9.6 Respiratory Conditions (COPD, Pneumonia)

Key Takeaways Explain This Topic AI

COPD patients may have hypoxic respiratory drive; use low-flow oxygen (1-2 L/min) and monitor closely

Pursed-lip breathing helps COPD patients exhale trapped air and reduce air trapping

COPD exacerbation treatment: bronchodilators (albuterol), corticosteroids, antibiotics if infection present

Pneumonia presents with fever, productive cough, crackles, and consolidation on chest X-ray

Encourage fluids in pneumonia to thin secretions; incentive spirometry and position changes prevent complications

Respiratory Conditions

Respiratory conditions significantly impact oxygenation and ventilation. Nurses must understand the pathophysiology of these conditions to provide appropriate care and prevent life-threatening complications.

Chronic Obstructive Pulmonary Disease (COPD)

COPD is a chronic, progressive lung disease characterized by persistent airflow limitation. It includes chronic bronchitis and emphysema.

Pathophysiology

Chronic Bronchitis:

  • Inflammation of bronchial tubes
  • Excessive mucus production
  • "Blue bloater" appearance (cyanosis, edema)

Emphysema:

  • Destruction of alveolar walls
  • Loss of elastic recoil
  • Air trapping
  • "Pink puffer" appearance (pursed-lip breathing, barrel chest)
  • Risk Factors
  • Smoking (primary cause - 85-90% of cases)
  • Alpha-1 antitrypsin deficiency
  • Occupational dust and chemical exposure
  • Air pollution
  • Recurrent respiratory infections
  • Clinical Manifestations
  • Finding Description
  • Dyspnea Progressive shortness of breath, especially with exertion
  • Chronic Cough Productive, especially in chronic bronchitis
  • Barrel Chest Increased AP diameter from air trapping
  • Prolonged Expiration Difficulty exhaling due to airway obstruction
  • Use of Accessory Muscles Neck and shoulder muscles during breathing
  • Pursed-Lip Breathing Compensatory technique to exhale CO2
  • Tripod Position Leaning forward with hands on knees
  • Wheezing High-pitched sounds on expiration
  • Clubbing Chronic hypoxia indicator
  • The Hypoxic Drive Concept

Critical Concept: In advanced COPD, patients may lose their normal respiratory drive (response to high CO2) and instead rely on low oxygen levels to stimulate breathing.

Implications for Oxygen Therapy:

  • Use low-flow oxygen (1-2 L/min via nasal cannula)
  • Target SpO2: 88-92% (not 100%)
  • High-flow oxygen may suppress respiratory drive
  • Monitor closely for hypoventilation and CO2 retention
  • Watch for signs of CO2 narcosis: confusion, lethargy, decreased LOC
  • COPD Medications

Bronchodilators:

  • Type Examples Action
  • Short-acting beta-agonists (SABA) Albuterol Rapid relief, "rescue" inhaler
  • Long-acting beta-agonists (LABA) Salmeterol, formoterol Maintenance, use twice daily
  • Anticholinergics (SAMA/LAMA) Ipratropium, tiotropium Reduce secretions, bronchodilation

Anti-inflammatory:

  • Inhaled corticosteroids (ICS): Fluticasone, budesonide
  • Oral corticosteroids for exacerbations

Combination Inhalers:

  • LABA + ICS
  • LABA + LAMA
  • Nursing Interventions for COPD

Breathing Techniques:

  • Pursed-lip breathing: Inhale through nose, exhale slowly through pursed lips (like blowing out a candle)
  • Prolongs exhalation, prevents airway collapse, helps exhale trapped CO2
  • Diaphragmatic breathing: Focus on belly rising with inspiration

Positioning:

  • High Fowler's or orthopneic position (leaning forward)
  • Reduces work of breathing
  • Allows diaphragm to move freely

Energy Conservation:

  • Rest periods between activities
  • Pace activities throughout the day
  • Use assistive devices as needed

Infection Prevention:

  • Annual influenza vaccine
  • Pneumococcal vaccine
  • Avoid crowds during flu season
  • Hand hygiene
  • COPD Exacerbation

An acute worsening of symptoms, often triggered by infection.

  • Signs of Exacerbation
  • Increased dyspnea
  • Change in sputum (volume, color, thickness)
  • Increased cough
  • Fever
  • Confusion (hypoxia or CO2 retention)
  • Treatment
  • Bronchodilators: Albuterol nebulizer treatments
  • Corticosteroids: Prednisone 40-60 mg daily for 5-7 days
  • Antibiotics: If bacterial infection suspected (purulent sputum)
  • Oxygen: Titrate to maintain SpO2 88-92%
  • BiPAP: For respiratory failure to avoid intubation
  • Pneumonia

Pneumonia is an acute infection of the lung parenchyma causing inflammation and consolidation.

Types of Pneumonia

  • Type Description
  • Community-Acquired (CAP) Acquired outside healthcare settings
  • Hospital-Acquired (HAP) Develops > 48 hours after admission
  • Ventilator-Associated (VAP) Develops > 48 hours after intubation
  • Aspiration Inhalation of oral/gastric contents
  • Common Pathogens
  • Setting Organisms
  • CAP Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma
  • HAP/VAP Pseudomonas, MRSA, Gram-negative bacteria
  • Aspiration Mixed anaerobes, Gram-negative
  • Immunocompromised Pneumocystis jiroveci, fungal organisms
  • Clinical Manifestations

Typical Pneumonia:

  • Fever, chills
  • Productive cough (purulent, rust-colored, or green sputum)
  • Pleuritic chest pain (sharp, worse with inspiration)
  • Tachypnea, tachycardia
  • Crackles on auscultation
  • Diminished breath sounds over affected area
  • Dullness to percussion (consolidation)

Atypical Pneumonia:

  • Gradual onset
  • Dry, nonproductive cough
  • Lower fever
  • Headache, myalgias
  • Often caused by Mycoplasma, Chlamydia, or Legionella
  • Diagnostic Tests
  • Test Purpose
  • Chest X-ray Confirms infiltrate/consolidation
  • Sputum Culture Identifies organism (obtain before antibiotics if possible)
  • Blood Cultures For bacteremia detection
  • CBC Elevated WBC indicates infection
  • Procalcitonin Elevated in bacterial pneumonia
  • Pulse Oximetry/ABG Assess oxygenation
  • Treatment of Pneumonia

Antibiotics:

  • Empiric therapy started based on likely pathogens
  • Adjust based on culture results
  • CAP: Macrolide (azithromycin) or respiratory fluoroquinolone
  • HAP/VAP: Broader coverage including anti-pseudomonal agents

Supportive Care:

  • Oxygen therapy to maintain SpO2 > 92%
  • IV fluids if dehydrated
  • Antipyretics for fever
  • Adequate rest
  • Nursing Interventions for Pneumonia

Airway Clearance:

  • Encourage fluids (2-3 L/day if not contraindicated) to thin secretions
  • Humidified oxygen
  • Chest physiotherapy if ordered
  • Incentive spirometry every 1-2 hours while awake
  • Splint chest when coughing

Positioning:

  • Semi-Fowler's or high Fowler's position
  • Turn every 2 hours
  • "Good lung down" for unilateral pneumonia (promotes V/Q matching)

Prevention of Complications:

  • Early mobilization
  • DVT prophylaxis
  • Hand hygiene and isolation if indicated
  • Monitor for sepsis development
  • Comparison: COPD vs. Pneumonia
  • Feature COPD Pneumonia
  • Type Chronic condition Acute infection
  • Onset Progressive Acute
  • Fever Usually absent unless exacerbation Usually present
  • Cough Chronic Acute, productive
  • Lung Sounds Wheezes, diminished Crackles, bronchial sounds
  • Chest X-ray Hyperinflation Infiltrate/consolidation
  • O2 Therapy Low flow (1-2 L/min) As needed for SpO2 > 92%
  • Key Points for the NCLEX
  • COPD: Low-flow oxygen (1-2 L/min), target SpO2 88-92%
  • Pursed-lip breathing helps exhale trapped CO2 in COPD
  • Pneumonia: Encourage fluids to thin secretions
  • Incentive spirometry prevents atelectasis and complications
  • Crackles = pneumonia (fluid in alveoli)
  • Wheezes = COPD/asthma (airway narrowing)
  • Obtain sputum culture before antibiotics when possible
  • " Good lung down " positioning for unilateral pneumonia
