The nurse cautions the patient to avoid taking anything by mouth after the bronchoscopy until approved by the nurse because the nurse determines when the gag reflex returns.The healthcare provider sprays a local anesthetic agent to depress the gag reflex before passing the bronchoscope.Ingesting oral food or fluid potentially causes choking or aspiration with a depressed gag reflex.The patient is NPO for 8 hours before the bronchoscopy to help prevent aspiration of gastric contents.Intravenous sedation is often used to relax the patient,allowing for easy passage of the bronchoscope.The bronchoscope passes through the oropharynx into the trachea,not through the nose.
