Mean Arterial Pressure Calculator

Leave one field blank to calculate it.
Pulse pressure is always systolic minus diastolic.
Typical normal: 70–100 mm Hg. MAP < 60 mm Hg is usually inadequate for organ perfusion.

What Is Mean Arterial Pressure (MAP)?

The MAP calculator works by estimating the mean arterial pressure using your systolic and diastolic blood pressure values. It also shows pulse pressure and lets you find missing values if just one’s left blank. It’s mostly used in medicine, especially critical care, cardio, ICU monitoring, and sometimes sports science too.

The formula behind it’s simple. MAP is basically how well your blood’s flowin’ to your organs, it gives a better idea than just systolic or diastolic alone. Doctors use it to check if your organs get enough oxygen or not. Normal MAP’s like between 70 and 100 mm Hg. If it goes under 60, might be dangerous, 'cause organs may not get enough blood.

Formula Used

This tool uses:

MAP ≈ Diastolic + (Systolic − Diastolic)/3

Pulse Pressure = Systolic − Diastolic

If any one of the values — MAP, systolic or diastolic — is missing, it’ll reverse-calculate that based on the others. But only one should be left empty, not more or none. Otherwise, won’t work.

How to Use This Calculator

  • Type in your systolic pressure (like 120 mm Hg)
  • Type your diastolic pressure (like 80 mm Hg)
  • Or type MAP if you have it and wanna find one of the others
  • Leave one box blank — only one — to calculate that one
  • Press Calculate to get result instantly
  • Use Clear to reset form

The result includes calculated MAP or pressure, and it shows pulse pressure separately. You can use decimal numbers too, no prob. Tool’s built for flexibility.

Why It’s Useful

  • Calculates MAP from other pressure values
  • Reverse-calculates systolic or diastolic if MAP is known
  • Displays pulse pressure automatically
  • Shows formulas clearly under result
  • Helpful in ICU or clinical cases where BP matters a lot

Remember, values shown here are for general use. If you’re usin’ this for a real health condition, always talk to your doctor or cardiologist. This tool just helps with basic medical math, it's not meant to diagnose anything serious.
