I found a veterinary supply shop in a random comercial district and they have amongst other things a double rotameter which can measure up to 10L/m of two gases with a safety valve to shut off one if the flow of the other decreases.
Is there any reason that this wouldn't work for humans? Google says we breath 13 pints of air a minute which is considerably less than 20L
