Hi Matt, can i check why did u divide it by 3? Understand that it takes more time to fill the heart, but is dividing the difference of the pressures by 3 an arbitrary number that you came up with or is it a specific formula (havent see it anywhere in the text). Thanks!
it's divided by 3 because 2/3 of cardiac cycle is in diastolic phase (filling ventricles) & 1/3 in systolic (pumping ventricles). I use an easier method, ((diastolic X 2) + systolic) ÷ 3 = MAP.. I find it faster and easier to remember.

That's the formula. You can google MAP equation and see it.

Wow
Very helpful and easy to understand video on how to simply calculate the mean arterial pressure- thank-you!
.... but what's the nice arterial pressure??
Depends on the person but the example 120/80 MAP 93 is pretty standard
What we do with Mean Arterial
It can be used clinically to determine perfusion of blood to body tissue.
Why isn’t MAP= ( systolic BP + Diastolic BP) /2?
Because more time is spent in diastole (filling)
