If you have a machine that can provide some feedback in numbers, did you change the mask type on your machine to full face type? If not, the numbers may be skewed. If you did make the change to your menu, what was your leak rate? If the full face mask leaks horribly, the PAP machine won't be able to compensate for the leak and all your positive air pressure therapy will go blowing out with the leaks.
shannie76, Note you are replying to a post over a year old and not likely the person you are replying to is still around. Look at my post below this from a year ago... still holds. You can put ice in the humidifier but the humidifier will melt it so it can become humidity (think steam). The post that ice water will blow through just doesn't make sense. Control the temp in the room where you sleep and if you don't need humidity, turn it off. I can take it or leave it and if I do have humidity on, it is very low.
I suggest that if your current mask cushion isn't quite right to first try one in either one size up or one size down. In your case, down (small) would seem a good choice to try. Cushions are not that expensive and once you have found the right size, you will be glad you did the experiment.
I have not come across any technician who was able to fit a mask. Look at eye glasses... there are three numbers on a frame: aa/bb/ccc where aa is the width, bb is the width of the nose section and ccc is the length of the stems. I find the best fitting glasses are the ones that conform to the width of my nose (the bb number).
Another thing to consider on a mask is the head gear. The Amara View has too thin straps and they bit on the back of my head and neck. My wife makes me little pillow pads to put the the back part. The Simplus head gear is much better designed but the greater surface area of the cushion makes for the most chance to find leaks; especially if bumped a bit at night.
The DME where I was initially "fitted" would not let you actually try a variety of masks for comfort and feel. They decided which mask would be best (I think it was what they had on hand) and then give you that mask as your own to stick on your face in the office. How can any patient know if the mask is comfortable, fits right or is best suited? They can't. I am proactive and figured the mask issue out on my own... you have to keep at it till you find what works for you. What works for me may not work for anyone else in therapy!
If you do decide another sleep study is warranted, make 'em give you a copy of the results. YOU are the person who ultimately pays for the thing. Look at the results and google the incomprehensible medical babble and stuff will make some sense and YOU can decide if apnea is a contributor. One more thing... if you are a "light sleeper", that also is a possible symptom of sleep apnea. The reason you think of yourself as a light sleeper may be you never get to the deeper stages of REM prior to therapy, I had vivid dreams and was up multiple times during the night to make potty runs. I guess you could say it was the result of being restless but once I started therapy, I sleep like a log and almost NEVER wake during the night and hardly remember a dream. I also don't nod off during the day.
Again, this time, as you explore treatment options, be proactive and YOU get in front of the process so you are better
able to evaluate whether the suggestions you receive seem to be the best. If they don't make sense, as is often the case,, understanding what is going on with tests and demanding explanations will really be your best chance of licking
If you jaw goes slack in addition to your facial muscles, the mask WILL leak as your jaw slides backwards a tad and opens your mouth. I do use a boil & bite mouth guard. This mouth guard is placed in boiling water out of the box and then you stick it in your mouth and bite down to it so it conforms to your bite. It keeps my jaw from going slack and I get almost no leaks. I also use an Amara View with almost no leaks night after night and previously used the Simplus sleeptech mentioned. That thing leaked because it didn't seal perfectly against my face. The leaks were not bad and didn't affect therapy numbers BUT were annoying as air was in my eyes. I then learned mask pads fixed that issue and the mask became very workable. It is just not as comfortable as the Amara View. It is also critical to get the right size cushion and this can take some experimentation. Get a mask and then try a larger or smaller cushion; they are not all that expensive. I am fairly large and the DME techs always think I need a bigger size cushion than I actually do.
DME = durable medical equipment
These are the folks who hand out PAP machines and supplies as well as wheel chairs and hospital beds in many cases.
My pressure on a bipap is 25/21 and I have turned off the ramp so I can't tell you. I like it as high as possible as soon as possible as it helps my nasal passages to open up right away and allows me to sleep immediately.
If you had a sleep study and characterize it as "unremarkable", did it show significant obstructive sleep apnea? Numbers?.....
In any case, the only sleep apnea related issue in my life that caused me to get very drowsy was low blood oxygen levels caused by OSA. What were your blood oxygen readings during the sleep study? In my case, I could fall asleep while riding a motorcycle or operating power tools...
What would happen if you asked your doc to contact the DME and request a machine swap out? If you are insisting the machine may be malfunctioning, the doc will likely have his staff push the DME. I can't imagine why a machine would get hot although I never use heat for my water reservoir or hose so am not an expert here. Your apnea numbers, while better are still not where they should be and it could be that the machine is malfunctioning and causing this; dunno but I would look at getting rid of that machine for another. If that fixes things, good and if not, perhaps your prescription isn't optimal for keeping your airway open OR is causing central apneas. I believe the sleep doc CAN look at OSA vs central apneas if they want to so that info might also be a good tool to figure out what is happening.
