How to get the total amount of time it takes to do something. Please read my description.

O2 >5ppm to a window of time; for example: “We saw sustained O2-readings greater than 5ppm at Goose-Creek for 25-minutes before we recovered to <5ppm”.

I need to find a way to put Greater than 5ppm for a number amount of readings for the Time and collect the total amount of time.
