Which position should be avoided in patients at risk for aspiration?

The supine position should be avoided in patients at risk for aspiration because it allows for the possibility of oral contents, including food, liquid, or secretions, to flow back into the throat and potentially into the lungs. In this position, gravity does not assist in keeping the contents of the stomach and mouth in place, which increases the risk of choking and aspiration pneumonia.

When patients are sitting upright or in Fowler's position, the angle of the body helps prevent the backward flow of materials from the mouth or stomach into the trachea. The prone position is generally also not a concern for aspiration, as it allows for any secretions to drain out of the mouth rather than being inhaled. Therefore, positioning a patient upright or in Fowler's position is critical for those at risk to ensure their safety and minimize aspiration risks.
