A member asked:

What happens next after a lung function test is fine but have shortness of breath?

EKG +/- ABG: If your lung function is normal by Pulmonary Function Testing then I would consider repeating the testing in 6 months. In the meantime, I would consider checking and arterial blood gas to see what your oxygen and carbon dioxide levels are. I would also get an EKG to assess your cardiac function.
