Blood pressure
Blood pressure is the pressure exerted on arterial walls as the heart pumps blood through the body. Systolic blood pressure occurs when the heart contracts, while diastolic blood pressure is measured between heartbeats when the heart is relaxed. Taking blood pressure measurements allows healthcare providers to establish baseline readings and monitor for changes related to disease or medical treatment. Factors like age, exercise, stress, genetics, diet, smoking, and medical conditions can impact blood pressure levels.

- 3. Blood pressure (BP)is the pressure or tension exerted on the arterial walls as blood pulsates through them.
- 5. Is a pressureexerted on the arteries during the contraction phase of the heartbeat. SYSTOLIC BLOOD PRESSURE (SBP)
- 6. Is the restingpressure on the arteries as the heart relaxes between contractions. DIASTOLIC BLOOD PRESSURE (DBP)
- 10. PURPOSES OF TAKING B/P •To obtain baseline data for subsequent evaluation. • To determine haemodynamic status ( e.g. cardiac output ). • To identify and monitor changes in blood pressure resulting from disease process or medical therapy ( e.g. rapid infusion or pain ).
