Mean arterial pressure (MAP) target range?

Mean arterial pressure (MAP) target range?

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

Answer: (D)

Mean arterial pressure is the average pressure driving blood through the arteries and sustaining perfusion to vital organs like the brain and kidneys. It’s commonly estimated with MAP ≈ (SBP + 2×DBP) / 3, which reflects the balance of systolic and diastolic pressures over the cardiac cycle. In adults, a normal MAP normally falls around 70 to 105 mmHg. This range provides enough perfusion pressure to maintain organ function without imposing excessive afterload that could strain the heart or vessels. Values below about 60–70 mmHg raise concern for inadequate cerebral and renal perfusion, while sustained values above roughly 105 mmHg can indicate hypertension and increased risk of vascular injury. Among the given ranges, 70–105 mmHg best represents the typical target for maintaining adequate organ perfusion in a stable adult. In shock or critical illness, you might use a lower threshold (e.g., MAP ≥65 mmHg) as a minimum goal, but the standard non-acute target remains around 70–105.
