Answer:An average normal range of less than 120 mm hg is the standard for systolic blood pressure
Explanation:
Blood pressure is usually measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value.Systolic blood pressure is the pressure when the heart beats – while the heart muscle is contracting and pumping oxygen-rich blood into the blood vessels. It's normal range is between 90-120mmHg.
