Your blood pressure varies from day to day, even moment to moment. Blood pressure is measured in ‘mmHg’, which refers to millimetres of mercury. The two measurements are input in millimeters of mercury (mmHg), the first being the maximum. diastolic pressure – the pressure when your heart rests between beatsįor example, if your blood pressure is '140 over 90' or 140/90mmHg, it means you have a systolic pressure of 140mmHg and a diastolic pressure of 90mmHg. It is given as 2 figures highest over lowest or systolic over diastolic. The blood pressure calculator uses the measured values of systolic and diastolic pressure to estimate, based on formulas, the mean arterial pressure (MAP), the blood pressure status (ranging from normal, pre-hypertension to hypertension stage II).systolic pressure – the pressure when your heart pushes blood out.How is blood pressure measured?īlood pressure is measured in millimetres of mercury (mmHg) and is given as 2 figures: For example, your numbers may be '120 over 80' or written as 120/80.
