RE: Non-Vented masks
Does such a thing even exist?
CO2 is dangerous in high concentration. In manned spaceflight and submarines, it's the CO2 that becomes deadly when scrubbers fail.
Please do not experiment with this.
RE: Non-Vented masks
Although I'm no doctor the general consensus here is that reducing max pressure can decrease CAs as well as reducing EPR.

RE: Non-Vented masks
This isn't really a do it yourself thing in my opinion. If you get it wrong, you could lose consciousness and suffocate. It scares me to even talk about it. Someone could try it the wrong way and kill themselves.
Do you plan to have an external exhale port and short hoses or what?

RE: Non-Vented masks
So how does one prevent or slow Co2 washout that contributes to CAs? When I restrict my nostrils to 4mm holes with waterproof tape (using a Wisp mask) my medium respiration rate comes down from 17 or 18 to 15 or 16 and the CAs disappear. My AHI drops from close to or above 5 to -0- or just a little above.
Without the tape, the more pressure the more CAs - the less pressure the more obstructives.
The problem with what I am doing is the tape becomes annoying during the night and becomes a source for awakenings.
RE: Non-Vented masks
That is a mask for a ventilator which is completely different than a CPAP machine, ASV or otherwise.
While on the surface, using that mask would indeed prevent washing out CO2, but only for a few seconds and then all you would have is 100% CO2 and zero O2. You would end up either ripping the mask off in a total panic, gasping for air or if you could not get the mask off fast enough you would pass out and could end up dead.
