Abstract

Techniques for initiating direct communication between an emergency medical device, such as an automated external defibrillator (AED) and a safety agency may include detecting an event and contacting the safety agency in response to the detected event and user authorization. For example, the AED may detect an event such as removal of the AED from a mount and alert an operator of the intent to send contact the safety agency. The AED determines whether an override command was received from the operator in a defined amount of time. When the operator does not input an override command, the AED interprets the absence of the override command as user authorization and contacts the safety agency via a communication unit. For instance, the AED may generate an advisory and send the advisory to the safety agency. The initiation of direct communication between the AED and the safety agency by the AED enables the operator to interact with a patient, e.g., perform CPR on the patient.

7. The method of claim 6, in which the input medium is one of a button, a switch, and a dial.

8. The method of claim 1, in which the emergency medical device includes an automated external defibrillator (AED).

9. The method of claim 8, in which detecting an event includes detecting coupling of electrodes to the AED.

10. The method of claim 8, in which detecting an event includes detecting attachment of electrodes to a body of a patient.

11. The method of claim 8, in which detecting an event includes receiving an advisory decision to shock a patient from the AED.

12. The method of claim 8, in which detecting an event includes delivering a shock to the patient with the AED.

13. The method of claim 1, further comprising conveying information to the safety agency.

14. The method of claim 1, in which contacting the safety agency includes opening a voice channel between the device and the safety agency.

15. The method of claim 1, in which contacting the safety agency includes sending an advisory from the device to the safety agency.

16. The method of claim 15, in which the advisory includes a recorded message.

17. The method of claim 15, in which the advisory includes at least one of patient information, therapy information, and location information.

18. The method of claim 1, in which determining that the user authorized contacting the safety agency comprises determining that an override command was not received by the emergency medical device in response to the alerting of the user.

19. The method of claim 1, further comprising:

receiving instructions from a dispatcher of the safety agency; and

conveying the instructions to an operator.

20. The method of claim 18, in which conveying the instructions to the operator includes conveying the instructions to the operator via a speaker.

21. The method of claim 18, in which conveying the instructions to the operator includes conveying the instructions to the operator via a display.

22. The method of claim 1, further comprising contacting the safety agency using one of a mobile phone, a wireless local area network (WLAN) card, a infrared (IR) card, a network card, and a modem.

23. The method of claim 15, wherein sending an advisory comprises sending a prerecorded message stored by the external therapeutic emergency medical device that includes information relating to a location of the external therapeutic emergency medical device.

24. The method of claim 1, wherein determining that the user authorized contacting the safety agency comprises receiving an authorization input from a user in response to the alert.

25. An external therapeutic emergency medical device comprising:

a detector that detects an event and alerts a user of an intent to contact a safety agency in response to the detected event; and

a communication unit that contacts a the safety agency in response to a determination that the user authorized contacting the safety agency in response to the alert.

26. The device of claim 25, in which the communication unit contacts the safety agency by sending an advisory from the device to the safety agency.

27. The device of claim 25, in which the communication unit contacts the safety agency by opening a voice channel between the device and the safety agency.

28. The device of claim 25, in which the event is removal of the device from a mount.

29. The device of claim 25, in which the event is opening of a cover associated with the device.

30. The device of claim 25, in which the event is power-up of the device.

31. The device of claim 25, in which the event is actuation of an input medium on the device.

32. The device of claim 31, in which the input medium is one of a button, a switch, and a dial.

33. The device of claim 25, further comprising an input medium to initiate the detection.

34. The device of claim 33, in which the input medium is one of a button, a switch, and a dial.

35. The device of claim 25, in which the communication unit contacts the safety agency in response to a determination that an override command was not received by the emergency medical device in response to the alerting of the user.

38. The device of claim 25, further comprising a speaker to convey information to an operator.

39. The device of claim 25, further comprising a display to convey information to an operator.

40. The device of claim 25, further comprising a microphone to input information into the device.

41. The device of claim 25, in which the communication unit includes at least one of a mobile phone, a wireless local area network (WLAN) card, a infrared (IR) card, a network card, and a modem.
