What is the primary purpose of a Murphy eye on an endotracheal tube?
- To monitor carbon dioxide levels
- To provide an alternate pathway for gas flow
- To inflate the cuff
- To measure the depth of insertion
Explanation:
The Murphy eye is a small hole on the side of the endotracheal tube, opposite the bevel. Its purpose is to act as a safety feature, providing an alternate route for gas to flow in case the primary opening (the bevel) becomes occluded by the tracheal wall or mucus.
