Sperometry

One study found only 62 % of patients labelled and even treated for co ped actually had obstruction on their p f. Ts, whell so one and three people werege treated for something they didn't have. I feel like i've seen a decent amount of patients with an impressive smoking history who actually end up having no evidence of c o p d. Some studies found even after the sperometry didn't show obstruction, then four patients were still getting ed for copete a year and a half later. That is a long time to be on daily inhalers for something, again, that they don't have.
