An oxygen cylinder is a high-pressure, non-reactive, tempered steel container for compressed gas (O2). This cylinder is used for medical, therapeutic, or diagnostic purposes. It gives the provision of supplemental oxygen to maintain aerobic metabolism during patient transport. Oxygen Cylinders have a finite amount of oxygen compressed within them and inhaled by the user until it runs out. That supply of oxygen is gradually reduced until the tank runs out and needs to be refilled or replaced. Oxygen cylinders deliver oxygen on Continuous Flow.
Oxygen cylinders are used in hospitals for pressurized oxygen therapy to treat numerous medical aliments such as emphysema, asthma, and pneumonia. This medicinal form of oxygen is typically kept in medium-sized aluminum canisters equipped with pressure regulators and release valves.
