InsertionThe correct size airway is chosen by measuring the device on the patient: the device should reach from the patient's nostril to the earlobe or the angle of the jaw. The outside of the tube is lubricated with a water-based lubricant so that it enters the nose more easily. The device is inserted until the flared end rests against the nostril. Some tubes contain a safety pin to prevent inserting the tube too deeply. Care must be taken to ensure the pin does not stick into the nostril.
