Old post. Bears repeating.

Blocking off any holes on your CPAP mask is a really bad idea. Death could result.

Yes, you could conceivably do it right and not die. Maybe even improve your therapy. If you miscalculate or do it wrong, you could die.

Oxygen deprivation is particulary dangerous because you can become unconscious without any warning signs. Healthy, fully awake adults can lose consciousness and die without ever noticing anything is wrong. Google "confined space training" to get an idea about how dangerous this is in industrial environments.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.

RE: CO2 and Central Apneas
I think the point is being missed here. TheraVent which is the FDA approved cousin of Provent (approved for Apnea) slows the breathing down - it's high likely that it doesn't kill people.

Anyway I am having great success using it with my APAP. AHI is usually 0 to maybe 0.3 with a pressure of 6. My prescribed pressure as of last time was 12. Even at 12 I had a hard time getting below an AHI of 5. It's simple and it works for me...

Theravent has nothing to do with CO2 retention. You only get that if you block the exhaust vent or anti-asphyxia port.

Theravent is also not intended to slow breathing down. It's intended to increase the EPAP (Exhaled Positive Airway Pressure) and keep your airway open.

RE: CO2 and Central Apneas
With just a little research you'll fine that slower breathing equals increased Co2. TheraVent increases you exhale by a full second or more because of EPAP. In other words your exhale is slower, under greater pressure and last longer.

In many of their research papers TheraVent/ProVent mention the value of the increase in Co2.

Works for me - and in reality that's all that matters...
