Ch 15 Airway Management

Question 1

Name the anatomical structures of the upper airway that are above the glottis.

Answer 1

tongue, uvula, pharynx, (nasopharynx, oropharynx, laryngopharynx), epiglottis

Question 2

Name the anatomical structures of the lower airway that are below the glottis.

Answer 2

larynx, vocal cords, trachea

Question 3

The physical act of moving air in to and out of the lungs

Answer 3

ventilation

Question 4

The process of loading oxygen molecules onto hemoglobin molecules in the bloodstream

Answer 4

oxygenation

Question 5

The exchange of oxygen and carbon dioxide in the alveoli and the tissues of the body

Answer 5

respiration

Question 6

The process of exchanging oxygen and carbon dioxide between the alveoli and the blood in the pulmonary capillaries

Answer 6

external respiration (pulmonary respiration)

Question 7

The exchange of oxygen and carbon dioxide between the systemic circulation and the cells of the body

Answer 7

internal respiration (cellular respiration)

Question 8

The amount of air that is moved into or out of the lungs during a single breath

Answer 8

tidal volume

Question 9

respiratory rate X tidal volume =

Answer 9

minute volume

Question 10

Pulling of air into the lungs with negative intrathoracic pressure

Answer 10

negative pressure ventilation

normal breathing

Question 11

Forcing of air into the lungs

Answer 11

positive pressure ventilation

created with a bag-mask device, pocket face mask or mechanical ventilation device

Question 12

The amount of air that moves in and out of the lungs per minute minus the dead space

Answer 12

minute volume

Question 13

A low level of oxygen in arterial blood

Answer 13

hypoxemia

can often be reversed by administering supplemental oxygen

Question 14

A deficiency of oxygen at the tissue and cellular levels

Answer 14

hypoxia

requires more aggressive oxygenation and in some cases, ventilatory support

Question 15

Partial pressure of carbon dioxide

Answer 15

PaCO2
