Direct laryngoscopy using a straight blade

A) The head is positioned with the right hand, and the mouth is opened using the fifth finger of the left hand (if necessary). B) Alternatively, the mouth may be opened with the thumb and index finger of the right hand using a "scissor" technique. C) The laryngoscope blade is inserted under direct vision over the tongue and then the tip of the blade is used to directly retract the epiglottis, revealing the vocal cords and glottic opeing.
