How to measure blood pressure

  • 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 advisable 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 placed 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 placed on the right arm.

  1. My blood pressure is 86/69 with heart rate of 138. No physical activity before. Just walking a little. What does this mean? I am dehydrated but not hospital worthy.

  2. My blood pressure was always 100 or below systolic and 60 or below diastolic, HR below 60. I\’m 46 years old and today my b/p is 101/75, HR 75. I know it\’s normal, but I feel the difference. I was at rest while taking my b/p, so it may very well be higher during activity. My pressure is slowly changing.

I’m a 31 year old male 5’9” tall weighed 155.6 within the hour at the emergency room (had a piece of metal in my eye) my blood pressure showed 157/98 could this have anything to do with almost dying in 2009?

    • Does your heart rate noticeably increase upon standing? Does your blood pool in your extremities? Do you get dizzy when doing basic tasks or standing up? Based on what u said d if your answer is yes to my questions, you should look Into a condition called POTS: postural orthostatic tachycardia syndrome.

    • Hello,
      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.
