Why average multiple readings instead of using one?

Blood pressure fluctuates naturally due to stress, activity, and measurement technique, so clinicians typically recommend averaging 2-3 readings taken a minute apart for a more reliable number.

Can this diagnose hypertension?

No, this only averages the numbers you enter. Use the average with the blood pressure category calculator, and consult a healthcare provider for diagnosis.

Average Blood Pressure Calculator

Average three separate systolic and diastolic blood pressure readings to get a more reliable estimate than a single measurement, since blood pressure naturally fluctuates throughout the day and even between consecutive readings.
