1. A system, comprising:
at least one data processor; and
at least one memory storing instructions, which when executed by the at least one data processor, result in operations comprising:
receiving, from a fluid level sensor, one or more first outputs indicative of a fluid level in a drip chamber, the fluid level sensor coupled with a pump, the pump configured to move a fluid from a reservoir containing the fluid to the drip chamber, the fluid being moved through a tube upstream from the pump;
receiving one or more second outputs from a drop sensor coupled with the pump and/or a pressure sensor coupled with the pump, wherein the one or more second outputs from the drop sensor indicate a drip rate for the fluid and the one or more second outputs from the pressure sensor indicate existence of a vacuum in the tube;
detecting, based at least on the one or more first outputs and the one or more second outputs, an abnormal upstream flow condition in the pump, the abnormal upstream flow condition including a full upstream occlusion in the tube, a partial upstream occlusion in the tube, an empty reservoir, and/or a backflow of the fluid into the drip chamber; and
adjusting, based on the detection of the abnormal upstream flow condition in the pump, operation of the pump.
