I called my dad a bit ago. He is getting ready to take Shelley back to spring lake. He said that last night he was not feeling well and when the nurse came today she said that he should be wearing his oxygen. So she got it all hooked up and he is wearing oxygen. He said it does make him feel better. So he is wearing it. They are going to get ine for the bedroom too. The oxygen really will help him feel better! He will stay at Shelley's overnight tonight.
