What is the target mean arterial pressure in post-resuscitation care?

Maintaining adequate perfusion pressure after resuscitation is essential for preserving brain and heart blood flow. The recommended target is a mean arterial pressure of at least 65 mmHg, which helps ensure sufficient cerebral and coronary perfusion when autoregulation may be impaired after cardiac arrest. Mean arterial pressure combines both systolic and diastolic pressures, giving a better sense of overall driving pressure for organs than either number alone. If MAP drops below 65, organ perfusion can decline; if it’s kept too high, there are risks from excessive vasoconstriction and increased cardiac work. The other options focus on a systolic threshold, a diastolic threshold, or an oxygen saturation goal, none of which directly represent perfusion pressure in post-resuscitation care.
