Mean arterial pressure (MAP) calculation formula explained for nursing students and nurses.
What is a mean arterial pressure (MAP)?
Mean arterial pressure is the pressure in your arteries during one cardiac cycle, and it tells us how well the vital organs (like the renal system, brain etc.) are being perfused. In addition with the brain, the MAP is very important when calculating the cerebral perfusion pressure.
The MAP should be greater than 65 mmHg.
Normal 70-100 mmHg

Mean Arterial Pressure (MAP) is a critical indicator of a patient’s blood pressure and is commonly used in nursing practice to monitor and manage blood pressure. MAP is the average pressure in a patient’s arteries during one cardiac cycle and is calculated by taking the diastolic blood pressure plus one-third of the difference between systolic and diastolic blood pressure.
The formula for calculating MAP is:
MAP = (SBP + 2DBP) / 3
Where SBP is the systolic blood pressure and DBP is the diastolic blood pressure.
The MAP calculation formula is an essential tool in nursing practice as it helps to determine the overall perfusion pressure of a patient’s organs and tissues. The MAP is an important indicator for the amount of oxygen and nutrients being delivered to the body’s organs and tissues.
Nurses use MAP to monitor patients who are critically ill, have suffered from trauma, or are undergoing surgery. They can use the MAP to detect changes in a patient’s blood pressure and adjust medications, fluids, and other interventions to maintain an optimal MAP.
In conclusion, understanding the MAP calculation formula is critical for nurses in managing patients’ blood pressure and ensuring that they receive the best care possible. The MAP helps to identify patients who may be at risk for organ failure, shock, or other complications, and allows nurses to take appropriate action to prevent these adverse outcomes.
