HI,
I know I just posted but I had some other thoughts. I would demand that my husband get a chest and/or throat X-ray and have someone examine his throat. As I had said, we believed that the radiation had swelled his throat so much that it was extremely difficult to breath. He was prescribed steroids to reduce the swelling. I really don't want to overly alarm you, but I've been there with the heavy breathing and the complete stopping of breath for several seconds. It is incredibly nerve-racking. I just wish we had been more agressive in demanding he be checked out earlier. I think we could have avoided intensive care. Good luck.
