Answer to Question #111137 in Physics for Bianca

Question

A sphygmomanometer is used to measure the (gauge) diastolic blood pressure in a patient's veins level with their heart. This diastolic pressure is found to be 45.0 mmHg.
What is the absolute diastolic pressure in this patient's veins ? (to 3 s.f and in kPa)
(Patm = 760 mmHg = 101 kPa)

Answer 1

$$P=760+45=805\ mmHg$$

$$P=\frac{101}{760}805=107\ kPa$$
