Question
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
102 mmHg
systolic blood pressure Pgauge
= 0.102 m, a normal systolic reading. What is the gauge
in pascals? The density of mercury is
h
p = 13.6 x 103 kg/m³ and the ambient pressure is Po
1.01 x 105 Pa.
