Continuous flow
Continuous flow oxygen concentrators
Continuous flow delivers a steady stream of oxygen whether you’re breathing in or out — needed for some prescriptions, for higher oxygen needs and often for sleep.
Pulse dose vs. continuous flow
Your prescription determines which type you need. Not sure? We’ll help you read it.
Pulse doseDelivers a burst of oxygen only when you inhale. Efficient, so units are smaller and batteries last longer.
Continuous flowDelivers a constant flow measured in liters per minute (LPM). Common for nighttime use and higher prescriptions.
Both in oneMany portables below offer both modes, so you can use pulse during the day and continuous at night.
