abstract = {Auscultatory blood pressure measurement is the gold standard against which other non-invasive measurement devices are calibrated. However, this method systematically underestimates systolic and overestimates diastolic blood pressure. The overestimation is explained by known causes of error - primarily the stiffness of the artery and surrounding tissue. Within this context, the underestimation of systolic pressure seems paradoxical. We show that the systolic measurement is affected by changes to the arterial pressure, occurring when the blood pressure cuff is applied. The occlusion of the artery results in low pressure downstream of the cuff. Through varying parameters in a novel experimental rig, we demonstrate that the lower this downstream pressure, the greater the underestimation of the systolic pressure. Our results suggest a need for a new, more accurate measurement protocol.},
