MICROANATOMY

Detailed explanation-1: -Pulmonary edema is an abnormal buildup of fluid in the lungs. This buildup of fluid leads to shortness of breath.

Detailed explanation-2: -Pulmonary edema is a condition in which too much fluid accumulates in the lungs, interfering with a person’s ability to breathe normally. The problem is usually related to heart disease, but it has other possible causes, including kidney failure, blood transfusion reactions, or travel to destinations at high elevation.

Detailed explanation-3: -Pulmonary edema, also known as pulmonary congestion, is excessive liquid accumulation in the tissue and air spaces (usually alveoli) of the lungs. It leads to impaired gas exchange and may cause hypoxemia and respiratory failure.

Detailed explanation-4: -Laryngeal or upper airway mucosal oedema is a common cause of airway obstruction after extubation and is thought to arise from direct mechanical trauma to the larynx by the endotracheal tube (ETT) or due to prolonged surgery.[1, 2] Upper airway oedema predisposes the patient to post-operative airway obstruction.
