To ensure reliable values, two measurements should be taken over a span of five minutes and then the average of the two readings calculated. Higher levels may be a sign of potentially harmful high blood pressure: 159/99 is considered slightly high blood pressure and levels over 180/110 are considered to be severe high blood pressure.īlood pressure should be measured in a resting state, with the arm positioned roughly at the same height as the heart. Up to 129/84 is considered normal elevated blood pressure up to 139/89 is still considered to be within the normal range. Ideally, blood circulates at a maximum pressure of 120 over 80 mmHg. Diastolic blood pressure is the remaining pressure during the relaxation phase of the heart. There are two blood pressure readings: systolic blood pressure measures the maximum pressure generated during the contraction phase of the left ventricle of the heart. 1 mmHg is equivalent to a pressure of about 133 pascal or 0.00133 bar.
