Study Tools For Chronic Obstructive Pulmonary Disease (COPD) for Certified Emergency Nursing (CEN)
Outline
Chronic Obstructive Pulmonary Disease (COPD)
Definition/Etiology:
- Preventable, treatable disease characterized by progressive airflow limitation
- Associated with abnormal inflammatory response that is not fully reversible
Pathophysiology:
The two types of COPD are chronic bronchitis and emphysema
- Chronic bronchitis is defined as cough and sputum production for at least 3 months during 2 consecutive years
- Emphysema is characterized by destruction of alveoli
Clinical Presentation:
Chronic Bronchitis | Emphysema |
“Blue bloater” | “Pink puffer” |
Productive cough | Cough uncommon |
Stocky build | Thin |
Onset 40–50 years old | Onset 50–70 years old |
Normal respiratory rate | Tachypnea |
Hypoxemia | PaO2 normal or slightly decreased |
Increased PaO2 | PaCO2 low or normal until end-stage |
Cyanosis | Barrel chest |
Polycythemia | Accessory muscle use |
Cor pulmonale | Tripod position |
Peripheral edema | Pursed-lip breathing |
Risk for pulmonary embolism | Hyperresonance on percussion |
Enlarged heart on X-ray | Lung over inflation on X-ray Low diaphragm on X-ray |
Collaborative Management:
Assessments:
- ABG, CBC (check for polycythemia)
- Chest X-ray
Interventions:
- Supplemental oxygen to SpO2 90–92%
- Nasal cannula or Venturi mask to control oxygen delivery
- Monitor for return to baseline SpO2
- Monitor for decrease in respiratory rate; if so, reduce or discontinue oxygen
- Noninvasive positive pressure ventilation (CPAP, BiPAP)
- Bronchodilators, IV corticosteroids, antibiotics as needed
- Bed rest in High Fowler position or sit on edge of bed with legs dangling
- IV rehydration
- Monitor for arrhythmias
Evaluation | Patient Monitoring | Education:
- Immunizations
- Avoid respiratory infection exposure
- Eat small, frequent meals to allow maximal chest excursion
- Adequate hydration to keep secretions moist
- Smoking cessation
Linchpins: (Key Points)
- Chronic disease, abnormal inflammatory response
- Air trapping
- Treat exacerbations
