<p>This invention is a monitor to provide substantially real time estimates of fluid absorption rate and blood 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. Blood loss flow rates are estimated based on hemoglobin concentration in waste irrigation fluid, and are used to correct waste fluid flow rates. Correct waste fluid flow rates are used in turn to obtain estimated fluid absorption rates. Optional verticality compensation means (93) (93') (93'), and anti-rotation devices (91) are included.</p> |
