Patent airway

**Patent Airway**

A patent airway refers to an open and unobstructed passage that allows air to flow freely to and from the lungs. Ensuring a patent airway is a critical concept in medical and emergency settings, as any blockage can lead to respiratory distress or failure. This term is commonly used in respiratory therapy, anesthesia, emergency medicine, and critical care to describe the state of the respiratory tract being clear and functional for effective breathing.
