First SleepyHead graphs

First SleepyHead graphs
   
Hello all,

Please tell me if (1) the essential ones are shown and (2) any suggestions for
getting the less important ones removed. Screen is 1680 X 1050.

Oh, and how's my sleep? [Image: cool.gif] AHI is higher than usual and Cheyne-Stokes was
a surprise.

Thanks much,

Harv

RE: First SleepyHead graphs
Looks like you have everything we normally want to see, and you could even vertically expand some, especially flow rate. We really don't need the mask pressure, resp rate and tidal volume on most charts. The results show that with a minimum pressure of 8.0 and maximum 18 and EPR 1, your median pressure is nearly 10.0 and things don't change much from there with a 95% pressure of less than 11.0. Flow limit is the main driver of pressure, and is marginally on the high side. CA events at the end of the night look like arousal and sleep-wake events. If you were not sleeping soundly in this time, you can probably disregard that. Tidal volume is pretty low, and I think it may be worth taking a look at some random 3-minute zooms of the flow rate to see why that might be.

My inclination from this one example is to raise minimum pressure to 9.0 and increase EPR to 2. Normally we are not keen to increase EPR where centrals are the predominate event, but the fact they are near the end of the night and clear until then, make me think you are better off addressing the flow limitation.

Thanks, Sleeprider.
Is there a way to remove the unneeded graphs?

I can look through the month's data to see if there are any similar
patterns or values. Will also zoom in on flow rate.

RE: First SleepyHead graphs
Just stretch the vertical size of the graphs you want, and the others will move down out of the screenshot. The control to vertically stretch is the line right under the time. The cursor will change to a double line with up and down arrows. Also, in Oscar we can go to File/Preferences/Appearance and set the graph height in pixels. I think you have that in Sleepyhead. Just increase the size and all graphs will increase in vertical size.

Have set min. pressure and EPR as you suggest. Tonight may show changes.

Attached a chart with part of flow rate zoomed. Is this what you wanted?

RE: First SleepyHead graphs
Well, the CA events kind of look like a classic CSR pattern which is not particularly good. It means this is not obstructive. If we can zoom in closer during a period earlier in the night without these events, that would be a useful comparison. I want to zoom in to where the individual respiratory wave is visible like 3-minutes.

Let's get a look at the ERP 2 trial and see what happens.

I put that in the comments some years ago as a tongue in cheek response to being referred to a "forum guru". I doubt I am anyone's guru Grasshopper, but my trial and error problem solving approach is still working well after all these years.

RE: First SleepyHead graphs
Here's last night. You can ignore the large leak mess at 09:59. Took the mask off before
getting up, didn't turn machine off. It's supposedly "cooling down" but it's already cool.

That probably threw the max.respiration rate off too.

Not sure what to show. Here are the 3 events.
