Oxygen concentrators

An oxygen concentrator is a device that concentrates the oxygen from an ambient air by selectively removing nitrogen to supply an oxygen-enriched product gas stream.

Since the early 2000s, many companies have produced portable oxygen concentrators. Typically, these devices produce the equivalent of one to five liters per minute of continuous oxygen flow and they use some version of pulse flow or “demand flow” to deliver oxygen only when the patient is inhaling.

Usually, “demand” or pulse-flow oxygen concentrators are not used by patients while they sleep. There have been problems with the oxygen concentrators not being able to detect when the sleeping patient is inhaling. Some larger portable oxygen concentrators are designed to operate in a continuous-flow mode in addition to pulse-flow mode. Continuous-flow mode is considered safe for night use when coupled with a CPAP machine.

The COVID-19 pandemic increased the demand for oxygen concentrators.
