My husband has had a flare since October. He has almost no coughing and never has coughed up mucus. He has emphysema . He's been on steroids almost nonstop since this started. And antibiotics off and on. We thought he was a getting a little better. But his oxygen level last night was 69 when he got into bed. It didn't stay there long . And did go up to 92. he is on oxygen 24/7 and was on 4.5 liters when this happened. It usually goes down to high 70's and works it way up. Sorry I'm so long winded. What I wanted to know if any of you have tried the massager on your back to help break up mucus? He has had a chest x-ray , blood work and a CT scan in the last three weeks. He tries to make himself cough but he usually doesn't cough up anything. We don't know if with emphysema you are to make yourself cough. he has the flutter thing. he doesn't really cough after using that.
