Which of the following statements describes the relationship between the pulmonary circulation and the pulmonary vascular bed?
a. The pulmonary circulation is a high-pressure system with normal pressures averaging 100/60 to 120/70 mm Hg.
b. Because of the low pulmonary arterial pressures, the right ventricular wall thickness needs to be only one-third that of the left ventricle.
c. Pulmonary hypertension is defined as increased pulmonary artery systolic pressure above 20 mm Hg.
d. The most common cause of pulmonary hypertension is right-sided heart failure.
B
Because of low pulmonary artery pressures, right ventricular wall thickness needs to be only approximately one-third of left ventricular wall thickness. Pulmonary hypertension is defined as increased pressure (pulmonary artery systolic greater than 35 mm Hg and pulmonary artery mean less than 25 mm Hg at rest or less than 30 mm Hg with exertion) within the pulmonary arterial system. Pulmonary hypertension increases the afterload of the right ventricle and, when chronic, can result in right ventricular hypertrophy (cor pulmonale) and failure.
