what is the normal range for systolic blood pressure in the adult patient
The low point is referred to as diastole and occurs when the ventricles relax and minimal pressure is exerted against the vessel wall. A normal blood pressure for a healthy adult ranges from 90 to 120 mm Hg systolic and from 60 to 80 mm Hg diastolic. Under normal circumstances, blood volume remains constant at 5,000 mL.
