Flashcards in Chapter 16 Vocab Deck (32)
1

Alveolar ventilation

volume of air that actually reaches air sacs each minute

2

Automatic transport ventilator (ATV)

device that enables hands-free PPV through advanced airway

3

Bag-valve-mask device

manual piece of equipment used to deliver artificial ventilations through a mask with a bag

4

Bronchoconstriction

narrowing of the bronchiolar passageway

5

Capnography

measurement and graph over time of CO2 level in exhaled air sample

6

Capnometry

measurment of the level of CO2 in exhaled air

7

Continuous positive airway pressure (CPAP)

device that delivers constant increased air pressure to airway

8

Flow-restricted oxygen powered ventilation device (FROPVD)

High pressure O2 delivery system that is manually triggered to provide PPV

9

French units (Fr.)

unit of measuring the diameter of medical devices such as suction or catheters. 1 Fr. = .33mm

10

Head-tilt/chin-lift maneuver

technique used to manually position the head and jaw to open airway

11

Hypercapnia

increased level of CO2 in blood

12

Hypocapnia

decreased level of CO2 in blood

13

Hypoxia

decreased level of O2 at cellular level

14

Laryngospasm

involuntary closure of vocal cords over glottis

15

Minute volume

amount of air moved in and out lungs each minute. TV x RR = MV

16

Modified jaw-thrust maneuver

technique used to manually position the jaw to open the airway in pts with suspected C-spine injury

17

Nasopharyngeal airway

short tube inserted through nose so that bevel rests in the pharynx to prevent tongue from occluding airway.

18

Oropharyngeal airway

Curved plastic device inserted in mouth that prevents tongue from occluding airway

19

Peak expiratory flow rate (PERF)

maximal rate that air can be forcefully exhaled from lungs, measured in L/M

20

Peak flow meter

device to measure maximum expiratory flow rate

21

Positive end-expiratory pressure (PEEP)

maintaining positive pressure in airway during expiration to prevent alveoli collapse

22

Positive pressure ventilation (PPV)

artificial ventilation by forcing air into airway

23

Pulmonary edema

interstitial fluid in lungs creating greater diffusion distance for O2 and CO2 across respiratory membrane

24

Pulse oximetry

measure of O2 saturation on hemoglobin using infrared light

25

Relatively contraindicated

situation where a treatment is not usually advised, but where positives outweigh risks

26

Spirometry

measurement of various lung volumes and flow rates

27

Tracheostomy

surgical opening in the trachea to establish airway

28

Trauma chin lift

technique used to displace the mandible anteriorly to open airway w/out hyperextending C-spine

29

Tripod position

position where pt leans forward, supporting himself with his arms from respiratory distress

30

Ventilation

movement of air in and out of lungs

31

Ventilation-perfusion mismatch

condition where either pulmonary circulation or alveolar ventilation is impaired

32

Yankauer

hollow, rigid device that attaches to suction tubing to allow suctioning of oropharynx
