Comparing to baseline, the pressures of SVCs and IVCs were lower. Meanwhile, the pressure drops between venae cavae and pulmonary artery turned negative. Section A is the pressures at SVCs and IVCs. Section B is the pressure drops between venae cavae and RPAs. Section C is the mass flow rates at LPAs and RPAs. BSL, baseline; SVC, superior vane cava; IVC, inferior vena cava; LPA, left pulmonary artery; RPA, right pulmonary artery.
