CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD)

Complete Nursing Notes + NORCET MCQ Practice Test

1. Definition

Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory condition characterized by persistent respiratory symptoms and persistent airflow limitation, usually due to abnormalities of the airways and/or alveoli caused by significant exposure to harmful particles or gases.

NORCET Point: COPD is generally characterized by persistent airflow limitation and is commonly associated with smoking and other long-term exposure to harmful inhaled substances.

2. Major Components of COPD

Condition Main Pathological Change Typical Features
Chronic Bronchitis Chronic airway inflammation and mucus hypersecretion Productive cough, sputum, wheezing
Emphysema Destruction of alveolar walls with loss of elastic recoil Dyspnea, hyperinflation, air trapping

Important: COPD is not simply synonymous with either chronic bronchitis or emphysema. Patients may have features of both.

3. Risk Factors

  • Cigarette smoking
  • Passive smoke exposure
  • Occupational exposure to dust, fumes and chemicals
  • Indoor air pollution
  • Outdoor air pollution
  • Recurrent respiratory infections
  • History of childhood respiratory problems
  • Genetic factors
  • Alpha-1 antitrypsin deficiency
  • Increasing age
Most important preventable risk factor: Tobacco smoking.

5. Clinical Manifestations

Respiratory Symptoms

  • Progressive dyspnea
  • Chronic cough
  • Sputum production
  • Wheezing
  • Chest tightness
  • Difficulty clearing secretions
  • Reduced exercise tolerance

Advanced Features

  • Severe fatigue
  • Weight loss
  • Accessory muscle use
  • Prolonged expiration
  • Barrel-shaped chest due to hyperinflation
  • Cyanosis in some patients
  • Peripheral edema in advanced disease with right-sided heart involvement

6. Assessment Findings

Assessment Possible Finding
Respiratory rate May be increased
Breath sounds Reduced air entry, wheezing or prolonged expiration
Chest Hyperinflation/barrel-shaped appearance in advanced disease
Sputum May be increased, particularly during exacerbation
Oxygenation May be reduced in advanced disease or exacerbation
Activity tolerance Reduced

7. Diagnosis & Investigations

1. Spirometry – Key Investigation

Spirometry is used to demonstrate persistent airflow limitation.

Parameter Meaning
FEV₁ Forced expiratory volume in the first second
FVC Forced vital capacity
FEV₁/FVC Ratio used to assess airflow obstruction
A post-bronchodilator FEV₁/FVC ratio below 0.70 is consistent with persistent airflow obstruction in the appropriate clinical context.

Other Investigations

  • Pulse oximetry
  • Arterial blood gas analysis when clinically indicated
  • Chest X-ray
  • CT chest in selected cases
  • Complete blood count when indicated
  • Alpha-1 antitrypsin testing in appropriate patients

8. COPD Exacerbation

An acute exacerbation is a period of worsening respiratory symptoms, particularly increased dyspnea, cough and/or sputum, requiring additional treatment.

Common Triggers

  • Respiratory infections
  • Air pollution
  • Continued smoking
  • Failure to use prescribed treatment
  • Other environmental irritants
Red Flags: Severe breathlessness, altered mental status, marked fatigue, inability to speak normally, worsening hypoxemia, or signs of respiratory failure require urgent clinical assessment.

9. Medical Management

A. Smoking Cessation

  • Ask about tobacco use.
  • Provide counseling and behavioral support.
  • Offer appropriate pharmacological cessation support when indicated.
  • Explain that stopping smoking can slow further loss of lung function.

B. Bronchodilators

Short-acting bronchodilators: Used for rapid symptom relief when prescribed.
LABA: Long-acting beta₂ agonists provide prolonged bronchodilation.
LAMA: Long-acting muscarinic antagonists provide prolonged bronchodilation and are important maintenance medications.
LABA + LAMA: Dual long-acting bronchodilation may be used when symptoms require additional bronchodilator treatment.

C. Inhaled Corticosteroids

ICS may be appropriate for selected patients, particularly when there are specific clinical indications such as frequent exacerbations and features suggesting corticosteroid responsiveness. They are not automatically required for every COPD patient.

D. Oxygen Therapy

Long-term oxygen therapy may be indicated for selected patients with severe chronic hypoxemia after appropriate assessment.

Nursing Alert: In patients at risk of hypercapnic respiratory failure, oxygen should be administered according to the prescribed target and the patient's clinical/ABG status should be monitored.

E. Pulmonary Rehabilitation

  • Exercise training
  • Breathing strategies
  • Education
  • Nutrition support when needed
  • Self-management training

10. Pursed-Lip Breathing

This technique can help reduce dynamic airway collapse and improve control of breathing.

  1. Relax the neck and shoulders.
  2. Inhale slowly through the nose.
  3. Purse the lips as if gently blowing out a candle.
  4. Exhale slowly through pursed lips.
  5. Make expiration longer than inspiration.
Key idea: Slow, prolonged expiration through partially closed lips helps maintain airway pressure during expiration.

11. Diaphragmatic Breathing

  1. Place one hand on the chest and one on the abdomen.
  2. Inhale slowly through the nose.
  3. Allow the abdomen to rise more than the chest.
  4. Exhale slowly.
  5. Practice regularly as instructed.

12. Nursing Management

Assessment

  • Assess respiratory rate, rhythm and effort.
  • Monitor breath sounds.
  • Assess sputum amount, color and consistency.
  • Monitor SpO₂ as prescribed.
  • Assess activity tolerance.
  • Monitor mental status for signs of hypoxemia/hypercapnia.
  • Assess nutritional status and weight.

Positioning

  • Provide a comfortable upright position.
  • High-Fowler's position may improve lung expansion.
  • Encourage a supported forward-leaning position when it helps relieve dyspnea.

Airway Clearance

  • Encourage effective coughing techniques.
  • Maintain adequate hydration when not contraindicated.
  • Administer prescribed inhaled medications.
  • Monitor secretion characteristics.

Oxygen Administration

  • Administer oxygen as prescribed.
  • Monitor response to oxygen therapy.
  • Monitor for worsening CO₂ retention when clinically indicated.
  • Review ABG results when available.

Medication Responsibilities

  • Check medication and inhaler technique.
  • Monitor therapeutic response.
  • Observe for adverse effects.
  • Teach correct inhaler use.
  • Reinforce adherence to prescribed maintenance therapy.

13. Inhaler Technique – Patient Education

  1. Shake the inhaler if required.
  2. Remove the cap.
  3. Exhale gently before inhalation.
  4. Seal lips around the mouthpiece.
  5. Coordinate actuation with slow inhalation for a metered-dose inhaler.
  6. Hold the breath briefly if able.
  7. Exhale slowly.
  8. Use a spacer when prescribed/recommended.
  9. Rinse the mouth after inhaled corticosteroids.
Common exam point: Poor inhaler technique can result in inadequate drug delivery despite a correctly prescribed medication.

14. Nutrition in COPD

  • Provide small, frequent meals when large meals worsen breathlessness.
  • Encourage adequate nutritional intake.
  • Monitor weight and muscle mass.
  • Allow rest before meals if fatigue is significant.
  • Encourage appropriate fluid intake unless contraindicated.
Practical point: Severe hyperinflation and dyspnea can make eating tiring, so meal planning and energy conservation are important.

15. Energy Conservation

  • Plan activities in advance.
  • Alternate activity with rest periods.
  • Sit while performing activities when possible.
  • Keep frequently used items within easy reach.
  • Avoid unnecessary rushing.
  • Use prescribed breathing techniques during exertion.

16. Complications of COPD

  • Acute exacerbations
  • Respiratory failure
  • Pulmonary hypertension
  • Cor pulmonale
  • Recurrent respiratory infections
  • Secondary polycythemia associated with chronic hypoxemia
  • Pneumothorax in selected patients
  • Reduced exercise tolerance
  • Weight loss and muscle wasting

17. Cor Pulmonale

Cor pulmonale refers to structural and functional changes of the right ventricle resulting from pulmonary hypertension associated with diseases of the lungs or pulmonary vasculature.

Possible Findings

  • Peripheral edema
  • Raised jugular venous pressure
  • Right-sided heart failure features
  • Fatigue
  • Worsening exercise intolerance

18. COPD vs Bronchial Asthma

Feature COPD Asthma
Typical onset Usually adulthood Often earlier in life, but can occur at any age
Airflow limitation Persistent Variable; often substantially reversible
Smoking association Strong Not the defining cause
Symptoms Usually progressive Often variable/episodic
Common trigger pattern Infections, smoke, pollutants and other irritants Allergens, exercise, infections and other triggers

19. Patient Education

  • Stop smoking and avoid secondhand smoke.
  • Use inhalers exactly as prescribed.
  • Learn and demonstrate correct inhaler technique.
  • Recognize early worsening of symptoms.
  • Follow the prescribed COPD action plan.
  • Maintain recommended physical activity/pulmonary rehabilitation.
  • Maintain adequate nutrition.
  • Practice breathing techniques.
  • Attend scheduled follow-up.
  • Follow recommended vaccination advice.

20. NORCET High-Yield Points

  • COPD → persistent airflow limitation.
  • Major preventable risk factor → cigarette smoking.
  • Key diagnostic test → spirometry.
  • FEV₁/FVC < 0.70 after bronchodilator → persistent airflow obstruction in appropriate clinical context.
  • Emphysema → alveolar wall destruction + loss of elastic recoil.
  • Chronic bronchitis → chronic productive cough.
  • Pursed-lip breathing → prolonged expiration and reduced airway collapse.
  • Barrel chest → hyperinflation.
  • Peripheral edema + raised JVP → consider cor pulmonale.
  • Long-term oxygen therapy → selected patients with severe chronic hypoxemia.
  • LABA/LAMA → long-acting bronchodilation.
  • ICS → selected COPD patients, not automatically every patient.
  • Chronic hypoxemia → may cause secondary polycythemia.
