SYSTEM AND METHOD FOR MANAGING FLUID LEVELS IN PATIENTS BASED UPON CREATININE CLEARANCE
First Claim
1. A system for monitoring fluid levels in an individual with respect to a desired threshold and prompting when intervention is required comprising:
- an electronic network;
an electronic database connected to said network, said database being suitable for storing a user input range of desired results for creatinine clearance rate of the individual;
a urimeter connected to the patient via a catheter capable of calculating a volume of urine contained therein and reporting the same electronically to said database over said network;
a biosensor positioned between said urimeter and the patient which is capable of determining a creatinine concentration in urine result for the individual; and
a user interface suitable for receiving a creatinine concentration in plasma assay result obtained based on the blood of the individual;
one or more computer processors connected to said network,wherein said computer processors are responsive to said creatinine concentration in urine, said creatinine concentration in plasma, and said volume of urine to determine a creatinine clearance rate, andwherein said computer processors are responsive to said creatinine clearance rate to determine a fluid bolus infusion for the individual when said creatinine clearance rate is below said desired threshold.

Abstract
A creatinine clearance monitoring and fluid level management system for use in the treatment of patients. The system establishes and adjusts the dosing of intravenous fluids based upon periodic creatinine clearance calculations based upon a system specified frequency. Warning or alert messages or signals are produced if creatinine clearance levels indicate the need for the administration of additional fluids based upon a creatinine clearance result below an established normal threshold. Furthermore, the system generates a warning to trigger a more serious intervention in the event a patient'"'"'s creatinine clearance rate falls below a lower established threshold or the system determines that an inordinate amount of fluids have been administered without the anticipated response. The creatinine clearance monitoring and fluid level management system is particularly useful for patients in a hospital or in-patient environment, and particularly those post-operative patients or those in intensive care.

14. A method for monitoring fluid levels in an individual with respect to a desired threshold and prompting when intervention is required comprising the steps of:
-
establishing a desired lower threshold of a creatinine clearance rate for the individual; receiving a creatinine concentration in plasma assay result for the individual; storing said creatinine concentration in plasma assay result in an electronic database; automatically sensing a creatinine concentration in urine result for the individual using a biosensor in fluid communication with a catheter connected to the patient; storing said creatinine concentration in urine result in said database; determining a urine volume for a specified time internal using a urimeter; storing said urine volume in said database; calculating a creatinine clearance rate for the individual using one or more computer processors and aid creatinine concentration in urine result, said creatinine concentration in plasma result, and said urine volume; comparing said creatinine clearance rate to said desired threshold in response to said calculating, using said one or more computer processors; and determine a fluid bolus infusion for the individual using said one or more computer processors when said creatinine clearance rate is below said desired threshold.
