If 15 LPM is uncomfortable how much lower would people be willing to go / is it safe to set it any lower?
I don't think it's got anything to do with comfort level.
You can do it of course, it doesn't do any harm.
But there is no reason why CO2 levels should rise if you continue to breathe normally. This only happens when you hold your breath or breathe extremely shallowly. You won't do both.
When everything is ready and you pull the bag down for the last time, then you breathe in deeply beforehand, breathe out while pulling it down and then continue as normal.
Hyperventilating lowers the CO2 level AND increases the oxygen concentration in the blood.
You can do it, but you don't have to
I wonder why they put that in there..................That increase of oxygen concentration - will that be enough to cause a problem?
