What can cause airway obstruction?

Airway obstruction occurs when there is a blockage in the airway that prevents proper airflow. The tongue can cause airway obstruction, especially in unconscious or semi-conscious individuals. When a person loses muscle tone due to loss of consciousness, the tongue can fall back into the throat and block the airway, leading to difficulty in breathing. This is particularly critical in emergency situations, where immediate recognition and intervention are essential for maintaining airway patency and ensuring adequate oxygenation.

Other factors such as excessive exercise or low blood sugar typically do not directly lead to airway obstruction. While overhydration can lead to other complications in respiratory function, it usually does not cause a physical obstruction of the airway itself. Understanding the role of the tongue in airway management is key in nursing practice, especially in emergency and critical care settings.
