The Spirometer is a portable device for testing pulmonary function, it adopts differential pressure acquisition principle 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 test before / after medication, etc. which can provide the test results of pulmonary function for the users and the basis for the medical staff to make diagnosis.
