Pulse flow, as the name suggests, is based on the breathing rate of the user. It is used most when patients are awake and active during the day. Pulse flow delivers oxygen every time the patient takes a breath. The concentrator then rests while the patient is exhaling. The concentrator is able to do this through the use of a built-in oxygen conserver, much like those used on oxygen tanks. For some, pulse flow oxygen does not provide enough oxygen throughout the day. Many individuals rely on continuous flow concentrators, which provides a constant stream of oxygen. A continuous flow oxygen concentrator does not change as a breath is taken, and will only remain on the setting you chose to use. Continuous flow POCs provide anywhere from 1 LPM to 5 LPM depending on your personal needs. These units can also be used 24/7 depending on the instructions from your doctor.
