Oxygen Concentrator -
|An oxygen concentrator is an electrically powered unit that is usually stationary. The concentrator produces its own oxygen by drawing in room air and filtering out the oxygen and, therefore, requires no refills or replacement.|
Oxygen Cylinder -
|A cylinder contains compressed or pressurized oxygen. Oxygen cylinders, sometimes referred to as oxygen tanks, are available in a variety of sizes and are primarily used to provide portable oxygen away from home. They can also serve as a backup to an oxygen concentrator.|
Conserving Device -
While many oxygen systems deliver oxygen continuously while you breathe in and out, a conserving device can be attached to either your oxygen cylinder or portable reservoir unit, to supply oxygen to you only while you inhale. This way, the conserving device limits or conserves the oxygen and, thereby, extends the length of time your oxygen will last. The use of a conserving device should be carefully evaluated for each individual.
Liquid Oxygen -
|Liquid oxygen is stored in thermos-like containers called reservoirs. The liquid converts into a gas before it leaves the reservoir, making it ready for you to breathe in. Liquid oxygen requires no electrical power and portable units are designed for you to fill from the reservoir. The liquid reservoir is refilled on a regular basis by Medigas.|
