4b-Endotracheal Intubation Flashcards
Introduction of an endotracheal tube provides an open airway to administer
Oxygen, gaseous medicine, or anesthetics
Endo
Within
The windpipe
A membranous tube with cartilaginous rings that conveys inhaled air from the larynx to the bronchi and back
Trachea
Flap of cartilage at the root of the tongue that covers the trachea is when swallowing
Epiglottis
A cartilaginous structure at the top of the trachea which protects trachea and enables phonation (vocalization)
Larynx
Foldings in cartilage in the central area of the larynx
Laryngeal folds
What the laryngeal folds do
Vibrate to create phonation
Open during inspiration
Relax during expiration
Opening between laryngeal folds through which air passes
Glottis
Hole where intubation tube goes down
Glottis
Purposes of endotracheal intubation
Maintain patent (open) airway
Introduce oxygen with or without anesthetic gas
Prevent aspiration of vomit or saliva
Provides mechanical ventilation if necessary
Purpose of the cuff on ET tube
Creates seal preventing escape of gas between tube and trachea, prevents passage of vomitus down trachea outside of the tube
If tube too long it can hit the
Bronchi
You can only intubate when the jaw is what
When the jaw tone is lax enough
When to intubate
When animals are anesthized, not breathing on their own, airway needs to be opened
An “armored” tube is made of the
Spiral metal or rubber coil in a latex tube
