Types of Oxygen Cylinders
There are three common types of oxygen cylinders, which allow at-home oxygen therapy. These devices are called oxygen delivery systems and are used to transport oxygen into the body.-
Compressed Oxygen Cylinders
-
Compressed oxygen cylinders come in a tank, which stores oxygen as gas. Attached to the tank is a flow meter and a regulator, which are used to adjust the flow of oxygen. Compressed oxygen cylinders come in various sizes ranging from large stationary tanks to small tanks, which can be transported. These tanks are generally home delivered and stored in a secure corner of a room. A key is needed to turn the tanks on or off and must be replaced when the tank becomes empty.
Liquid Oxygen Systems
-
Liquid oxygen systems consist of a large silver main tank and one or two portable tanks. Portable tanks are used for travel outside of the house and can be refilled from the main tank. The portable tanks generally weigh about 8 to 10 lbs., and can be carried with a cart or a shoulder strap. If the tank is not used frequently, the liquid oxygen will evaporate, so it is suggested that you fill the portable units right before use.
Oxygen Concentrators
-
Oxygen concentrators concentrate oxygen from the air and deliver it to the body. These tanks are not portable, however, a smaller portable tank will be delivered along with the device as a backup for power failure and for transport. This device is generally used for patients that only use oxygen at night, but they may be used 24 hours a day.
