Oxygen

Stationary home oxygen concentrators provide a continuous flow of oxygen by separating out the nitrogen from room air and producing high purity oxygen.

Portable oxygen concentrators also produce high purity oxygen, but are lightweight and can operate from battery power allowing the patient to travel outside the home and even on airplanes.

Portable oxygen cylinders provide high purity oxygen in a pressurized tank which can be taken with the patient to allow travel, but must be refilled at the oxygen provider.
