CHRONIC BRONCHITIS

Complete Nursing Notes + NORCET MCQ Practice Test

1. Definition

Chronic bronchitis is a clinical condition characterized by a productive cough for at least 3 months in each of 2 consecutive years, after excluding other causes of chronic cough.

NORCET High-Yield:
Chronic bronchitis = productive cough + ≥3 months/year + for 2 consecutive years.

Chronic bronchitis is one of the major clinical phenotypes associated with Chronic Obstructive Pulmonary Disease (COPD), although not every person with chronic bronchitis necessarily has persistent airflow obstruction.

2. Types of Bronchitis

Type	Characteristics
Acute Bronchitis	Usually short-term inflammation of the bronchi, commonly associated with viral respiratory infections.
Chronic Bronchitis	Long-standing productive cough meeting the clinical duration criterion. It may occur as part of the COPD spectrum.

Exam Tip: Do not confuse acute bronchitis with the clinical definition of chronic bronchitis.

3. Etiology and Risk Factors

Major Risk Factors

Cigarette smoking
Passive smoking
Long-term exposure to biomass smoke
Occupational dust exposure
Chemical fumes
Air pollution
Repeated airway irritation
Recurrent respiratory infections
Genetic susceptibility

Most important preventable risk factor: Tobacco smoking.

4. Pathophysiology

Chronic exposure to tobacco smoke / irritants
↓
Airway epithelial irritation
↓
Chronic airway inflammation
↓
Mucous gland enlargement + goblet cell hyperplasia
↓
Excess mucus production
↓
Impaired mucociliary clearance
↓
Airway narrowing
↓
Increased airway resistance
↓
Airflow limitation
↓
Ventilation-perfusion abnormality
↓
Hypoxemia ± Hypercapnia

5. Important Pathological Changes

A. Mucous Gland Enlargement

Chronic irritation can cause enlargement of mucus-producing glands, resulting in increased airway secretions.

B. Goblet Cell Hyperplasia

An increased number of goblet cells contributes to excessive mucus production.

C. Impaired Mucociliary Clearance

Smoking and chronic inflammation impair normal ciliary function. As a result, mucus and inhaled particles are cleared less effectively.

D. Airway Inflammation

Persistent inflammatory changes contribute to airway wall thickening, narrowing and airflow limitation.

E. Small Airway Obstruction

Mucus accumulation and inflammatory narrowing can obstruct smaller airways, especially during expiration.

6. Clinical Manifestations

Respiratory Symptoms

Chronic productive cough
Excess sputum production
Dyspnea
Wheezing
Chest discomfort or tightness
Reduced exercise tolerance
Difficulty clearing secretions

During Exacerbation

Increased cough
Increased sputum volume
Change in sputum character
Increased dyspnea
Worsening wheezing
Fatigue
Fever may occur when infection is present

7. Sputum Characteristics

Finding	Possible Significance
Increased sputum	Increased mucus production or exacerbation
Purulent sputum	May occur during an infectious exacerbation
Blood-streaked sputum	Requires assessment, especially if persistent or significant
Difficulty expectorating	May indicate retained secretions

Nursing Alert: New hemoptysis should not automatically be attributed to chronic bronchitis; it requires appropriate clinical evaluation.

8. Assessment Findings

Chronic cough
Productive cough
Wheezing
Rhonchi or coarse breath sounds due to secretions
Prolonged expiration in associated airflow obstruction
Increased respiratory effort during exacerbation
Reduced oxygen saturation in advanced disease or acute deterioration
Possible cyanosis in significant hypoxemia

9. Diagnosis and Investigations

1. History and Physical Examination

The history should include smoking exposure, occupational exposure, duration and characteristics of cough, sputum production, dyspnea, exacerbations and functional limitation.

2. Spirometry

Spirometry is particularly important when COPD or persistent airflow obstruction is suspected.

Parameter	Meaning
FEV₁	Forced expiratory volume in the first second
FVC	Forced vital capacity
FEV₁/FVC	Helps identify airflow obstruction

Important: The clinical definition of chronic bronchitis is based on the chronic productive cough criterion; spirometry is used to assess airflow obstruction and evaluate possible COPD.

3. Other Investigations When Indicated

Pulse oximetry
Arterial blood gas analysis
Chest X-ray
Sputum examination in selected cases
Complete blood count when clinically indicated
CT chest in selected patients

10. Medical Management

A. Smoking Cessation

Assess tobacco use.
Provide behavioral counseling.
Discuss evidence-based smoking cessation treatment.
Help the patient identify triggers.
Encourage avoidance of secondhand smoke.

Smoking cessation is a key intervention for patients who smoke.

B. Bronchodilators

Short-acting bronchodilators: May be prescribed for rapid relief of bronchospasm and symptoms.

LABA: Long-acting beta₂ agonists provide prolonged bronchodilation for maintenance treatment in appropriate COPD patients.

LAMA: Long-acting muscarinic antagonists provide prolonged bronchodilation and are commonly used as maintenance therapy in COPD.

C. Inhaled Corticosteroids

ICS may be prescribed for selected COPD patients according to clinical characteristics and exacerbation risk. They are not automatically indicated for every patient with chronic bronchitis.

D. Antibiotics

Antibiotics are not routinely required for every episode of increased cough or sputum. They may be considered when bacterial infection is clinically suspected and according to the treatment plan.

E. Oxygen Therapy

Oxygen may be prescribed for patients with significant hypoxemia according to clinical assessment and established indications.

In patients at risk of hypercapnic respiratory failure, oxygen should be carefully titrated according to the prescribed target and monitored appropriately.

11. Nursing Management

A. Respiratory Assessment

Monitor respiratory rate and pattern.
Assess depth and effort of breathing.
Monitor breath sounds.
Assess cough effectiveness.
Observe sputum amount, color and consistency.
Monitor SpO₂ as prescribed.
Assess for cyanosis.
Monitor mental status during deterioration.

B. Positioning

Place the patient in an upright position.
High-Fowler's position may improve lung expansion.
Allow a comfortable forward-leaning position if it helps relieve dyspnea.

C. Airway Clearance

Encourage effective coughing.
Teach controlled coughing techniques.
Encourage adequate hydration if not contraindicated.
Administer prescribed inhaled medications.
Monitor retained secretions.

D. Oxygen Administration

Administer oxygen as prescribed.
Monitor oxygen saturation.
Assess respiratory response.
Monitor ABG when clinically indicated.
Report deterioration promptly.

12. Controlled Coughing Technique

Sit upright and relax the shoulders.
Take a slow deep breath through the nose.
Hold the breath briefly if comfortable.
Open the mouth and cough effectively.
Repeat as necessary without causing excessive fatigue.

The goal is to mobilize and remove secretions while minimizing unnecessary fatigue and airway irritation.

13. Pursed-Lip Breathing

Relax the shoulders and neck.
Inhale slowly through the nose.
Purse the lips gently.
Exhale slowly through the partially closed lips.
Make expiration longer than inspiration.

Purpose: Helps slow expiration and may reduce dynamic airway collapse in patients with airflow obstruction.

14. Patient Education

Stop smoking.
Avoid secondhand smoke.
Avoid occupational and environmental respiratory irritants where possible.
Use inhalers correctly.
Follow the prescribed medication schedule.
Maintain recommended physical activity.
Practice breathing techniques.
Maintain adequate nutrition and hydration when appropriate.
Recognize worsening symptoms early.
Attend follow-up appointments.
Follow recommended vaccination advice.

15. Nutrition and Hydration

Provide small, frequent meals if large meals increase breathlessness.
Monitor body weight and nutritional status.
Encourage adequate protein and energy intake according to individual needs.
Maintain appropriate fluid intake unless contraindicated.
Allow adequate rest before meals.

Adequate hydration can help maintain less-viscous respiratory secretions in appropriate patients, making them easier to clear.

16. Complications

Recurrent respiratory infections
Acute exacerbations
Persistent airflow limitation when associated with COPD
Respiratory failure in advanced disease
Pulmonary hypertension
Cor pulmonale
Chronic hypoxemia
Secondary polycythemia associated with chronic hypoxemia
Reduced exercise tolerance
Weight loss and muscle wasting in advanced disease

17. Acute Exacerbation – Nursing Priorities

Assess Airway & Breathing
↓
Monitor Respiratory Rate + SpO₂
↓
Position Upright
↓
Administer Prescribed Bronchodilator / Oxygen
↓
Assess Response
↓
Evaluate for Infection / Respiratory Failure
↓
Escalate Care if Deteriorating

Emergency Warning Signs: Severe breathlessness, inability to speak comfortably, altered mental status, marked exhaustion, worsening hypoxemia or signs of respiratory failure require urgent assessment and escalation.
