MAP = DBP + 1/3(SBP - DBP)
About
Mean arterial pressure (MAP) is the average pressure in a patient's arteries during one cardiac cycle and is considered a better indicator of organ perfusion than SBP alone.
Clinical Use
Target MAP >=65 mmHg in septic shock resuscitation. May be inaccurate at very high heart rates or severe arrhythmia.
