View All. For a long time, normal blood pressure was defined as 120/80 mm Hg (systolic/diastolic). Recently, however, the American Heart Association revised its guidelines about what an optimal blood pressure range is, and when blood pressure is considered too high or too low. While 120/80 used to be considered normal, the new guidelines define three levels of abnormal blood pressure values. 120-139 / 80-89 is now considered to be âprehypertensionâ (or âalmost high blood pressure), and doctors are watching blood pressures in this range more carefully than in the past.
These values for the 10-12 years age group are 114-127 (systolic) and 77-83 (diastolic). Normal Blood Pressure Range for Adults. The normal blood pressure for adults needs to be less than 120 mmHg in the systole phase while the value for the blood pressure in the diastolic phase should be less than 80 mmHg.Normal Blood Pressure Range for Elderly. The values of ideal blood pressure change with age.hese values for the 10-12 years age group are 114-127 (systolic) and 77-83 (diastolic). Normal Blood Pressure Range for Adults. The normal blood pressure for adults needs to be less than 120 mmHg in the systole phase while the value for the blood pressure in the diastolic phase should be less than 80 mmHg.
