AN AUTOMATIC SYSTEM FOR THE INDIRECT DETERMINATION AND RECORDING OF HUMAN ARTERIAL BLOOD PRESSURE.

Abstract

An automatic system for the indirect determination of human arterial blood pressure, as used in the Biodynamics Branch, USAF School of Aerospace Medicine, is described and compared with direct methods of measurement. The pressures recorded from the brachial artery by this system are not significantly different from direct measurements of arterial pressure obtained simultaneously. This degree of accuracy is probably related, in part, to the placement of the microphone under the upper half of the blood pressure cuff. With proper positioning of the microphone and the appropriate use of filters, the system will produce records free of artifact in the presence of environmental noise and vibration. This capability makes it useful in dynamic environments where the determination of arterial blood pressure is necessary. (Author)
