Abstract

Medical monitoring systems and methods for reducing the frequency of notifications of transient alarms are disclosed. A medical monitoring system can collect a signal representative of the physiological condition of a patient and can determine a physiological parameter using the collected signal. The medical monitoring system can detect an alarm condition for the physiological parameter. The medical monitoring system can then delay notification of the alarm condition until it persists for a predetermined alarm notification delay time.

Claims

1. (canceled)

2. (canceled)

3. A method for reducing the frequency of patient monitoring alarm notifications from one or more physiological monitoring devices, the method comprising:

receiving patient monitoring data, the patient monitoring data comprising information about the occurrence and duration of patient monitoring alarm conditions;

determining, from the patient monitoring data, an effect of an alarm notification delay time on a resulting number of alarm notifications; and

providing a result of the effect of the alarm notification delay time on the resulting number of alarm notifications.

4. The method of claim 3, wherein the alarm conditions are indicative that a physiological parameter satisfied an alarm criterion.

5. The method of claim 3, wherein the alarm notification delay time is a predetermined duration of time during which the alarm conditions persisted before causing the respective alarm notifications.

6. The method of claim 3, further comprising determining, from the patient monitoring data, the resulting number of alarm notifications for each of a plurality of different alarm notification delay times.

7. The method of claim 6, further comprising identifying a change in alarm notification delay time that disproportionately changes the number of alarm notifications.

8. The method of claim 6, further comprising identifying a change in alarm notification delay time that causes a non-linear change in the number of alarm notifications.

9. The method of claim 6, wherein the result is indicative of a change in alarm notification delay time that reduces the number of alarm notifications corresponding to transient or false alarm conditions.

10. The method of claim 6, further comprising determining, from the patient monitoring data, a frequency of alarm notifications for each of the plurality of different alarm notification delay times.

11. The method of claim 10, further comprising identifying a change in alarm notification delay time that disproportionately changes the frequency of alarm notifications.

12. The method of claim 10, wherein the result is indicative of a change in alarm notification delay time that reduces the frequency of alarm notifications corresponding to transient or false alarm conditions.

13. The method of claim 3, wherein the patient monitoring data corresponds to patients in a common care unit.

14. The method of claim 3, further comprising:

obtaining the patient monitoring data based on physiological signals from a plurality of patients; and

determining a physiological parameter of the patients based on the physiological signals,

wherein the physiological parameter comprises blood oxygen saturation or pulse rate.

15. The method of claim 14, further comprising detecting the alarm conditions for the physiological parameter.

16. The method of claim 15, further comprising providing alarm notifications in response to the alarm conditions persisting for the alarm notification delay time.

17. The method of claim 3, further comprising using the result to program the one or more physiological monitoring devices with a selected alarm notification delay time.

18. A system configured to reduce the frequency of patient monitoring alarm notifications from one or more physiological monitoring devices, the system comprising:

a hardware processor configured to

receive patient monitoring data, the patient monitoring data comprising information about the occurrence and duration of patient monitoring alarm conditions;

determine, from the patient monitoring data, an effect of an alarm notification delay time on a resulting number of alarm notifications; and

provide a result of the effect of the alarm notification delay time on the resulting number of alarm notifications.

19. The system of claim 18, wherein the alarm conditions are indicative that a physiological parameter satisfied an alarm criterion.

20. The system of claim 18, wherein the alarm notification delay time is a predetermined duration of time during which the alarm conditions persisted before causing the respective alarm notifications.

21. The system of claim 18, wherein the hardware processor is further configured to determine, from the patient monitoring data, the resulting number of alarm notifications for each of a plurality of different alarm notification delay times.

22. The system of claim 21, wherein the hardware processor is further configured to identify a change in alarm notification delay time that disproportionately changes the number of alarm notifications.

23. The system of claim 21, wherein the hardware processor is further configured to identify a change in alarm notification delay time that causes a non-linear change in the number of alarm notifications.

24. The system of claim 21, wherein the result is indicative of a change in alarm notification delay time that reduces the number of alarm notifications corresponding to transient or false alarm conditions.

25. The system of claim 21, wherein the hardware processor is further configured to determine, from the patient monitoring data, a frequency of alarm notifications for each of a plurality of different alarm notification delay times.

26. The system of claim 25, wherein the hardware processor is further configured to identify a change in alarm notification delay time that disproportionately changes the frequency of alarm notifications.

27. The system of claim 25, wherein the result is indicative of a change in alarm notification delay time that reduces the frequency of alarm notifications corresponding to transient or false alarm conditions.

28. The system of claim 18, wherein the patient monitoring data corresponds to patients in a common care unit.

29. The system of claim 18, further comprising the one or more patient monitoring devices to obtain the patient monitoring data based on physiological signals from a plurality of patients, wherein the one or more patient monitoring devices are configured to determine a physiological parameter of the patients based on the physiological signals, and wherein the physiological parameter comprises blood oxygen saturation or pulse rate.

30. The system of claim 29, wherein the one or more patient monitoring devices are configured to detect the alarm conditions for the physiological parameter.

31. The system of claim 30, wherein the one or more patient monitoring devices are configured to provide alarm notifications in response to the alarm conditions persisting for the alarm notification delay time.

32. The system of claim 18, wherein the hardware processor is further configured to use the result to program the one or more physiological monitoring devices with a selected alarm notification delay time.
