Pulmonary edema cardiac catheterization

Cardiac Catheterization
Insertion of a pulmonary arterial catheter (a.k.a. a Swan-Ganz catheter) may be required to distinguish between the two main forms of pulmonary edema and to help guide management. In patients with cardiogenic pulmonary edema the pulmonary artery pressure will be elevated. Among patients with non-cardiogenic pulmonary edema the wedge pressure will not be elevated.
