Abstract

Systems and methods for controlling an alarm state, such as volume, based on the presence or absence of a caregiver in a patient'"'"'s room. More specifically, a local sound producing device provides an audible alarm within a room when a caregiver is in the room, while a remote sound producing device provides an audible alarm external of the room when the caregiver is not in the room. Accordingly, volume levels of the sound producing devices depend on the sensed presence or absence of the caregiver within the room. For example, when the caregiver leaves the room, the local sound producing device is deactivated and/or the remote sound producing device is activated, thereby allowing the patient to enjoy a more relaxed environment within the room, yet still continue to be monitored. Conversely, when the caregiver enters the room, the local sound producing device is activated and/or the remote sound producing device is deactivated, thereby allowing the caregiver to monitor the patient when within the room, yet allow decreased monitoring external of the room.

Claims

1. A system for controlling volume, comprising:

a local sound producing device configured to provide an audible alarm within a room;

a remote sound producing device configured to provide an audible alarm external of the room;

a sensing device configured to detect a presence or absence of a caregiver in the room; and

a volume control system configured to change a volume of the local sound producing device and/or remote sound producing device based on the presence or absence of the caregiver in the room.

2. The system of claim 1, wherein the volume control system is configured to decrease the volume of the local sound producing device when the sensing device detects the absence of the caregiver in the room.

3. The system of claim 1, wherein the volume control system is configured to increase the volume of the local sound producing device when the sensing device detects the presence of the caregiver in the room.

4. The system of claim 1, wherein the volume control system is configured to increase the volume of the remote sound producing device when the sensing device detects the absence of the caregiver in the room.

5. The system of claim 1, wherein the volume control system is configured to decrease the volume of the remote sound producing device when the sensing device detects the presence of the caregiver in the room.

6. The system of claim 2, wherein the volume control system decreases the volume of the local sound producing device to a zero level.

7. The system of claim 5, wherein the volume control system decreases the volume of the remote sound producing device to a zero level.

8. The system of claim 1, wherein the local sound producing device is deactivated when the sensing device detects the absence of the caregiver in the room.

9. The system of claim 1, wherein the remote sound producing device is deactivated when the sensing device detects the presence of the caregiver in the room.

10. The system of claim 1, wherein the local sound producing device is activated when the sensing device detects the presence of the caregiver in the room.

11. The system of claim 1, wherein the remote sound producing device is activated when the sensing device detects the absence of the caregiver in the room.

12. The system of claim 1, wherein the local sound producing device contains the volume control system.

13. The system of claim 1, wherein the remote sound producing device contains the volume control system.

14. The system of claim 1, wherein the local sound producing device is configured to be incorporated into a patient monitor in the room.

15. The system of claim 1, wherein the sensing device is a manual device configured to be activated by the caregiver.

16. The system of claim 1, wherein the local sound producing device is configured to be incorporated into a patient monitor in the room and the sensing device is a manual device configured to be activated by the caregiver.

17. The system of claim 16, wherein the patient monitor contains the manual device.

18. The system of claim 1, wherein the sensing device comprises a motion sensing device that is configured to detect the presence or absence of the caregiver in the room.

19. A method for controlling volume, comprising:

providing a local sound producing device configured to provide an audible alarm within a room;

providing a remote sound producing device configured to provide an audible alarm external of the room;

detecting a presence or absence of a caregiver in the room; and

changing a volume of the local sound producing device and/or remote sound producing device based on the presence or absence of the caregiver in the room.

20. The method of claim 19, further comprising:

decreasing the volume of the local sound producing device when the caregiver is not in the room.

21. The method of claim 19, further comprising:

increasing the volume of the local sound producing device when the caregiver is in the room.

22. The method of claim 19, further comprising:

increasing the volume of the remote sound producing device when the caregiver is not in the room.

23. The method of claim 19, further comprising:

decreasing the volume of the remote sound producing device when the caregiver is in the room.

24. The method of claim 20, further comprising:

decreasing the volume of the local sound producing device to a zero level.

25. The method of claim 23, further comprising:

decreasing the volume of the remote sound producing device to a zero level.

26. The method of claim 19, further comprising:

deactivating the local sound producing device when the caregiver is not in the room.

27. The method of claim 19, further comprising:

deactivating the remote sound producing device when caregiver is in the room.

28. The method of claim 19, further comprising:

activating the local sound producing device when the caregiver is in the room.

29. The method of claim 19, further comprising:

activating the remote sound producing device when the caregiver is not in the room.

30. A method for controlling volume, comprising:

detecting a presence or absence of a caregiver in a room; and

changing a volume of a local sound producing device and/or a remote sound producing device based on the presence or absence of the caregiver in the room.

31. The method of claim 30, wherein the local sound producing device is configured to provide an audible alarm within the room.

32. The method of claim 30, wherein the remote sound producing device is configured to provide an audible alarm external of the room.
