Airway

Question 0

Occasional, gasping breaths that occur after the heart has stopped

Answer 0

Agonal Gasps

Question 1

Metabolism that can proceed only in the presence of oxygen

Answer 1

Aerobic metabolism

Question 2

Upper airway tract or passage above the larynx, which includes the nose, mouth, and throat

Answer 2

Airway

Question 3

The volume of air that reaches the alveoli. It is determined by subtracting the amount of dead space air from the tidal volume

Answer 3

Alveolar Ventilation

Question 4

The metabolism that take place in the absence of oxygen; principle product is lactic acid

Answer 4

Anaerobic Metabolism

Question 5

Absence of spontaneous breathing

Answer 5

Apnea

Question 6

A body part or condition that appears on both sides of the midline

Answer 6

Bilateral

Question 7

Subdivision of the smaller bronchi in the lungs; made of smoothe muscle and dilate or constrict in response to various stimuli

Answer 7

Bronchioles

Question 8

The ability of the alveoli to expand when air is drawn in during inhalation

Answer 8

Compliance

Question 9

A method of ventilation used primarily in the treatment of critically ill patients with respiratory distress; can prevent the need for endotracheal intubation

Answer 9

Continuous Positive Airway Pressure (CPAP)

Question 10

The portion of the tidal volume that does not reach the alveoli and thus does not participate in gas exchange

Answer 10

Dead Space

Question 11

A process in which molecules move from one area of higher concentration to an area of lower concentration

Answer 11

Diffusion

Question 12

Shortness of breath

Answer 12

Dyspena

Question 13

The passive part of the breathing process in which the diaphragm and the intercostal muscles relax, forcing air out of the lungs

Answer 13

Exhalation

Question 14

A dangerous condition in which the body tissues and cells do not have enough oxygen

Answer 14

Hypoxia

Question 15

A condition in which chronically low levels of oxygen in the blood stimulate the respiratory drive; seen in patients with chronic lung disease

Answer 15

Hypoxic Drive

Question 16

Breathing that requires greater than normal effort; may be slower or faster than normal and usually requires the use of accessory muscles

Answer 16

Labored breathing

Question 17

Space within the chest that contains the heart, major blood vessels, vagus nerve, trachea, major bronchi, and esophagus; Located between the two lungs

Answer 17

Mediastinum

Question 18

Delivers 24% to 44% supplemental oxygen

Answer 18

Nasal Cannula

Question 19

A combination mask and reservoir bag system that is the preferred way to give oxygen in the prehospital setting; delivers up to 90% inspired oxygen and prevents inhaling the exhaled gases (carbon dioxide)

Answer 19

Nonrebreathing Mask

Question 20

The process of delivering oxygen to the blood by diffusion from the alveoli following inhalation into the lungs

Answer 20

Oxygenation

Question 21

Thin membrane that lines the chest cavity

Answer 21

Parietal Pleura

Question 22

Open, clear of obstruction

Answer 22

Patent

Question 23

A partial or complete accumulation of air in the plural space

Answer 23

Pneumothorax

Question 24

Thin membrane that covers the lungs

Answer 24

Visceral Pluera

Question 25

A life threatening collection of air within the pleural space; the volume and pressure have both collapsed the involved lung and caused the shift of the mediastinal structures to the opposite side

Answer 25

Tension Pneumothorax

Question 26

The amount of air (in mL) that is moved in or out of the lungs during one breath

Answer 26

Tidal Volume
