FYI the doctor has to prescribe the rehab for insurance coverage. In addition if you’re on medicare you only get so many weeks of rehab covered. I have had pulmonary rehab on two separate occasions in a two year period. It consisted of watching several videos of pulmonary (issues) on breathing properly to get the best use of my lungs. I did some light weight training, walking and biking (at a snails pace) to start with so they could measure where I’m at in my lung capacity. From there we progressed in intensity to get me to my optimum breathing without O2 (in my particular case). Several people did similar rehab routines but with O2. Upon completion of my routine they would use a percussion tool to vibrate my back and loosen the sputum. I found this to be quite helpful. The reason I had stopped the first time is that I fractured a rib coughing and it was to painful to do almost anything since I coughed so much. It took months for it to heal where I could go back to rehab. On the second time around they used the hand cupping method on my back to loosen the sputum, which (I think) wasn’t quite as effective as the percussion tool. They were somewhat apprehensive about me pushing myself to the limits to where I’d get winded and start coughing. I understand that and that was why I discontinued my rehab for the gym. I saw a few patients who started rehab on my first time around and they could barely walk even with the assistance of a walker. When I went back the second time I was astounded at how much better the patients were and the progression they made. Where I live there aren’t many pulmonary rehab places around and the closest location was a hospital with a waiting period to even get on the list for rehab, once on the list there was a waiting period before actually being called for treatment. Talking with former patients of that hospital rehab, they told me it was a group instead of individual rehab and it consisted mainly of stretching and a little bit of useless exercises. I happened to find a private one near me that just opened for business, visited it and called my rehab connection at my pulmonary clinic to get the business approved for treatment and referral. Lucky me huh? I have since continued on by pushing myself to go back to the fitness club for working out, as the rehab posed not enough challenge for me. Bottom line, I recommend doing some rehab whether it be clinical or on your own (just be aware of your limits). I use my portable oxygen tank to help me recover between sets on my weight lifting and have made acquaintances just out of the curiosity of me working out with the aid of oxygen, and my recurring cough when winded. They are truly concerned for my well being, yet supportive of my regimen after finding out my condition. Hope that helps in explaining my experience with pulmonary rehab.
