An endotracheal tube with Murphy eye, also known as an ET tube with Murphy aperture, is a device that is used to help you breathe during surgical procedures or while on life support. This tube is inserted through the mouth or nose and into the trachea to assist airway management. Synonyms for this device include: intubation tube, breathing tube, ventilation tube, airway tube, tracheal tube, and endotracheal catheter. The Murphy eye is a small hole in the side of the tube, which provides an alternative route for air to pass through in case the main opening becomes blocked. This innovative design improves patient safety and ensures uninterrupted airflow during medical procedures.
