Hi Karl, In answer to your question about having trouble sleeping with oxygen, I have not had that problem.
It makes me wonder what kind of equipment ou are using. I have an oxygen consentrater machine that I
use with 50 feet of hose and a nasal canula that goes in the nose and rope over the years. It is really very
comfortable and allows me to go anywhere in my house and out on the patio or the front porch. When I go
somewhere I have a portable machine that you fill with frozen oxygen. I am so glad that you are going to
the Medical Center and I am confident you will find a good Doctor who will help you with everything. Be
sure to let us all know the outcome. Thanks for putting me in your prayers! I can really use them. Sincerely,
