Patients who require smaller amounts of supplemental oxygen often use a high-pressure cylinder system. With this system, oxygen gas is pressurized to 2000 pounds per square inch (PSI) and stored in aluminum cylinders. Oxygen cylinders are available in various sizes to offer you the option that best fits your lifestyle. How long an oxygen cylinder lasts will depend on the size of the cylinder and the flow rate, measured in liters per minute (LPM), as prescribed by your physician.

A regulator or conserving device is attached to the top of the cylinder to adjust the output and concentration of the oxygen you’re receiving, as prescribed by your doctor.  Then, the oxygen is delivered to you through a nasal cannula or, if prescribed, a face mask.
