Pulmonary artery systolic pressure – MCQ – Answer

Pulmonary artery systolic pressure – MCQ – Answer Normal pulmonary artery systolic pressure – Correct Answer: b) 15 – 30 mm Hg Pulmonary circulation is a low pressure circulation and the pressures are much lower than that of systemic circulation. An acute rise in systolic pressure to 50 mmHg can cause right heart failure in conditions like pulmonary embolism. But gradually rising pressures are better tolerated as the right ventricle has time to compensate by hypertrophy. In severe primary pulmonary hypertension and atrial septal defect with severe pulmonary hypertension, pulmonary pressures can even be suprasystemic. Back to question
