A METHOD AND APPARATUS FOR MEASURING THE FLUID BALANCE OF A PATIENT DURING SURGERY

摘要

The present invention provides a method and apparatus for measuring the fluid balance of a patient during surgery in which the patient is periodically weighed throughout the operation. The weight values processed to remove unwanted fluctuations and transient effects and an indication of the patient's weight. The patient is preferably weighed using load cells (5) placed in or underneath the operating table (2). The data is preferably displayed graphically relative to a reference weight so that the change in the patient's weight during the course of the operation can be seen.
