PRIMA Guedel oral airway, sterile

The Guedel Airway can be used on any unconscious patient. The pipe, of appropriate size and correctly inserted, will press the base of the tongue, preventing it from falling backward, toward the posterior larynx. It has a semicircular design, is made of semi-rigid polyethylene, and is disposable. The product is sterile, being individually packaged.
The role of the pipe is to lift the tongue off the posterior pharyngeal wall to prevent airway obstruction.
Instruction: Insert the airway upside down, with the curvature toward the tongue to prevent pushing the tongue back into the pharynx. When the airway reaches the back of the tongue, rotate the device 180 degrees. The tip should point down as it approaches the posterior wall of the pharynx, and the curvature should follow the contour of the roof of the mouth. Do not use it during convulsions!
