Right heart catheterization(RHC) is a technique of inserting a catheter into the right heart and pulmonary artery via a peripheral vein, to evaluate hemodynamics and oxygen dynamics. When Swan-Ganz catheter is used, it is called pulmonary artery catheterization (PAC). PAC plays an important role in the diagnosis and evaluation of pulmonary hypertension (PH), and hemodynamic assessment of critically ill patients. We developed this consensus to improve the overall quality of RHC operation, especially the PAC standardization in the diagnosis and evaluation of PH, thereby to promote the diagnosis and treatment of PH in China.
右心导管检查（right heart catheterization，RHC）是将导管经外周静脉送入右心及肺动脉，并进行血流动力学及氧动力学检测的技术。其中使用Swan-Ganz导管进行检查的技术称之为右心漂浮导管技术。右心漂浮导管检查在肺动脉高压诊断与评估中有着不可替代的作用，在重症患者的血流动力学评价中具有重要的临床指导价值。为进一步提高我国右心导管操作水平、尤其在肺动脉高压患者诊断、评估中的规范性，特制定本操作流程，以进一步推动我国肺动脉高压诊疗工作。.
