Why MAP Matters in Clinical Practice
Mean Arterial Pressure is a critical indicator of organ perfusion and tissue oxygenation. Unlike systolic or diastolic blood pressure alone, MAP represents the average arterial pressure throughout the cardiac cycle.
Organ Perfusion Indicator
MAP represents the average arterial pressure during the cardiac cycle and is a better indicator of organ perfusion than systolic or diastolic BP alone.
Better Than BP Alone
Since the heart spends more time in diastole than systole, MAP accounts for approximately 2/3 of the cardiac cycle, providing a more accurate assessment of tissue perfusion.
Sepsis Management Target
The Surviving Sepsis Campaign guidelines recommend maintaining MAP ≥65 mmHg in septic patients to ensure adequate organ perfusion.
Critical Care Standard
MAP is essential for managing blood pressure in shock, sepsis, and post-operative care. Values below 60 mmHg may indicate inadequate tissue perfusion requiring intervention.
Clinical Guideline
Sepsis Target: MAP ≥65 mmHg

How MAP Calculation Works
Our calculator uses the standard medical formula to instantly compute Mean Arterial Pressure from your blood pressure readings.
Enter Blood Pressure
Input your systolic (SBP) and diastolic (DBP) blood pressure readings in mmHg. These values are typically obtained from a blood pressure cuff or monitor.
Apply Formula
The calculator automatically applies the standard MAP formula: MAP = (SBP + 2×DBP) ÷ 3. This formula weights diastolic pressure twice as much as systolic.
Get Results
Instantly receive your MAP value with clinical interpretation. Results include status indicators showing whether your MAP is normal, low, or requires attention.
Standard MAP Formula
MAP = (SBP + 2 × DBP) ÷ 3Diastolic pressure is weighted twice as much because the heart spends approximately 2/3 of the cardiac cycle in diastole.
