Mean arterial pressure
The mean arterial pressure (MAP) is the average over a cardiac cycle and is determined from measurements of the systolic pressure and the diastolic 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.
