Blood pressure is a vital sign that is measured to assess an individual's health. It reflects the force of blood against the walls of the blood vessels as it flows through the body. Synonyms for blood pressure include arterial pressure, circulatory pressure, systemic pressure, and vascular pressure. Different instruments and techniques can be used to measure blood pressure, such as a sphygmomanometer or a digital blood pressure monitor. Normal blood pressure ranges from 90/60 to 120/80 mmHg, but can vary depending on age, activity level, and underlying medical conditions. Managing blood pressure is crucial for maintaining good health and reducing the risk of cardiovascular disease, stroke, and other health complications.
