about steady states I have no time to do and more not enough facility

do to the right computations but I guess that with the right diluent and the right O2 flow the ppo2 could stay between the good value.

Dont forget the SCR do that

Anyway if the thing is really impossible and if the the m CCR submatix is really CE aproved there is a way to follow, sort of a dispensation for mCCR Rebreather based on what have been done ( jurisprudence in french ) perhaps one of our lawyers here on Rebreather World could answer?

Cheers

hello marc, in SCR it is no problem at all, but in CCR..

the test is the following: you put the breathing machine at a certain breathing rate, pressure, temp, and a given CO2 inflow, you wait for steady state, and you see what the PPO2 is..

the CO2 inflow must be put on certain flows, the minimum is 0.4 l/min, the max 3.0 l/min, (means oxy consumption of 0.44l/min, till 3.33l/min)

anything you do, with a constant flow of 0.8l/min oxygen, your PPO2 will rise... (at the minimum settings)

regards
paul
