Description
- Measure the relative functions of FVC, VC and MVV, display and analyse thirty-two parameters, and display the optimal value from many measurements. Besides, the testee condition can be shown by the ratio of the measured value and the predicted value.
- Real-time display respiration waveform: flow-volume loop and volume-time curve chart.
- Display test time and environment temperature.
- Trend chart display, which provides the trend of each parameter within a period for the testee.
- Calibration function to ensure the test accuracy.Power and test indicated.
SPM-A is a hand-held equipment for checking lung conditions, adopts the mode of infrared interruption for measuring FVC(Forced Vital Capacity), VC(Vital Capacity), MVV(Maximal Voluntary Ventilation) and relative parameters
