Set inlet dependency based on outlet (simulate breathing)

Set inlet dependency based on outlet (simulate breathing)

Set inlet dependency based on outlet (simulate breathing)

(OP)
Hello,

I'm not sure if this is possible so looking for a bit of help. I have a design that a user breathes into, each breath cycle the o2% drops by 5% (being replaced with CO2). Is there anyway I can set the inlet dependency for the gas concentration to be a factor of the outlet?

ie.

Outlet cycle 1 0-2 seconds = ambient air = 21% O2, 79% Nitrogen
Inlet cycle 1 2-4 seconds = 16% o2, 79% Nitrogen, 5 % CO2

There is then some mixing in the unit so the next inlet breath would be based on 5% less o2% than that inhaled on the previous cycle.


Thanks
Craig
