Changed Machines. Lots of therapy Questions Now

EERS has made a consistent positive change for your therapy and comfort. Very good story. I think I'll add a link to this in the EERS wiki.

I should say another interesting part of switching to a new machine is that the resmed machine is allowing me to have a treatment pressure of ~3 cm h2o lower than my dreamstation. That seems to have led to me keeping the mask on longer than I ever have before. (10 is a piece of cake compared to 13). Consider that an endorsement of the machine that I've been able to all but eliminate obstructive apneas. Something i was never able to do on the other machine. Even though it caused a LOT of clear airways that seems to be remidied for the most part now too.

I'm new here and to the data logging CPAP hardware I'm now using. I read the entire thread, and I was stunned to learn about EERS and that it can really be caused by not (re)breathing in a small amount of CO2. I've been learning so much reading the forum, obviously I need to read the entire WIKI! I''ll make it happen soon.

I am curious though....since we can quantify our flow rate and leakage using the CPAP hardware, why can't we totally address this issue by plugging the vent holes one at a time instead of increasing the hose volume? My mask has a wealth of small vent holes, so plugging one or two of them and retesting seems logical to me.

Plugging vent holes at the mask simply gives unreliable results in rebreathing volume and is a safety issue. CPAP is designed to generate about 5 to 7 times your respiratory flow to prevent rebreathing expired CO2. By providing a known volume of rebreathing space and moving the vent, we get predictable results and a safe flush of all excess rebreathed air at the vent, maintaining the design flow rate of the machine and mask. I for one won't be recommending an undemonstrated approach to something that can have serious health consequences.
