Abstract

Cardiac electrodes and techniques for testing application of the electrodes to a victim are described herein.

Claims

1-28. -28. (canceled)

29. A device comprising:

an electronic interface arranged to;

receive image information from a camera in an electrode, the image information providing information from which information about the position of the electrode relative to an subject'"'"'s chest can be obtained; and

provide feedback to a rescuer about the positioning of the electrode based on the received image information.

30. The device of claim 29, further configured to determine a position of the electrode based on the received image information.

31. The device of claim 29, wherein the electronic interface is configured to provide feedback to the rescuer by sending a signal to an indicator in the electrode to cause the indicator to be illuminated when the electrode is adequately positioned for application to the victim'"'"'s chest.

32. The device of claim 29, wherein the electronic interface is configured to provide feedback to the rescuer by sending signals to one or more indicators in the electrode to cause the indicators to be illuminated to indicate a direction in which the electrode should be moved.

34. The device of claim 31, wherein the one or more indicators comprise:

a first light emitting diode configured to provide information indicating the electrode should be moved toward the subject'"'"'s head;

a second light emitting diode configured to provide information indicating the electrode should be moved toward the subject'"'"'s feet;

a third light emitting diode configured to provide information indicating the electrode should be moved to the left; and

a fourth light emitting diode configured to provide information indicating the electrode should be moved to the right.

35. The device of claim 29, wherein the camera comprises a video camera in the electrode.

36. The device of claim 29, wherein the camera comprises a still image camera in the electrode.

37. The device of claim 29, further comprising a processor configured to determine information about the positioning of the electrode by determining an x-translation and a y-translation from a desired position.

38. The device of claim 29, further comprising a processor configured to determine whether the electrode is adequately positioned for application to the victim'"'"'s chest.

39. The device of claim 29, wherein the image information comprises a still image.

40. The device of claim 39, wherein the image information comprises a video input.

41. The device of claim 39, further comprising a speaker configured to provide the feedback to the rescuer about the positioning of the electrode.

42. The device of claim 39, further comprising a processor configured to:

determine an impedance between a first electrically conductive element and a second electrically conductive element of the electrode; and

compare the impedance to a threshold to determine whether the first electrode is affixed to a subject'"'"'s chest.
