Mechanical/Structural issues predispose to aspiration pneumonia. Which is included?

• A. Nasogastric (NG) tubes
• B. Tracheostomy
• C. Endotracheal intubation
• D. Mechanical ventilation

Answer: (B)

A device or condition that alters the airway in a way that bypasses the body’s normal protective defenses greatly increases the risk of aspirating oropharyngeal or gastric contents. A tracheostomy creates a direct opening into the trachea, bypassing the larynx and epiglottis, which are key barriers to aspiration. Because the normal cough reflex and mucociliary clearance are less effective around a tracheostomy tube, secretions can accumulate and be aspirated into the lower airways, making pneumonia more likely in these patients. Other options don’t change the airway’s protective structure in the same way. A feeding tube into the stomach can permit reflux and aspiration, but it doesn’t create a direct airway barrier. Endotracheal intubation and mechanical ventilation are important support measures and can contribute to pneumonia risk, but they are temporary management factors rather than a lasting mechanical alteration of airway defense.
