How should an oropharyngeal airway (OPA) be inserted?

The correct method for inserting an oropharyngeal airway (OPA) is upside-down and requiring rotation to a position where it fits properly into the oropharynx. The insertion should begin with the OPA pointed towards the roof of the mouth. As it reaches the back of the throat, it is then rotated 180 degrees to ensure that the curve of the airway aligns with the anatomy of the oropharynx. This technique helps prevent injury to the soft tissues and assists in maintaining a clear airway by properly positioning the device.

In contrast, simply inserting the OPA following the contour of the tongue or directly into the mouth without any rotation may lead to it pressing against the tongue instead of displacing it, which would not secure an open airway effectively. The use of a suction device prior to inserting the OPA is not standard practice in this scenario, as the OPA is designed to maintain an open airway rather than clear secretions.
