Respiratory emergencies Treatment of respiratory emergencies in reptiles follows the same principles known from small animal emergency medicine [12]. In emergency situations, supplemental administration of oxygen via face mask is of short-term benefit. Establishment of a patent airway by endotracheal intubation or placement of a tracheostomy tube has priority if obstructive processes are present. The presence of large amounts of fluid and secretions within the tracheal lumen requires removal by suction. Once the reptile is stabilized, obstructive processes such as abscesses or foreign bodies within the oral cavity or tracheal lumen should be removed.
