Pressure relief is the drop in pressure as you exhale, to make it easier.

So, if your inhale is a pressure of 9, and your EPR is set to 2, then your exhale pressure would be 7. If set to 1, then your exhale pressure would be 8. If your EPR is set to 0, then your inhale and exhale pressures will be the same (9 in this example). For some people, this works better.

The pressure setting of 4 is the minimum pressure that the machine puts out. So, if your pressure was only 6, and you had an EPR setting of 3, it would still only go down to 4 on exhale since it can't go below 4.

I'm not sure I understand EPR settings... Unless I'm reading it wrong, according to Resmed manual with EPR "ON" (as mine is) it will not drop below a pressure of 4 regardless of setting. So am I actually getting 4 even though it's set to 1??

EPR drops the set pressure by whatever it's set to, when you're not inhaling.

Yes, it won't go below 4, but if you look at your pressure curve, you're only at 4 for a few moments at the start of the night when you're first ramping up.

I suggest you try turning the ramp feature off altogether as most of us do early on in the Cpap journey. It can cause confusion re settings (ramp's vs prescribed mins/max), plus inadequate therapy while it's 'ramping' up to the scripted min. setting. Unless your min. is very high (eg 10+) you will probably find you don't need it at all once you've got over the initial (and easily tolerated by most) little burst of air once mask is on. Getting rid of it will at least take one more variable out of things to worry about and deal with.

I was wondering how long you have been using the Resmed 10? I just started about three weeks ago. My numbers have been all over the place, but not as bad as it was during my sleep study. When I called they told me that it will take my body a while to get use to the machine and that my numbers overall are coming down.

I've had it about 2 weeks. I used a mask that came with the machine for the first week+ and it was terrible. Then I got the Philips nasal gel pillows and they are much better. Currently trying to acclimate.


Last night was a bit of a disaster again. I'll post chart and experience when I get home from work this afternoon.

Baby steps.
It can take a while to get settled in and get it right.
Even the best providers do not have the time/motivation to give the help we find here.

This forum is a blessing--and a gift.
Thank you, Johnny and Carolyn.
PS--Happy Birthday in advance, Johnny!

I can't use the sinus pillows because of all the sinus problems I have. I wish I had that option

Ok just got home. Last night was a bit terrible. My recollection is falling asleep at around 12:30am lying on my back as usual. Some time later I was awakened lying on my side and if I recall it seemed like I woke because I couldn't breathe through my nose for some reason. Details are foggy but I think it seemed like no air was coming through the hoses at all but in recollection I suppose perhaps it could have been that my side posture had pushed both nasal pillows into a position where both holes were completely covered.. who knows? Anyway I remember asking SIri what time it was and hearing "It's 3:00am Yawn". Then I recall rolling back onto my back and immediately the air was back in a BIG way. So much in fact that I was unable to exhale at all. I looked at the display and it said 19.8 or something. At this point I'm fully awake. I was lying there trying to breathe at nearly 20 pressure and it was impossible to exhale against the incoming air pressure. I kept waiting for the "Auto" to kick in and realize I needed a lower pressure but no matter how I tried it would not adjust on its own. Finally I just held down the button on top of the machine for 3 seconds. I turned it back on and tried to go back to sleep. Not sure if I really got any sleep after that. Also my alarm was set for 6:30 anyway. I'm still really curious what the heck happened. Perhaps the charts will hold clues.

Also a few more questions have arisen if anyone can be so kind:

On the Sleep Report generated by the machine in the AM... why does the "Usage" time never seem to be accurate? When does it start over? WHat if I take a nap the same day or go to bed after midnight etc..? As an example, for last night the display reads 7:30 but I know I only was in bed from about 12:30am - 6:am but I did take a nap earlier that day but technically that was a different day etc... What's going on?

When I take off the mask in the morning the machine is configured to shut off the air after a few seconds (auto start/stop) but I have noticed that the machine still makes a slight noise and also a small trickle of air can still be felt at the nasal pillows. Will this eventually stop or do I have to keep holding down the power button and shutting it off?

Does the machine register AHI events during the ramp period when it (supposedly) knows you are still awake from the different breathing patterns etc...

If my "period" is set to 1 month., what happens after that? does all the prior month data get erased and overwritten with new data?

Thanks in advance! More to come I'm sure

The machine counts from 12:00PM to 12:00PM...Noon to Noon
ResMed machines run at a low speed for a period of time after you turn them off...That dries the hose a little.

Thanks as usual!

My ResMed internal clock is messed up I think. Sadly I haven't slept anywhere for 7.5 hours in many many years.

edit: actually that does make sense if the nap was between noon and noon. Duh.

Here's the latest for what it's worth...

Try turning off EPR...

and work on mask seal... you've got some really bad leaks.

I can turn off EPR tonight.
I'm not sure how to work on mask seal. I think it all goes to crap as soon as I turn my head. I've tried 3 masks so far.

Can you tell from the chart if I'm getting good seal and sleep during the first hour or two until I start to move around?

Can you or have you tried a different size nasal pillow?
Your leak last night went to hell about 2:20.
Sometimes a different size nasal pillow ends up being more stable and more forgiving when tossing and turning.

Do you have the fleece wraps for the side frame? I found that adding the fleece wraps helped stabilize this mask when I tried it.
