7 errors, due to which the tonometer overestimates the pressure values

7 errors, due to which the tonometer overestimates the pressure values

One of the main recommendations that doctors give patients is to constantly monitor their blood pressure. Cardiovascular diseases are the leading cause of death in the world, and monitoring of pressure helps to notice a deterioration in a person’s condition. However, when measuring pressure by a home tonometer, people make a lot of mistakes. If you determine the blood pressure correctly, and also monitor how the doctor does, you can avoid, for example, unnecessary medicinal purposes. Here are seven tips from the American Heart Association.

  • Visit the toilet before measuring. A complete bladder adds 10-15 points to the blood pressure.
  • The chair on which you sit should provide full back support, and the legs should stand on the floor or a special bench, rather than hang in the air. Otherwise, the tonometer will show 6-10 points more than necessary.
  • Do not cross your legs – this action also adds “glasses” to the pressure indicator (from 2 to 8).
  • The arm on which the cuff is located should rest on the armrest. If it is hanging along the body or you are forced to keep it on weight, the blood pressure indicator can become higher by 10 points.
  • The cuff must be worn on the bare hand. Clothing between the arm and the cuff adds to the indicators from 5 to 50 points.
  • The size of the cuff is also important. The pressure can be 2-10 points higher than in reality, if the cuff is too small.
  • During the measurements it is better to remain silent and try not to move. The conversation also adds up to 10 points to the pressure indicators.
