Fluid and electrolyte balance monitoring system for surgical and critically ill patients
First Claim
1. A fluid and electrolyte balance monitoring system, comprising:
- input fluid measuring means for measuring a volume of fluid entering a patient;
input fluid analyzing means for determining electrolyte parameters of fluid entering the patient;
output fluid measuring means for measuring a volume of fluid exiting the patient;
output fluid analyzing means for determining electrolyte parameters of fluid exiting the patient; and
fluid volume and electrolyte tracking means for calculating and monitoring a fluid volume status and an electrolyte status of the patient based on information obtained from said input fluid measuring means, said input fluid analyzing means, said output fluid measuring means, and said output fluid analyzing means.

Abstract
A computer based system for tracking a patient'"'"'s fluid volume and electrolyte (cation or anion concentration) balances, during the period extending from before surgical procedures through the recovery process, which will assist the attending physician in maintaining proper balances in the patient. The system contains automatic sensors for measuring the volumes of fluids administered to and recovered from the patient. The system also preferably contains sensors for measuring electrolyte concentrations in these fluids, and, when sensors are not available, assists the attending physician in estimating. The system assists the attending physician in creating baseline values for a patient'"'"'s fluid and electrolyte values, and then accounts for the fluids going into and out of the patient to continuously track current values. Out of bounds conditions for these balances, when detected, will cause the system to issue alarms and make suggestions to the attending physician for remedial action.
