Method and apparatus for displaying physiological patient data
First Claim
Patent Images
1. A method of displaying physiological patient data from a cyclic physiological waveform, the method comprising the steps of:
- acquiring physiological patient data from a cyclic physiological waveform;
storing the physiological patient data in a memory array;
displaying the physiological patient data in a three-dimensional representation by parsing the physiological patient data into a series of waveforms such that each successive waveform is plotted in a temporal alignment to allow detection of long term trends in the physiological patient data;
colorizing the three-dimensional representation by automatically selecting a first data point along a current waveform in the series of waveforms, the selected first data point having a representative X coordinate, Y coordinate and Z coordinate,automatically identifying a first area between the current waveform and a second waveform in the series of waveforms based upon the coordinates of the selected first data point,automatically applying a first predetermined color to the identified first area if the amplitude of the selected first data point is in a first range,automatically applying a second predetermined color to the identified first area if the amplitude of the selected first data point is in a second range, andautomatically applying a third predetermined color to the identified first area if the amplitude of the selected first data point is in a third range.
