Mean Arterial Pressure and Perfusion Pressure Calculator

Calculates mean arterial pressure (MAP = DBP + 1/3 pulse pressure), cerebral perfusion pressure (CPP = MAP - ICP), and coronary perfusion pressure from blood pressure and ICP measurements for critical care management.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates mean arterial pressure (MAP = DBP + 1/3 pulse pressure), cerebral perfusion pressure (CPP = MAP - ICP), and coronary perfusion pressure from blood pressure and ICP measurements for critical care management

Each component has a specific meaning:

  • Blood pressure — The blood pressure recorded for the scenario being assessed.
  • ICP measurements — The icp measurements recorded for the scenario being assessed.

Note: Interpret the map calculator result against the thresholds and context described above.

How to Use

Enter the blood pressure, ICP measurements for the scenario you are assessing. Calculates mean arterial pressure (MAP = DBP + 1/3 pulse pressure), cerebral perfusion pressure (CPP = MAP - ICP), and coronary perfusion pressure from blood pressure and ICP measurements for critical care management. Use the map calculator result to inform your calculation.
