Mean Arterial Pressure Calculator

The Mean Arterial Pressure Calculator estimates your average blood pressure during a heartbeat using systolic and diastolic numbers. This tool helps doctors and patients check blood flow to vital organs easily. Whether you are monitoring heart health or checking for low blood pressure, this tool provides clear results. It offers standard and precise calculation methods for better accuracy.

Enter systolic pressure in mmHg (top number)
Enter diastolic pressure in mmHg (bottom number)
Enter heart rate in beats per minute (optional, for more precise calculation)

How Mean Arterial Pressure Is Calculated

Mean Arterial Pressure represents the average pressure in your arteries during one heartbeat. It counts diastolic pressure more than systolic pressure because the heart rests longer than it pumps. We use two common formulas to find this value based on your inputs.

Standard: MAP = (2 × Diastolic + Systolic) ÷ 3
Precise: MAP = Diastolic + (0.01 × HR × (Systolic - Diastolic))

Where:

  • Systolic = Top blood pressure number
  • Diastolic = Bottom blood pressure number
  • HR = Heart Rate
  1. Find your systolic (top) and diastolic (bottom) blood pressure numbers from a recent reading.
  2. Use the standard formula which doubles the diastolic number and adds the systolic number before dividing by three.
  3. If you need exact results, use the precise formula that also includes your heart rate.
  4. This helps account for exactly how long your heart pumps versus rests.

What Your Mean Arterial Pressure Means

Your MAP number tells you if your blood is pushing hard enough to reach your brain and kidneys.

Understanding Your Results

Normal Range (70-100 mmHg): A score between 70 and 100 mmHg usually means your organs are getting enough blood. This is the healthy target for most adults.

Low MAP (<60 mmHg): If your number is below 60 mmHg, your organs might not be getting enough oxygen. This is serious and needs a doctor's help right away.

High MAP (>100 mmHg): A score over 100 mmHg means your heart is working too hard. This can damage your blood vessels over time.

Monitor your MAP regularly if you have blood pressure issues to notice sudden changes early.
