Normal pulmonary artery systolic pressure at rest is 18 to 25 mm Hg, with a mean pulmonary pressure ranging from 12 to 16 mm Hg. This low pressure is due to the large cross-sectional area of the pulmonary circulation, which results in low resistance.

chronic pulmonary thromboembolism, seven patients; venous PH, six patients; and control subjects with normal pulmonary artery pressure, nine patients. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: High-fidelity pulmonary artery pressures were obtained when patients were at rest.

The level of thromboxane B2, a stable metabolite of thromboxane A2, in the pulmonary artery was abnormally high (140 pg/ml). This suggested that vasoconstriction of the pulmonary artery and microthrombosis would ... The pulmonary artery pressure was normal eight months after the start of therapy with beraprost sodium.

The systolic pressure (normal, 15 to 30 mm Hg) and diastolic ... Pulmonary artery occlusion pressure (PAOP): With the balloon inflated, pressure at the tip of the catheter reflects the static back pressure of the pulmonary veins. The balloon must not remain inflated for > 30 sec to prevent pulmonary infarction.

When properly positioned in a branch of the pulmonary artery, the distal port measures pulmonary artery pressure (~ 25/10 mmHg) and the proximal port measures right atrial pressure (~ 0-3 mmHg). The balloon is then inflated, which occludes the branch of the pulmonary artery.
