Inspiratory Inspiratory Volume (IRV)

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.

Inspection process 嘱The subject takes the sitting position, clips the nose clip, contains the mouthpart, and is connected with the pulmonary function meter. After 5 times of calm breathing, the maximum exhalation to the residual gas position (expiratory lung capacity) or the maximum call after the maximum inhalation After the gas, do a deep inhalation to the lung volume (inhaled lung capacity). Not suitable for the crowd Generally no taboos. Adverse reactions and risks No complications or harm.
