Overview
Laboratory Findings
Laboratory findings | ECG | CXR | Cardiac enzymes | PCWP | QS/QT | Edema fluid/serum protein |
---|---|---|---|---|---|---|
Cardiogenic pulmonary edema | Ischemia/Infarct | Peri-hilar distribution | May be elevated | >18 mmHg | Small elevated | <.5 |
Noncardiogenic pulmonary edema | Usually normal | Peripheral distributions | Usually normal | <18 mmHg | Large elevated | <.7 |
Brain Natriuretic Peptide
B-type natriuretic peptide (BNP) is elevated in the patient with cardiogenic pulmonary edema. A low BNP (<100 pg/ml) makes a cardiac cause very unlikely and is associated with non-cardiogenic pulmonary edema.
Oxygen Saturation
Low oxygen saturation or hypoxia may be present on arterial blood gas readings.
