The use of pressurized aerosol inhalers was assessed in a total of 1173 out-patients attending hospital during a three month period. One hundred and thirty-five patients already being treated with drugs by inhalation were found to have a poor inhaler technique, even though most had received instruction on how to use a pressurized aerosol and were considered to be able to use one of these devices correctly. Eighty patients who had not used an inhaler before were found to be unable to use a pressurized aerosol efficiently after reading an instruction pamphlet or having the correct use of an aerosol demonstrated to them. Fifty-one percent of patients studied were observed to have difficulty in co-ordinating aerosol release with inspiration. In 24% the release of aerosol into the mouth caused a halt of inspiration and in a further 12% the aerosol was actuated into the mouth, but inspiration was achieved through the nose with no air being drawn in through the mouth. Twelve percent of patients already being treated with inhalers actuated the aerosol on two or more occasions during one inspiration.
在为期三个月的时间里，对总共1173名到医院就诊的门诊患者使用压力定量气雾剂吸入器的情况进行了评估。发现135名已经在接受吸入药物治疗的患者吸入器使用技术欠佳，尽管大多数患者已接受过如何使用压力定量气雾剂的指导，并且被认为能够正确使用其中一种装置。80名之前未使用过吸入器的患者在阅读使用说明手册或观看气雾剂正确使用演示后，被发现无法有效地使用压力定量气雾剂。观察到51%的研究对象在协调气雾剂释放与吸气方面存在困难。24%的患者在气雾剂释放到口腔时会导致吸气中断，另有12%的患者气雾剂被喷入口腔，但通过鼻子实现了吸气，口腔未吸入空气。12%已经在使用吸入器治疗的患者在一次吸气过程中启动气雾剂两次或更多次。
