title: Relation of puff volume to other topographical measures of smoking.
abstract: Puff volume, puff duration, interpuff interval, cigarette interval, puffing rate, and number of puffs per cigarette were recorded in eight normally smoking subjects during five daily one-hour laboratory sessions. Topographical measures showed wide variability across subjects, but measures were relatively stable within subjects. Puff volume was significantly positively correlated with puff duration for five subjects. As the cigarette was smoked, puff duration remained relatively constant, while puff volume decreased systematically and interpuff interval increased initially and then decreased.
