A series of experiments was conducted to examine the effect of regional peripheral resistance on Korotkoff sound. Peripheral resistance distal to the sphygmomanometric cuff was altered through induction of ischemia in the arm. Maintenance of a cuff pressure, 20 mmHg above the systolic pressure, for periods of 0 (Control), 30, 60,and 90 seconds induced various levels of ischemia. Immediately following each period, Korotkoff sounds were recorded as a function of cuff pressure. Systolic and diastolic pressures were measured in the standard fashion prior to and well after the end of each experiment. Data were obtained on eleven human subjects ranging in age from 18 to 88 years, with a mean age of 34 years. The apparatus employed for the recording of the Korotkoff sound, consisted of a cuff, and a standard stethoscope coupled to a microphone. After amplification, the Korotkoff sounds were recorded on an FM tape recorder.
