Use of an Oropharyngeal Airway
Measurement
Insertion
Open victim's airway using head tilt/chin lift.  Insert oropharyngeal airway with the curved end along the roof of the mouth.
As the device approaches the back of the throat (approximately one third to one half in), rotate it a half turn.
The device should drop in without any resistance.  The flange end should rest on the victims lower lip.
