10. Basic Airway Maneuvers ALWAYS REMEMBER THE BASICS These skills should be used prior to initiating any advanced airway technique ◦Head-tilt/chin lift ◦Jaw thrust ◦Modified jaw thrust (for trauma patients) ◦Sellick’s maneuver

11. Airway Management Techniques Patency Maneuvers Head tilt with chin lift, or jaw-thrust maneuver

16. 1.Oropharyngeal Airway Size is measured from the corner of the mouth to the angle of the jaw Sizes range from 0-6 It holds the tongue away from the posterior pharynx, but does not isolate the trachea

17. Simple airway adjuncts R 17

18. Oral Airway continued The oral airway is inserted with the curve towards the side of the mouth Then rotated so that the curve of the airway matches the curve of the tongue

21. 2.Nasopharyngeal Airway Soft plastic or rubber tube that is designed to pass just inferior to the base of the tongue Passed through one of the nares and can be used in patients with an intact gag reflex CONTRAINDICATED in cases of suspected or possible basilar skull fracture Sizes range from 17-26 cm in length and 6-9 mm internal diameter Measured from tip of the nose to the corner of the patients ear

22. Nasal Airway continued The nasal airway is lubricated with a water soluble lubricant The beveled tip is inserted directed towards the septum, with the airway directed perpendicular to the face If resistance is met, rotating the airway may help or the other nare may be used

25. Bag-Valve-Mask Ventilation  Very important skill to know  May provide temporary or definitive airway management.  One person - importance of a good seal.  Two person technique more effective.  In EMS setting may be as useful as endotracheal intubation.
