Study Notes
Chronic Obstructive Pulmonary Disease (COPD)
- COPD is an irreversible respiratory disease, a combination of emphysema and chronic bronchitis, causing airflow obstruction and breathing difficulty.
- Distinct from asthma, which is reversible.
Emphysema
- A component of COPD.
- Damages alveoli, reducing lung elasticity.
- Leads to lung hyperinflation and air trapping.
Chronic Bronchitis
- Another component of COPD.
- Involves airway inflammation and mucus hypersecretion.
Pathophysiology of COPD
- Combination of emphysema and bronchitis' effects.
- Emphysema damages alveoli (air sacs), hindering gas exchange and causing hyperinflation.
- Bronchitis leads to airway inflammation and mucus buildup, further obstructing airflow.
- These changes lead to hypoventilation, low blood oxygen (hypoxemia), and carbon dioxide buildup (hypercapnia).
Risk Factors for COPD
- Smoking is the primary risk factor.
- Other risk factors include air pollution, occupational chemical/dust exposure, and infection.
Signs and Symptoms of COPD
- Cough, excessive mucus (sputum)
- Shortness of breath (dyspnea)
- Crackles/wheezing while breathing
- Barrel chest
- Use of accessory muscles for breathing
- Clubbing of fingers (enlarged tips, spoon-shaped nails)
- Cyanosis (bluish skin discoloration due to low oxygen)
- Hyperresonance (louder, lower-pitched sound on percussion, due to air trapping)
- Rapid, shallow breathing
- Lower blood oxygen saturation
- Tripod positioning (leaning forward with elbows on knees)
Diagnostic Methods for COPD
- Arterial Blood Gas (ABG): Measures blood oxygen (SpO2) and carbon dioxide (PaCO2)/oxygen (PaO2) levels.
- Normal SpO2 is 95-100%; COPD patients often have lower levels, typically in the low 90s.
- Polycythemia: Increased red blood cell count due to chronic low oxygen.
- Chest X-ray: Visualizes the lungs.
- Pulmonary Function Tests (PFTs): Assess lung capacity and airflow.
Treatment for COPD
- Inhaled bronchodilators (e.g., salmeterol, albuterol)
- Anticholinergics (e.g., ipratropium)
- Corticosteroids (e.g., beclomethasone)
- Mucolytics (e.g., acetylcysteine)
- Oxygen therapy
- Systemic corticosteroids (e.g., prednisone, hydrocortisone) for exacerbations.
Nursing Care for COPD Patients
- Upright positioning for easier breathing.
- Oxygen administration as prescribed.
- Monitoring for complications (e.g., right-sided heart failure).
Patient Education for COPD
- Smoking cessation
- Breathing techniques (abdominal, pursed-lip)
- Effective coughing techniques
- Incentive spirometry
- Diet recommendations (small, frequent meals; high calories/protein; increased fluids)
- Home oxygen safety instructions (preventing fires).
