Comprehensive Respiratory Exam Guidelines

Oct 1, 2024

Focused Respiratory Exam Notes

Introduction

  • Performing a respiratory exam involves:
    • Observation: Look for symmetry and overall condition of the patient.
    • Palpation: Touching to assess for abnormalities.
    • Commands: Asking the patient to perform certain actions.

Initial Observations

  • Patient Overview:
    • Examine the patient from the inside of the bed for symmetry.
    • Assess patient's build: normal weight, cachectic, or obese.
      • Cachexia: May indicate TB, malignancy, emphysema.
      • Obesity: Could suggest obstructive sleep apnea, COPD.
  • Breathing Assessment:
    • Check for tachypnea (RR>25) suggesting respiratory distress.
    • Look for nasal flaring, pursed lips (COPD), tracheal tug, use of accessory muscles.

Signs of Respiratory Distress

  • Patient may exhibit tripod posture (COPD).
  • Observe for adjuncts like oxygen use, inhalers, or IV lines.

Voice and Chest Movement

  • Listen for stridor, wheezing, or hoarse voice.
  • Check symmetric chest rise and for any precordial deformities.

Hands Examination

  • Fine Tremor: Indication of beta-2 agonist use.
  • Asterexis: Indicates CO2 retention (severe COPD).
  • Muscle Wasting: Suggests Pancoast tumors.
  • Clubbing: Indicative of chronic lung conditions (e.g., lung abscess, bronchiectasis).
  • Peripheral Cyanosis: Check for warm, clammy hands (CO2 retention).

Pulse and Face Examination

  • Pulse: Tachycardia can occur in severe asthma.
  • Cushingoid Features: Chronic steroid use.
  • Plethora: CO2 retention or SVC obstruction.
  • Connective Tissue Disease: Look for manifestations in the face.
  • Conjunctival Pallor: Could suggest chronic illness (malignancy, TB).
  • Horner's Syndrome: Meiosis, ptosis, anhidrosis (apical tumor).

Mouth and Neck Examination

  • Check oral hygiene for signs predisposing to pneumonia.
  • Lymph Nodes: Palpate submental, submandibular, cervical chains, supraclavicular.
  • Tracheal Deviation: Assess for deviation, tracheal tug.

Additional Neck Checks

  • Suprasternal to Cricoid Distance: Indicates hyperinflation if <3 fingers.
  • Jugular Venous Pressure (JVP): Core pulmonale indicator.
  • Edema: Check around the medial malleolus.

Chest Inspection and Palpation

  • Chest Symmetry: Look for asymmetric rise.
  • Scars: Indicate previous surgeries (CABG, pneumonectomy).
  • Deformities: Barrel chest (COPD), pectus excavatum/carinatum.
  • Radiation Tattoos: May indicate past malignancy treatment.
  • Kyphoscoliosis: Check back for deformities.

Palpation Details

  • Costal Chondritis: Palpate for pain along costal margins.
  • Chest Rise Measurement: Should be 5 cm on inhalation.
  • Tactile Fremitus: Useful to differentiate consolidation from pleural effusion.

Percussion Technique

  • Supra Clavicular Area: Start percussion.
  • Resonance: Normal chest should be resonant.
    • Hyper-resonance: Emphysema, bronchitis, pneumothorax.
    • Dullness: Pleural effusion, consolidation.
  • Percuss Entire Chest: Note any deviations from expected resonance.

Auscultation

  • Technique: Use diaphragm for chest, bell for supraclavicular.
  • Breath Sounds: Vesicular is normal, check for wheezing, stridor.
  • Bronchial Breath Sounds: Indicate consolidation if heard in chest.
  • Crackles: Indicate fluid or fibrosis.

Conclusion

  • Comprehensive respiratory exam includes detailed observation, palpation, percussion, and auscultation.
  • Aim to identify any abnormalities that might indicate underlying respiratory conditions.
