Blood Pressure Calculator

Blood pressure is an important and vital health indicator. High blood pressure (arterial hypertension) may cause changes to blood vessels, resulting in Atherosclerosis, also known as “hardening of the arteries”. Atherosclerosis is the leading cause of stroke, heart attacks and peripheral vascular disease.

How to measure blood pressure

  • Before measurement it is necessary to calm down – sit down for 5 minutes.
  • The measurement should always be performed before eating (not on a full stomach) and every day at about the same time. Before measurement it is also not advised to drink coffee, alcohol or smoke cigarettes.
  • Cuff must be placed correctly – if measuring on the arm cuff should be placed above the elbow (elbow and cuff should be 2 fingers apart). If wrist cuff is used it should be placed one finger above the wrist,. Cuff must always be paced on the left arm as heart is on the left side of your chest. There are some rare occasions where people are born with heart on the right side of chest. In that case, cuff must be places on the right arm.
  • If you are very obese a wrist measurement is more handy.
  • It is very important to known that when performing measurement of blood pressure you need to set the meter to at least 40 mmHg higher pressure than your normal upper blood pressure is. If your normal systolic blood pressure is about 150 mmHg set your meter to least 190 mmHg. In semi-automatic blood pressure meter you can do this manually by pumping the air into cuff, on automatic meter this value is set by a button.
  • Take a few minutes between two consecutive measurements as blood vessels needs to expand properly again otherwise the second measurement will always be lower than the first.
  • Be aware that blood pressure normally fluctuates and two consecutive measurements will not show same result. That’s normal.
  • Patients with arrhythmia will usually get false results using electronic pressure gauge. The possibility of arrhythmia must be considered whenever the measurement shows “impossible” values, for example 150/135 mmHg. In that case it’s better to buy a classic mercury pressure gauges to obtain proper blood pressure value.
  • Enter your daily measurements of blood pressure into a special chart (chart usually comes with a purchase of the device). This information is very useful for your doctor and yourself.
  • For most reliable measurements it is recommended that you take your blood pressure meter to an authorized service center where they will re-calibrate it for you. Do this at least once per year.
  • If you have increased blood pressure you must act to lower it! More information on lowering blood pressure.

      Although the calculator provides useful result but the age factor is not considered. Does the age limit count?

      • March 14, 2017 at 11:41 am - Reply

        currently age factor is not considered in the calculation. Please note that for men in middle age, or about age 45 or more, high blood pressure is more common. Women are more prone to high blood pressure after the age of 65.
        Please refer to the Average Blood Pressure By Age Chart at the bottom of the article.

      Hello I am 74 years old and I am checking each day blood pressure for Doctor. I have been taking these readings at home and I was satisfied with them. Went to Pharmacy yesterday and the reading was 159/100 and pulse rate 79. How is it so different from home. The 100 is very high and what does that mean?
