Blood Flow and Pressure Telemetry.
Abstract
The past year's research concluded a two-year study of the renal hemodynamic adjustments of the military working dog in response to a variety of environmentally-induced stimuli chosen to produce both physical and emotional responses. The vascular reactivity of the kidney was the indicator of the relative amount of psychophysiological stress inherent in a given situation. Hemodynamic responses of the kidney were studied, using an implanted blood pressure and flow telemetry system activated by a radio frequency-sensitive switch. Renal blood flow was obtained by a pulsed ultrasonic flow detection system with the flow transducer cuff placed on the left renal artery, and aortic blood pressure was obtained from an intravascular pressure transducer implanted immediately below the left renal artery bifurcation.
