1. An infusion system comprising one or more hardware processors configured to:
receive a desired infusion rate (“X”) for an infusion pump;
calculate an expected accumulated infusion volume as a function of time from the desired infusion rate;
activate delivery of an infusion at the desired infusion rate;
determine an actual accumulated infusion volume at a particular time;
generate a catch-up infusion rate using the desired infusion rate and a catch-up rate factor, corresponding to an equation where the catch-up infusion rate=X*A based on a comparison of the actual accumulated infusion volume and the expected accumulated infusion volume; and
change delivery of the infusion at the catch-up infusion rate,
wherein the one or more hardware processors are further configured to receive input of a maximum permissible catch-up rate factor.
