Diving OC like a CCR
By Bruce R. Wienke, PhD and Timothy R. O'Leary
Open circuit divers also optimize their dive time, while minimizing decompression requirements, by making gas switches at various depths. Obviously, gas switching can be dialed to hold gas fractions constant on ascent; or, we should say, relatively constant on ascent, with constancy increasing with the number of switches.
