Various laboratory tests (CBC, troponin, BNP, etc.) and imaging studies (chest x-ray, CT scan, ultrasound) are often used to diagnose and classify the cause of pulmonary edema.[4][5][6] Treatment is focused on three aspects: improving respiratory function, treating the underlying cause, and preventing further damage and allow full recovery to the lung. Pulmonary edema can cause permanent organ damage, and when sudden (acute), can lead to respiratory failure or cardiac arrest due to hypoxia.[7] The term edema is from the Greekοἴδημα (oidēma, "swelling"), from οἰδέω (oidéō, "(I) swell").[8][9]
