Flashcards in Airway Management Deck (17):
1

Airway

the passageway by which air enters or leaves the body. the structures of the airway are the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs

2

Patent Airway

an airway (passage from nose or mouth to lungs) that is open and clear and will remain open and clear, without interference to the passage of air into and out of the body.

3

Bronchoconstriction

the contraction of smooth muscle that lines the bronchial passages that results in a decreased internal diameter of the airway and increased resistance to air flow.

4

Stridor

a high pitched sound generated from partially obstructed air flow in the upper airway

5

Ventilation

breathing in and out (inhalation and exhalation), or artifical provision of breaths

6

Alveolar Ventilation

the amount of air that reaches the alveoli

7

Pulmonary Respiration

the exchange of oxygen and carbon dioxide between the alveoli and circulating blood in teh pulmonary capillaries

8

Cellular Respiration

the exchange of oxygen and carbon dioxide between cells and circulating blood

9

Respiration

the diffusion of oxygen and carbon dioxide between the alveoli and the blood (pulmonary respiration) and between the blood and the cells (cellular respiration). Also used to mean, simply breathing

10

Hypoxia

an insufficiency of oxygen in the body's tissues

11

Respiratory Distress

increased work of breathing; a sensation of shortness of breath

12

Respiratory Failure

the reduction of breathing to the point where oxygen intake is not sufficient to support life.

13

Respiratory Arrest

when breathing completely stops

14

Cyanosis

a blue or gray color resulting from lack of oxygen in the body

15

Cricoid Pressure

pressure applies to the cricoid ring to minimize air entry into the esophagus during positive pressure ventilation also called Sellick Maneuver

16

Stoma

a permanent surgical opening in the neck through which the patient breaths

17

Oxygen Cylinder

a cylinder filled with oxygen under pressure
D cylinder contains about 350 L
E cylinder contains about 625 L
M cylinder contains about 3,000 L
G cylinder contains about 5,300 L
H cylinder contains about 6,900 L
