Blood pressure is a measure of the force that your heart uses to pump blood around your body. It is measured in millimeters of mercury (mmHg) and is given as two figures: systolic pressure, which is the pressure when your heart pushes blood out, and diastolic pressure, which is the pressure when your heart rests between beats. A normal blood pressure level is less than 120/80 mmHg. The five blood pressure ranges as recognized by the American Heart Association are:

• Normal: Below 120/80 mmHg
• Elevated: 120 to 129/less than 80 mmHg
• Stage 1 high blood pressure: 130 to 139/80 to 89 mmHg
• Stage 2 high blood pressure: 140 and above/90 and above mmHg
• Hypertension crisis: above 180/above 120 mmHg

It is important to note that blood pressure can vary throughout the day and can be affected by factors such as stress, exercise, and medication. If you have concerns about your blood pressure, it is recommended to consult with a healthcare professional.
