Airway Part 2- Bag Valve Mask Adjuncts

How do you oxygenate a patient (while you are preparing for RSI) if suction, moving the tongue, and basic BVM ventilation are unsuccessful?



Pharyngeal Airways



* These tools bypass the posterior portion of the tongue to help with BVM ventilation* Nasopharyngeal Airway (NP)* Measure from earlobe to tip of nose* TEST QUESTION: Don’t use in a patient with possible skull fracture* Oropharyngeal Airway (OP)* Measure from earlobe to corner of mouth



Laryngeal Mask Airway (LMA)



* Essentially a modified BVM to place inside the mouth* It fits OVER the larynx (cords, epiglottis, etc)



Retroglottic Airways



* “King”* “Combitube”
