The spirometer is a portable device for testing lung function. It uses the principle of differential pressure measurement to measure over 100 parameters related to FVC, VC, MVV and MV functions. It can be used in many scenarios, such as hospital, clinic, family, MVV and provocation tests before/after taking medications, etc., which can provide the user with the test results of lung function and serve as a basis for diagnosis for medical personnel.
