What is your opinion on a plus concentrator vs a continuous flow concentrator?

I’m thinking of getting a plus concentrator but have always had continuous flow. I’m fairly active and would like the weight of one and the ability to move around easier. I have end stage (hate that name) COPD and my flow rate is 2 liters.

    Hi BobMc, and thanks for your post here in our Q & A section. I see my colleague, Lyn, has provided you with a comprehensive view of the two different types of concentrators (continuous versus pulse flow).

    I think your view of choosing a concentrator that facilitates you moving around easier is a good one. Ultimately of course, the choice will be yours. In order to be thorough, I too, think you may want to discuss this further with your physician.

    Either way, please do check back and let us know how this all turns out for you.
    Good luck!

    Hi BobMc – That’s a great question! It sounds like you’re familiar with a continuous flow concentrator, having been on one.

    One of the things many people like about pulse dose devices is the size. The technology required to operate continuous flow dictates they be bigger and heavier.

    The deliver O2 to meet the respiratory needs and breath rate of the user. Due to technology wasted oxygen is minimized in a pulse dose device compared to a continuous flow device.

    The settings vary by manufacturer, but usually they’re enough alike that you can find one you feel is right for you.

    It’s important to note that clinical studies have shown them to be effective and comparable. Most importantly, they allow you to be more active due to the size and weight.

    I recommend you speak to you doctor about it and perhaps trial one if it’s possible. I wish you the best in finding what works for you.

    Best, Lyn (site moderator)
