Caution on Predictive Values
If you are trying to use this for asthma, and 25-75% (small airway) testing, beware. The note says: "Peak expiratory flow (PEF), 25% flow of the FVC (FEF25), 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."
This is not true, only the first 3 values have predicted outcome percentages. Other than that a nice machine. (Finally I am returning mine, and they are being nice about the return.)
