Controlling parameters for KFT.
Endpoint for Ipol.
Endpoint for Upol
Distance from EP where constant dosing
stops and controlling begins.
Maximum dosing rate.
Minimum volume increment
Type of stop criteria.
Titration stops if stop drift is reached.
Stop if there is no dosing during t(delay).
If t(delay) is ”INF”: stop time.
