Introduction
SPIROMETER is a hand-held equipment for checking lung conditions, adopts the infrared mode for measuring relative items, it is applicable for hospital, clinic, family for routine test.
Function
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.
