DeVilbiss IntelliPAP AutoAdjust settings

I recently purchased a DeVilbiss IntelliPAP AutoAdjust & a ResMed Nasal Pillow. The machine works great. I can fall asleep with no problems. I am waking up because the pressure is too high. I'm guessing that when the machine has finished ramping the final pressure setting is too high. What would be the best way for me to correct this problem? Should I start by lowering the "Upper Limit" a little each night until it isn't blasting air and waking me up?

No, the lower one, but why not check out what it is? You can get the code # each a.m. off the screen (see manual), enter it in the little box on either Cpap.com site (on pg of machine), which I find easier, or DeVilbiss and you'll get lots of data, including pressures.

Thanks, I'll start checking/following my data.
Right now my machine is set like this:
Upper Limit 18 cmH20
Lower Limit 4.0 cmH20

So, it's my Lower Limit that I need to adjust to stop it from blasting too much air after the ramp cycle. Should I adjust it to a Lower Limit of 3.5 cmH20? Or do I need to go the other way and bring it up to 4.5?

Whoops - your setting of 4 is the default low setting possible on the machine and is usually impossible to breathe at - not enough air at all, and we normally have to raise the pressure until at least 6 or 7, and more so over time. What you're having may be that the mask isn''t fitted properly, because once it's on (I presume you put it on before turning the machine on) you should not be aware of the air pressure to any extent, let alone what you're experiencing. BUT if your machine raises the pressure overnight to high ones (you can, of course lower the 20 setting to e.g. 15) there's usually a reason, like you either require more pressure or something else is wrong... but without software results it's really almost impossible to guess what. What were your results of the sleep study? Can you download SleepyHead (free) from the 1st note on the page (Pugsy's Pointers) and link one night's results here after screen shotting on Imgur.com?

You've lost me... What do you mean "lower the 20 setting to e.g. 15"? Ug, I feel like I have no idea what I'm doing with this machine. I just don't want the thing to blast so much air through my nasal pillows that I end up taking it off every night.

The high setting is not the one that matters in the same way the lower one does. The lower one, is normally set (as dictated by your sleep study results) to a place - not 4 -where it won't take too long for it to climb to 'catch' apneas that might occur e.g. at 10 or 12 or 17, based on the pressure you normally stay at for 90-95% of the time according to software. If you leave it at 4, it'll take forever to climb and may well miss many apneas that occur at higher pressures. The high setting (e.g. 20 or lower) can be left 'open' at 20 (the default machine high), but it's better to have it set a few cms above that 90-95% place - it's just not as crucial as the low setting for preventing apneas by keeping your airway open better.

I understand you want to escape the blast but you need to get hold of your study results (not just the one pg 'summary') so you can see what pressures were actually recommended, rather than what your doctor 'prescribed' (4-20), something done all too often by docs who don't actually understand how the machines work (or why they don't). Also, if in fact your study called for you to have higher (low #) setting e.g. 10, 13, 16, then a Wisp nasal mask may not be the best choice as it's more likely to not stand up to higher pressures. Have you ever tried a full face mask?

DO get a copy of your sleep study - yours by law - and do read some of the info at least under the light bulb (top of all pgs) and DO download SleepyHead so we can see what's going on with pressures, leak rates, etc. etc. and help you adjust. Without knowing more about you and your results, we can't help very effectively.
