This fluid may also become infected if the collection is not resolved by the immune process of the body. Caused by excess fluid in the lungs, pulmonary edema is a condition in which fluid collects in the lung’s air sacs and makes it hard to breathe. Can cause bluish discolouration of skin due to improper oxygenation. It is only after a thorough examination that the presence of pulmonary edema is confirmed. The advent of high-resolution CT scanning of the chest has led to its increasing use. The relative amounts of intravascular and extravascular fluid in the lung are … Stage of red hepatisation: now that the congestion resolves to some extent, the lung now becomes hard in consistency and become red in appearance due to the leakage of exudate and even a few blood cells. Therefore, the doctor has to remain prepared to provide assisted ventilation to the patient as soon as he begins to show signs of respiratory fatigue. Website design by.

Pulmonary edema is mostly caused when the fluid in the lungs can’t drain out properly as seen in cases of heart failure. In cases of left heart failure the blood pools back into the lungs and causes massive collection of fluid thus causing breathing difficulty, cough and respiratory distress. Physical exam is positive for increased work of breathing, diffuse crackles most prominent at the bases, and overall decreased breath sounds. Pulmonary Edema.
