Thank you. There's a lot of things to know when traveling, isn't there? We get the doctor's prescription, Delta's pre-approval (which is done through OxygenToGo) and one trip we had to bring three 16-cell double batteries with us. He only needed one, but the rules are the rules. An agent at MSP suggested we get the TSA pre-approval, which we did. Carrying along his CPAP, hearing aids, Inogen (batteries, not attached), Vibralung, oximeter, BP machine, inhalers, thermometer, meds, etc. is like a portable clinic. LOL
I recently put in an appt request to Mayo for him to be seen by a pulmonologist, since we don't have one around here. We have nothing against his small town doctor or the Veteran's clinic, but I would feel better with another opinion on what we could be doing better.
Your link is a helpful tool. Thanks again!
