How to locate significant points in a graph?

Hi

So I've plotted a graph of two variables from a 118000x2 matrix: Frames and Conductivity. I've attached a picture of the graph. I want to write a code to locate the frame numbers at which the conductivity spikes or declines significantly, seen by the peaks and troughs, as well as the maximum/minimum conductivity reached, the stabilising conductivity value after the change and the number of frames taken for the conductivity to stabilise.

Thank you!
