50% leak rate
#31
RE: 50% leak rate
CPAPnovice, you have done a good job of taming leaks in the course of this thread and while the focus has been on the leaks, I'd like to make some additional suggestions.   Your flow limitations have been consistently high at 9.0-20.0 EPR 1.  The image below shows the flattened inspiratory peaks that should be smooth, but instead look like flattened wrecks at a junkyard.  The For Her algorithm is keeping pressures generally below 12.0, but I really think you would sleep better and be more comfortable with EPR at 3, and this would also reduce your hypopnea event rate.  Obstructive apnea are rare in your posted results, and mostly appear to be positional when they occur, as in your most recent chart, so I'm not concerned with the lowered EPAP pressure you will experience with EPR 3.  The trick will be to start with your current pressure settings and increase minimum pressure if or when you feel starved for air, or if obstructive apnea increase.  This may actually improve your leak rate as exhale pressure will be lower.  Please consider increasing the EPR setting and see if it resolves some of this apparent inspiratory effort which likely contributes to the under-reported RERA events.

RE: 50% leak rate
unfortunately leak reduction caused by using full face mask.  i started with nasal mask. i am unable to control leaks with nasal mask due to mouth breathing.  chin strap did not work. strap from Supplier #37 did not work. it appeared to keep my mouth closed but i still had huge leaks probably due to mask becoming unsealed. i did not like chin strap from #37, it is too close to eyes and i felt it was pressing on eyes and this is just too dangerous.   i feel the only chance i have is with full face mask. the only time i get no leaks when mask is is very tight. sometimes i wake up and my nose hurts from mask being very tight. i changed my machine to epr = 3.  if for her machine cant go above pressure 12, why would anyone would want it? i have regular airsense 10. may be i should stop using for her machine?

RE: 50% leak rate
Why do i have strange event with my full face mask (f30i)? i usually sleep on a side and test mask fit prior to using machine. i woke up on my back and air was blowing from everywhere around my mask, when i turned on a side, air was normal. what was happening? is it mask leaking in specific position only?
