0

The amount of air that reaches the alveoli

Alveolar ventilation

1

Forcing air or oxygen into the lungs when a patient has stopped (or has inadequate) breathing

Artificial ventilation

2

A device that provides positive pressure ventilation, adjustable, portable, and easily carried on an ambulance

Automatic Transport Ventilator (ATV)

3

A handheld device with a face mask and self-refilling bag that can be squeezed to provide artificial ventilation store a patient from atmosphere or supply system

Bag-valve mask (BVM)

4

Exchange of oxygen and carbon dioxide between cells and circulating blood

Cellular respiration

5

Pressure applied to the cricoid right to minimize air entry into the esophagus during positive pressure ventilation

Cricoid pressure

6

A blue or gray color resulting from lack of oxygen

Cyanosis

7

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

Diffusion

8

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

Flow meter

9

A device that uses oxygen under pressure to deliver artificial ventilation. The trigger is placed where the rescuer can operate it while still using both hands to maintain a seal on the facemask. It has automatic flow restriction to prevent over delivery of oxygen to the patient

Flow-restricted, oxygen-powered ventilation device (FROPVD)

10

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

Humidifier

11

An insufficiency of oxygen in the body's tissues

Hypoxia

12

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

Nasal cannula

13

A facemask and reservoir bag device that delivers high concentrations of oxygen. The patients exhaled air escapes through a valve and is not rebreathed

Nonrebreather mask (NRB)

14

A cylinder filled with oxygen under pressure

Oxygen cylinder

15

A face mask and reservoir oxygen bag with no one-way valve to the reservoir bag so that some exhaled air mixes with the oxygen. Used to preserve carbon dioxide levels in the blood to stimulate breathing

Partial rebreather mask

16

A device with a one-way valve to aid in artificial ventilation. The rescuer breathes through the valve when the mask is placed over the patient's face. It provides a barrier between patient's breath and fluids.

Pocket face mask

17

Another term for artificial ventilation

Positive pressure ventilation

18

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

Pressure regulator

19

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

Pulmonary respiration

20

The diffusion of oxygen and carbon dioxide between the alveoli and the blood and between the blood and the cells. Simplified to just mean "breathing."

Respiration

21

When breathing completely stops

Respiratory arrest

22

Increased work of breathing; a sensation of shortness of breath

respiratory distress

23

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

Respiratory failure

24

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

Stoma

25

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

Tracheostomy mask

26

Breathing in and out

Ventilation

27

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

Venturi mask
