Re: Please help. Gasping for air at night.
Hi, to answer your question about what the test involves, I had a test for asthma in 2015, which involved blowing really hard into a nebulizer type of machine that measures lung function while the nurse counted to a certain number. Then she showed me how to use a puffer spray after which my lung function was measured again. I had to do this several times and she noted the before and after numbers and after the test she was able to tell me that I didn't have asthma. The complete test took about 45 mins. Hope that helps.
ISB ☺
