What is the purpose of a properly placed oropharyngeal airway?

A properly placed oropharyngeal airway is specifically designed to keep the tongue from obstructing the airway, especially in unconscious patients. When an individual is unresponsive, the relaxed muscles, including the tongue, can fall back and block the airway, leading to inadequate airflow and potential respiratory distress. The oropharyngeal airway achieves this by providing a rigid structure that holds the tongue forward, ensuring that the airway remains clear and open for air to pass through the pharynx.

This function is crucial for maintaining an open airway and ensuring that oxygen can reach the lungs effectively. It's important to understand that while the airway can assist with ventilation and help facilitate suctioning in specific scenarios, its primary and most critical role is to prevent the tongue from obstructing the airway.
