Instructions for use

The proper size is selected by holding the airway against the side of the patient's face and ensuring that it extends from the corner of the mouth to the angle of the jaw. If the airway is improperly sized, it will occlude the airway.

An oral airway is placed by inserting a tongue depressor into the patient's mouth to displace the tongue downward and then passing the airway into the patient's mouth, slipping it over the patient's tongue.

In adults it is inserted into the mouth upside-down, and rotated into the normal position once it is inserted about half way.

Lubricant may be useful if the mouth is excessively dry.

MSF requirements

Replaces the reusable cannulas as these become rare in the market.

The sterility of the device is not a requirement, but is an option that may be choosen because of availability. In this case the specific NST codes should be used to allow a proper stock management.
