Chapter 10 Respiration And Artificial Ventilation

Front 1

alveolar ventilation

Back 1

the amount of air that reaches the alveoli

Front 2

artificial ventilation

Back 2

forcing air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing

also called positive pressure ventilation

Front 3

automatic transport ventilator

Back 3

a device that provides positive pressure ventilations

it includes settings designed to adjust ventilation rate and volume, is portable, and is easily carried on an ambulance

Front 4

bag valve mask

Back 4

a handheld device with a face mask and self refilling bag that can be squeezed to provide artificial ventilations to a patient

it can deliver air from the atmosphere or oxygen from a supplemental oxygen supply

Front 5

cellular respiration

Back 5

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

Front 6

cyanosis

Back 6

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

Front 7

diffusion

Back 7

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

Front 8

flowmeter

Back 8

a valve that indicates the flow of oxygen in leters per minute

Front 9

flow restricted, oxygen powered ventilation device

Back 9

a device that uses oxygen under pressure to deliver artificial ventilations

its trigger is placed so the rescuer can operate it while still using both hands to maintain a seal on the face mask

it has automatic flow restriction to prevent overdelivery of oxygen to the patient

Front 10

humidifier

Back 10

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

Front 11

hypoxia

Back 11

an insufficiency of oxygen in the body's tissues

Front 12

nasal cannula

Back 12

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

Front 13

nonrebreather mask

Back 13

a face mask and reservoir bag device that delivers high concentrations of oxygen

the patient's exhaled air escapes through a valve and is not rebreathed

Front 14

oxygen cylinder

Back 14

a cylinder filled with oxygen under pressure

Front 15

partial rebreather mask

Back 15

a face mask 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

Front 16

pocket face mask

Back 16

a device, usually with a one way valve to ad in artificial ventilation

a rescuer breathes through the valve when the mask is placed over the patient's face

is also acts as a barrier to prevent contact with a patient's breath or body fluids

it can be used with supplemental oxygen when fitted with an oxygen inlet

Front 17

pressure regulator

Back 17

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

Front 18

pulmonary respiration

Back 18

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

Front 19

respiration

Back 19

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

also used to mean, simply, breathing

Front 20

respiratory arrest

Back 20

when breathing completely stops

Front 21

respiratory distress

Back 21

increased work of breathing; a sensation of shortness of breathes

Front 22

respiratory failure

Back 22

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

Front 23

stoma

Back 23

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

Front 24

tracheostomy mask

Back 24

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

Front 25

ventilation

Back 25

breathing in and out or artificial provision of breaths

Front 26

venturi mask

Back 26

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

Front 27

an active process

Back 27

inhalation

Front 28

at what stage of breathing is there negative pressure in the chest

Back 28

inhalation

Front 29

a passive process

Back 29

exhalation

Front 30

at what stage of breathing is there positive pressure in the chest

Back 30

exhalation

Front 31

normal tidal volume

Back 31

5-7 mL per kg of body weight

Front 32

ventilation

Back 32

breathing in and out

Front 33

alveolar ventilation

Back 33

the amount of air that reaches the alveoli

Front 34

minute volume

Back 34

the amount of air moved inot and out of the lungs in one minute

Front 35

the exchange of gas in the alveoli

Back 35

air moves into the alveoli; the pulmony capillaries transport the blood, and diffusion occurs

Front 36

the movement of oxygen and carbon dioxide across the cell membranes from the capillaries is called:

Back 36

internal respiration

Front 37

nonrebreather mask

Back 37

flow rate 12-15 liters per minute

oxygen concentration 80-90 percent

Front 38

nasal cannula

Back 38

flow rate 1-6 liters per minute

oxygen concentration 22-44 percent

Front 39

partial rebreather mask

Back 39

flow rate 9-10 liters per minute

oxygen concentration 40-60 percent

Front 40

venturi mask

Back 40

flow rate varied depending on device up to 15 liters per minute

oxygen concentration 24-60 percent

Front 41

tracheostomy mask

Back 41

flow rate 8-10 liters per minute

oxygen concentration can be set up as required by the patient
