Questions and Answers

During a physical examination, a patient's tactile fremitus is decreased, and percussion reveals hyperresonance. Auscultation is likely to reveal:

  • Adventitious sounds such as crackles, suggesting fluid in the small airways.
  • Diminished breath sounds, potentially indicating extra air in the pleural space. (correct)
  • Bronchial breath sounds, indicating fluid-filled alveoli.
  • Increased breath sounds, suggesting lung consolidation.

A patient presents with suspected pneumonia in the lower lobe of the right lung. Which combination of findings would most strongly support the diagnosis of lobar consolidation?

  • Decreased tactile fremitus, hyperresonant percussion, diminished breath sounds.
  • Absent tactile fremitus, stony dull percussion, absent breath sounds.
  • Normal tactile fremitus, resonant percussion, vesicular breath sounds.
  • Increased tactile fremitus, dull percussion, bronchial breath sounds. (correct)

In the context of lung auscultation, how would you differentiate between egophony and whispered pectoriloquy, and what underlying lung condition do both typically indicate?

  • Egophony is a coarse, grating sound; whispered pectoriloquy is a fine, crackling sound; both indicate airway constriction.
  • Egophony is a clear, whispered sound; whispered pectoriloquy is 'ee' heard as 'ay'; both indicate pneumothorax.
  • Egophony is a low-pitched wheeze; whispered pectoriloquy is a high-pitched crackle; both indicate pleural effusion.
  • Egophony is 'ee' heard as 'ay'; whispered pectoriloquy is a clear, whispered sound; both indicate lung consolidation. (correct)

Tactile Fremitus

Vibration felt on the chest wall during speech. It indicates the density of underlying lung tissue.

Lung Percussion Sounds

Sound produced by tapping the chest. Dullness suggests density; hyperresonance suggests extra air.

Breath Sound Auscultation

Sounds heard through a stethoscope. Louder sounds indicate consolidation; diminished sounds indicate air or fluid.

Adventitious Sounds

Abnormal lung sounds like crackles (fluid), wheezes (narrowing), or rubs (inflammation).

Study Notes

  • A thoracic exam includes inspection, palpation, percussion, and auscultation

Inspection

  • Note the shape and configuration of the chest
  • Note the facial expression, skin color, respiratory effort, and use of accessory muscles.

Palpation

  • Palpate for symmetric expansion or lag expansion
  • Palpate for tenderness, lumps, turgor, temperature, moisture, and crepitus
  • Assess tactile fremitus or palpable vibration, ask the patient to say "99" or "blue moon" to feel vibrations

Percussion

  • Bilaterally compare sounds when percussing to elicit sounds
  • Percussion sounds include:
    • Dull over the lungs, indicates mass, consolidation, atelectasis, or pleural effusion
    • Resonance, which is normal
    • Hyperresonance,indicates asthma, pneumothorax, or emphysema

Auscultation

  • Bilaterally compare sounds when listening, anteriorly at 8 points, and posteriorly at 6 points
  • Assess breath sounds, adventitious sounds, and voice sounds

Assessing Voice Sounds

  • Bronchophony:
    • Technique: Ask the person to say "ninety-nine" while listening with a stethoscope
    • Normal finding: Voice sounds are soft, muffled, and unclear
    • Abnormal finding: Clear "ninety-nine," words are louder and more distinct
  • Egophony:
    • Technique: Ask the person to say "ee-ee-ee" while listening with a stethoscope
    • Normal finding: Hear "eeee" clearly
    • Abnormal finding: "Eeee" changes to "aaaa" sound, indicating consolidation
  • Whispered Pectoriloquy:
    • Technique: Ask the person to whisper "one-two-three" while listening with a stethoscope
    • Normal finding: Whispered sounds are faint and barely heard
    • Abnormal finding: Whispered "one-two-three" is heard clearly and distinctly, indicating consolidation

Concepts

  • Palpation of Vibration (Tactile Fremitus):
    • Increases when the lung or airways are more solid/consolidated, allowing better vibration conduction,
    • Decreases when there is more air or fluid blocking transmission
  • Percussion:
    • Dull over denser areas (fluid, solid tissue)
    • Hyperresonant (very "hollow") when there is extra air (e.g., emphysema or pneumothorax)
  • Auscultation:
    • Breath sounds are louder/“bronchial” over consolidated lung because sound travels well in solids
    • Breath sounds are diminished when air or fluid separates the lung from the chest wall
  • Adventitious Sounds:
    • Arise from turbulent airflow through fluid-filled or constricted airways (e.g., crackles in fluid, wheezes in narrowed airways, rubs in inflamed pleura)
  • Specific Voice Sounds:
    • Bronchophony: louder "ninety-nine"
    • Egophony: "ee" heard as "ay"
    • Whispered Pectoriloquy: clear whispered sounds like "one, two, three"
    • above are all louder and clearer over areas of lung consolidation.
  • Increased density (e.g., consolidation)
    • ↑ fremitus, dull percussion, bronchial breath sounds.
  • Extra air (pneumothorax or hyperinflation)
    • ↓ fremitus, hyperresonance, ↓ breath sounds
  • Fluid/effusion
    • ↓ fremitus, dullness, ↓ breath sounds
  • Crackles, wheezes, and rubs
    • Arise from fluid in alveoli, narrowed airways, or inflamed pleura

Conditions

  • Normal Lung:

    • Inspection: AP < transverse diameter, relaxed, 10-20 breaths/min
    • Palpation: Symmetric chest expansion, no tenderness
    • Percussion: Resonant
    • Auscultation: Vesicular over periphery, bronchovesicular central
    • Adventitious Sounds: None
    • Voice Sounds:
      • Bronchophony: Muffled (you can't make out distinct words)
      • Egophony: Absent (you hear "eee” as "eee,” not "aaa")
      • Whispered Pectoriloquy: Faint (whispered words aren't distinctly heard)
      • Reason: (Normal air-filled alveoli do not enhance sound conduction)
  • Atelectasis (Collapse):

    • Inspection: Cough, cyanosis, lag on affected side
    • Palpation: ↓ (collapsed area, doesn't transmit vibrations well)
    • Percussion: Dull (less air, relatively more solid tissue)
    • Auscultation: Diministhed/Absent breath sounds, maybe a few crackles if partial reopening
    • Adventitious Sounds: Crackles in partial reopening may be present

      • Bronchophony: Muffled (words not clearly heard)
      • Egophony: Absent (no "eee" → "aaa" change)
      • Whispered Pectoriloquy: Faint (whispered words not distinctly heard)
