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 ...
Most humans can function at rest with an oxygen level of 15% at one atmosphere pressure; [1] a fuel such as methane is combustable down to 12% oxygen in nitrogen. A small room of 10 meter 3 has 2.08 meter 3 (2080 liters) or 2.99 kg of oxygen which would occupy 2.62 liters if it was liquid. [2]
This is a big advantage in mobile emergencies. The option to fill standard oxygen cylinders (e.g., 50 L at 200 bar = 10,000 L each) with high-pressure boosters, to ensure automatic failover to previously filled reserve cylinders and to ensure the oxygen supply chain, e.g., in case of power failure, is given with those systems.
This increases the device’s size and weight (approximately 18–20 lbs). [13] With on-demand or pulse flow, delivery is measured by the size (in milliliters) of the "bolus" of oxygen per breath. Some Portable Oxygen Concentrator units offer both continuous flow as well as pulse flow oxygen. [14]
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.
The cylinders used were dural light-alloy cylinders holding 800 litres or RAF steel wire-wound cylinders holding 1,400 litres of oxygen (both at 3,300 p.s.i.; 227.5 bar or 22.75 MPa). The expedition had 8 closed-circuit and 12 open-circuit sets; the open-circuit set used 1 RAF cylinder or 1, 2 or 3 dural cylinders; with total set weight 28 lb ...

The cylinders used for emergency gas supply on diving bells are often this shape, and commonly have a water capacity of about 50 litres ("J"). Domed bottoms give a larger volume for the same cylinder mass, and are the standard for scuba cylinders up to 18 litres water capacity, though some concave bottomed cylinders have been marketed for scuba.
