At what angle should a patient be positioned during feeding to prevent aspiration?

The recommended positioning of a patient during feeding is at a 45-degree angle or sitting upright to effectively prevent aspiration. This position helps ensure that the airway remains open and allows for safe swallowing. When a patient sits at this angle, gravity assists in directing the food down the esophagus and helps avoid it entering the airway, which could lead to choking or aspiration pneumonia.

While a 90-degree angle might seem like a safe position, it can sometimes cause discomfort and may not be feasible for all patients, especially those who are elderly or frail. A 30-degree angle may not provide adequate protection against aspiration, and lying flat can significantly increase the risk of aspiration since it allows food and liquids to pool in the throat.

Therefore, a 45-degree angle or sitting upright is the optimal position for feeding, promoting a safe swallowing process while minimizing risks associated with aspiration.
