As it is i plan on getting this nailed down so not only I understand the data and am getting proper therapy but so others will have the info they need. Especially since the Apex XT Auto Cpap sells for $385 new and $225 for a low hour factory refurb. This price could help a lot of people get an Apap with software so they know if they are getting proper treatment.
I wonder how many people are using a cpap nightly and not getting proper therapy?
From what I can tell I was getting possibly improper therapy for 16 years and blamed my sleepiness and falling asleep in a chair and drowsiness while driving on high blood sugar. I plan to find out now for sure.
I am hoping that some of the new info presented in some of these posts will allow the more educated members to ascertain what's going on here and how to read the graphs that the software produces.
Yes, I somehow don't breath through my mouth or the numbers would have gone up. I haven't since the 1st night of using the nasal mask. Tried letting air out through the mouth and the air pressure/velocity built up making me very uncomfortable. I would also have difficulty conversing - sounding like an incoherent chipmunk - and can't make a conversation so I think the jaw just clamps up. You may wish to try a makeshift band of sorts and see if helps before buying one.
Generally speaking, not sure if mustaches or beards will add to leakages and I'm sure there are workarounds or different masks solutions available.
I do wake up at night due to leaks blowing at the eyes or cheeks and it's usually due to my having turned to the side against the pillow, causing the mask to shift. I run my hose through the strap at the top of my head (has an opening for that & use a rubber band to further hold it in place) so it doesn't gets entangled with the blanket and pulls the mask down.
Seems the wisp is not meant to be very tight fitting but enough for the nasal pillows to just puff up under pressure against the face and upper lips forming a seal. As many have shared, its not meant to ride all the way up the nose bridge. Any other mask with a forehead guard/frame would probably help mitigate this latter issue once it's been set correctly. I don't own one, so can't really tell if that really works in practice.
I usually put the whole mask on and lift (stretch) the mask off my face/nose with the machine on to get a good clearing of dust (if any) out of the mask and then rest it back on the face before I start breathing. Others probably have their own routines or regiment. So in effect, my straps aren't set so tight that I can't do that.
Hope the above helps.
OK, I tried an experiment last night. I read on another forum where some have experimented using waterproof tape to seal the mouth as a short test while some have used it long term and favor it over a chin strap. My idea was that I must have an open mouth and wanted to see how much the leaks would drop.
To my amazement, it didn't go down. But instead stayed almost flat at just under 60 all night. My AHI went up but only to a 4.00, my cmH20 went higher in a few places than normal and I woke up with a sensation in my stomach that was not pleasant. After I ate I did some belching that seemed to clear that up. So, I guess air was forced into my stomach.
This really blows the test results I expected. Now, I'm thinking that a chin strap will not help nor will a face mask.
I am beginning to think that perhaps since my numbers didn't go down that maybe the leaks I'm getting is normal. Or who knows what.
What ideas can you give me for this collection of strange data? Sigh, why couldn't this switch to an apap been simple. The more I research the more that doesn't add up and I am totally frustrated. I guess I need to talk to my repiratory therapist again and see if we can come up with an idea of what's going on and what data equals good therapy.
At least you seem to have ruled out the mouth breathing part. Go with it for a few nights and see if it's the same. For the leak reading to stay flat would appear to indicate that the setup has such a base leak rate, although 60 lpm seems high. I have yet to exceed 51 lpm (and that's when I had a major leak event which spiked the reading). Hopefully someone using the same APEX Wizard mask can share their experience.
I find my AHI definitely shoots up if I didn't stick to good sleep hygiene - like eating supper late in the night before bed, or snacking, etc. My "bad" night chart posted earlier was due to a few drinks that night.
Even with such precautions, there are days when things really go south and I wonder what happened. It takes a few days to settle down.
