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.

Claims

1. A patient monitor configured to display patient information in a display area, the patient information indicative of at least one physiological parameter of a patient and including 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 transitioning 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. The patient monitor of claim 1, wherein an appearance of the display element is modified over time in a manner representative of an elapsed time since the physiologic parameter was measured.

3. The patient monitor of claim 1, wherein an appearance of the display element is representative of an accuracy or validity of the physiologic parameter as measured.

4. The patient monitor of claim 1, wherein the display element is an alphanumeric display.

5. The patient monitor of claim 2, wherein the display element is circumscribed by an outline, the appearance of the display element being modified over time by changing a fill populating the outline.

6. The patient monitor of claim 1, wherein the appearance of the display element is modified over time by changing a color of at least a portion of the display element.

7. A method for patient monitoring comprising the steps of:

displaying a unitary display element representative of a physiologic parameter and indicating simultaneously both a quantitative value and a reliability indication of the physiological parameter;

modifying an appearance of the display element, the appearance of the display element transitioning 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.

8. The method of claim 7, wherein the modification is representative of an elapsed time since the physiologic parameter was measured.

9. The method of claim 7, wherein an appearance of the display element is representative of an accuracy or validity of the physiologic parameter as measured.

10. The method of claim 7, wherein the display element is an alphanumeric display.

11. The method of claim 7, wherein the display element is circumscribed by an outline and the appearance of the display element modified over time by changing a fill populating the outline.

12. The method of claim 7, wherein the appearance of the display element is modified over time by changing a color of at least a portion of the display element.

13. A patient monitor configured to display patient information in a display area, the patient information indicative of at least one physiological parameter of a patient and including 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 modified over time in a manner representative of a elapsed time since the physiologic parameter was measured.

14. A method for patient monitoring comprising the steps of:

displaying a unitary display element representative of a physiologic parameter, the display element simultaneously indicating both a quantitative value and a reliability of the physiological parameter;

modifying an appearance of the display element over time, the modification representative of an elapsed time since the physiologic parameter was measured.
