Mean Arterial Pressure (MAP) Calculator
Calculate Mean Arterial Pressure from systolic and diastolic BP. The key perfusion metric in sepsis, shock, neurocritical care, and anaesthesia — guides vasopressor titration.

Formula: MAP = (SBP + 2 × DBP) / 3 ≈ DBP + ⅓ × (SBP − DBP)
Enter valid SBP and DBP (DBP must be less than SBP) to calculate MAP.
★ DoctorScribe — Complete Clinic Management
MAP trends across every BP reading
DoctorScribe computes MAP and pulse pressure from each vital entry and graphs trends over time — instant flagging when MAP drifts below your patient-specific target.
Clinical Disclaimer: MAP estimation via the (SBP + 2×DBP)/3 formula is accurate for HR 60–100. In tachycardia or bradycardia, arterial line direct MAP is more reliable. Target MAP varies by clinical context (sepsis ≥ 65, neurocritical ≥ 80–90, traumatic SCI ≥ 85). Always verify against your local prescribing reference and apply clinical judgment.
Hemodynamics, automatically tracked
DoctorScribe auto-calculates MAP from every BP entry, flags MAP < 65 in tagged sepsis patients, and trends pulse pressure / shock index — all inside the chart.
