@JanetWendl--I would have to recommend you to Keene on the issue of swimming as she teaches it...or some form or it...reach out for her for that..have a breathe easy day

Never alone. Or...
We have hot tub that is great for a few minutes and get a little exercise, very little in my case...

Lyn Cole who sometimes posts here has swum for years, using a float device to bring her O2 along with her. Many people leave their O2 containers on the side of the pool and use a long hose; if you stay in the near lane, that works well and doesn't get in someone else's way.

Do not swim

Bought a pool, only went in it once so far and enjoyed it very much. It has been so hot out, that it takes my breath away to walk out the door. I am going to either get up early or wait til evening and use it more often to exercise in. I did not use my oxygen, but I am going to try that.
