1

what is the sound frequency of a normal lung?

500 hz

2

bronchial breath sounds are ?

sounds air makes when flowing through a tube

3

where do you hear bronchial sounds?

chest/ trachea

4

characteristics of bronchial breath sounds?

high pitch
long expiratory phase
tiny gap between inspiration and expiration

5

vesicular sounds are filtered by

air filled vesicles ( alveoli)

6

where are vesicular breaths heard?

lungs

7

vesicular breath sound characteristics?

low frequency
expiration is short
no pause

8

is it normal to find bronchial breath sounds anywhere other than the neck? if so what does this mean

no
collapsed lung or filled with fluid ( pulmonary edema)

9

are crackle finding in the chest always significant?

yes

10

when are crackles heard

inspiration

11

bronchitis is happens in

early inspiratory

12

how is early inspiratory crackles generated

air flowing through large central bronchi covered in secretions

13

bubbling noise
typically low pitched
called course crackles
often cleared with coughing

early inspiratory crackles

14

comes from small distal airways that are partially collapsed?

late inspiratory crackles

15

fine
high pitched
resemble the undoing of Velcro.

late inspiratory crackles

16

why is there high pressure in the interstitial tissue?

scarring on the lung tissue
fluid in the lungs

17

pulmonary fibrosis, pulmonary hemorrhage, pneumonia, or pulmonary edema are all indications of

late inspiratory crackles

18

high pitched
caused when air flows rapidly through a narrow airway causing the air way to flutter

wheezes

19

if an asthmatic stops breathing does this mean they are in the clear?

no, respiratory failure

20

only people with asthma wheeze

no

21

wheezes will only be

inspiratory and expiratory
just expiratory

22

stridor

wheezing during inspiration only

23

closing of vocal cords

stridor

24

rhonchi

similar to wheezes
lower pitched
longer
snoring quality

25

caused by thick secretions that narrow the airway
diffused over several area of the lung
often localized

rhonchi

26

persistent rhonchus localized to a specific area

neoplasm

27

do you listen to the lungs with the diaphragm or the bell?

diaphragm

28

angle of louis

useful place to start counting ribs

29

space between ribs

intercostal space

30

assessment skills of the lungs

general inspection
chest expansion
tactile fremitus
chest percussion
lung auscultation

31

barrel chest

COPD deep and wide
normal in children

32

pectus excavatum

chest is caved in

33

pectus carinatum

chest stick out

34

kyphosis

hump in back old age
osteoporosis

35

scoliosis

lateral left and right curve of the spine

36

biot respirations

seen in brain injury, heat stroke spinal meningitis
irregular pattern

37

chyene-stoke respiration

respirations gradually wax and wanes in a regular pattern
increasing the decreasing
sever heart failure , renal failure , drug over doese

38

hyperventilation (Kussmaul)

high blood pressure
DKA

39

signs of Respiratory Distress

accessory muscles- torso moving
grunting
head bobbing - babies
retraction
tachypnea
tripod position-leaning forward ,holding knees

40

Chest expansions

hand must equally expand
may seen abnormalities in someone with a punctured lung

41

Tactile Expansion

symmetrical
heel of hand in intercostal space
mass or fluid is an abnormality

42

chest percussion sounds and areas you will hear those sounds

resonance- lung field
tympany- cavity filled with air
dullness- liver
fullness- large muscle mass
