What do blood pressure measurements mean?

  • Blood pressure is measured with two numbers (e.g. 124/84 millimetres of mercury). Millimetres of mercury is a standardized measurement of pressure.
  • Your blood pressure is measured with a systolic number (SBP) and a diastolic number (DBP). Systolic pressure occurs when your heart contracts and is the higher of the two numbers.
  • Diastolic pressure is the lower number and it occurs when your heart relaxes and fills with blood. The higher your systolic or diastolic pressure, and the longer it stays high, the more damage there is to your blood vessels.
Your blood pressure should be less than 140/90 mmHg
If you have diabetes, you are more likely to have high blood pressure. Your blood pressure should be less than 130/80 mmHg
