Abstract

A physiological status monitor has a monitor and an interconnected sensor that generates a sensor signal. The monitor computes physiological parameters responsive to the sensor signal and displays physiological parameters accordingly. In an embodiment, the monitor displays physiological parameter information across multiple patients in a cumulative pie chart format so that a caregiver can quickly discern and readily identify patients in need of immediate medical attention.

Claims

1. A patient monitoring method comprising:

displaying historical physical information on a plurality of patients side by side;

visually comparing the information; and

identifying patients in need of immediate medical attention.

2. The patient monitoring method according to claim 1 wherein the displaying comprises:

dividing the information into a plurality of medical conditions including a normal condition and a serious condition; and

distinguishing the conditions with a plurality of indicators.

3. The patient monitoring method according to claim 2 wherein the comparing comprising:

viewing the indicators; and

discerning a serious condition according to an indicator representing a particular serious condition.

4. The patient monitoring method according to claim 3 wherein the identifying comprising determining a patient having the most percentage of the serious condition indicator as the one in need of immediate medical attention.

5. The patient monitoring method according to claim 4 wherein the physical information is oxygen saturation status.

6. The patient monitoring method according to claim 5 wherein the distinguishing comprises assigning colors to the conditions.

7. The patient monitoring method according to claim 5 wherein the distinguishing comprises assigning objects to the conditions.

8. A physiological status monitor responsive to an interconnected sensor, the sensor generates a sensor signal responsive to a physiological phenomenon and a display presents a measured physiological parameter responsive to the phenomenon, the physiological status monitor comprising:

a monitor that determines a physiological parameter in response to a sensor signal derived from a patient;

a display incorporated with the monitor so as to present the physiological parameter;

a plurality of objects representing historical information regarding the physiological parameter over a plurality of patients; and

a preferred screen presenting the objects side by side on the display for viewing by a caregiver so that the caregiver can visually discern and readily identify patients in need of immediate medical attention.

9. The physiological status monitor according to claim 8 wherein the objects are a plurality of colored pie charts.

10. The physiological status monitor according to claim 9 wherein each of the pie chart comprising:

a plurality of zones representing different medical conditions,

wherein the zones are assigned colors to make a visual distinction.

11. The physiological status monitor according to claim 10 wherein the physiological parameter is oxygen saturation.

12. The physiological status monitor according to claim 11 wherein the colors comprise:

a green color indicating a normal condition;

an orange color indicating an abnormal condition; and

a red color indicating a serious condition,

wherein a patient corresponding to one of the pie charts having the most percentage of the red color is in need of a immediate medical attention.

13. The physiological status monitor according to claim 8:

wherein the objects are a plurality of different shapes,

wherein the shapes are filled in lines, dots, circle and square patterns to make a distinction for a color blind user.
