Mean arterial pressure
Mean Arterial Pressure
Mean arterial pressure (MAP) is a term used in medicine to describe the average blood pressure in an individual's arteries during one cardiac cycle. It is considered a crucial indicator of blood flow, organ perfusion, and tissue perfusion.
Pronunciation
Mean Arterial Pressure: /miːn ɑːrˈtɪərɪəl ˈprɛʃər/
Etymology
The term "Mean Arterial Pressure" is derived from the English language. "Mean" is from the Old English 'gemǣne', meaning 'common or shared', "Arterial" is from the Latin 'arteria', meaning 'windpipe, artery', and "Pressure" is from the Latin 'pressura', meaning 'action of pressing'.
Definition
Mean arterial pressure (MAP) is defined as the average pressure in a patient's arteries during one cardiac cycle. It is calculated using the formula: MAP = [(2 x diastolic)+systolic] / 3.
Related Terms
- Blood Pressure: The pressure of the blood in the circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
- Cardiac Cycle: The sequence of events that occur when the heart beats. It includes the diastole, systolic, and atrial systole.
- Diastolic Pressure: The blood pressure during the part of the heartbeat when the heart's ventricles are relaxing.
- Systolic Pressure: The blood pressure during the part of the heartbeat when the heart's ventricles are contracting and the blood is being pushed out into the arteries.
- Perfusion: The process of a body delivering blood to a capillary bed in its biological tissue.
