Use our blood pressure chart to learn what your blood pressure levels and numbers mean, including normal blood pressure and the difference between systolic and diastolic. In a normal adult blood pressure of 120/80, diastole is the bottom (second) number 1.
Understanding the Context
Calculate arterial blood pressure (BP) by multiplying cardiac output (CO) by vascular resistance (VR): (Ref 1) BP= CO x VR. Cardiac output is the rate of blood flow produced by the heart. The blood pressure equation consists of blood pressure, the stroke volume equation, and the cardiac volume equation. Learn what they mean, how they are calculated and their use.

Key Insights
Blood pressure is usually expressed in terms of the systolic pressure (maximum pressure during one heartbeat) over diastolic pressure (minimum pressure between heartbeats) in the cardiac cycle. Blood pressure is the pressure of circulating blood on the walls of the blood vessels. It is usually determined by two values: Diastolic blood pressure — the minimum BP in between two heartbeats, when the heart is at rest. Blood pressure is determined by the equation: Blood Pressure = Cardiac Output × Total Peripheral Resistance. This fundamental relationship explains how blood...

Learn how blood pressure is measured. What is blood pressure? Blood pressure is a measure of the force of blood inside your arteries. Each time your heart beats, it pumps blood into a large artery called your aorta. This happens 60 to 100 times a minute, 24 hours a day. Where blood pressure is discussed in textbooks, it is usually described in terms of the relationship between flow and resistance, crudely approximated using Ohm's law (Q=∆P/R), which describes the relationships of pressure resistance and flow: Pressure is the product of resistance and flow:
