Learn More About Portable Oxygen Concentrators Continuous FlowOut of the two main types of oxygen therapy, continuous flow and pulse dose, continuous flow is more for those who plan on using oxygen mainly while sitting still. If you need oxygen therapy while sleeping, this is likely the dosage type you will need.
Continuous flow does just as the name describes – it's a constant oxygen flow. It flows at the same rate, no matter how many breaths you take or the size of your breaths. Just because the dosage says “2 LPM” doesn't mean you're breathing 2 liters of oxygen during a minute. Some of it is wasted, but the same flow rate is when needed.
Home oxygen concentrators exclusively use continuous flow oxygen, because you aren't doing anything that would cause your breath rate to change. Home oxygen concentrators can only run-on AC power, which means you won't be going anywhere while using it. If you sit down or lie to sleep, continuous flow may be sufficient unless your doctor determines otherwise.
It ultimately comes down to which dosage setting type works best for your health and lifestyle. You can decide on this with your doctor to pick out a suitable oxygen concentrator model for you.
