Document Summary
Introducing tube (laryngoscope) through the oral cavity into the larynx then into the trachea. Corniculate cartilages when looking down = corniculate tubercles. Through the rima glottis (between the true vocal cords) can see the hyaline cartilage of the trachea. Tube is introduced through the vocal cords and into trachea. Cervical spine needs to be extended for 2 reasons: prevents airway obstruction due to the tongue. Tongue is the most common cause of airway obstruction in reduced consciousness. When the c spine is extended, this opens the space between the palette, oropharynx and laryngopharynx and larynx so you don"t choke: 3 axis alignment theory. 3 axis alignment theory: oral cavity axis, pharyngeal axis, laryngeal axis. The more discrepancy between the 3, the harder it is to perform intubation, you want to align them all as close as possible. Flex lower c spine + extend the upper c spine 3 axis start to approximate themselves more =
