What indicates correct technique when inserting an oropharyngeal airway?

The correct technique for inserting an oropharyngeal airway involves having the lip pointed towards the roof of the mouth initially, which allows the airway to follow the natural curvature of the oral cavity as it is inserted. After reaching the appropriate depth, the rescuer then rotates the airway 180 degrees so that the curvature fits into the pharynx properly, ensuring that it maintains patency in the airway.

This method is particularly effective because it avoids pushing the tongue backwards, which could obstruct the airway, and positions the device correctly to help maintain an open airway.

Other techniques might not effectively secure the airway; for example, pushing it straight down without rotation could cause improper placement or may not account for the shape of the airway, risking further obstruction. Similarly, placing the airway parallel to the tongue doesn't utilize its design to clear the airway properly and can lead to complications or ineffective insertion.
