Map Mean Arterial Pressure

These will be discussed further under the Mechanism heading of this article. This number in parentheses is the mean arterial pressure MAP. Why Use Systolic BP. MAP is influenced by cardiac output and systemic vascular resistance each of which is influenced by several variables.

Arterial Pressure

MAP is influenced by cardiac output and systemic vascular resistance each of which is influenced by several variables.

Map Mean Arterial Pressure. The normal MAP is 70100 mm Hg and a MAP of at least 60 mm Hg is necessary for adequate cerebral perfusion. These will be discussed further under the Mechanismheading of this article. Its the mean pressure of blood flow throughout the arteries of a human body.

MAP is approximately equal to the product of CO and SVR as expressed mathematically by the following equation. Sheldon Magder MD is a critical care physician at Royal Victoria Hospital and a professor in the Department of Physiology at McGill. Mean arterial pressure MAP is used to describe average blood pressure in an individual in a single cardiac cycle.

During the procedure the women were in the sitting position with their arms supported at. As it turns out numbers that significantly deviate from this normal range will have a marked effect on organs that cannot afford to have poor perfusion even if for a few minutes. The arterial baroreflex is a key regulator of MAP.
