I had that pulmonary lung function test approx. 3 yrs. ago. They did spray in something that was potentially supposed to help with lung functioning. My understand was that at that time they didn't see a big difference. I'm not sure if it was Albuterol. I should see if my Pulmonologist can review those results with me. I'd hate to have to take another of those tests. I found it pretty exhausting, since they kept pushing me to try harder, try harder, but maybe it would be worth it.
