Packaging & Labelling
Quantity per box differs according the manufacturer.
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.
Precautions for Use
Do not resterilize
MSF requirements
The sterile cannulas have replaced the non-sterile ones as they are more available on the market.
