Diastolic And Systolic Blood Pressure

Blood pressure is defined as the force or pressure which is exerted by the blood on the walls of the blood vessels as it moves through them. There are two reading of blood pressure. They are:

Systolic Blood Pressure:

It is the force exerted by the blood on the walls of the blood vessels when the heart is beating.

Diastolic Blood Pressure:

It is the force exerted by the blood on the blood vessels when the heart is relaxed this means the time in between the two heart beats.

How Are Diastolic And Systolic Blood Pressures Measured?

Doctors use a machine called

Sphygmomanometer

for measuring the blood pressure of the body. This device comprises of a cuff, a valve, a gauge and a dial. In order to measure the blood pressure, cuff is wrapped around the hand and is inflated slightly.

The measurement of systolic and diastolic blood pressure is noted on the gauge attached to the cuff. The measurement of the blood pressure is written in the form of a fraction; one number at the top and the other at the bottom. Like the normal measurement of the blood pressure is 120/80.

What Are The Abnormal Levels Of Blood Pressure:

The abnormal levels of blood pressure are discussed in the chart below:

Abnormal Levels Of Blood Pressure
Type Of Abnormal Blood Pressure Top Number( Systolic Pressure) Bottom Number( Diastolic Pressure)
Prehypertension 120-139 80-89
Mild High Blood Pressure 140-159 90-99
Moderate To Severe High Blood Pressure 160 and above 100 and above
Low Blood pressure (Hypotension) Lower than 90 Lower than 25 mm. or more

Why Are The Numbers Of Blood Pressure Important?

The numbers of blood pressure are important because the higher levels of blood pressure can result in various disorders like:

  • Development of some Neurological condition
  • Cardiovascular disorder
  • Disorder in the kidneys or in the urinary system of the body
  • Development of a condition called Pre-eclampsia in pregnant women
  • Development of many psychological factors like anger, fear or stress
