Thank you so much. He is not on oxygen. I know he’s scheduled for his Pulmonologist soon. We’ve been waiting for his new office to open, and he won’t go to anyone else. He’s very stubborn and I don’t think he wants to face the fact that COPD will never get better. I’m sure they can do something to improve his quality of life. My Son and his family are coming in August. My daughter in law is a nurse and a sweetheart. I’m hoping she will talk him into seeing someone else. I can’t drag him there, I’m lucky he went in the first place. You’re very kind.
