1. A patient monitor comprising:
- a display device; and
a processor configured to acquire a physiological parameter of a patient and to direct the display device to display a value of the physiological parameter,wherein the displayed value comprises text having a circumscribing outline and a fill populating the outline, andwherein the processor is further configured to direct the display device to smoothly shrink a level of the fill populating the outline over time to indicate a continuum of decreasing intermediate levels of reliability for the physiological parameter, such that the circumscribing outline of the displayed text value has a first level of fill at a first time and the circumscribing outline of the displayed text value has a second, lower level of fill at a second time,wherein the levels of reliability indicate at least in part an elapsed time since the physiological parameter was acquired.

Abstract
A patient monitor configured to display patient information in a display area. The patient information is indicative of at least one physiological parameter of a patient and includes at least one unitary display element in the display area that indicates simultaneously both a quantitative value and a reliability indication of the physiological parameter. An appearance of the display element transitions so as to represent a plurality of different reliability levels, including at least a first reliability level, a second reliability level, and at least one intermediary reliability level between the first and second reliability levels.

2. A method for patient monitoring comprising:
-
using a processor to acquire a physiological parameter of a patient; displaying on a display device a value of the physiological parameter, wherein the displayed value comprises text having a circumscribing outline and a fill populating the outline; and smoothly shrinking a level of the fill populating the outline over time to indicate a continuum of decreasing intermediate levels of reliability for the physiological parameter, such that the circumscribing outline of the displayed text value has a first level of fill at a first time and the circumscribing outline of the displayed text value has a second, lower level of fill at a second time, wherein the levels of reliability indicate at least in part an elapsed time since the physiological parameter was acquired. - View Dependent Claims (11, 12, 13)

3. A patient monitor comprising:
-
a display device; and a processor configured to acquire a physiological parameter of a patient and to direct the display device to display a value of the physiological parameter, wherein the displayed value comprises text having a fill of a first fill color, and wherein the processor is further configured to direct the display device to smoothly shrink a level of the fill over time to indicate a continuum of decreasing intermediate levels of reliability for the physiological parameter by replacing the fill with an upper fill portion having a second fill color and with a lower fill portion having the first fill color, such that a circumscribing outline of the displayed text value has a first level of fill with the first fill color at a first time and the circumscribing outline of the displayed text value has a second, lower level of fill with the first fill color at a second time, and wherein the levels of reliability indicate, at least in part, an elapsed time since the physiological parameter was acquired and wherein the reliability level is represented by the relative heights of the upper and lower portions.

4. A method for patient monitoring comprising the steps of:
-
using a processor to acquire a physiological parameter of a patient; displaying on a display device a value of the physiological parameter, wherein the displayed value comprises text having a fill of a first color; and smoothly shrinking a level of the fill over time to indicate a continuum of decreasing intermediate levels of reliability for the physiological parameter, wherein the replacing comprises replacing the fill with an upper fill portion having a second fill color and with a lower fill portion having the first fill color, such that a circumscribing outline of the displayed text value has a first level of fill with the first fill color at a first time and the circumscribing outline of the displayed text value has a second, lower level of fill with the first fill color at a second time, and wherein the levels of reliability indicate, at least in part, an elapsed time since the physiological parameter was acquired and wherein the reliability level is represented by the relative heights of the upper and lower portions.

5. A patient monitor comprising:
-
a display device; and a processor configured to acquire a physiological parameter of a patient and to direct the display device to display a value of the physiological parameter, wherein the displayed value comprises text having a circumscribing outline and a fill populating the outline, and wherein the processor is further configured to direct the display to smoothly shrink a level of the fill populating the outline over time to indicate a continuum of decreasing intermediate levels of reliability for the physiological parameter, such that the circumscribing outline of the displayed text value has a first level of fill at a first time and the circumscribing outline of the displayed text value has a second, lower level of fill at a second time, and wherein the levels of reliability being based, at least in part, on a statistical measure of accuracy of an algorithm used by the processor to determine the value of the physiological parameter. - View Dependent Claims (6, 14)
