COPD and heartfaiure? My dad had COPD and heartfailure. The last few nights hes really gone down hill. When i got there last night he was asleep, then i notice he as turning blue and his right ear had gone black. I managed to call the emergancy doctor out to see him. The doctor gave him 5 steriodes there and then. My dad will not go into hospital. We do everything at home for him. The doctor has said it will be a painless for him and will go in his sleep, but at the moment his in so much pain. This COPD is so up and down, i went and got his prescription out this morning and when i got back he was sitting up eating strawberries looking alot better. No-dout he will go back down later on to night. He did mention pins and needles in his left hand that would'nt go away.  
Has anybody got any answers that can educate me on this situation. I would appreciate thank-you.

Summarized question: Could you please provide me more information on the symptoms and cause of Chronic obstructive pulmonary disease (COPD) and heart failure?
