My girlfriend is taking a biology class as a prerequisite to a nursing degree, and in this process she was used as a guinea pig for VO2 and VCO2 measurement. This was interesting because she metabolized about 2.0 litres of Oxygen in a 7 minute period and output 1.5 litres of CO2 in that period of time. She could stay down on my rebreather for over 30 hours!

I'm thinking of signing up for a non-credit class that deals with metabolism for the sole purpose of having mine measured. They test you at rest, medium, and heavy workloads. I know that everyone is different, and that a single individual can vary from day-to-day, but I think it would be interesting to be tested.

Has anyone gone through the process of being tested for VO2 and VCO2 levels?

Aloha,
Charlie

Hi
There are facilities and doctors who are willing to do VO2 max testing and they can also help in this area

Your canister if the canister housing is designed correctly scrub around 200 to 260 L of CO2 but a bad design could reduce this to 50 L and of course depth is an important considertation

For practical purposes use 1 L o2 used and 1 L of co2 produced

But this of course does not account for those folks (who like PFO occurances make up a fair percentage of divers) that are co2 retainers- So the classes would be very good to discover if you may be a retainer or not-

I imagine your girl friend is in good shape and eats allot of protein and watches her carbs
