The Mean Arterial Press calculator compute the mean arterial pressure based on the diastolic pressure and the pulse pressure. /attachments/f10687ee-d5bd-11e3-b7aa-bc764e2038f2/MeanArterialPressureMAP-illustration.png

INSTRUCTIONS: Choose units and enter the following:

(DP) Diastolic Blood Pressure
(SP) Systolic Blood Pressure

Mean Arterial Pressure (MAP): The mean arterial pressure and pulse pressure are returned in millimeters of mercury (mmHg). However, these can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The Mean Arterial Pressure (MAP) is a term used in medicine to describe an average blood pressure in an individual. It is defined as the average arterial pressure during a single cardiac cycle.

`MAP = DP+(SP -DP)/3`

Where:

MAP = Mean Arterial Pressure
DP = Diastolic Blood Pressure
SP = Systolic Blood Pressure

The formula for pulse pressure is:

PP = SP - BP

where:

PP = Pulse Pressure
DP = Diastolic Blood Pressure
SP = Systolic Blood Pressure

MAP is considered to be the perfusion pressure seen by organs in the body. It is believed that a MAP that is greater than 60 mmHg is enough to sustain the organs of the average person. MAP is normally between 70 to 110 mmHg If the MAP falls below this number for an appreciable time, vital organs will not get enough Oxygen perfusion, and will become ischemic.
