family member

One of my family members has copd along with liver problems and next to none,white blood cells. He is obviously very ill. Alot of the time he is outta breath and coughs to the point of almost passing out.He has nosebleds  sometimes after coughing that hard and has been vomiting blood(How much im not sure) is this related to his copd or other health problems that ive mentioned or could this just be from the pressure of the etreme coughing?He does"t say to much to me about all his health problems but this has become very alarming.
