Rebreather diver with bailout and decompression cylinders. Scuba gas management is the aspect of scuba diving which includes the gas planning, blending, filling, analysing, marking, storage, and transportation of gas cylinders for a dive, the monitoring and switching of breathing gases during a dive, efficient and correct use of the gas, and the provision of emergency gas to another member of ...
Underwater breathing apparatus can be classified as open circuit, semi-closed circuit, (including gas extenders) or closed circuit (including reclaim systems), based on whether any of the exhaled gas is recycled, and as self-contained or remotely supplied (usually surface-supplied, but also possibly from a lock-out submersible or an underwater habitat), depending on where the source of the ...
Another type of small independent air source is a hand-held cylinder filled with about 85 litres (3.0 cu ft) of free air with a diving regulator directly attached, such as the Spare Air. [64] This source provides only a few breaths of gas at depth and is most suitable as a shallow water bailout.

The word SCUBA was coined in 1952 by Major Christian Lambertsen who served in the U.S. Army Medical Corps from 1944 to 1946 as a physician. [1] Lambertsen first called the closed-circuit rebreather apparatus he had invented "Laru", an (acronym for Lambertsen Amphibious Respiratory Unit) but, in 1952, rejected the term "Laru" for "SCUBA" ("Self-Contained Underwater Breathing Apparatus"). [2]
Internally, the blending equipment and diving cylinders must be oxygen clean; all fuels and particles which could be sources of ignition must be removed. [6] [7] [8] The materials chosen for use in the valves, joints and compressors must be oxygen compatible: they must not burn or degrade readily in high oxygen environments. [8]
The purpose of the bailout cylinder is to provide a fully redundant breathing gas supply for use in emergencies where a single gas mixture is appropriate. If more than one mixture is necessary for the ascent, redundant breathing gas is typically split between two or more cylinders carried by the diver, and in penetration diving where the diver is constrained to use the same route for exit as ...
