Inspection of the Respiratory System (Concise)
General Survey:
Observe for respiratory distress, use of accessory muscles, posture, and presence of oxygen devices or inhalers around the patient.Hands and Nails:
Look for cyanosis, clubbing (loss of Schamroth’s window), tar staining, and other signs of chronic respiratory disease.Face and Mouth:
Inspect for central cyanosis (bluish lips/tongue), plethoric complexion (polycythemia/CO₂ retention), conjunctival pallor (anemia), and oral candidiasis (steroid inhaler use).Chest Inspection:
Shape: Note any deformities (barrel chest, pectus excavatum/carinatum, kyphosis, scoliosis).
Symmetry: Compare both sides for equal movement.
Trachea & Apex Beat: Check for visible deviation or displacement.
Chest Movements: Assess for reduced or asymmetrical movement in all areas (supraclavicular, infraclavicular, mammary, axillary, scapular, etc.).
Other Findings: Look for dilated veins, scars, sinuses, intercostal indrawing, supraclavicular hollowing, infraclavicular flattening, drooping of shoulder, alar flaring, and use of accessory muscles.
Additional Clues:
Observe for signs of chronic illness (weight loss, muscle wasting), respiratory rate and rhythm, and any abnormal breathing patterns (e.g., Cheyne-Stokes, Kussmaul’s).
Inspection in a Patient with Bronchiectasis
General Appearance:
Patient may appear chronically ill, with evidence of weight loss or muscle wasting in advanced cases.Hands:
Look for digital clubbing, a classic sign in bronchiectasis, especially in long-standing disease.Face and Mouth:
Check for central cyanosis (bluish lips/tongue) indicating hypoxemia, and signs of chronic respiratory distress.Chest:
Shape: Chest is usually normal in shape, but may show mild deformities if disease is severe or longstanding.
Symmetry: Inspect for symmetry of chest movement. In localized or severe disease, reduced movement may be seen over the affected area.
Chest Movements: Observe for reduced or asymmetrical chest expansion, particularly in the lower zones (where bronchiectasis is often most pronounced).
Trachea and Apex Beat: Usually central, but may be displaced in cases with significant volume loss or fibrosis.
Other Findings:
Look for surgical scars (from previous interventions), dilated veins (rare), sinuses, or evidence of previous chest drains.
Note any intercostal indrawing or use of accessory muscles in severe disease.
Crowding of ribs, supraclavicular hollowing, or infraclavicular flattening may be seen if there is significant volume loss.
Respiratory Effort:
Observe for tachypnea, use of accessory muscles, alar flaring, or pursed-lip breathing in advanced or exacerbated cases.Bedside Clues:
Sputum pot with copious, purulent, often foul-smelling sputum may be present, reflecting the hallmark productive cough of bronchiectasis.
Summary of Key Inspection Findings in Bronchiectasis:
Digital clubbing
Copious sputum production (often visible at bedside)
Possible central cyanosis
Reduced chest movement over affected areas
Signs of chronic illness (weight loss, muscle wasting)
Chest wall deformities or scars in advanced/treated cases
Inspection of the Respiratory System in a Patient with COPD
General Appearance:
The patient may appear thin, with muscle wasting, and may adopt a “tripod” position (leaning forward, supporting themselves with their arms) to ease breathing. Signs of respiratory distress such as tachypnea and pursed-lip breathing may be present.Hands and Face:
Look for peripheral cyanosis (bluish discoloration of lips and fingers) due to hypoxemia. Nicotine staining may be seen on the fingers. Clubbing is generally absent in COPD but may be present if there is co-existing bronchiectasis or lung cancer.Chest Shape:
The chest is often barrel-shaped (increased anteroposterior diameter). Intercostal spaces may appear widened.
There may be supraclavicular hollowing and flattening of the infraclavicular region in severe cases.Symmetry and Movement:
Observe for reduced chest expansion, often bilaterally and symmetrically. In advanced disease, lower chest movement may be particularly diminished.Trachea and Apex Beat:
The trachea is usually central unless there is significant lung volume loss or hyperinflation. The apex beat may be difficult to localize due to hyperinflated lungs.Accessory Muscles:
Prominent use of accessory muscles of respiration (sternocleidomastoid, scalene) is common, especially during exacerbations.Other Findings:
Intercostal indrawing (recession) may be seen during inspiration.
Alar flaring (nostril flaring) may be present in severe respiratory distress.
Look for surgical scars (from previous interventions), dilated veins, or chest wall deformities.
Cyanosis and evidence of right heart failure (pedal edema, raised JVP) may be seen in advanced cases.
Bedside Clues:
Presence of inhalers, nebulizers, or oxygen equipment at the bedside.

General Inspection
Q1. What are the main points to look for during inspection of the chest in a respiratory case?
A: Shape of the chest, symmetry, position of trachea, apex beat, chest movement in all areas, presence of dilated veins, scars, sinuses, crowding of ribs, supraclavicular hollowing, infraclavicular flattening, drooping of shoulder, use of accessory muscles, alar flaring, and intercostal in-drawing.
Bronchiectasis
Q2. What are the typical inspection findings in a patient with bronchiectasis?
A: Digital clubbing, possible cyanosis, normal or mildly deformed chest shape, reduced movement in the lower zones (especially infrascapular and infraaxillary), possible old surgical scars, and sputum pot with copious purulent sputum.
Q3. Why is clubbing seen in bronchiectasis?
A: Due to chronic hypoxia and long-standing suppurative lung disease.
Pleural Effusion
Q4. What inspection findings suggest pleural effusion?
A: Fullness or bulging of the affected hemithorax, asymmetry, reduced or absent chest movement on the affected side, possible tracheal and apex beat shift to the opposite side, crowding of ribs, and in chronic cases, drooping of the shoulder or dilated veins.
Q5. Why is chest movement reduced in pleural effusion?
A: Because the fluid in the pleural space restricts lung expansion on the affected side.
Pneumonia
Q6. What do you expect to find on inspection in a case of pneumonia?
A: Usually normal chest shape, but reduced movement over the affected area, use of accessory muscles or intercostal in-drawing in severe cases, and generally central trachea and apex beat.
Q7. Why is chest movement reduced over the affected area in pneumonia?
A: Due to local consolidation and inflammation, which restricts lung expansion.
Lung Cavity
Q8. What inspection findings are seen in a patient with a lung cavity?
A: Localized flattening or retraction, reduced movement in the upper zones, possible supraclavicular hollowing, infraclavicular flattening, crowding of ribs, old surgical scars, and tracheal/apex beat deviation towards the affected side if there is fibrosis.
Q9. Why might there be supraclavicular hollowing in lung cavity disease?
A: Due to volume loss and fibrosis, especially in upper lobe disease.
Pulmonary Fibrosis
Q10. What are the main inspection findings in pulmonary fibrosis?
A: Flattened or retracted chest (especially lower zones), reduced and asymmetrical chest movement, tracheal and apex beat shift towards the affected side, crowding of ribs, supraclavicular hollowing, infraclavicular flattening, and sometimes scars from previous interventions.
Q11. Why does the trachea shift towards the side of fibrosis?
A: Due to volume loss and contraction of the affected lung tissue.
Accessory Muscles and Other Signs
Q12. When do you see use of accessory muscles during inspection?
A: In conditions causing increased work of breathing, such as severe COPD, asthma exacerbation, advanced fibrosis, or respiratory distress of any cause.
Q13. What is intercostal in-drawing and when is it seen?
A: It is the inward movement of intercostal spaces during inspiration, seen in severe airway obstruction or increased negative intrathoracic pressure.
General Integration
Q14. How do you differentiate between volume loss and volume gain on inspection?
A: Volume loss (fibrosis, collapse) shows flattening, retraction, rib crowding, and shift of trachea/apex beat towards the lesion. Volume gain (effusion, pneumothorax) shows fullness, bulging, rib spacing, and shift away from the lesion.
Q15. Why is it important to inspect the entire chest in all zones?
A: Because different diseases affect different areas (e.g., fibrosis often lower zones, cavities upper zones, effusion lower lateral), and comparing all zones helps localize and characterize pathology.
