Abstract

In one embodiment, an apparatus for graphical display of medical information is provided. The apparatus comprises a memory configured to store medical information indicative of multiple categories, each category of medical information representing information about plurality of physiological variables, a processing system configured to determine a data value for at least one physiological variable in each of the category of medical information and further configured for generating a color code using the data values and a display system for displaying a color coded image comprising multiple sections, each section displaying color codes associated with a single physiological variable.

Claims

1. An apparatus for graphical display of medical information, the apparatus comprising:

a memory configured to store medical information indicative of multiple categories, each category of medical information representing information about plurality of physiological variables related to patient monitoring;

a processing system configured to determine a data value for at least one physiological variable in each of the category of medical information and further configured for generating a color code using the data values; and

a display system for displaying a color coded image comprising multiple sections, each section displaying color codes associated with one of the physiological variables.

2. The apparatus of claim 1, wherein the color code is generated from a color map, the color map comprising a predetermined sequence of colors selected from visible color spectrum consisting of the colors red, orange, yellow, green, blue, indigo and violet and wherein each color is mapped to a single data value or a range of data values corresponding to a single physiological variable.

3. The apparatus of claim 2, wherein the color code for each physiological variable is generated from different color maps.

4. The apparatus of claim 1, wherein the color code is generated from a color map, the color map comprising a predetermined sequence of shades of a single color and wherein each shade is mapped to a single data value or a range of data values corresponding to a single physiological variable.

5. The apparatus of claim 1, wherein each category of medical information comprises one of fetal vital signs, maternal vital signs, integrated vital signs, medication and physical procedure.

6. The apparatus of claim 5, wherein the fetal vital signs category comprises one of a fetal heart rate (FHR) waveform, fetal heart rate acceleration or deceleration waveform, long term FHR variability waveform, short term FHR variability waveform, uterine activity waveform, fetal movement detection waveform, signal quality detection waveform and coincidence waveform.

7. The apparatus of claim 5, wherein the maternal vital signs category comprises one of a temperature waveform, pulse oximeter oxygen saturation waveform, maternal heart rate waveform, respiration rate waveform, systolic blood pressure waveform and diastolic blood pressure waveform.

8. The apparatus of claim 5, wherein the integrated vital signs category comprises one of an arithmetic integration waveform, logical integration waveform, temporal integration waveform and spatial integration waveform.

9. The apparatus of claim 5, wherein the medication category comprises one of a dose, first point of time indicating a start time for taking medication, second point of time indicating an end time for taking medication and medication name.

10. The apparatus of claim 5, wherein the physical procedure category comprises one of a fetal stimulus by sound waveform, fetal stimulus by vaginal exam waveform, change maternal position side-to-side waveform, change maternal position Trendlenburg waveform and change maternal position knee-chest waveform.

11. A system for simultaneously displaying a plurality of physiological variables indicative of the condition of a patient, the system comprising:

an acquisition system for receiving medical information indicative of multiple categories, each category of medical information comprising signals corresponding to one or more physiological variables related to patient monitoring;

a processing system for generating plurality of data values each of which is indicative of one of the signals, the processing system further configured for converting each of the data values into color codes; and

a display system for separately and simultaneously displaying each of the color coded values in a graphical form in a time correlated relation wherein variations in the data values are emphasized by differences in color or shade.

12. The systems of claim 11, wherein the color codes for the data values corresponding to a single physiological variable are generated from a color map, the color map representing a predetermined sequence of colors selected from visible spectrum consisting of the colors red, orange, yellow, green, blue, indigo and violet.

13. The system of claim 12, wherein the color map employed for color coding the data values of a first physiological variable is different from the color map employed for color coding the data values of a second physiological variable.

14. The system of claim 11, wherein the color codes for the data values corresponding to a single physiological variable are generated from an individual color and wherein the amplitude of the physiological variable determines the shade of color.

15. A method for generating color coded image of medical information, the method comprising:

obtaining one or more data values for a physiological variable representing medical information;

grouping the data values into one or more data ranges, the data range representing a range of data values;

mapping colors to data ranges in a manner that allows the colors to visually indicate the magnitude of the data ranges; and

marking an indicator for each data value on a graph, the indicator marked with the mapped color of the data range that comprises the data value of the physiological variable.

16. The method of claim 15, wherein the indicator comprises one of a bar, line, point or pixel in graphical form filled, bordered or marked with the mapped color that has been mapped to the data range to which the data value of the physiological variable belongs.

17. A computer program product for implementing within a computer system a method for representing patient medical information as a colorgram, the computer program product comprising:

a computer readable medium for providing computer program code means utilized to implement the method, wherein the computer program code means is comprised of executable code for implementing steps for receiving one or more data values for a physiological variable representing medical information, comparing each data value to a color map in which different color shades are designated for numeric values of the physiological variable, determining a color code for each data value and displaying color coded image, the color coded image comprising a sequence of color codes representing various data values of the physiological variable.

18. The computer program product of claim 20, further comprising executable code for displaying changes in amplitude of the data values corresponding to a single physiological variable as varying shades of a single color.
