Endotracheal Tube Here is a picture of an

endotracheal tube. The parts of an endotracheal

tube will be discussed later. You will have the opportunity

to see and use an endotracheal tube during your lab session. This opportunity will provide you with the hands-on experience in understanding the purpose of an endotracheal tube.

Purpose:– Risk of aspiration

» Example: Dysphagia-which is difficulty swallowing

– Relief of upper airway obstruction due to swelling

» Examples: Laryngospasm-which is swelling of the vocal cords Epiglottitis-which is swelling of the epiglottis Glottic edema-which is swelling of the larynx

Endotracheal Tube

Prevent airway obstruction of the “at risk” airway– Reflexes obtunded by paralysis– Drugs– Loss of consciousness– Neuromuscular disease

It is the relaxation of an anatomical structure within the airway that causes the airway obstruction. The most common cause is the relaxation of the tongue which blocks the airway.
