Questions as to the use of pressurized aerosol inhalers were asked of 130 persons presenting for routine pulmonary function studies who had used such a device in the previous year. 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.
针对130名前来进行常规肺功能检查且上一年使用过此类装置的人员，询问了有关使用加压气雾剂吸入器的问题。在进行肺活量测定后，受试者使用吸入器；他们并未意识到自己的使用技巧正在被观察。只有10.8%的人正确完成了为正确使用吸入器建议的所有11个动作，24.7%的人未能令人满意地完成超过5个动作。根据转诊诊断（慢性阻塞性肺疾病与哮喘）和吸入器的使用规律，在操作表现上存在显著差异。
