The portable pulmonary function measurement instrument can be used to measure vital capacity (VC), forced vital capacity (FVC), Maximum Ventilation Volume (MVV). Measurement algorithm refers to the ITS, ERS standards of the American Thoracic Society (ATS)

Adopting pressure-flow sensor, sensitive, precise, easy to launder, clean and durable

All parameters can be displayed on the oversized screen(320x240), built-in memory can store maximum 300 cases of patient measurement results

The instrument can calibrate automatically, all English operation, more convenient to operate

110mm thermal printer built-in, can print out a clear clinical report, predicted value, measured value

Measurement of breathing time: VC time 50 seconds, FVC measuring time 25 seconds, MVV time 12 seconds, in favor of the coordination between patients and the device
