COPD is the 3rd leading cause of death in the US. Acute exacerbations account for the majority of COPD hospitalizations and are the #1 driver of COPD mortality. Early nursing recognition prevents ICU escalation.
Pathophysiology (Simplified)
- Emphysema: Destruction of alveolar walls → loss of elastic recoil → air trapping; barrel chest; "pink puffer" (dyspneic but compensated)
- Chronic Bronchitis: Chronic productive cough ≥3 months/year for 2 consecutive years; mucus hypersecretion; airway inflammation; "blue bloater" (cyanotic, edematous)
- Most COPD patients have components of BOTH
- Result: obstructive pattern on PFTs; FEV1/FVC <0.70; reduced FEV1
Nursing Assessment
Baseline COPD Assessment
- Respiratory: RR, SpO2 (baseline often 88–92% in severe COPD), work of breathing, accessory muscle use, pursed-lip breathing, tripod position
- Auscultation: Distant/diminished breath sounds; expiratory wheezes; prolonged expiration; coarse crackles
- Barrel chest: Increased AP diameter; hyperinflated lungs on CXR
- Cough: Productive vs non-productive; color, consistency, amount of sputum; change from baseline
- Activity tolerance: How far can patient walk without stopping? Compare to baseline
- Cor pulmonale: Right heart failure from chronic hypoxia; JVD, peripheral edema, hepatomegaly
ABG Interpretation in COPD
| Finding | Interpretation |
|---|
| Chronic: pH 7.35–7.40, PaCO2 50–60, HCO3 28–32 | Compensated respiratory acidosis — normal for this patient's baseline |
| Acute exacerbation: pH <7.35, PaCO2 rising, HCO3 normal or slightly elevated | Acute uncompensated respiratory acidosis — acute on chronic |
| PaO2 55–60 mmHg or SpO2 88–92% | Target range for supplemental O2 in COPD — do NOT over-oxygenate |
Oxygen Therapy Cautions in COPD
Hypoxic drive myth — USE OXYGEN ANYWAY. While COPD patients CAN rely more on hypoxic drive, withholding O2 from a hypoxic COPD patient causes harm. Give O2, but target SpO2 88–92% — not 98–100%.
- Target SpO2: 88–92% for known severe COPD (prevents CO2 retention and Haldane effect)
- Target SpO2: 94–98% for mild/moderate COPD or unknown baseline
- Use low-flow devices to control FiO2 precisely: nasal cannula (0.5–5L/min) or Venturi mask (24–35% FiO2)
- Monitor ABGs or end-tidal CO2 if CO2 retention is suspected
- Titrate O2 to lowest level that maintains target SpO2
- Never abruptly remove O2 from a hypoxic patient out of fear of hypercapnia — hypoxia kills faster
Acute Exacerbation Management
Exacerbation Triggers
- Respiratory infection (bacteria: H. influenzae, S. pneumoniae; viral: rhinovirus, influenza)
- Air pollution/environmental irritants
- Non-adherence to medications
- Pulmonary embolism (always consider in hospitalized COPD)
- Cardiac decompensation
Priority Nursing Interventions
- Position: high Fowler's (60–90°) or tripod; optimizes diaphragmatic excursion
- O2: titrate to SpO2 88–92% (severe COPD) or 94–98% (mild/moderate)
- Short-acting bronchodilators: albuterol nebulization q20 min x3 (or per order)
- Ipratropium (Atrovent) nebulization with albuterol (combo therapy)
- Systemic corticosteroids: prednisone 40 mg PO or methylprednisolone 125 mg IV
- Antibiotics: if purulent sputum or clinical signs of infection (azithromycin, doxycycline, or amoxicillin-clavulanate)
- Non-invasive ventilation (BiPAP/CPAP): if RR >25, pH <7.35, PaCO2 rising → reduces need for intubation
- Intubation: if BiPAP fails or patient cannot protect airway
COPD Medications
| Drug | Class | Key Points |
|---|
| Albuterol (Ventolin, ProAir) | SABA (Short-Acting Beta2 Agonist) | Rescue inhaler; onset 5 min; duration 4–6 hr; tachycardia and hypokalemia side effects |
| Ipratropium (Atrovent) | SAMA (Short-Acting Muscarinic Antagonist) | Reduces secretions; used with albuterol; onset slower; 6–8 hr duration |
| Tiotropium (Spiriva) | LAMA (Long-Acting Muscarinic) | Once daily; maintenance; assess for urinary retention and glaucoma |
| Salmeterol, Formoterol | LABA (Long-Acting Beta2) | Maintenance; NOT for acute rescue; used in combination inhalers |
| Fluticasone, Budesonide | Inhaled Corticosteroid (ICS) | Maintenance; rinse mouth after use (prevents oral candidiasis) |
| Roflumilast (Daliresp) | PDE4 inhibitor | Oral; for severe COPD with chronic bronchitis; GI side effects; weight loss |
Inhaler technique is critical. Up to 70% of COPD patients use their inhaler incorrectly. Teach-back the correct technique every encounter: shake, exhale, inhale slowly, hold 10 seconds.
Patient Teaching
Pursed-Lip Breathing
- Relax shoulders and neck
- Inhale slowly through NOSE for 2 counts
- Pucker lips as if blowing out a candle
- Exhale slowly through PURSED LIPS for 4 counts (twice as long as inhale)
Pursed-lip breathing creates back pressure, preventing airway collapse and helping exhale trapped air.
Key Teaching Topics
- Smoking cessation: MOST important intervention; slows disease progression; refer to cessation program
- Rescue vs maintenance inhaler: Blue (albuterol) = rescue; other colors = maintenance; use rescue for symptoms, maintenance daily
- Flu & pneumonia vaccines: Annual influenza; pneumococcal (PCV15/PCV20 and PPSV23) — prevent exacerbation triggers
- Energy conservation: Sit to do tasks; prioritize activities; plan rest periods
- Action plan: When to use rescue inhaler, when to call MD, when to go to ED (clear written plan)
- Pulmonary rehab: Supervised exercise + education; proven to improve quality of life and reduce hospitalizations
NCLEX High-Yield Points
- Target SpO2 in severe COPD: 88–92% (not 98–100%)
- Position for dyspnea: high Fowler's (60–90°) or tripod
- Pursed-lip breathing: inhale through nose 2 counts, exhale through pursed lips 4 counts
- Albuterol = rescue; DO NOT use as maintenance; tachycardia and hypokalemia are side effects
- Inhaled corticosteroid: rinse mouth after to prevent oral candidiasis
- COPD chronic ABG: high PaCO2, high HCO3, near-normal pH = compensated respiratory acidosis
- BiPAP is first-line for acute COPD exacerbation before considering intubation
