.
Am I missing something?

[TonyJ]

It means 95% or LESS of the time not just 95%. If you want to see how much time you spent at a certain pressure look at the time at pressure graph.

[Gideon]

95% means that 95% of your pressure recordings were at 10 or less. It is a statistical definition.

Watch your flow limits as they are driving your pressure. So my question to you is How do you feel? Please provide a critical evaluation.

Another question. I have min pressure at 7 and max pressure at 10 with EPR at 3.
In the statistics section why does min pressure show as 3.72 and Min EPAP show as 3.70?
Note this is the new Resmed AS 11.

Quite possibly, the Resmed reported a pressure prior to coming up to full speed.

I've been seeing this with my AS 11 also.  With a min pressure at 9, there is often 1-2 seconds at the beginning of the session that starts well below 9.  While sometimes the first reading is right at 9, often it starts at ~7 and then comes up to 9 over 1-2 seconds.  It sometimes also starts at 0, getting up to 9 in about 2 seconds.

So as Nape said, I think it is just a matter of the AS11 starting to record pressure data before the blower has fully come up to speed.

If you zoom to just the first fifteen seconds on the left side of the pressure chart, you can see when it reaches your minimum set pressure. Please report that time back here. We have been adjusting the delay time; at one point it was 40 seconds, then it was zero seconds; now it is 10 seconds. I thought that would be enough time...

Here's the start of a session where min pressure was set at 10, but min was reported as 8.30:
   

Here's one where the min pressure was set at 10, but min reported as 8.12:
   

Do those help?  I can provide more examples, or formatted differently as needed -- just let me know what you need.
