Mask Pressure-why was it important to know?

[MagsterMile]

Mask pressure - what makes up mask pressure? I noticed that in the older SH version, there was a graph depicting mask pressure. In the newer version (that I downloaded late last year) I'm not seeing it anywhere in the graphs or data. Maybe I'm overlooking it.

Is mask pressure not considered important any longer? When we did get our mask pressure numbers in the past, what exactly were we looking at? I use a FFM. If someone is using nasal or pillow masks would they have gotten different information?

It never was important. Why are you worrying about this?

[Pugsy]

I never have bothered with mask pressure. It pretty much mimics the regular pressure line anyway.
I always have just turned that graph off so I can see something else that is more important without having to scroll to see it.

mask pressure is.... the measured pressure in your mask. as opposed to what the set pressure is.

it's helpful (looks at pugsy) with an adapt, because you can see where the machine is responding to events. it's also useful if you're zooming in and you an see more of how the machine is responding, and acting, you can see the FOT in the mask pressure when the machine is determining what kind of event you have (though that may not happen on an adapt.

if you're not seeing the mask pressure trace, you've got it turned off for some reason. check the list of active charts in the lower right corner of the daily screen, because it's certainly there in the the 0.9.8-1 version of sleepyhead.

ignore "therapist" (hah!)... nothing good ever comes from there.

With sleepyhead not reporting correct settings for the aircurve 10 I use it to find the settings of the vpap

I hear you but I can usually see what I need on the regular pressure line well enough to suit my needs.
Remember...it's rare that I put my data under the microscope at that level...if it is ever needed (or someone else needs it) then that's just a special graph request. I don't need it 99.9% of the time but I do need the leak graph 100% of the time.
The mask pressure graph is pretty much useless unless zoomed way in anyway.
So I still prefer to turn it off and keep my 4 basic graphs in one screen shot/image because I hate screen shots or viewing with a dozen graphs and all so small I can't evaluate them....and then if needed then I will request a special graph and zoomed in if needed.

With my ASV showing pressure for EPAP, Max IPAP, IPAP, and Min IPAP the mask pressure graph gives me a better picture at a glance.

as usual, you have good points, for high level looking, the pressure graph is probably better, and for zoomed in, the mask pressure can be better... at least, that's how I usually view it

as long as people don't put BOTH in there, i'm fairly happy either way

that certainly does get mighty busy and confusing looking, I agree.

I would expect it to be there. There is a little click box at bottom right to turn graphs on and off.

I guess it could be a bug of some sort. What exact machine model number and SH version do you have?

I've always found the mask pressure line somewhat interesting and useful in understanding things, but I guess I don't often use it to make decisions and adjustments to therapy.

Thanks for directing me to where I can look at my mask pressure. It's crazy but I feel comforted knowing I can look at it when I want to. Sometimes my mask feels like it gets tighter on my head as the night wears on. Could be the way I'm sleeping on the pillow. I had thought it might have something to do with the mask pressure itself. I'm truly not obsessing over wanting to know every nuance about my therapy. Basically I'm a curious person.

I also don't have mask pressure showing up in Sleepyhead. I thought maybe it was a Resmed thing and didn't know I was missing something. There are 2 options in Preferences on mask pressure,(one high resolution). I checked both and closed and reopened Sleepyhead but still no mask pressure wave form. I left the lower and upper set at default 0.0 but had tried an upper of 30 at one time without results. Not really concerned if I can't get it but just bugging me if it's something I'm missing in the settings.

I think only some of the respironics have a mask pressure trace.

the autoSV does.

Thanks. That's what I figured. So it seems the 760 doesn't have the mask pressure graph. I've only used it in Bilevel, so I was wondering if it would show up if in auto bipap. Might have to try that to see.

You know, sometimes I am not a clever man.

It just dawned on me that the "pressure" and IPAP/EPAP graphs are measures of the pressure the machine is trying to blow, and the "mask pressure" is based on the actual measured pressure.

I used to think that "mask" pressure meant it was an estimate of pressure at the mask, based on hose size, flow rate, mask type, air compressibility, etc., but now I'm not that sure it's not just the pressure measured at the output of the blower unit.
