CO2 Retention Risk in COPD (High-Flow O2)
Estimates risk of hypercapnic respiratory failure when administering supplemental oxygen in COPD patients. Guides target SpO2 selection (88-92%).
Score interpretation
Low CO2 retention risk
→ Target SpO2 94-98%; standard oxygen titration
Moderate CO2 retention risk
→ Target SpO2 88-92%; obtain ABG; consider controlled oxygen
High CO2 retention risk
→ Target SpO2 88-92%; urgent ABG; early NIV consideration; avoid uncontrolled O2
Interpretation bands for the CO2 Retention Risk. Apply clinical judgement and local guidance.
