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 you are sleeping, this is likely the dosage type you will need.
Continuous flow does just as the name describes – it's a flow of continuous oxygen. 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 actually breathing 2 liters of oxygen during a minute. Some of it is wasted, but the same flow rate is there when you need it.
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. Sitting down, or lying down 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 your lifestyle. You can decide on this with your doctor, so you can pick out the right oxygen concentrator model for you.
