  2. Maximum operating depth - Wikipedia

    en.wikipedia.org/wiki/Maximum_operating_depth

    In which pO 2 is the chosen maximum partial pressure of oxygen in atmospheres absolute and the FO 2 is the fraction of oxygen in the mixture. For example, if a gas contains 36% oxygen (FO 2 = 0.36) and the limiting maximum pO 2 is chosen at 1.4 atmospheres absolute, the MOD in feet of seawater (fsw) [ Notes 1 ] is 33 fsw/atm x [(1.4 ata / 0.36 ...

    en.wikipedia.org/wiki/Scuba_gas_management

    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 ...

    en.wikipedia.org/wiki/Scuba_gas_planning

    Decompression gas is the gas intended for use for planned decompression. it is generally chosen to accelerate decompression by providing a relatively high oxygen partial pressure at decompression stops. it can be optimised to minimise total decompression time, or selected from what is already available, and close enough to optimum for practical ...

  5. Self-contained breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/Self-contained_breathing...

    The endurance of the cylinder can be calculated from the volume, pressure and breathing rate of the user. The formula: volume (in liters) × pressure (in bars) / 40 (litres per minute) - 10 minutes (the 10 minutes is a safety margin, or reserve), so a 6-liter cylinder, of 300 bar, is 6 × 300 / 40 - 10 = 35 minutes working duration.

  6. VO2 max - Wikipedia

    en.wikipedia.org/wiki/VO2_max

    V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...
