Tag: Spirometry

According to the FDA, improved spirometry after using an inhaler like albuterol indicates bronchial smooth muscle relaxation and improved lung function. This is how **albuterol** effectively increases Forced Expiratory Volume in one second (**FEV1**), offering rapid relief from bronchospasm in conditions such as asthma and COPD.

According to recent guidelines from the American Thoracic Society and European Respiratory Society, a significant bronchodilator response is defined as an increase in forced expiratory volume in 1 second (FEV1) or forced vital capacity (FVC) by at least 10% of the predicted value. This metric is crucial for answering the question: **do bronchodilators improve FEV1**, and if so, to what extent for different respiratory conditions? {Link: Dr.Oracle https://www.droracle.ai/articles/174596/improved-spirometry-with-inhaler-means-what}
