A peristaltic infusion pump with improved low flow performance. The pump includes a cam shaft having cams offset in an axial direction, pump fingers that engage a tube, each finger coupled to a respective cam, the fingers creating a pumping region and an occlusion region within the tube, a motor coupled to the cam shaft, a memory, and a controller. The controller implements cam rotation instructions received from the memory to cause the pump to position the fingers in the occlusion region prior to beginning an infusion therapy to deliver fluid to patient through the tube at a patient fluid delivery rate, rotate the cam shaft to transition the fingers from the occlusion region to the pumping region at a startup rate that is faster than a patient fluid delivery rate, and rotate the cam shaft at the patient fluid delivery rate in the pumping region.
