The amount of inspiratory volume is the amount of air inhaled by the end of calm inhalation. Inspiratory volume is the main component of vital capacity. It reflects the elasticity of the lung and the strength of the inspiratory muscle, and needs to be judged comprehensively with other lung function tests. Two days before the examination, all the drugs for bronchodilation should be stopped, such as Shuchuanling, Bangfu, Meipuqing, aminophylline, Shufumei Lehui, Asami, Aichuan, etc., otherwise it will affect test result.
