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. If their breathing rate increases, the machine will react and release a bolus, or pulse dosage size, with each inhalation. The flow rate is based off the bolus.
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.
Pulse dose portable oxygen concentrators are able to deliver anywhere from 450 ml per minute to 1250 ml per minute of oxygen in short pulses. Pulse dose portable oxygen concentrators are typically recommended for low oxygen requirement patients who require up to 2 LPM of oxygen.
Although there are pulse flow units that can be used 24/7, it should be noted that pulse dose units are not compatible with CPAP or BiPAP machines. Here is a list of pulse flow portable oxygen concentrators that can be used 24/7.
