For me, there seems to be no relationship between leaks and events. I have been on CPAP for 10 years and every time I plot leaks and events I cannot find a correlation. One night I had 95 leaks (bad hose connection) and events were less than 5. Another night I had 0 leaks and 9 events.
I am now plotting just events on a spreadsheet and since using a ResMed f20 Air Fit mask and that and a tweak to my ramp time by my DME I have seen a 36% decrease in my events over a 5 month period. By the way leak readings were so inconsistent. In a 30 day period on MyAir web site they went from 17 at the beginning to 9 on the last day with 9 nights of no leaks and the rest below 5.
My wife and I recently got the F20 Air Fit We use to have Mirage Quattro. What a difference. We just got new mask etc and the connector has changed. It is the quietest connection yet.
We both tried the memory foam F20 Air Touch but it did not work well. Leakage was all over the place.
JWalsh: I use a mirage quattro mask. The cushion is silicone elastomer. I also use a Remzzz mask liner. The silicone makes my face perspire therefore allowing leaks. The mask liner probably leaks as well but there is not the noise associated with not using the liner.
My gripe with masks fitting properly is that the mask is one of the essential parts of delivering air (other than the machine and tube). Yet, no manufacturer has come up with a solution to have the mask cushion fit the different contours of ones face. Instead there have been "band aids" to the problem. Different cushion materials and mask liners are not the solution. Of course the headgear used by the different mask are sometimes a joke as well as these can stretch until adjustments cannot be made.
After approximately 2560 days or 17920 hours of using the same mask and a ResMed machine I have concluded that there is no solution on the horizon to the mask and I am just satisfied that treatment for a serious problem like OSA can be rectified by a machine that pumps air and I do not have to ingest any medication.
it is the pressure during exhale that prevents apneas.
