Here is the detailed IPPA (Inspection, Palpation, Percussion, Auscultation) table for all eight conditions, compiled from Murray & Nadel's Textbook of Respiratory Medicine (Table 18.4), Textbook of Family Medicine (Table 16-2), Harrison's Principles of Internal Medicine 22E, Goldman-Cecil Medicine, and supplemented with findings from Davidson's and Hutchinson's classical descriptions.
Respiratory Examination Findings: IPPA Table
Sources: Murray & Nadel's Textbook of Respiratory Medicine (Table 18.4, 2-Vol Set); Harrison's Principles of Internal Medicine 22E (2025); Goldman-Cecil Medicine; Textbook of Family Medicine 9e (Table 16-2); Hutchinson's Clinical Methods; Davidson's Principles & Practice of Medicine.
Legend for Vocal Resonance / Fremitus Terms
- Tactile Vocal Fremitus (TVF): Vibrations felt on the chest wall when the patient says "99"
- Vocal Resonance (VR): Sounds heard via stethoscope when patient speaks
- Bronchophony: VR sounds abnormally loud and clear
- Egophony (E→A): "Eeee" heard as "Aaay" - hallmark of consolidation
- Whispering Pectoriloquy: Whispered syllables heard clearly through stethoscope
1. Consolidation (Pneumonia)
| Feature | Findings |
|---|---|
| INSPECTION | - Affected side may show lag/splinting on inspiration (due to pleuritic pain) - Reduced chest expansion on affected side - Tachypnoea, tachycardia - Cyanosis in severe cases - Fever (flushed appearance) - Herpes labialis may be present (Streptococcus pneumoniae) |
| PALPATION | - Increased tactile vocal fremitus (TVF) on affected side - Key distinguishing feature from effusion - Reduced chest expansion on affected side - Trachea central (no mediastinal shift) - Apex beat in normal position |
| PERCUSSION | - Dullness to percussion over the consolidated lobe - Not as stony dull as effusion - Resonant elsewhere |
| AUSCULTATION | - Bronchial (tubular) breath sounds over affected area - Bronchophony (loud, clear voice sounds) - Whispering pectoriloquy - Egophony (E→A change) - Coarse inspiratory crackles (due to secretions in airways) - Pleural friction rub may be present if pleuritis - Reduced vesicular breath sounds around periphery of consolidation |
Murray & Nadel Table 18.4: "Possible lag or splinting; increased fremitus on affected side; dullness; bronchial breath sounds, bronchophony, pectoriloquy, crackles."
2. Lung Fibrosis (Interstitial Pulmonary Fibrosis / ILD)
| Feature | Findings |
|---|---|
| INSPECTION | - Digital clubbing (present in ~50-70% of IPF cases) - Cyanosis (central, in advanced disease) - Tachypnoea at rest or on exertion - Signs of right heart failure (cor pulmonale): raised JVP, ankle oedema - Wasting in advanced disease - Respiratory rate elevated |
| PALPATION | - Reduced chest expansion bilaterally (typically bibasal) - TVF may be normal or slightly reduced - Trachea central - Parasternal heave if pulmonary hypertension develops - Loud P2 on palpation at left sternal edge |
| PERCUSSION | - Usually resonant (unlike consolidation or effusion) - May be slightly reduced resonance at bases in advanced disease - No dullness unless secondary effusion develops |
| AUSCULTATION | - Fine end-inspiratory "Velcro" crackles - bilateral, basal, persistent, not cleared by coughing - Heard best in axillae and posterior bases - No wheeze (unless coexisting airways disease) - Bronchial breathing absent - In late/end-stage: crackles throughout, signs of pulmonary hypertension (loud P2, right heart failure sounds) |
Goldman-Cecil: "Physical examination usually reveals digital clubbing and basal crackles on lung auscultation." Murray & Nadel: "Inspiratory Velcro-like crackles... clubbing and other findings associated with fibrotic ILD."
3. Bronchiectasis
| Feature | Findings |
|---|---|
| INSPECTION | - Digital clubbing (characteristic - due to chronic hypoxia and infection) - Copious purulent sputum (patient may expectorate during examination) - Tachypnoea - Cyanosis (in advanced disease) - Signs of malnutrition/chronic illness - Barrel chest if co-existing emphysema - Sputum: 3-layered (frothy top, mucopurulent middle, dense sediment bottom) |
| PALPATION | - Reduced chest expansion over affected areas - TVF may be increased (if consolidation present) or normal - Trachea central unless lobar collapse complicates - Coarse palpable vibrations (rhonchi) may be felt |
| PERCUSSION | - Usually resonant - Dull if consolidation, collapse or fibrosis supervenes - May be hyperresonant if air trapping coexists |
| AUSCULTATION | - Coarse inspiratory and expiratory crackles - most prominent over affected lobes - Change in character with coughing (important differentiating feature) - May partially clear after coughing - Wheeze (if associated airways obstruction) - Bronchial breath sounds if consolidation develops - Reduced breath sounds over severely destroyed lung segments |
Murray & Nadel (clubbing section): "Clubbing has been found in... bronchiectasis." Goldman-Cecil: Bronchiectasis associated with hemoptysis, clubbing, and crackles.
4. Pleural Effusion
| Feature | Findings |
|---|---|
| INSPECTION | - Lag on affected side during inspiration - Increased size of hemithorax (if large) - Fullness of intercostal spaces (ICS) - Trachea and tracheal deviation away from affected side (large effusion) - Tachypnoea - Cyanosis if large - Signs of underlying cause: signs of malignancy, CCF, cirrhosis (spider naevi, etc.) |
| PALPATION | - Decreased/absent TVF over effusion (fluid damps vibration) - Reduced chest expansion on affected side - Trachea shifted AWAY from affected side (large effusion) - Stony dull on percussion confirms effusion - Apex beat shifted away if large left-sided effusion |
| PERCUSSION | - Stony dull (absolute dullness - the dullest of all dull notes) - Shifting dullness if very large (not commonly tested in this way) - Upper border: classically shows a curved "Damoiseau's line" (Ellis-Damoiseau line) - Skodaic resonance: paradoxical resonance above the effusion (due to compression atelectasis of the lung above) |
| AUSCULTATION | - Absent breath sounds over effusion - Reduced/absent vocal resonance below upper border - Aegophony (E→A change) just ABOVE the upper margin of effusion (compressive atelectasis zone) - Pleural friction rub may be heard before effusion fully forms - Bronchial breathing may be heard at the upper border of effusion (if lung compressed) |
Murray & Nadel Table 18.4: "Lag on affected side, increased hemithorax size; decreased fremitus, trachea and heart shifted away; dullness or flatness; absent breath sounds."
5. Pneumothorax
| Feature | Findings |
|---|---|
| INSPECTION | - Lag on affected side - Increased size of hemithorax on affected side - Reduced/absent chest wall movement on affected side - Tracheal deviation: central in small PTX; shifted away from affected side in tension PTX - Distended neck veins (tension PTX) - Respiratory distress, tachycardia, hypotension (tension PTX) - Subcutaneous emphysema may be visible |
| PALPATION | - Absent TVF on affected side - Reduced chest expansion on affected side - Trachea deviated AWAY from affected side in tension PTX - Subcutaneous emphysema (crepitus) on palpation of chest wall/neck |
| PERCUSSION | - Hyperresonant or tympanitic note on affected side - Important: more hyper-resonant than normal, even tympanitic (drum-like) - Decreased liver/cardiac dullness on the affected side |
| AUSCULTATION | - Absent/grossly reduced breath sounds on affected side - Absent vocal resonance - No adventitial sounds over affected side - Contralateral side: normal breath sounds, possibly compensatory hyperventilation - Mediastinal crunch (Hamman's sign) if pneumomediastinum coexists |
Murray & Nadel Table 18.4: "Lag on affected side, increased hemithorax; absent fremitus; hyperresonant or tympanitic; absent breath sounds."
6. Hydropneumothorax
| Feature | Findings |
|---|---|
| INSPECTION | - Affected hemithorax enlarged - Lag on affected side - Tachypnoea, respiratory distress - Tracheal deviation possible - Signs of underlying cause (e.g., empyema, malignancy, trauma) |
| PALPATION | - Absent TVF over the air-containing upper portion - Absent TVF over the fluid-containing lower portion - Trachea may be deviated away if large - Chest expansion reduced on affected side - A "succussion splash" may be felt (rarely) |
| PERCUSSION | - Unique: Two levels of percussion note on the same side - Upper zone: Hyperresonant/tympanitic (air above fluid) - Lower zone: Stony dull (fluid below) - Horizontal upper border of dullness (unlike the curved Damoiseau's line of pure effusion) - This horizontal air-fluid level is pathognomonic |
| AUSCULTATION | - Absent breath sounds throughout affected side - Amphoric/coin sound (tinkling, metallic) may be heard - "Hippocratic succussion splash": a splashing sound heard when the patient's chest is shaken - heard with stethoscope or directly at the ear - Metallic breath sounds occasionally |
Classical teaching (Hutchinson's/Macleod's): The horizontal air-fluid interface giving a tympanitic upper zone and stony dull lower zone is the defining feature. Succussion splash is pathognomonic.
7. Collapse of Lung (Atelectasis)
| Feature | Findings |
|---|---|
| INSPECTION | - Lag on affected side - Decreased size/flattening of hemithorax (opposite to effusion and PTX) - Intercostal spaces narrowed on affected side - Tracheal deviation TOWARD affected side - Cardiac apex shifted toward affected side (if large lobe or whole lung collapse) - Tachypnoea - Signs of underlying cause (e.g., malignancy, foreign body, mucus plug) |
| PALPATION | - Decreased TVF (airless, collapsed lung transmits poorly) - Trachea shifted TOWARD affected side - Reduced chest expansion on affected side - Apex beat shifted toward affected side |
| PERCUSSION | - Dull to percussion over collapsed area - Dullness is due to airless tissue (not fluid as in effusion) - Not stony dull (unlike effusion) |
| AUSCULTATION | - Absent or markedly reduced breath sounds over collapsed area - Absent vocal resonance - No bronchial breathing (airway often obstructed) - If partial obstruction: wheeze may be heard (monophonic, unilateral) - Post-obstructive pneumonia may add crackles |
Murray & Nadel Table 18.4: "Lag on affected side; decreased fremitus, trachea and heart shifted TOWARD affected side; dullness or flatness; absent breath sounds." - Key differentiator from effusion: mediastinal shift is TOWARD in collapse, AWAY in effusion.
8. COPD & Asthma
| Feature | COPD (Emphysema dominant) | Asthma (Acute Attack) |
|---|---|---|
| INSPECTION | - Barrel chest (increased AP diameter, AP:lateral ratio approaches 1:1) - Use of accessory muscles (sternomastoid, scaleni) - Pursed-lip breathing (auto-PEEP mechanism) - Hoover's sign: paradoxical inward movement of lower ribs on inspiration - Cyanosis (central, in Type B/blue bloater) - Tripod position (sitting forward, hands on knees) - Tracheal tug - Loss of Cricosternal distance (<3 cm) - Wasting, cachexia in severe COPD - Ankle oedema (cor pulmonale) | - Hyperinflation: visibly over-inflated chest - Use of accessory muscles - Intercostal and subcostal recession (children) - Tachypnoea, tachycardia - Pulsus paradoxus (>10 mmHg in severe attack) - Pursed-lip breathing - Cyanosis (severe/life-threatening) - Inability to speak in sentences (severity marker) - Silent chest = ominous, near-fatal - Prolonged expiratory phase |
| PALPATION | - Reduced/impaired chest expansion bilaterally - Decreased TVF (hyperinflated, air trapping) - Low flat diaphragm - Trachea central or slightly deviated - Reduced cricosternal distance - Loss of liver/cardiac dullness borders - Tachycardia may be felt - RV heave (cor pulmonale) | - Impaired chest expansion bilaterally - Decreased TVF - Trachea central - Low diaphragm position - Tachycardia - Pulsus paradoxus (pulse volume decreases on inspiration) |
| PERCUSSION | - Hyperresonance bilaterally - Loss of cardiac dullness (situs solitus but hidden by hyperinflated lung) - Loss of hepatic dullness (liver pushed down) - Low flat diaphragm with poor excursion (<3 cm) - Chest resonates "like an empty box" | - Hyperresonance bilaterally - Low diaphragm (hyperinflation) - Resonance throughout (uniform) |
| AUSCULTATION | - Markedly reduced breath sounds ("quiet chest") - Prolonged expiratory phase - Expiratory wheeze (polyphonic) - Coarse crackles in infective exacerbations - Wheeze reduced in very severe hyperinflation - Coarse crackles if chronic bronchitis component (mucus hypersecretion) - Distant heart sounds | - Bilateral expiratory wheeze (polyphonic, high-pitched) - May have inspiratory wheeze too - Prolonged expiration - In life-threatening attack: silent chest (no wheeze = no air movement = emergency) - Tachycardia - Absent breath sounds with silent chest = near-fatal |
Murray & Nadel Table 18.4: "Bronchial asthma (acute exacerbation): Hyperinflation; use of accessory muscles; impaired excursion, decreased fremitus; hyperresonance, low diaphragm; prolonged expiration: inspiratory and expiratory wheezes."
Quick Differentiating Summary Table
| Condition | TVF | Percussion | Breath Sounds | Trachea |
|---|---|---|---|---|
| Consolidation | ↑ Increased | Dull | Bronchial + crackles | Central |
| Lung Fibrosis | Normal/↓ | Resonant | Fine Velcro crackles | Central |
| Bronchiectasis | Normal/↑ | Resonant | Coarse crackles ± wheeze | Central |
| Pleural Effusion | ↓ Decreased | Stony dull | Absent | Away from lesion |
| Pneumothorax | Absent | Hyper-resonant/Tympanitic | Absent | Away (tension) |
| Hydropneumothorax | Absent | Upper: tympanitic / Lower: stony dull | Absent ± succussion splash | Away |
| Lung Collapse | ↓ Decreased | Dull | Absent | Toward lesion |
| COPD/Emphysema | ↓ Decreased | Hyper-resonant | Reduced + wheeze | Central |
| Asthma (acute) | ↓ Decreased | Hyper-resonant | Wheeze/silent chest | Central |
Key Mnemonics
For effusion vs. consolidation: "Effusion FLATtens (absent breath sounds, decreased TVF, flat/stony dull) - Consolidation CONverges everything (bronchial breathing, increased TVF, dullness)"
Tracheal shift: "Effusion and Pneumothorax PUSH the trachea away; Collapse and Fibrosis PULL the trachea toward"
Hydropneumothorax: "Top = air = tympanitic; Bottom = fluid = stony dull; Shake = splash (succussion)"
