Blood pressure (BP) is the pressure or resistance that exists in the walls of the blood vessels and heart. A circadian rhythm of pumping of the heart that results in repetitive pressure is called Blood pressure. Systolic Blood pressure is the maximum pressure in one heartbeat and Diastolic Blood Pressure is the minimum pressure in two heartbeats in the cardiac cycle. Many physiological factors which affect blood pressure in a normal individual are called Blood Pressure variability. This article aimed to overview the blood pressure variability and its significance. We concluded that the blood pressure can vary according to the position of the patient, the arm which is used for taking blood pressure should be considered for routine clinical practice.
