Hemodynamic values on pulmonary artery catheter associated with the causes of an elevated right atrial pressure

RVp: RV pressure; PAp: pulmonary artery pressure; CI: cardiac index; SVR: systemic vascular resistance; PAOP: pulmonary artery occlusion pressure; RV: right ventricle; ↑: increased; ↔: normal; ↓: decreased; LV: left ventricle.
* In the setting of RV pathology, the elevation in PAp is mild. In contrast, the elevation in PAp is much greater in those with pulmonary arterial hypertension.
