Most pulmonary rehabilitation (PR) programs last a few months. At the end of your program, you'll undergo tests and answer questions. Some of these tests, such as exercise tests, will be the same ones you had at the start of your program.
The data gathered at the end of the program will show whether your symptoms, physical activity level, and quality of life have improved. If they have, your team will encourage you to continue your exercises, breathing strategies, and other prescribed changes on your own.
If you have little to no improvement, talk with your doctor. He or she might want to change your medical therapy. Or, your doctor might recommend more tests. These tests can show whether you have another condition that also may have to be treated to improve your breathing.
