Blood Pressure Calculator - High and Low Blood Pressure Numbers (2024)

The readings should be taken when a person is in a relaxed and resting state. The test should be repeated at different intervals of the day or over a few days until similar values are consistently obtained. Measurement should be avoided immediately after exercise or a meal, as blood pressure may be high at these times.

Beware also of the White Coat Syndrome! It is a condition in which some people blood pressure is high in a doctor’s office but normal at home. This may be because of anxiety and stress. White Coat Syndrome may lead to misdiagnosis and unnecessary treatment.

Unsure about what your blood pressure numbers mean? Don't know if they indicate high blood pressureor low blood pressure?

If you have recently checked your blood pressure and know the top and bottom numbers, we suggest that you key the numbers in the box below and instantly get an idea whether it is normal or abnormal. The calculator evaluates your blood pressure by comparing it to the standard range for your age group, identifying any deviations from the norm. The final result will help you understand why it is important to regularly keep track of your blood pressure readings and gives tips on how to maintain a normal blood pressure.

The American Heart Association (AHA) and other medical organizations recommend that people with high blood pressure or hypertension monitor their blood pressure at home. Home monitoring(1^✔) is easy and saves both time and money and at the same time avoids white coat hypertension(2^✔) Blood pressure is a 'mathematical representation' of two forces(3^✔). The top number (systolic) is the force applied against the walls of the arteries when the heart beats and the bottom number (diastolic) is the force applied against the walls between the two beats of the heart (i.e. when heart is in a relaxed state). A blood pressure range of 110/70 to 120/80 is considered normal.

Do remember that it is important to measure the blood pressure (BP) properly for the management of hypertension(4^✔) and this may require more than one reading with the right cuff size, its correct positioning on the arm, remaining still and avoiding caffeinated drinks or smoking(5^✔). Both manual or automated blood pressure measurement requires the same precautions.

There maybe no symptoms or very subtle indicators like anxiety, excessive sweating, palpitation, fatigue, dizziness or ringing in the ear.Monitoring the blood pressure at home can prevent the complications such as heart attack and stroke associated with high blood pressure(7^✔).

• Take the right posture by sitting correctly –Sit on a dining chair rather than sofa with your back straight and supported. Keep you feet flat on the floor and not crossed. Your elbow should be supported flat on the table and the cuff should be where your mid- chest is so that it is t the same level as your heart.(11^✔)
• Bare the Armfor the Reading– Tie the cuff on the bare arm, so either take of the shirt or pull up your sleeves.
• Choose the right cuff & Tying the cuff-Depending on your arm size you could choose between small, medium and large cuff. It is best to ask the nurse or doctor what cuff size is best for your arm. The cuff should be tied snugly around your arm and two finger breadths above your elbow.(12^✔)
