Increased perception of dyspnea by inhalation of short acting beta2 agonist in patients with asthma of varying severity.
Poor perception of dyspnea in asthma may lead to a delay in starting appropriate treatment which is probably one of the factors contributing to death from asthma. ⋯ These studies demonstrate that inhalation of short acting beta2 agonist treatment decrease dyspnea, but increase perception of dyspnea induced by a resistive load in patients with asthma, and the mechanism of the increased perception may not be related to the increased airflow rate. It may be due to some local or central effects of bronchodilator drug on perception of asthma.
