Abstract

In 1885, Marey suggested that the wall tension of a blood vessel is zero when the transmural pressure is zero. More precisely, buckling, defined as the point of collapse of the vessel, occurs when near the zero transmural pressure. This concept of buckling is applied to measure beat to beat blood pressure. Cuff oscillations were used as an indication of arterial volume and a feedback circuit was employed to compute the derivative of arterial volume with respect to cuff pressure on a beat to beat basis. A sample record of the regulated cuff pressure indicates the continuous tracking of pressure of a subject at rest. Another advantage of this approach is that cessation of blood flow is not required.
