There are many good materials that you and your family can read to find out more about COPD & how to help optimize your dad's lungs & health.
One of the most important things is for him to QUIT SMOKING & avoid all lung irritants.
You can get great free info from www.NationalJewish.org, particularly their MedFacts and Understanding series. You can also get info mailed to you by calling your local branch of the American Lung Association.
It would be good to ask his doctor if he could enroll in a pulmonary rehabilitation program to help learn more about appropriate exertion & how to optimize his treatment program.
Your dad's doctor should be asked about SPECIFIC info about HIS condition. In particular, the doctor could evaluate him to determine whether he needs supplemental oxygen--at least, upon exertion and while sleeping.
Best of luck! Your dad is lucky you are such a loving and caring daughter.
Aloha,

It is very difficult to tell you what to expect because every person is affected so differently by chronic obstructive pulmonary disease (COPD). What can be said is that your father will advance from one stage of COPD to the next stage at a faster rate as long as he continues to smoke. This will generally decrease his quality of life and his life expectancy. The most important thing that your father can do to help himself is to quit smoking. It is not possible to say that this will stop his progression to the next stage of COPD, but it will slow down the rate of progression.
To help your father to quit smoking, you may want to look at our Just Quit Online program at http://www.nationaljewish.org. Also check with your father
