Metered dose inhalers are difficult for patients to use. A device that eliminates coordination and timing of actuation may simplify the use of metered dose inhalers. This trial compared (1) number of errors made and (2) specific errors made between the conventional press and breathe metered dose inhaler (MDI) and the novel breath actuated Autohaler inhalation device in 24 subjects. We studied the use of each device in 12 patients trained and experienced in using an MDI and in 12 volunteers who had never been exposed to any inhalation device. We observed that even experienced patients continue to have difficulty with the coordination and timing of metered dose inhalers. The volunteer group had equal difficulty with both devices but it appeared that it was easier for them to learn how to use the breath actuated device than the MDI.
定量吸入器对患者来说使用困难。一种消除启动时协调和计时的装置可能会简化定量吸入器的使用。本试验比较了24名受试者使用传统按压并呼吸的定量吸入器（MDI）和新型呼吸启动的自动吸入器时（1）出现的错误数量以及（2）出现的具体错误。我们研究了12名接受过MDI使用培训且有经验的患者以及12名从未接触过任何吸入装置的志愿者对每种装置的使用情况。我们观察到，即使是有经验的患者在定量吸入器的协调和计时方面仍然存在困难。志愿者组使用两种装置时遇到的困难相同，但似乎他们学习如何使用呼吸启动装置比学习使用MDI更容易。
