I failed my pulmonary function test horribly!!! I could not inhale or exhale at a high enough rate for the machine to even register that I was breathing. I also could not hold my breaths long enough to get a reading. 3 different techs tried & nothing!!!! I'm not quite sure what this means & if anything needs to be done about it. My 30 day heart monitor should come in the mail any day now. It was supposed to be here last Saturday.
