1) Test items - FVC, FEV1, FEV1% FVC, PEF, FEF25, FEF50, FEF75, MMEF and so
on were used as the measured indexes of FVC.
2) Measured curve graph-flow rate - volume F(L/s)-V(L) graph and volume - time
V(L)-T(s) graph show each measured data of the patient in different colors , and show
Waveform or arc, the operator can selectively view or compare the actual
measurement records to determine the flow rate-The black waveform on the volume
F(L/s)-V(L) graph is used as the predicted value of the tested patient, and the
predicted value is compared with the actual measurement record.
