Aspiration prevention in dysphagia rests on three pillars: upright positioning at 90 degrees, chin-tuck swallow maneuver, and thickened liquids when the SLP recommends them. Sitting upright with the chin tucked narrows the airway entrance, widens the vallecular space, and redirects the bolus toward the esophagus rather than the trachea. Supine feeding, thin liquids, and unobserved feeding all increase aspiration risk.
