Beanie, you have to show your working!

How did you get 0.03?

physiological value in expired "air"
N2 73%, O2 16%, vapored H2O 6%, CO2 4%
So ppo2 drop from 0,21 to 0,16 in fact 0,03 to 0,05 you have to test it

I think for that amount of extra O2 it's not worth worrying about. In fact, it'll probably keep the setpoint nearer what the deco computer thinks it is.

The other option is to house the cells, battery and the solenoid in the Inhale CL. It's closer to the DSV but everything will have to happen in the CL. Getting the O2 to the solenoid will be fun...
