Method for use of color and selective highlighting to indicate patient critical events in a centralized patient monitoring system
First Claim
1. A method for displaying patient information in a patient monitoring system so as to clearly identifying an alarm, comprising the steps of:
- displaying patient information received from a plurality of bedside monitors on a video display screen at a central station, said video display screen having a discrete areas, each of said discrete areas corresponding to a single bedside monitor, said patient information being displayed in each area on a background of a first neutral color when the central station has not received an alarm from the corresponding bedside monitor;
when the central station receives an alarm from one of the bedside monitors, highlighting the alarm by changing the background in the area of the video display screen corresponding to the bedside monitor from which the alarm was received from said first neutral color to a second neutral color which is easily distinguishable from said first neutral color and which does not obscure said patient information; and
changing the background in the area of the video display screen corresponding to the bedside monitor from which the alarm was received from said second neutral color to said first neutral color when the alarm is acknowledged by a user, even when the alarm still exists.

Abstract
A centralized patient monitoring system includes a central station which receives patient information from bedside monitors. The patient information is presented on a video display screen and may include patient demographic information, physiological parameters and a waveform. The display screen is divided into sectors, with each sector containing information for one patient. When an alarm condition occurs at one of the bedside monitors, the alarm condition is transmitted to the central station and is displayed in the corresponding sector of the video display screen. In addition, the alarm condition is highlighted by changing the background in the alarming sector from its normal color, typically black, to a neutral color such as blue, which is easily distinguishable from the normal color and which does not obscure the patient information being displayed. The background of the sector is changed back to the normal color when the alarm is acknowledged by a user. The highlighted background is easily visible from a distance and provides a clear indication of unacknowledged alarms without obscuring other patient information.

8. A central station for displaying patient information in a centralized patient monitoring system, comprising:
-
a video display screen; means for receiving patient information in discrete areas on said video display screen, each of said discrete areas corresponding to a single bedside monitor, including means for displaying said patient information in each of said discrete areas on a background of a first neutral color when the central station has not received an alarm from the corresponding bedside monitor; and means for highlighting an alarm received from one of the bedside monitors by changing the background in the area of the video display screen corresponding to the bedside monitor from which the alarm was received from said first neutral color to a second neutral color which is easily distinguishable from said first neutral color and which does not obscure said patient information, said means for highlighting including means for changing the background in the area of the video display screen corresponding to the bedside monitor from which the alarm was received from said second neutral color to said first neutral color when the alarm is acknowledged by a user, even when the alarm still exists. - View Dependent Claims (9, 10, 11)

12. A method for highlighting patient critical events in a centralized patient monitoring system, comprising the steps of:
-
providing a central station having a video display screen, said central station receiving patient information and patient critical events from a plurality of bedside monitors; displaying said patient information and said patient critical events in discrete areas of said video display screen, each of said discrete areas corresponding to one of said bedside monitors, each of said discrete areas having a background of a first color when a patient critical event has not been received from the corresponding bedside monitor and when a patient critical event has been acknowledged by a user; highlighting a patient critical event that has not been acknowledged by a user by changing the background in the area of the video display screen corresponding to the bedside monitor from which the patient critical event was received from said first color to a second color which is easily distinguishable from said first color and which does not obscure said patient information being displayed; and changing the background in the area of the video display screen corresponding to the bedside monitor from which the patient critical event was received from said second color to said first color when the patient critical event is acknowledged by a user, even when the patient critical event still exists. - View Dependent Claims (13, 14)

15. A method for highlighting patient critical events on a video display of patient information, comprising the steps of:
-
displaying patient information and patients critical events in discrete areas of a video display screen, each of said discrete areas corresponding to a single patient, each of said discrete areas having a background of a first color when a patient critical event has not been received; highlighting a patient critical event by changing the background in the area of the video display screen corresponding to the patient for which the patient critical event occurred from said first color to a second color which is easily distinguishable from said first color and which does not obscure said patient information; and changing the background in the area of the video display screen corresponding to the patient for which the patient critical event occurred from said second color to said first color when the patient critical event is acknowledged by a user, even when the patient critical event still exists. - View Dependent Claims (16)

17. A central station for displaying patient information in a centralized patient monitoring system, comprising:
-
a video display monitor including a video display screen; an interface unit for receiving patient information and alarms from a plurality of bedside monitors; and a display controller responsive to the patient information and alarms received by said interface unit for displaying said patient information and alarms in discrete areas on said video display screen, said display controller including means for displaying said patient information in each of said discrete areas on a background of a first neutral color when the central station has not received an alarm from the corresponding bedside monitors, for highlighting an alarm received from one of the bedside monitors by changing the background in the area of the video display screen corresponding to the bedside monitor from which the alarm was received from said first neutral color to a second neutral color which is easily distinguishable from said first neutral color and which does not obscure said patient information, and for changing the background in the area of the video display screen corresponding to the bedside monitor from which the alarm was received from said second neutral color to said first neutral color when the alarm is acknowledged by a user, even when the alarm still exists.
