aspiration
Entry of food, liquid, or saliva into the airway below the level of the vocal folds during swallowing.
Full Definition
Aspiration occurs when material intended for the digestive tract instead enters the respiratory system below the vocal fold level during swallowing. This serious condition can lead to aspiration pneumonia, respiratory complications, and even death if not properly managed. Speech-language pathologists assess aspiration risk through clinical evaluation and instrumental studies like videofluoroscopic swallow studies or fiberoptic endoscopic evaluation of swallowing. Silent aspiration, where the patient shows no outward signs like coughing, is particularly dangerous. Management strategies include diet modifications, compensatory techniques, and in severe cases, alternative feeding methods.
Usage
Usage note: Distinguish from penetration (material enters laryngeal vestibule but not below vocal folds).
