Aspiration is the entry of food, liquid, saliva, or other material into the airway below the level of the vocal folds. It can occur before, during, or after the swallow, and may be overt (with coughing) or silent (without obvious signs). If untreated, aspiration can lead to respiratory complications such as aspiration pneumonia. SLPs play a central role in assessing and managing aspiration to ensure safe and effective swallowing.
