Overview
Pulmonary artery catheterization is the gold standard test for the diagnosis of pulmonary edema. Elevated pulmonary-artery pressure indicates cardiogenic pulmonary edema or pulmonary edema due to volume overload.
Diagnostic study of choice
Pulmonary-Artery Catheterization
Pulmonary artery catheterization is the gold standard test for the diagnosis of pulmonary edema.[1][2]
- Insertion of a pulmonary arterial catheter (a.k.a. a Swan-Ganz catheter) 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.
- Pulmonary artery catheterization is commonly used in ICU patients with severe acute decompensated CHF.
- Studies showed no improvement in mortality rate or decrease in the number of hospitalization in patients who underwent pulmonary artery catheterization.[3]
