So far this is all Greek to me and I'm not really grasping any of it. I do know altho I felt no leaks my sleep lab manager when assisting me w/the fitting of two masks I was having trouble with said the one mask was of no value to me as we could not get it adjusted comfortably and still maintain an acceptable leak rate (when checking fit and leakage w/machine at my pressure). The nasal pillows we could fit somewhat comfortably and still maintain an acceptable leak rate - except that the fit wasn't that comfortable after an hour or so.
So, now a third mask. This time it is the ComfortLite 2 which has remained comfortable for 5 nights now.
Scripted Pressure is Inhalation 6, Exhalation 3. Resmed S8 Elite w/Humidaire 3i. Mask set for Ultra first 4 nights, for Swift last night.
Pressure: 5.6 - Leak: 0.36 - AHI: 7.4 - AI 0.2 - HI: 7.2 - Ultra
Pressure: 5.6 - Leak: 0.42 - AHI: 4.3 - AI: 0.08 - HI: 3.5 - Ultra
Pressure: 5.6 - Leak: 0.52 - AHI: 5.6 - AI: 0.4 - HI: 5.2 - Ultra
Pressure: 5.6 - Leak: 0.50 - AHI: 13.6 - AI: 0.4 - HI: 13.2 - Ultra
Pressure: 5.8 - Leak: 0.60 - AHI: 13.8 - AI: 0.2 - HI: 13.6 - Swift
Tonight I'll select yet another Mask setting & see what results I get. It sure would be interesting to know how low my 02 sats go during the hypopneas.
