ABSTRACT:
A monitor to provide substantially real-time estimates of fluid absorption rate and tissue loss rate in a patient during a surgical procedure. The monitor estimates fluid source flow rates and waste fluid flow rates based on weight changes per unit time or direct reading fluid flow rate meters. Tissue loss flow rates are estimated based on tissue concentration measurable in waste irrigation fluid using an optical comparator, and are used to correct waste fluid flow rates. Correct waste fluid flow rates are used in turn to obtain estimated fluid absorption rates.
