The best respiratory device I have found!
I need a device to assist with removing mucous from the lungs--and for this, there aren't many devices that work. The A Capella is what I was given in the hospital after hospitalization for pneumonia. However. the Flutter Valve works 100 times better--and the instructions are explicit about how to use it. If you need a device for this purpose, check with your medical provider. I highly recommend it.
