What is the blood pressure of a person measured in?

Blood pressure is measured in millimeters of mercury (mmHg) and usually expressed as “systolic pressure over diastolic pressure” (e.g. “120 over 80”).

What is the first blood pressure reading?

A blood pressure reading consists of two values. The first (and higher) value is the systolic blood pressure. It describes the pressure when pumping blood from the heart into the body. Theis contraction of the heart muscle is called systole or cardiac output phase.

Why is systolic blood pressure higher than diastolic blood pressure?

The systolic blood pressure is higher than the diastolic because the pressure to pump the blood away from the heart is greater than the pressure in the relaxation phase which is also called diastole or filling phase. Accordingly, the diastolic blood pressure is measured when the heart relaxes and the pressure subsides.

How to measure blood pressure?

Before measuring your blood pressure, take a break of at least three to five minutes. Sit on a chair and avoid any effort, as the blood pressure can otherwise increase. Apply your blood pressure monitor on one of your arms (but always use the same arm). Rest your forearm loosly on a table top and start measuring.

When is diastolic blood pressure measured?

Accordingly, the diastolic blood pressure is measured when the heart relaxes and the pressure subsides. During the relaxation phase the blood is sucked into the heart and the heart muscle is expanded.

Why is blood pressure reading higher at the doctor?

What’s more, readings at the doctor’s office can occasionally be higher due to nervosity, an effect called white coat hypertension.
