Abstract

A system is presented including at least one sensor and a monitor in operable communication with the at least one sensor. The monitor is configured to display a plurality of graphs each representing a measured physiologic parameter versus time, the plurality of graphs configured to be aligned with respect to each other along a time axis. A marker moves along the time axis of each of the plurality of graphs in response to an input received from an input unit. The plurality of graphs are stacked with respect to each other in a vertical orientation and in a non-overlapping manner.

Claims

1. A system comprising:

at least one sensor; and

a monitor in operable communication with the at least one sensor, the monitor configured to display a plurality of graphs each representing a measured physiologic parameter versus time, the plurality of graphs configured to be aligned with respect to each other along a time axis;

wherein a marker moves along the time axis of each of the plurality of graphs in response to an input received from an input unit such that the marker intersects the plurality of graphs at a common point on the time axis, and physiologic values at the common point in time of each of the plurality of graphs are displayed on the monitor, continuously and in real-time, as the marker moves across the plurality of graphs.

2. The system according to claim 1, wherein the marker is a time scroll bar.

3. The system according to claim 1, wherein a graph of each measured physiologic parameter is indicative of a trend of the measured physiologic parameter over a period of time.

4. The system according to claim 1, wherein the plurality of graphs are stacked with respect to each other in a vertical orientation and in a non-overlapping manner.

5. The system according to claim 4, wherein the marker is a vertical time scroll bar.

6. The system according to claim 1, wherein the marker is moved to a previous measured time period or point in time corresponding to historical medical events of interest for evaluating the measured physiologic parameters during that measured time period or point in time.

7. The system according to claim 1, wherein the monitor includes a storage module for storing values of the measured physiologic parameters.

8. The system according to claim 7, wherein the values are periodically recorded during predefined points of time.

9. The system according to claim 1, wherein, by moving the marker across a graph of the plurality of graphs, a direct relationship is established between all the physiologic parameters at any given point in time.

10. The system according to claim 1, wherein the measured physiologic parameters include at least one of:

oxygen saturation, pulse rate, respiration rate, heart rate, temperature, arterial pressure, blood pressure, and hydration status.

11. A method comprising:

collecting measured physiologic parameters via at least one sensor;

storing the measured physiologic parameters within a storage unit of a monitor in operable communication with the at least one sensor;

generating a plurality of graphs each representing the measured physiologic parameters versus time, the plurality of graphs configured to be aligned with respect to each other along a time axis;

moving a marker along the time axis of each of the plurality of graphs in response to an input;

intersecting, via the marker, the plurality of graphs each representing a measured physiologic parameter versus time at a common point on the time axis; and

displaying physiologic values at the common point in time of each of the plurality of graphs, continuously and in real-time, as the marker moves across the plurality of graphs.

12. The method according to claim 11, further comprising representing each graph of the measured physiologic parameters as a trend of the measured physiologic parameter over a period of time.

13. The method according to claim 11, further comprising stacking the plurality of graphs with respect to each other in a vertical orientation and in a non-overlapping manner.

14. The method according to claim 13, wherein the marker is a vertical time scroll bar.

15. The method according to claim 11, further comprising moving the marker to a previous measured time period or point in time corresponding to historical medical events of interest for evaluating the measured physiologic parameters during that measured time period or point in time.

16. A non-transitory computer-readable storage medium encoded with a program that, when executed by a processor, causes the processor to:

collect measured physiologic parameters via at least one sensor;

store the measured physiologic parameters within a storage unit of a monitor in operable communication with the at least one sensor;

generate a plurality of graphs each representing the measured physiologic parameters versus time, the plurality of graphs configured to be aligned with respect to each other along a time axis;

move a marker along the time axis of each of the plurality of graphs in response to an input;

intersect, via the marker, the plurality of graphs each representing a measured physiologic parameter versus time at a common point on the time axis; and

display physiologic values at the common point in time of each of the plurality of graphs, continuously and in real-time, as the marker moves across the plurality of graphs.

17. The non-transitory computer-readable storage medium of claim 16, wherein the processor is further caused to stack the plurality of graphs with respect to each other in a vertical orientation and in a non-overlapping manner.

18. The non-transitory computer-readable storage medium of claim 16, wherein the processor is further caused to move the marker across one graph of the plurality of graphs to a point in time, such that all the measured physiologic parameters of all of the plurality of graphs displayed on the monitor at that point in time are configured to be simultaneously analyzed.
