I suffer from some minor joint problems with my right knee, hip, and shoulder, as well as a mild form of Chronic Obstructive Pulmonary Disease (COPD).

Exercising in a pool is recommended for those with joint problems, but COPD requires that I be connected to a 2L source of oxygen when exercising or sleeping.

Is there a manufacturer who offers equipment that would provide me with a source of oxygen while exercising in a pool, or for that matter at the beach? I have an Invacare Self Fill Unit for filling tanks, etc.

I haven't had any luck with my requests at the hospital or with manufacturers of medical oxygen equipment. Hopefully you will have a suggestion.

Thank you.
