I recently took my PFT , although I changed the docotor, the PFT tech is still the same because he is used by several doctors. This tech eventhough I raised the issue with him and the doc, he still gives no more than one minutes after he gives me the inhaler to proceed with the rest of the test. I told him and asked him to wait longer and he objected saying that it wont make any difference as the albuterol acts quickly and waiting longer wont have no real bearing on the results. Is that true???
