Good Morning Dear Dr. Andrew Rynne, I Have A Very

Good morning dear Dr. Andrew Rynne, I have a very dear neighbor who has been very ill with a lung disease. They say it is from many years of smoking, plus his daily jobs was painting houses, and bleaching driveways and homes. He is now on oxygen, his levels are sometimes 66. They say if he gets up and walks too fast he can just drop, which could be his end. They are saying there is not much they can do for him, I refuse to accept this. He is from Columbia, now lives next to me in Florida. PLease Dr. Rynne, can you advise me to help this beautiful man any way I can, we have grown so fond of him, I don't want to lose him, forget about his wife, she can never survive without him. Thank you kind sir, I look forward to your response. Christine Schiavone.
