Diagram showing the components of a VIE system. A photo showing a VIE system. A vacuum insulated evaporator (VIE) is a form of pressure vessel that allows the bulk storage of cryogenic liquids including oxygen, nitrogen and argon for industrial processes and medical applications.
A lightweight portable oxygen concentrator: Inogen One G3 (2,2 kg) Sequal Equinox, transportable concentrator with a high oxygen flow rate. A portable oxygen concentrator (POC) is a device used to provide oxygen therapy to people that require greater oxygen concentrations than the levels of ambient air. It is similar to a home oxygen ...
An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy .
There are different aviation oxygen systems and delivery methods available depending on the specific application. The oxygen source may be chemical oxygen generators, high pressure portable gaseous oxygen storage systems (gas cylinders), on-board oxygen generating systems (oxygen concentrators), or liquid oxygen systems.

FROGS (Full Range Oxygen Gas System) is a model of chest mounted oxygen rebreather for shallow water and special forces operation, [13] which has been used by the French Navy and the Commando Hubert since 15 October 2002. It is made by the diving gear manufacturers Aqualung. [14] Its working parts are in a dark-blue streamlined rounded shell.

Fuel and oxygen tanks should be fastened securely and upright to a wall, post, or portable cart. An oxygen tank is especially dangerous because the gas is stored at a pressure of 21 MPa (3,000 psi; 210 atm)) when full. If the tank falls over and damages the valve, the tank can be jettisoned by the compressed oxygen escaping the cylinder at high ...
