What is the typical size range for an adult oropharyngeal airway?

An adult oropharyngeal airway is typically sized within the range of 80-100 mm. This sizing is crucial because the airway must fit appropriately to maintain proper ventilation and prevent airway obstruction. An oropharyngeal airway that is too small may not adequately hold the tongue forward, which can lead to airway issues, while one that is too large can cause trauma to the oropharynx and may even stimulate the gag reflex, making it difficult to maintain airway patency.

When selecting an oropharyngeal airway, it's important to consider the patient's anatomy to ensure the device effectively keeps the airway open. The size range of 80-100 mm is designed to accommodate the typical dimensions of an adult oropharynx while ensuring maximum efficacy and safety during emergency situations.
