Abstract
Fluid introduction into the patient during surgery can be tracked more accurately. For example, saline is often introduced to a patient to clean an operating site. The saline is taken from a sterile bucket and introduced to the patient. In one described approach, the system senses the volume or weight of fluid in the sterile bucket and determines any decrease in the volume or weight to be an introduction of fluid to the patient. If, however, additional saline is added to the bucket, that addition is not counted in the fluid tracking and the further decrements from that new fluid amount is what is used to track fluid addition to the patient.
