A pSCR can be considered as universal gas extender for any depth, so any driving gas.

A diver using a single cylinder of breathing gas can therefore dive for much longer periods than using a recreational open-circuit configuration. With pSCR equipment, a very small amount of breathing gas is released every time the diver inhales. With active SCR (aSCR) equipment, in contrast, a small amount of -- cgit v1.2.3-70-g09d2
