Oxygen Concentrator vs Oxygen Cylinder
Oxygen Cylinders
Cylinders of oxygen are produced by a relatively expensive industrial process. An oxygen cylinder needs a special valve (regulator) to release the oxygen in a controlled way and a flow meter to control the flow.
Oxygen Concentrators
Oxygen concentrators are suitable for use in all levels of hospital. They provide oxygen more cheaply than cylinders, as well as making oxygen available in hospitals where a regular supply of cylinders is difficult to obtain. Oxygen concentrators designed for use with individual patients normally give a flow rate of up to 4 litres per minute of near-pure oxygen at relatively low pressure.
