Arterial pressure is the input pressure for organ perfusion
Mean arterial pressure (MAP) is the best physiologic estimate of perfusion pressure
MAP is less subject to measurement variability than SBP and DBP
MAP remains relatively constant when measured at different sites throughout the arterial circuit
MAP of 60 mmHg is considered the autoregulatory threshold below which perfusion becomes compromised
Goal: maintain MAP > 65 mmHg
There is no proven value to achieving a MAP higher that 65 mmHg. In fact, there is some literature to support that if you try and drive the MAP higher, patients do worse
