Flashcards in Respiratory Assessment Deck (32):
1

Respiration

Gas exchange between alveoli and blood capillaries

2

Ventilation

Movement of air in and out of lungs

3

Perfusion

Process where oxygenated blood passes through tissue

4

Hypoxia

Inadequate amount of oxygen is available to cells

5

Hypoventilation

Decreased rate or depth of air movement into lungs

6

Eupnea

Normal breathing

7

Dyspnea

Labored respiration

8

Orthopnea

Ability to breathe easy only in upright position

9

Apnea

Absence of breathing

10

Tachypnea

Fast breathing

11

Bradypnea

Slow breathing

12

Depth

Shallow versus deep

13

Rhythm

Regular vs irregular

14

Cheyenne stokes respiration

Alternating periods of deep rapid breathing followed by periods of apnea

15

Biots respiration

Varying rate and depth of breathing followed by periods of apnea

16

Kussmauls respiration

Deep gasping breaths with respiratory rate greater than 20 breaths/min

17

Factors affecting respiratory rate

Age
Gender
Exercise
Brain lesions
Anemia
Medication

18

Upper air way

Nose pharynx larynx epiglottis

19

Lower air way

Trachea mainstem bronchi cilia

20

Lungs

Right lung: 3 lobes
Left lung: 2 lobes

21

Surfactant

Surface tension- present alveoli from collapse

22

Pleura

Serous membrane lines the lung

23

Visceral

Covers lung

24

Normal breath sounds

Bronchial
Bronchovesicular
Vesicular

25

Bronchial sounds

Loud high pitch, over trachea/larynx expectation longer than inspiration

26

Bronchovesicular sound

Blowing sound medium over lungs E=I

27

Vesicular sound

Low pitch over periferal lung I>E

28

Abnormal sounds

Stridor
Crackles
Rhonchi
Wheezes
Pleural friction rub

29

Stridor

Harsh high pitch sounds on inspiration upper airway

30

Crackles

Soft high pitch piping noise air to wet secretion

31

Rhonchi

Low pitch core sound coughing clear sound

32

Wheezes

Continuous musical sounds
