Mean arterial pressure is 100 mmHg and systolic pressure is 150 mmHg. Using the usual resting approximation, find diastolic pressure.
110 mmHg 75 mmHg 70 mmHg 50 mmHg Practise this question in The GATE Grind →
Show answer and explanation Correct answer: (B) 75 mmHg
Explanation Use MAP≈DBP+(SBP−DBP)/3=(SBP+2DBP)/3. Thus 300=150+2DBP, yielding DBP=75 mmHg, B. Mean arterial pressure is a time-weighted pressure average rather than the arithmetic average of systolic and diastolic values.
