The characteristics of pressure-wave propagation through a brachial artery simulated by a thin walled silicone rubber-tube, a part of which was compressed externaly by pneumatic cuff, was studied experimentally when the pressure at the proximal end of the tube was given as a boundary condition. The amplitude and the shape of the pressure-waves traveling downstream through the arteries proximal and distal to the cuff strongly depend on the artery length between the aorta and the cuff. Only when the length is short enough, the magnitude of the cuff pressure when the first and the last Korotkoff sound are monitored can be closely related to the systolic and the diastolic pressure at the artery proximal end (the aorta pressure).
