Parsons et al. 2013, ATS clinical practice guideline on exercise-induced bronchoconstriction

Official American Thoracic Society clinical practice guideline on exercise-induced bronchoconstriction (Am J Respir Crit Care Med). It defines a positive diagnosis as a fall in FEV₁ of at least 10% from baseline after a standardised exercise or surrogate (eucapnic voluntary hyperpnoea) challenge, and recommends an inhaled short-acting β₂-agonist before exercise as first-line treatment, daily inhaled corticosteroids for those who remain symptomatic, and a pre-exercise warm-up as a non-pharmacological measure.
