Bronchodilator Reversibility



  • Bronchodilator reversibility is indicative of asthma, though some reversibility may be present in COPD.
    • How to Assess

    • Perform spirometry before and after administering a bronchodilator - usually salbutamol.
    • Interpretation

    • Significant reversibility is defined as a 12% or >200mL increase in FEV₁ or FVC after bronchodilator.
