Types of Oxygen Delivery Systems

Oxygen Concentrators:

Oxygen concentrators produce oxygen by taking in room air and sifting out the oxygen. Concentrators are powered by electricity. Because oxygen concentrators make their own oxygen, they do not need to be replaced or refilled regularly.


Oxygen Cylinders:

Oxygen cylinders are metal tanks that contain oxygen compressed under high pressure. Oxygen cylinders lose oxygen only when they are used. They come in a variety of different sizes.


Liquid Oxygen:

Liquid oxygen is made by super-cooling oxygen gas, which changes it to a liquid form. The liquid turns back into a gas before leaving the container and remains as a gas when it is breathed in. Oxygen in liquid form takes up much less room and can be stored in a special thermos called a resevoir. Portable units are filled from a reservoir for travel and use outside the home. Liquid oxygen systems lose oxygen even when they are not in use.


Oxygen Conserving Devices:

Many oxygen systems deliver oxygen continuously (while you inhale and exhale). Oxygen conserving devices are used with your oxygen delivery system to make the delivery of oxygen more efficient by reducing the amount of oxygen that is wasted during exhalation. Conserving devices allow your oxygen supply to last longer. This may cut down on the number of deliveries required by your oxygen vendor and extend the life of your portable unit.
