The number which has been once used before is not used.

In a the most basic sense, blood pressure is a way of measuring how much force is being exerted on the walls of your blood vessels (artery) as blood flows through them. Systolic is the pressure exerted as your heart contracts or beats. This is measured as your heart sends a surge of blood through the vessels. A reading of less than120 mm Hg is considered normal. Diastolic is the pressure exerted when your heart relaxes in between heartbeats in the arteries. A reading of less than 80 mm Hg is considered normal.

According to American Heart Association, blood presure should normally be less than 120/80 mm Hg for an adult. Blood pressure that stays between 120-139/80-89 is considered prehypertension and above this level (140/90 mm Hg or higher) is considered high (hypertension).
*Your doctor should evaluate unusually low readings.
