Exit Bag With Compromised Lungs

[77redbike]

I have somewhat compromised breathing (mild or early COPD) and am trying to decide if an exit bag will work. I would think it would if the bag is on the large side and there is not much leaking around the neck. I realize that each initial breath will be breathing in a lower amount of gas but I would think also exhaling a lower amount of CO2. If the bag is larger than normal and is initially filled with inert gas I would think that the per cent of oxygen would be lower and therefore could compensate for the lower breathing capacity. I'd appreciate any comments.

good luck, common problems seem to be the bag not being airtight and SI kicking in at the last moment and ripping it off
