A sphygmomanometer is a device used to measure blood pressure, typically consisting of an inflatable cuff and a manometer used to measure air pressure in the cuff. In a mercury sphygmomanometer, blood pressure is related to the difference in heights between two columns of mercury. The mercury sphygmomanometer shown in the figure below contains air at the cuff pressure P. Po The difference in mercury heights between the left tube and the right tube is h = 114 mmHg = 0.114 m, a normal systolic reading. What is the gauge systolic blood pressure Pgauge in pascals? The density of mercury is p = 13.6 x 10³ kg/m³ and the ambient pressure is P = 1.01 x 105 Pa.
