Claim:
1. A method for determining an efficiency of a pumping mechanism of an infusion pump and dynamically adapting the pumping mechanism based on the efficiency, the method comprising: connecting an external pumping mechanism to a patient at an extracorporeal connection location of the patient; programming the pumping mechanism to deliver a fluid at an infusion rate wherein the pumping mechanism is configured to deliver the fluid along a fluid line from a fluid supply to a patient and communicates with a programming module having a processor and at least one algorithm which inputs one or more system parameters for determining the efficiency of the pumping mechanism; sensing a first pressure at a location of the fluid line upstream of the pumping mechanism and external to the patient using a first pressure sensor positioned upstream of the pumping mechanism and external to the patient; sensing a second pressure at a location of the fluid line downstream of the pumping mechanism and external to the patient using a second pressure sensor positioned downstream of the pumping mechanism and external to the patient; inputting the first pressure, the second pressure, and one or more system parameters into the at least one algorithm; processing the algorithm to determine the efficiency of the pumping mechanism; and dynamically adapting the pumping mechanism based on the efficiency of the pumping mechanism.
