COPD Exacerbation Management (GOLD 2025)

Algorithm Steps

1. ▶

   Start

   COPD Exacerbation Suspected

   Acute worsening of respiratory symptoms beyond normal day-to-day variation

   1. ◆

      Decision

      Assess Exacerbation Severity

      Evaluate symptoms, signs, and need for hospitalization

      • Mild: Increased SOB, treated with SABDs only
      • Moderate: Requires systemic steroids ± antibiotics
      • Severe: Requires hospitalization or ED visit
      • Assess: dyspnea at rest, RR, HR, SpO2, mental status
      1. ◆

         Decision

         Hospitalization Indicated?

         Assess need for admission

         • Severe symptoms (dyspnea at rest, high RR, SpO2 <90%)
         • Acute respiratory failure
         • New physical signs (cyanosis, edema)
         • Failure to respond to initial treatment
         • Serious comorbidities (HF, arrhythmias)
         • Insufficient home support
         1. ●

            Action

            Outpatient Management

            For mild-moderate exacerbations

            • Increase SABD: Salbutamol 2.5-5mg nebulized PRN
            • Oral corticosteroids: Prednisone 40mg daily x 5 days
            • Antibiotics if purulent sputum: Amoxicillin, Doxycycline, or Azithromycin
            • Review inhaler technique
            • Follow-up in 48-72 hours
            1. ✓

               Outcome

               Discharge Planning

               Criteria and follow-up

               • Stable on usual medications for 12-24h
               • Using inhalers correctly
               • Ensure adequate home support
               • Follow-up within 4-6 weeks
               • Smoking cessation counseling
               • Pulmonary rehabilitation referral
         2. ●

            Action

            ED/Hospital Initial Treatment

            For moderate-severe exacerbations

            • Controlled oxygen: Target SpO2 88-92%
            • Bronchodilators: Salbutamol 2.5-5mg + Ipratropium 500mcg nebulized
            • Systemic corticosteroids: Prednisone 40mg PO or equivalent IV
            • Antibiotics if indicated (increased dyspnea + sputum purulence/volume)
            • Consider prophylactic LMWH
            1. ◆

               Decision

               ABG Assessment

               Check arterial blood gas for respiratory failure

               • pH <7.35 with PaCO2 >45 mmHg = Respiratory acidosis
               • pH <7.25 = Severe acidosis - consider ICU
               • PaO2 <60 mmHg on supplemental O2 = Severe hypoxemia
               1. ◆

                  Decision

                  NIV Indicated?

                  Non-invasive ventilation criteria

                  • Respiratory acidosis (pH <7.35, PaCO2 >45)
                  • Severe dyspnea with accessory muscle use
                  • Persistent hypoxemia despite O2
                  • Contraindications: Cardiac/respiratory arrest, uncooperative, facial trauma
                  1. ●

                     Action

                     Start NIV (BiPAP)

                     Non-invasive ventilation settings

                     • Initial settings: IPAP 10-12, EPAP 4-5 cmH2O
                     • Titrate IPAP for ventilation (↓PaCO2)
                     • Titrate EPAP for oxygenation (↑SpO2)
                     • Target: pH >7.35, SpO2 88-92%
                     • Reassess in 1-2 hours
                     1. ◆

                        Decision

                        NIV Response at 1-2h?

                        Assess response to NIV

                        • Good: pH improving, RR decreasing, patient comfortable
                        • Poor: No improvement or deterioration in pH, RR, mental status
                        1. ⚠

                           Warning

                           ⚠️ Intubation/ICU

                           NIV failure or contraindicated

                           • NIV failure (no improvement in 1-2h)
                           • Decreasing consciousness
                           • Hemodynamic instability
                           • Unable to protect airway
                           • Respiratory arrest
                        2. ●

                           Action

                           Continue NIV

                           Wean as tolerated

                           • Continue until pH normalized
                           • Wean IPAP gradually
                           • Transition to nocturnal NIV if needed
                           • Assess for long-term home NIV
                  2. ●

                     Action

                     Medical Therapy (No NIV)

                     Continue treatment, close monitoring

                     • Continue bronchodilators q4-6h
                     • Corticosteroids: Complete 5-day course
                     • Antibiotics: 5-7 days if indicated
                     • Monitor SpO2, clinical status
                     • Daily ABG if initially abnormal
