First Claim
1. A patient monitoring system for visually depicting a status of a clinical condition of a patient comprising:
- one or more processors;
a display device; and
memory storing instructions that, when executed by the one or more processors, cause the patient monitoring system toreceive a plurality of time series, each time series being biologic particle density of a biologic particle type associated with the patient;
generate a plurality of perturbations by identifying changes in the biologic particle density values of the plurality of time series;
determine, for each perturbation, a plurality of properties of the perturbation, wherein the properties include at least one of a slope, a magnitude, a percent change, a change duration, a minimum, a maximum, and a change relative to a normal range for one of the plurality of biologic particle densities;
assign a severity value to each determined property of each perturbation, wherein the severity values correspond to the severity of the determined property with respect to at least one clinical condition, and wherein the severity values form a set of predefined severity values;
generate a plurality of severity profiles over time for each clinical condition, each severity profile being generated by determining the number of the plurality of properties of the perturbations associated with the clinical condition that match each of the predefined severity values;
generate an image for each of the plurality of severity profiles, each image having one or more cells, wherein each cell is assigned a color associated with one of the predefined severity values, and wherein the number of cells of each color corresponds to the determined number of the plurality of properties of the perturbations associated with the clinical condition that match each of the predefined severity values;
display, on the display device, a two-dimensional map having a plurality of locations, each location corresponding to one of the clinical conditions, anddisplay, for each location on the map, a sequence of the generated images for the severity profile associated with the clinical condition corresponding to said location such that the sequence of generated images forms a dynamic image that visually depicts the status of the clinical condition.

Abstract
A system for converting biologic particle density data into a motion image of at least one clinical condition such as sepsis, wherein the system comprises a processor programmed to detect a plurality of perturbations of the biologic particle densities associated with the clinical condition, detect or determine features of the perturbations, and detect or determine patterns of the perturbations. The processor can also be programmed to generate an image of the clinical condition comprised of time image components comprising a two dimensional user-facing map, wherein time extends along an axis away from the user facing map such that the map may be scrolled forward or backward over time to view different two dimensional images of the clinical condition.
