    this device is great for people with lung disorders
    This device is great for people with lung disorders like emphysema it assists with the enlargement of the lungs when the sacks are blistered or burst it can assist with the exercise program that has been set out as a task for repair of the damaged lung.

    It’s fab for asthma but device can break
    Wonderful for asthma, has really helped me improve my peak flow levels and coupled with physio helps get air into my lungs more, improving bronchiectasis and asthma. Every asthmatic should have one, and the NHS should be ashamed of themselves for not advertising its availability more. I have though been using mine for 3/4 months and the product is very plastic, the valve sticks and gives different resistances depending on how you hold it, which means I have no idea what level I’m on (I’m supposed to be on level 5) but the resistance changes every time I touch it! Still despite that, it’s well worth having. I’m just gutted I can’t afford a digital one as I should imagine they are far more reliable.

    Note from POWERbreathe Admin:
    Thank you Bartlebe for your feedback and we’re delighted the POWERbreathe Medic has helped you with your asthma. We were sorry to hear though of your experience with the valve sticking. Obviously we value your feedback, and as it’s not a problem that we’ve heard of before, we wondered if you would mind getting in touch with us at enquiries@mypowerbreathe.com so that we may help. We’ll look forward to hearing from you Bartlebe, POWERbreathe.

    Very Sceptical at first, now I must admit I can see improvements
    I was very sceptical of this device when I was first recommended it, as there are a lot of devices out there that make all sorts of fantastic claims to aid your breathing at Altitude. This is one of them that now has a growing voice from well respected high altitude mountaineers, along with having been used by numerous Everest expedition climbers and also has nearly a full page dedicated to it in the fantastic book “Mountaineering Training and preparation” a book which I can most certainly highly recommend for your training….

    …It just seems such a simple device to use that it is hard to believe that it can be this alone that is making these huge improvements in my breathing, but without a doubt I have only noticed these improvements since using the PowerBreathe.

    POWERbreathe training with a cancer patient

    The doctors were really pleased with his repeat lung function tests, some of the values had improved considerably, they felt we’ve given him the best chance possible to making it through his transplant, and feel the Powerbreathe device has been a contributing factor to this despite us only having a small window of time to work with it.

    He was using it daily from the day you dropped it off to the day he was transferred to Birmingham, and I’m confident he was going to continue with it after he left us. We had also managed to increase it up to number 4 from 1 in the few weeks he was using it.

    If he comes back to us post transplant (which I have a feeling he may) I will keep you updated on his progress and possibly we may be able to arrange a review? Although this will depend very much on if he returns to us or goes straight home.
    Many thanks for everything you did to help us in his management.

The standard unit used to measure breathing resistance is cmH20, which is short for “Centimetres of water“.

This table shows how each device in the Classic series (Light, Medium & Heavy) compares to one another. The levels 1-9 are all manually adjustable on the device at any time, and you should increase the level from 1 through to 9, over time as your breathing strength improves.

Centimeters of Water is a unit used to measure pressure on a small scale. It refers to how much pressure is needed to move a 1cm column of water.

If required, there is a much more technical explanation available here:

There are no safety reasons for preventing young children (above 7 years of age) from using POWERbreathe. However, the following factors may affect their ability to use the device effectively: 

  • They must be able to fit the mouthpiece in their mouth. The POWERbreathe Plus mouthpiece is smaller and therefore more suited to children. 
  • They must be old enough to understand how to effectively perform the breathing exercises. 
  • They must have the motivation themselves or the parental encouragement to ensure that they continue to perform the exercises. 
  • They should only use POWERbreathe under the supervision of an adult.

Inspiratory muscle training has been most widely used in patients with COPD. IMT is particularly helpful in this patient group, as they have primary weakness of their inspiratory muscles.
