Oxygen Cylinders / Compressed Gas
Oxygen is stored under pressure in an oxygen cylinder equipped with a regulator or oxygen conserving device that controls the flow rate. Because the flow of oxygen out of the cylinder with a standard regulator is constant, an oxygen-conserving device may be attached to the system to avoid waste. This device releases the gas only when you inhale and cuts it off when you exhale. Oxygen can be provided in a small cylinder that can be carried with you for mobility or provided as back-up in case of power failure.
Below you will find cylinder durations charts for the most common small cylinders and prescribed flow rates.
