What complication can arise from overinflating an endotracheal tube cuff?

Overinflating an endotracheal tube cuff can lead to tracheal necrosis. The cuff is designed to create a seal within the trachea to ensure adequate ventilation and protect the airway from aspiration. However, excessive inflation of the cuff exerts increased pressure on the tracheal wall. This pressure can compromise blood flow to the tracheal tissue, leading to ischemia, and subsequently, necrosis.

Tracheal necrosis can present serious complications, including airway obstruction and potential need for surgical intervention to repair the damage. It’s crucial for healthcare providers to monitor cuff pressure regularly and ensure it remains within safe limits to prevent such complications, maintaining a balance between effective ventilation and tracheal integrity.
