Mean arterial pressure (MAP) normal range is:

Mean arterial pressure (MAP) normal range is:

• A. 60-90 mmHg
• B. 85-100 mmHg
• C. 100-120 mmHg
• D. 120-140 mmHg

Answer: (B)

Mean arterial pressure represents the average pressure that drives blood through the systemic circulation and thus sustains organ perfusion over the cardiac cycle. It can be estimated with MAP ≈ (SBP + 2×DBP) / 3. For most adults, adequate tissue perfusion occurs in the mid-normal range, around 70–100 mmHg, and many clinical references use about 85–100 mmHg as a typical normal working range. This zone keeps essential organs like the brain, heart, and kidneys well perfused without exposing vessels to the higher pressures of hypertension. Values well below this range risk insufficient perfusion and organ injury, while markedly higher values reflect hypertension and associated risks. Therefore, the range around the mid-80s up to 100 mmHg best matches the normal perfusion target.
