Study Notes
COPD Diagnosis and Management
- COPD diagnosis is confirmed by spirometry, which is required to make a diagnosis.
- The presence of a post-bronchodilator FEV1/FVC < 70% confirms the presence of persistent airflow limitation.
Initial Assessment
- Once COPD is diagnosed, the assessment must focus on determining four fundamental aspects:
- Severity of airflow limitation
- Nature and magnitude of current symptoms
- Previous history of moderate and severe exacerbations
- Presence and type of other diseases (multimorbidity)
Treatment for COPD
- For a patient with a Modified Medical Research Council Dyspnea Scale score of 1, the Global Initiative for Chronic Obstructive Lung Disease recommends a long-acting muscarinic antagonist (LAMA) monotherapy.
- Other treatment options include:
- Inhaled corticosteroid (ICS) monotherapy
- Long-acting beta2 agonist (LABA) monotherapy
- Short-acting beta2 agonist monotherapy
COPD Exacerbation
- An exacerbation of COPD is defined as an event characterized by dyspnea and/or cough and sputum that worsen over < 14 days.
- Exacerbations are often associated with increased local and systemic inflammation caused by airway infection, pollution, or other insults to the lungs.
- Recovery time from an exacerbation varies, taking up to 4-6 weeks to recover, with some patients failing to return to the pre-exacerbation functional state.
Symptoms and Presentation
- Chronic cough
- Shortness of breath/dyspnea on exertion
- Loss of appetite
- Orthopnea
- Fatigue and weakness
- Sputum production
- History of recurrent lower respiratory tract infections with or without exposure to risk factors
- Smoking history: pack-year (number of packs of cigarettes per day times number of years the person smoked)
- Occupational and environmental exposures
- Family history
- Past Medical History – Asthma, allergies, childhood respiratory infections
Physical Findings
- General:
- Significant respiratory distress in acute exacerbations
- Muscle wasting
- Chest:
- Increased Anterior-posterior chest wall diameter (barrel chest)
- Wheezing
- Prolonged expiration
- Pursed-lip breathing
- Skin:
- Central cyanosis when arterial oxygenation is low
- Extremities:
- Digital clubbing
- Lower extremity edema in right heart failure
Differential Diagnosis
- Asthma
- Bronchiectasis
- Chest wall disorders
- Congestive heart failure
- Cystic fibrosis
- Diffuse panbronchiolitis
- Interstitial lung disease
- Lung Cancer
- Medication side effects
- Mesothelioma
- Nontuberculous mycobacteria infection
- Obliterative bronchiolitis
- Pulmonary arterial hypertension
- Tracheal stenosis
- Tuberculosis
- Upper airway obstruction (tracheal tumor)
- Vocal cord dysfunction
