Once he is having trouble getting enough air to
carry on a conversation
, then he needs to
quit, rest, and then try again. It's a long process, but it does help to
build the body back up from where he is at this point.
Now, for the worst part....if he smokes, he needs to
quit, and he needs to
be on a strict, low sodium diet, and if he has any extra weight on, he needs to
lose it, using a diet of veggies, fruit, and lean meat and poultry. NO junk food.
