Flashcards in Chapter 4 Deck (11):
1

Nasopharynx

Moist mucous membranes, highly vascular, easily damaged. Use lots of lube and slide ETT bevel side to septum

2

Hypopharynx

Epiglottis is attached to hyoid and therefore to the mandible. Tongue can produce some occlusion but its epiglottis that creates full occlusion of airway

3

Pyriform fossa

On either side of epiglottis, tubes can end up in here. Tube will tent skin on superior aspect of laryngeal prominence

4

Larynx

Vocal cords surrounded by C shaped cartilage with open part of C facing posteriorly. Cords can close entirely in some people with laryngospasm. ELM can help bring cords into view (BURP) back up right pressure (back towards esophagus, then up and slightly right

5

Sellick maneuver

Pressure on the cricoid cartilage will close off esophagus to 100cm H2O. Esophagus is directly posterior to cricoid cartilage

6

Cric

Palpate thyroid for most prominent portion, go inferior for second bump (cricothyroid membrane)

7

15, 20, 25

15cm from teeth to vocal cords, 20cm to sternal notch, 25cm is the carina.
3X diameter for ETT at teeth (size 8 should be no more than 24cm)

8

Extension/flexion

Can move tube 2.5cm

9

Airway and reflexes

Suction, NPA, OPAs can stimulate protective reflexes and trigger vomiting, cardiovascular stimulation, and increase ICP

10

Poor mans NPA

6mm ET tube cut

11

NPA bleeding

Minor bleeding leave it in
