The Safey App communicates with Safey Peak Flow Meter and Safey Pocket Spirometer via Bluetooth. The app will measure following parameters:

for Peak Flow Meter - PEF & FEV1

for Pocket Spirometer -

Forced Vital Capacity FVC
Full Volume Loop

Volume expired in the first second - FEV0.75, FEV1, FEV3, FEV6

Ratio between volume expired in a certain time period and FVC - FEV/FVC (FER) for 0.75/1/3/6
Peak expiratory flow - PEF
Forced expiratory flow between the first 25% and 75% of the FVC - FEF25-75 (MEF)
Volume inspired in the first second of the test - FIV1
Forced inspiratory volume - FIVC
Peak inspiratory flow- PIF
Forced inspiratory flow in the first 25% and 75% of the FIV - FIF25-75 (MIF25-75)
Ratio between FEV1 and FEV6 - FEV1/FEV6 FEV1/FEV6
Forced expiratory flow at 50% of FVC divided by FVC - FEF50/FVC
Forced inspiratory flow in the first 25% and 75% of the FIV- FIF25-75 (MIF25-75)
Ratio between FEV1 and FEV6 - FEV1/FEV6 FEV1/FEV6
Forced expiratory flow at 50% of FVC divided by FVC - FEF50/FVC
Force inspiratory flow at first second - FIV1/FIVC (FIR)
Forced expiratory time - FET
