Blood Pressure Basics

Blood pressure is the pressure of the blood in the arteries as it is pumped around the body by the heart. When your heart beats, it contracts and pushes blood through the arteries to the rest of your body. This force creates pressure on the arteries. Blood pressure is recorded as two numbers— the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats). The unit which measures this is called Sphygmomanometer.

Monitoring blood pressure at home is important for many people, especially if you have high blood pressure. Blood pressure does not stay the same all the time. It changes to meet your body’s needs. It is affected by various factors including body position, breathing or emotional state, exercise and sleep. It is best to measure blood pressure when you are relaxed and sitting or lying down.

Classification of blood pressure for adults (18 years and older)

• Systolic (mm Hg) Diastolic (mm Hg)
  
• Hypotension < 90 < 60
  
• Desired 90–119 60–79
  
• Prehypertension 120–139 80–89
  
• Stage 1 Hypertension 140–159 90–99
  
• Stage 2 Hypertension 160–179 100–109
  
• Hypertensive Crisis ≥ 180 ≥ 110
  

High blood pressure (hypertension) can lead to serious problems like heart attack, stroke or kidney disease. High blood pressure usually does not have any symptoms, so you need to have your blood pressure checked regularly.
