- Forced Vital Capacity (FVC), Forced Expired Volume in one second (FEV1), the ratio of FEV1 and FVC (FEV1/FVC)
   Peak expiratory flow (PEF), 25% flow of the FVC (FEF25), 50% flow of the FVC (FEF50), 75% flow of the FVC(FEF75)
   and average flow between 25% and 75% of the FVC(FEF2575) can be measured. Besides, the testee condition can be
   shown by the ratio of the measured value and the predicted value
