This exhibit depicts proper vs. improper intubation of a patient. Intubation is the insertion of a tube into the trachea to preserve airways or administer certain medications. This procedure is usually performed after administering general or local anesthesia, however it can also be performed without anesthetic in emergency situations. During a proper intubation procedure, the endotracheal tube is passed through the mouth, oropharynx, and larynx to enter the trachea. Improper placement of the endotracheal tube into the esophagus blocks the pharynx, disrupting airflow into the trachea. This results in hypoxia and potentially fatal asphyxia.
