Central Venous Blood Oxygen Saturation Monitoring in Patients With Chronic Pulmonary Arterial Hypertension Treated With Continuous IV Epoprostenol

SVC oxygen saturation and BNP level predict hemodynamics associated with lower survival rates and may be useful as “noninvasive” markers of prognosis in epoprostenol-treated PAH patients. BNP levels have a lower sensitivity relative to specificity, and a normal BNP level did not exclude a high RAP or low PA oxygen saturation.
