Which position is associated with increased aspiration risk in critically ill patients?

• A. Prolonged supine positioning
• B. Prolonged prone position
• C. Lateral decubitus
• D. Upright

Answer: (A)

Position and gravity directly influence aspiration risk, especially in critically ill patients who may have delayed gastric emptying and reduced airway reflexes. In the supine (lying flat) position, the esophagus and airway align in a way that refluxed or regurgitated gastric contents are more likely to reach the larynx and be aspirated. Elevating the head of the bed or keeping the patient upright uses gravity to keep gastric contents in the stomach and helps airway protection and clearance of secretions. Lateral decubitus and prone positions have their own clinical considerations, but they do not carry the same higher risk of aspiration as lying flat. Therefore, prolonged supine positioning is associated with the greatest aspiration risk in critically ill patients.
