Patent ID: 7818184

Claim:
A patient medical parameter data processing system for providing patient medical parameter data for trend indicative display covering a time period comprising user selectable patient parameter acquisition time intervals, comprising: an acquisition processor for receiving data identifying, for a continuing infusion, (a) rate of volume of fluid infusion into a patient, a fluid type identifier and a start time and start date of said continuing infusion, and for a non-continuing infusion, (b) a total volume of fluid infusion, a fluid type identifier and a time and date of said non-continuing infusion; and a data processor for determining, from said received data, a cumulative total volume infusion of a particular fluid into a particular patient for a particular user selectable patient parameter acquisition time interval, wherein said data processor stores said received data comprising a reduced set of fluid parameter data supporting extrapolation and interpolation of intermediate fluid volume data values affecting fluid cumulative volume computation and excluding storage of fluid parameter data irrelevant to fluid cumulative volume computation.
