Expert Solution
Step 1: Significant change
A significant change in spirometric results from preshift to postshift, or from prebronchodilator to post bronchodilator, typically involves a noticeable alteration in lung function parameters such as forced expiratory volume in one second (FEV1) or forced vital capacity (FVC). Significant changes often indicate a potential impact on respiratory health.
