After spirometry was conducted the subjects used the inhaler; they were unaware that their technique of use was being observed. Only 10.8% performed correctly all 11 maneuvers suggested for the proper use of the inhalers, and 24.7% failed to perform more than 5 satisfactorily. There were significant differences in performance according to referral diagnosis (chronic obstructive lung disease v. asthma) and regularity of use of inhalers. ER -
