<-- newbie.

I'm still a bit baffled by the CO2 and O2 tables.

When it says, for example, "Ventilate 1:30", does that mean exhale slowly over a minute and a half, or does it mean exhale completely and then hold your lungs deflated for 1:30, or does it mean breathe normally for 1:30? It says resting period, and I guess the third one seems most restful. Right?

I assume the hold time is measured from when you stop inhaling to when you start exhaling. I assume also that one takes as deep a breath as possible without actually packing. Right?

Very helpful thread, I'm loving it!
