    Study Notes

    Anatomy of Respiratory System

    • The respiratory system includes the upper airway (nose, mouth, oropharynx, and larynx) and the lower airway (trachea and lungs).
    • Each lung contains approximately 300 million alveoli, providing a total air exchange surface area of 40-80m2.
    • The left lung has 45% of the total surface area available for gas exchange due to the location of the heart within the left side of the chest.

    Chest Landmarks

    • Anterior Landmarks: Suprasternal notch, Supraclavicular fossa, Infraclavicular fossa, Sternal line, Sternal angle, Parasternal line, Anterior midline, Midclavicular line, Epigastric angle
    • Lateral Landmarks: Posterior axillary line, Anterior axillary line, Midaxillary line
    • Posterior Landmarks: Suprascapular region, Scapular region, Interscapular region, Infrascapular region, Scapular line, Posterior midline

    Respiratory System Examination

    • History of Present Illness:
      • Six cardinal symptoms of chest diseases: cough, expectoration (sputum), hemoptysis, chest pain, dyspnea, wheezes.
    • Cough:
      • Dry or productive.
      • Persistent or episodic.
      • Acute (lasting less than 3 weeks) or chronic (lasting longer).
    • Expectoration (Sputum):
      • Important to note color, consistency, volume, and odor.
      • Can be mucoid, purulent, or blood-tinged.
    • Hemoptysis:
      • Differentiate from hematemesis (vomiting blood).
      • Causes: Mitral stenosis, Pulmonary tuberculosis, Pulmonary infarction, Bronchiectasis, Bronchogenic carcinoma, Bronchial adenoma, Bleeding tendency.
      • Ask about preceding events (e.g., deep vein thrombosis, chest infection).
    • Chest pain:
      • Common and the location and character of pain can indicate specific diseases.
      • Retrosternal pain: acute tracheitis.
      • Mediastinal pain: emphysema or mediastinitis.
    • Dyspnea:
      • Difficulty or labored breathing.
      • Causes: Emphysema, Asthma, Pneumonia, Pneumothorax, Pleural effusion.
    • Wheezes:
      • Differentiate between wheezes and stridor.
      • Wheezes occur due to narrowing of small airways.
      • Stridor occurs due to obstruction of major airways and is audible only during inspiration.
      • Wheezing can be intermittent (asthma) or persistent (chronic bronchitis).
      • Wheezing can be diffuse (asthma, chronic bronchitis) or localized (bronchogenic carcinoma).

    Examination Techniques

    • Inspection:
      • Observe from the end of the bed:
        • Respiratory rate, chest shape, oxygen, inhalers/nebulisers, sputum pot, cigarettes, stridor, cachexia, accessory muscle use, pursed lip breathing.
      • Examine Hands:
        • Clubbing, tar staining, tremor, asterixis, steroidal skin, wasting of small muscles, pulse, hypertrophic pulmonary osteoarthropathy (HPOA).
      • Examine Face:
        • Pallor, dilated pupils, central cyanosis, Horner’s syndrome, Cushingoid appearance, hoarse voice.
      • Examine Neck:
        • Trachea, crico-sternal distance, jugular venous pressure (JVP), lymphadenopathy.
      • Examine Anterior Chest:
        • Inspect for: prominent veins, pulsations, scars, respiratory rate, type of respiration, shape of the chest, any chest deformities, symmetry of chest movement.
    • Palpation:
      • Palpate for: vocal fremitus, tenderness, crepitations, palpable lung edge.
    • Percussion:
      • Done to assess the density of underlying lung tissue.
      • Normal percussion sounds: resonant or hyperresonant. Abnormal percussion sounds: dullness, tympany, flatness.
    • Auscultation:
      • Listen to breath sounds, adventitious sounds, and vocal resonance.

    Respiratory Diseases

    • Pleural Effusion:
      • A buildup of fluid in the space between the lungs and the chest wall (pleural space).
      • Symptoms: Dyspnea, orthopnea, palpitation.
      • Signs (Moderate to massive effusion): tachypnea, limited movement of affected side, wider costal interspaces on affected side, trachea shifts to opposite side, decreased vocal fremitus, dullness or flatness, decreased or disappeared vesicular breath sound, decreased or disappeared vocal resonance, pleural friction rub, abnormal bronchial breath sound in the upper area of the fluid.
    • Pneumothorax:
      • A collapsed lung.
      • Symptoms: Sudden chest pain, dyspnea, forced sitting position, unaffected side lying, dry cough.
      • Signs: Wider costal interspaces on affected side, limited movement of affected side, decreased or disappeared vocal fremitus, trachea and heart shift to opposite side, tympany, vesicular breath sound.
