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 takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.
On-board oxygen generating systems (OBOGS) bleed compressed air from the engines, enrich the oxygen content by removing nitrogen using an oxygen concentrator, and regulate the supply to cabin pressure and temperature. They are continuously available and producing fresh gas when the engine is running.
Pulling down on one oxygen mask starts the oxygen supply for that mask only. The entire system can usually be reset in the cockpit or in some other location in the aircraft. [citation needed] A decentralized gaseous system, often called a pulse oxygen system, [4] is used on some modern airliners such as the Boeing 787. These systems have a ...
A home oxygen concentrator for a person with emphysema Nasal cannula Non-rebreather mask. Oxygen can be separated by a number of methods (e.g., chemical reaction, fractional distillation) to enable immediate or future use. The main methods utilized for oxygen therapy include:
Uses compressed oxygen. Uses an oxygen-generating solid. This involves a chemical reaction between potassium superoxide with exhaled water and carbon dioxide. A chlorate candle has to be struck to start the device. To reduce pressure buildup from use, a pressure-relief valve with saliva trap is included.
A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
VPSA systems apply pressurized gas to the separation process and also apply a vacuum to the purge gas. VPSA systems, like one of the portable oxygen concentrators, are among the most efficient systems measured on customary industry indices, such as recovery (product gas out/product gas in) and productivity (product gas out/mass of sieve material).
