PURPOSE: In patients with Pulmonary Arterial Hypertension, (PAH), gas exchange abnormalities manifest as increased dead space [Vd/Vt]) during Cardiopulmonary Exercise Testing (CPExT). How gas exchange parameters during CPExT compare with mean pulmonary artery pressure (mean PAP) and pulmonary vascular resistance (PVR) in PAH has not been evaluated. The objective of this study was to determine if mean PAP and PVR correlate with gas exchange parameters (Vd/Vt and oxygen saturation) during CPExT in PAH.
