What this calculator does

Mean arterial pressure (MAP) approximates average arterial pressure during the cardiac cycle. It is used in perfusion targets during shock resuscitation and ICU care.

Formula and variables

Displayed formula: (SBP + 2×DBP)/3

The engine evaluates: Mean Arterial Pressure (mmHg). Variable names match the input field keys so you can trace each step from entry to output.

How to use this tool

1. Open the Mean Arterial Pressure and enter your values using the units shown beside each field.
2. Review that inputs are within the typical physiological range before you calculate.
3. Read the result together with the interpretation notes below and your local clinical context.

How to interpret the result

Adults often target MAP ≥65 mmHg in septic shock, though goals vary by comorbidity, chronic hypertension, and end-organ perfusion markers. Pair MAP with urine output, lactate, and mental status.

Clinical context

Cardiovascular calculations support assessment but never replace ECG, imaging, troponin trends, or emergent reperfusion pathways when STEMI is suspected.

Limitations and disclaimer

This tool supports education and clinical triage only. It does not replace professional medical advice, diagnosis, or treatment. Reference ranges vary by laboratory, age, pregnancy status, and comorbidity. Always confirm critical decisions with institutional protocols and qualified clinicians.
