What head-of-bed elevation is recommended to minimize aspiration risk in critically ill patients receiving enteral nutrition?

• A. 0 degrees
• B. 15-30 degrees
• C. 30-45 degrees
• D. 60 degrees

Answer: (C)

Elevating the head of the bed to a semirecumbent position around 30-45 degrees reduces the risk of aspiration during and after enteral feeding by using gravity to limit reflux of gastric contents into the esophagus and airway. This range provides a practical balance between minimizing reflux and avoiding issues that can come with excessive elevation, such as patient discomfort, pressure injuries, or tube dislodgement. A flat position (0 degrees) allows reflux to reach the airway more easily, while a very steep angle (60 degrees) isn’t typically needed to further reduce risk and can introduce other problems. Maintain this elevation during feeding and as feasible after feeding to minimize aspiration risk.
