Hi , and thanks for your post.
You've posted a good question about the AirPhysio device - in fact, others in the community have also asked questions about this device.
The device you are referring to (an AirPhysio), is an adjunct device that may be used to help patients clear their airways of mucus.
This adjunct falls into the category of positive expiratory pressure (PEP) devices. From my experience, many patients do well using the device, but it may not be helpful for everyone.
I thought you might gain some additional insight for this type of therapy from this article on that very topic: https://copd.net/living/strategies-improving-cough/. I do hope you find this to be helpful information.
I would also suggest you discuss this type of therapy with your physician to determine if this is suitable for your particular condition.
Earlier in my response, I mentioned that other community members showed an interest in this particular device. If you wanted to look over their conversations (and replies), here is the link, for your convenience: https://copd.net/?s=airphysio.
I am hopeful this is the information you are looking for and it addresses your expressed concern.
Wishing you well,
