humm. 6.3 AHI isn't too bad for one night. AHI of 19.5 not good though. Hmm... Below 5.0 (daily) is more acceptable though.
The leaks seem a bit high. But the machine should be able to compensate.
I use a Quattro FX and I get 0.0 leaks unless I take the mask off to make a late night pit stop or I messed up & didn't wash my stuff...
Once or twice I had to re-tighten the straps to handle the higher pressures and at such times I used the mask leak test function from the front panel menu. That will run up the pressure for you so you can check to see if the straps are stretching on your head gear.
Very handy trick!
If you have stepped through all that mess and still have a 5L/min leak then maybe your face contour doesn't quite do well with your current mask and change in mask design is in order. ( I burned through 5 different masks that way, till I hit the Quattro FX. )
See how it goes for the rest of the week!
If your AHI can get below 5.0 each day you're doing great!
The cheyne-stokes issue will be for the other experts here.
Good Luck & stay in touch!
Have gone back to my Resmed Mirage Ultra Nasal mask and a chin strap. With that I am getting AHI's of 4.5 and AI's of .1, but the leak is consistently 22 which indicates that I am still opening my mouth some at night. The Mirage Quattro I got good results for about 2 nights and then the AHI and AI kept on going up each night, although the leak factor was only 2. I am soon going in to my physician for an annual checkup and I will see if he can solve the problem. I do find the quattro more comfortable to wear but the results are poor. ArfitoJr
