WHAT IS MEAN ARTERIAL PRESSURE

(MAP)

The Mean Arterial Pressure is the average pressure forcing blood through the arteries. It is not the average of the systolic and diastolic blood pressure. It corresponds to a state of balance between the compressive and expansive forces acting on the arterial wall when there is no distension of the arterial wall, either outward or inward.

MAP is an excellent way to evaluate the stress on the walls of the vessels. It is useful to quickly evaluate excessive load on the cardiovascular system. Show the history of the MAP to your doctor may help providing more information for his reference to understand your situation.

diastolic	90	140	160
	Systolic (mmHg)

Important:

Consult your doctor on Mean Arterial Pressure.

please note:

-Hypotension value is for reference only.

-Blood pressure is considered high when either the diastolic or systolic blood pressure value exceeds normal range.

-Consult a medical professional when blood-pressure values are outside of the normal range.

OSCILLOMETRIC MEASURING METHOD

This device adopts the Oscillometric Measuring Method to provide readings of not only Diastolic and Systolic blood pressure, but also, unique, Mean Arterial Pressure. The Oscillometric Measuring Method was first described by Marey in the late 1800s, several decades before Korotkoffs description of the auscultatory method. The Oscillometric Measuring Method is a good means to determine the systolic / diastolic / mean blood pressure based on the measurement of pressure oscillation during the cuff pressure deflation phase.
