Mean Arterial Pressure (MAP) Estimate Formula

The following two example problems outline the steps and information needed to calculate the Mean Arterial Pressure (MAP) estimate.

MAP ≈ (2*DBP + SBP) / 3

Variables:

  • MAP is the Mean Arterial Pressure estimate (mmHg)
  • DBP is the diastolic blood pressure (mmHg) 
  • SBP is the systolic blood pressure (mmHg) 

To calculate the MAP estimate, multiply the diastolic blood pressure by 2, add the systolic blood pressure to the value, then divide the result by 3.

How to Calculate Mean Arterial Pressure (MAP)?

The following steps outline how to calculate the Mean Arterial Pressure (MAP) estimate.

  1. First, determine the diastolic blood pressure (mmHg). 
  2. Next, determine the systolic blood pressure (mmHg). 
  3. Next, gather the formula from above = MAP ≈ (2*DBP + SBP) / 3.
  4. Finally, calculate the MAP estimate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

diastolic blood pressure (mmHg) = 80

systolic blood pressure (mmHg) = 120
