Blood Pressure

Blood pressure is a measure of the force exerted by blood against the walls of blood vessels. It is an important indicator of overall health, as it can provide insights into the health of the heart, blood vessels, and kidneys.

Blood Pressure Measurement

Blood pressure is measured in millimeters of mercury (mm Hg). It is typically measured using a sphygmomanometer, which consists of an inflatable cuff that is wrapped around the upper arm and a manometer that measures the pressure in the cuff. The cuff is inflated until the blood flow in the artery is blocked, and then slowly deflated while listening for the Korotkoff sounds. The first Korotkoff sound is the systolic blood pressure, which is the maximum pressure in the arteries during a heartbeat. The last Korotkoff sound is the diastolic blood pressure, which is the minimum pressure in the arteries during a heartbeat.

Blood Pressure Levels

Blood pressure levels are classified as:

• Normal: Systolic blood pressure less than 120 mm Hg and diastolic blood pressure less than 80 mm Hg
• Elevated: Systolic blood pressure between 120 and 129 mm Hg and diastolic blood pressure less than 80 mm Hg
• Stage 1 hypertension: Systolic blood pressure between 130 and 139 mm Hg or diastolic blood pressure between 80 and 89 mm Hg
• Stage 2 hypertension: Systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher

Causes of High Blood Pressure

High blood pressure, also known as hypertension, is a common condition that affects millions of people worldwide. The exact cause of hypertension is often unknown, but several factors can contribute to its development, including:

• Obesity
• Lack of physical activity
