In what situation would you use an oropharyngeal airway (OPA)?

An oropharyngeal airway (OPA) is specifically designed for use in patients who are unresponsive and do not have a gag reflex. This is important because the OPA functions to maintain an open airway by preventing the tongue from obstructing it. In cases where a patient is unresponsive, their ability to protect their airway diminishes significantly, increasing the risk of airway blockage.

Using an OPA in a patient who is alert and oriented, conscious, or able to speak would be inappropriate. These patients typically have the ability to maintain their own airway and will often gag if an OPA is placed, which could lead to further complications. The primary function of an OPA is to help those who cannot manage their airway independently, hence its use is reserved for specific scenarios where airway management is critical, such as in the case of unresponsiveness without a gag reflex.
