Measurement of Diastolic Blood Pressure by Palpation

Abstract
THE purpose of this paper is to reawaken interest in a long neglected simple tool in physical diagnosis and to provide graphic evidence of the phenomenon involved. When the examiner palpates the brachial artery while a sphygomomanometer cuff is being deflated, a peculiar tactile sensation becomes evident as the cuff pressure approaches the diastolic blood pressure. The sensation abruptly disappears when the pressure within the cuff falls below the diastolic level. The sequence is reversed when palpation is performed during inflation of the cuff. This phenomenon has been known since the early years of the century1 , 2 and has been described . . .
