Which MAP range is considered the target?

• A. 70-105
• B. 60-90
• C. 90-120
• D. 50-70

Answer: (A)

Mean arterial pressure (MAP) is the perfusion pressure that tissues receive from the arterial system. It combines systolic and diastolic pressure and is often estimated with MAP ≈ diastolic pressure + one third of the pulse pressure. In most adults, maintaining a MAP roughly in the 70–105 mmHg range provides enough perfusion to vital organs (like the brain and kidneys) without pushing pressures into risky hypertension. For example, a typical BP of 120/80 yields a MAP around 93 mmHg, which fits within this target window. Ranges that are too low (such as starting around 50–70) risk inadequate organ perfusion, while ranges that are too high (like 90–120) can indicate or cause hypertension-related stresses. Therefore, 70–105 mmHg is the best target range for MAP in stable adults.
