Abstract
Abstract A method for integrating and displaying medical data in which a computer program links a flow sheet of a medical record to medical charts. The flow sheet has a standardized time scale in the rows and a group of data items in the columns. The program determines the position of a cursor in the flow sheet, and interpolates or erases data in cells of the flowsheet as appropriate. Each empty data cell between cells containing real data is interpolated according to a predetermined formula. The interpolation method can be one in which an average of the preceding cell and the subsequent cell are recalculated up to several hundred times. Another interpolation method involves the use of a gradient, row values and an intercept. The resulting medical charts are designed so that therapeutic data and clinical data are simultaneously displayed on the same chart with the same time scale. The system can be connected to a client server system of a computer network. The system allows the comparison of regularly collected data of many patients because it has a standardized time scale and data interpolated by an appropriate formula.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
146 words
A method of producing medical charts comprising the steps of: monitoring conditions of a patient and taking measurements reflecting those patient conditions; entering datum resulting from said measurements into a buffer in a digital computer; determining the chronological position in a row and column structure where said entered datum should be stored; determining the position of a previously entered piece of datum located in the same column as said entered datum; interpolating data located in the rows between said entered datum and said previously entered piece of datum by summing the data in the row above and below the particular row that is being interpolated, dividing that sum by two, and storing the calculated value in the row that is being interpolated; and displaying on said digital computer's output a medical record containing said entered datum, said previously entered piece of datum, and said interpolated data.
