在两个实验中，使用指令和反馈来评估抽吸体积的灵活性以操纵体积。此外，还检查了改变抽吸量对抽吸持续时间、抽吸峰值流量和一氧化碳（CO）增加的影响。在第一个实验中，受试者被告知要吸小、中、大三口。受试者能够准确地遵循抽吸大小说明;他们通过改变抽吸持续时间来进行不同大小的抽吸。在第二个实验中，当控制抽吸持续时间时，受试者能够通过改变抽吸强度来遵循抽吸大小说明。这两个实验表明，可以通过指令控制产生宽范围的抽吸体积，并且体积变化可以由抽吸持续时间或抽吸强度的改变引起。
In two experiments, the flexibility of puff volume was assessed using instructions and feedback to manipulate volume. Also, the effects of altered puff volume on puff duration, puff peak flow, and carbon monoxide (CO) boost were examined. In the first experiment, subjects were told to take small, medium, and large puffs. Subjects were able to accurately follow the puff size instructions; they took different-size puffs by altering their puff durations. In the second experiment, when puff duration was controlled, subjects were able to follow the puff size instructions by altering the intensity of their puffs. These two experiments demonstrated that a wide range of puff volumes can be generated by instructional control and that volume changes can result either from alterations of puff duration or of puff intensity.
