What are the different types of portable oxygen systems?

There are three types of portable oxygen systems. Oxygen is delivered from each of the following systems to the patient via a regulator/valve, plastic tubing and a nasal cannula: • Compressed Gaseous Oxygen Cylinders These are steel or aluminum cylinders that contain gaseous oxygen under very high pressure. The cylinders vary in size, with the portables ranging from 1 to 6 liters in capacity. This allows the patient to carry these in a backpack or wheeled cart during short trips. A full cylinder can store well over 100 times its container volume of expanded gaseous oxygen. • Liquid Oxygen Cryogenic Containers These are double-walled and vacuum insulated containers that store liquid oxygen at (or below) its boiling temperature of 183oC. Its 860:1 expansion ratio allows a very high volume of gaseous oxygen to be stored in a relatively small container. Base units, which have a capacity of between 20 to 45 L of liquid oxygen, serve as reservoirs for transfilling the smaller portable units.
