As noted in Cyborg (the novel on which the TV series was based), Austin's significantly reduced biological body mass requires far less oxygen and produces correspondingly less carbon dioxide; an unchanged lung capacity is thus vastly more efficient. Noteworthy Moments: This episode features bionic swimming and deep-sea fishing.

Although theoretically trimix can be blended with almost any combination of helium and oxygen, a number of "standard" mixes have evolved (such as 21/35, 18/45 and 15/55—see Naming conventions). Most of these mixes originated from starting by decanting a given pressure of helium into an empty cylinder, and then topping up the mix with 32% nitrox.
Medical use liquid oxygen airgas tanks are typically 2.4 MPa (350 psi). [citation needed] All equipment coming into contact with high pressure oxygen must be "oxygen clean" and "oxygen compatible", to reduce the risk of fire. [3] [4] "Oxygen clean" means the removal of any substance that could act as a source of ignition. "Oxygen compatible ...
