An automated system for obtaining a direct measurement of total respiratory resistance (R T ) is presented. A polygraph and digital computer are used to filter and quantify the pressure and flow outputs of a forced oscillatory device to determine R T . Functional descriptions of the complete hardware system and of the computer software are included. The measurement of R T is viewed as providing a sensitive and relatively unobtrusive means for investigation of psychophysiological precipitants of subclinical variations in bronchial tone in normal S s and in S s suffering from obstructive bronchial disorders such as bronchial asthma. In addition, augmented sensory feedback of R T can be utilized in investigations of S 's ability to attain voluntary control of R T .
