Video - Pulmonary edema

Pulmonary edema is a condition in which fluid accumulates in the lungs, making it difficult for oxygen to pass through the alveoli and into the bloodstream. It is often due to the left ventricular heart failure to adequately remove blood from the pulmonary circulation, which is known as cardiogenic pulmonary edema. It can also be due to an injury to the lung parenchyma or vasculature of the lung - known as noncardiogenic pulmonary edema.

If not treated, pulmonary edema can lead to respiratory failure or cardiac arrest due to hypoxia. Treatment focuses on improving respiratory function, treating the underlying cause, and preventing and avoiding further damage to the lung.
