The deep inspiratory volume is the amount of air inhaled by the end of the breath, that is, the amount of tidal volume plus the inspiratory volume. 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.

Clinical significance

Deep inspiratory volume is the main component of vital capacity and needs to be judged comprehensively with other pulmonary function tests, which is meaningful for the diagnosis of diseases such as chronic obstructive pulmonary disease.

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

The mouth of the subject contains an interface device, which fixes the nose clip and makes a calm breath through the mouth. When the tidal curve is stable, the force is maximally inhaled at the end of the calming end of expiration, and the maximum exhalation is then applied. At the same time, the recorder was recorded in the whole process to record the lung volume map.

Not suitable for the crowd

Unsuitable for the crowd: Check the people who took the bronchodilator before.

Adverse reactions and risks

Generally no complications and harm.
