Spirometry, particularly forced expiratory volume in one second (FEV1), is considered the gold standard for the evaluation of airway obstruction, and the presence of reversible obstruction on spirometry following short-acting bronchodilator administration may be used to assist in the diagnosis of asthma.1.

A positive bronchodilator response was defined as an increase of ≥12% in forced expiratory volume in one second (FEV1) or ≥25% in forced expiratory flow (FEF25–75%). 43 years experience Allergy and Immunology 5 puffs per week: If you are not using albuterol to prevent or relieve exercise-triggered asthma symptoms the maximum is 4 puffs per … Patients were divided into two groups based on whether they had received two or four puffs of albuterol for bronchodilator assessment.
