Technique•Measure from tip of nose to tragus of ear•Ensure airway will fit through nostril•Lubricate with water-soluble lubricant or anesthetic jelly•Insert with bevel toward base of nostril or septum•If resistance is met, try other nostril•Do not use in patients with mid-face trauma or possible basilar skull fractures

Technique•Measure from corner of mouth to earlobe or angle of jaw•In adults insert with tip facing roof of patient’s mouth, advance until resistance encountered, turn 180o until flange comes to rest on patient’s teeth•In infants and children use tongue depressor to lift tongue, insert oral airway right side up•Too long –press epiglottis•Too short-force tongue back
