Laboratory Findings
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.
