Can it calculate fev1 / fvc?

no, the device does not calculate this ratio because it does not measure FVC. It measures and trends Peak Flow (PEF) and the Forced Expired Volume at one second (FEV1)

My unit functions very inconsistently. At times out of 3 readings, I will register a 480, 20, 25. Other times, it will only register two of my three readings. I get too many readings in the 20s, then all of a sudden it will throw in a 520 etc., that I am not sure I can trust it anymore. I am currently shopping for another unit.

Which app can calculate fcv, fef25/75, fev1/fvc? my fev1 is at 40 percent and i have no diagnosis yet.

Hi. MIR Spirobank App can calculate fcv, fef25/75, fev1/fvc and more. But this app is not compatible with MIR Smart One device. The compatible device is MIR Spirobank Smart. You can email us for further info on how to get this device (not available on Amazon for the moment). Please visit spirometry.com and fill in the contact form. Thank you!
