Systolic Pressure Normal Range. Recurrent stroke prevention guidelines suggest that larger reductions in systolic blood pressure (sbp) are positively associated with a greater reduction in the risk of recurrent stroke and define an sbp level of less than 120 mm hg as normal. Adults between 2001 and 2008, the average reading was 122/71 mm hg.

When blood pressure readings consistently range from 120 to 129 systolic and less than 80 mm hg diastolic, it is known as elevated blood pressure. People with elevated blood pressure are at risk of high blood pressure unless steps are taken to control it. Nevertheless, it is important to generally consider that the range of normal pulmonary artery systolic pressure is wider than previously thought.
