40
Q

Purpose of ausculation

A
  • To determine whether there is normal air-flow, airway obstruction, or abnormal air or fluid within the chest/lungs
41
Q

Normal breath sounds

A
  • Trachea: heard over trachea
  • Bronchial: heard over manubrium
  • Bronchovesicular: heard in 1st & 2nd interspace anteriorly & btwn scapula posteriorly
42
Q

What should you suspect if bronchial &/or bronchovesicular sounds are heard at distant location?

A

Fluid-filled lung

43
Q

Adventitious sounds

A
  • Crackles
  • Rhonchi
  • Wheeze
44
Q

Crackles (rales)

A
  • Discontinuous
  • Caused by “popping open”of small airways & alveoli that have collapsed.
  • Fluid in lung (E.g. pneumonia, congestive heart failure).
45
Q

Rhonchi

A
  • Low-pitched, continous
  • Snoring quality
  • Caused by airway secretions & narrowing / partial obstruction (E.g. bronchitis, COPD)
46
Q

Wheeze

A
  • Continuous
  • High-pitched, whistle
  • Caused by airway obstruction (E.g. asthma)
47
Q

Pleural effusion

A

Collection of fluid in the pleural space

48
Q

Emphysema

A
  • Pus in pleural space

- Results from infection that spreads from lungs (e.g. pneumonia, abscess)

49
Q

Acute bronchitis

A
  • Inflammation of bronchi (not involving the lungs)

- Bronchi are considered part of the upper airway

50
Q

Asthma

A
  • Bronchial tubes are hyper-responsive
  • Airways become inflamed & produce excess mucus
  • Muscles around airways tighten –> narrower airways –> obstruct breathing
  • Reversible
51
Q

COPD (e.g. emphysema)

A
  • Assoc. w/ airway resistance & residual volume of air after full expiration
  • Can result in hyperinflated lungs –> barrel chest
  • Considered irreversible
52
Q

Pleural friction rub

A
  • Squeaking, grating sound of pleural linings rubbing together
  • Assoc. w/ pleurisy
  • Heard on inspiration & expiration
53
Q

Crepitus

A
  • Palpable grating, crunching
  • Occurs w/ rib movement due to fracture
    (bone crepitus)
54
Q

Tactile fremitus

A
  • Looking for consolidation
  • Vibrations transmitted through bronchopulmonary tree
  • Use ulnar surface of the hand to appreciate palpable vibrations
  • Ask the pt to say “ninety-nine”
55
Q

Increased tactile fremitus

A
  • Consolidation increases transmission (E.g. pneumonia)

- “Solid” transmits sound better than air

56
Q

Decreased tactile fremitus

A
  • Air & effusions decrease transmission (Eg. Pleural effusion, pneumothorax, COPD, fibrosis)
57
Q

Types of crackles

A
- Fine crackles: interstitial process, can 
 be normal
- Medium crackles 
- Coarse crackles: airway disease s/a
  damage to bronchi
58
Q

Mediastinal hunch (Hamman sign)

A
  • Loud crackles, clicks, & gurgling
  • Due to pneumo-mediastinum (mediastinal emphysema)
  • Synchronous w/ heart beat
59
Q

What tests check for consolidation?

A
  • Bronchophony
  • Egophony
  • Whispered pectoriloquy
60
Q

Bronchophony

A
  • “99” heard louder & clearer than normal
  • Indicates presence of fluid or solid tissue in alveoli
  • Ex. pneumonia, atelectasis, tumors
61
Q

Egophony

A
  • When voice sounds are louder, have a nasal quality, & “E” sounds like “A”
  • aka. “E to A sounds”
  • Indicates presence of fluid or solid tissue in alveoli
    Ex. pneumonia, atelectasis, tumors
62
Q

Whispered pectoriloquy

A
  • Whisper heard more loudly through consolidated lung tissue
  • Most noticeable when comparing a normal area of lung to an abnormal area
  • Indicates presence of fluid or solid tissue in alveoli
    Ex. pneumonia, atelectasis, tumors

  • Ask pt to walk down hall or climb 1 flight of stairs 

- Observe rate & effort

68
Q

Forced expiratory time

A
  • Ask pt to “blow out the candles”

- >6 seconds = obstructive pulmonary disease

69
Q

Auscultate during forced exhalation

A

May allow faint wheezes to be heard better
