discussions like this are always informative. It brings me to a train of thought from the design/mfg perspective however. That being, was there a specific reason that the O2 button was put on the inhale lung...or alternatively, it ended up on the inhale lung and a valid reason for it was found later?

See earlier in the thread. You might have missed it but I posted the email response as to the reason direct from ISC.
