Question

A doctor records the blood pressure of a person as 140/90 Hg. What does it indicate? What instrument is used to measure the blood pressure?

Answer 1

Blood pressure:

• Blood pressure can be defined as the pressure at which blood flows through the blood vessels.

Measurement of blood pressure:

• The normal human blood pressure is represented as 120/80 Hg.
• Any blood pressure values below and above 120/80 Hg are not desirable.
• Blood pressure readings of 140/90 Hg represent high blood pressure, also termed hypertension.
• There is a specific instrument to measure blood pressure, and it is called a sphygmomanometer.

Thus, high blood pressure of 140/90 Hg is hazardous for human health.
