Flexi Says: Blood pressure is read as two numbers. The first number is the systolic pressure. The systolic pressure is the pressure on the blood vessels when the heart beats. This is the time when there is the highest pressure in the arteries. The diastolic pressure, which is the second number, is when your blood pressure is lowest, when the heart is resting between beats. Healthy ranges for blood pressure are: Systolic: ~120 mm Hg Diastolic: ~80 mm Hg
