Blood pressure measurements in the conscious rat. An improved photoelectric, sphygmomanometric device.
A photoelectric device for repeated, noninvasive registration of blood pressure in the tail of the rat was built, mainly using available materials and components. A description of the measuring system is given. Comparison between blood pressure measurements performed simultaneously in the tail of the rat and intravascularly in the aorta are in good agreement.
