Question 1

Breathing in and out, or artificial provision of breaths

Answer 1

Ventilation

Question 2

The amount of air that reaches the alveoli

Answer 2

Alveolar ventilation

Question 3

A process by which molecules move from an area of high concentration to an area of low concentration

Answer 3

Diffusion

Question 4

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

Answer 4

Pulmonary respiration

Question 5

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

Answer 5

Cellular respiration

Question 6

The diffusion of oxygen and carbon dioxide between the alveoli and the blood, and between the blood and the cells

Answer 6

Respiration

Question 7

An insufficiency of oxygen in the body’s tissues

Answer 7

Hypoxia

Question 8

Increased work of breathing; a sensation of shortness of breath

Answer 8

Respiratory distress

Question 9

The inadequacy of breathing to the point where oxygen intake or the ventilation removal of carbon dioxide is not sufficient to support life

Answer 9

Respiratory failure

Question 10

When breathing completely stops

Answer 10

Respiratory arrest

Question 11

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

Answer 11

Cyanosis

Question 12

The use of positive pressure to force air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing

Answer 12

Artificial ventilation

Question 13

Another name for artificial ventilation

Answer 13

Positive pressure ventilation

Question 14

A device, usually with a one-way valve, to aid in artificial ventilation; also acts as a barrier to prevent contact with a patient’s breath or body fluids

Answer 14

Pocket face mask

Question 15

A handheld device with a face mask and self-refilling bag that can be squeezed to provide artificial ventilation to a patient; can deliver air from the atmosphere or oxygen from a supplemental oxygen supply system

Answer 15

Bag-valve mask (BVM)

Question 16

A permanent surgical opening in the neck through which the patient breathes

Answer 16

Stoma

Question 17

A device that provides positive pressure ventilations; includes settings designed to adjust rate and volume, is portable, and is easily carried on an ambulance

Answer 17

Automatic transport ventilator (ATV)

Question 18

A cylinder filled with oxygen under pressure

Answer 18

Oxygen cylinder

Question 19

A device connected to an oxygen cylinder to reduce cylinder pressure so it is safe for delivery of oxygen to a patient

Answer 19

Pressure regulator

Question 20

A valve that indicates the flow of oxygen in liters per minute

Answer 20

Flowmeter

Question 21

A device connected to the flowmeter to add moisture to the dry oxygen coming from an oxygen cylinder

Answer 21

Humidifier

Question 22

A face mask-and-reservoir bag device that delivers high concentrations of oxygen; the patient’s exhaled air escapes through a valve

Answer 22

Nonrebreather (NRB) mask

Question 23

A device that delivers low concentrations of oxygen through two prongs that rest in the patient’s nostrils

Answer 23

Nasal cannula

Question 24

A face mark and reservoir oxygen bag with no one-way valve to the reservoir bag, so some exhaled air mixes with the oxygen; used in some patients to help preserve carbon dioxide levels in the blood to stimulate breathing

Answer 24

Partial rebreather mask

Question 25

A face mask-and-reservoir bag device that delivers specific concentrations of oxygen by mixing oxygen with inhaled air

Answer 25

Venturi mask

Question 26

A device designed to be placed over a stoma or tracheostomy tube to provide supplemental oxygen

Answer 26

Tracheostomy mask
