SYSTEMS AND METHODS FOR DETECTING CARDIAC ACTIVITY AND/OR INACTIVITY
First Claim
1. A glove for use by a rescuer when performing Cardio Pulmonary Resuscitation (CPR) compressions on a victim, the glove comprising:
- a plurality of sheaths adapted to receive a plurality of digits of the rescuer'"'"'s hand;
a first electrode positioned adjacent a distal end of a first one of the sheaths, the first electrode adapted to detect a first ECG voltage of the victim when the glove is worn by the rescuer and placed over the victim'"'"'s chest;
a second electrode positioned away from the first electrode, the second electrode adapted to detect a second ECG voltage of the victim when the glove is worn by the rescuer and placed over the victim'"'"'s chest; and
a controller adapted to receive and process the first and second ECG voltages, the controller adapted to output a signal indicative of cardiac activity of the victim'"'"'s heart based on the first and second ECG voltages.

Abstract
A non-invasive sensor unit, such as a glove or pad, is adapted to be placed over the chest of an injured person who may be in need of CPR and/or AED. The sensor unit includes a plurality of electrodes for detecting one or more ECG voltages of the person. A controller processes the ECG voltages and displays them on a display, thereby enabling the user to assess whether CPR and/or AED is needed. The sensor unit is adapted to continue to provide ECG data while the user is applying chest compressions to the person. The sensor unit may include accelerometers for reducing artifacts from the ECG voltages that arise from the movement of the user while applying chest compressions. The electrodes are, in some embodiments, capacitive sensors that enable ECG voltages to be detected without requiring direct contact with the skin of the person.

19. A glove for use by a rescuer when performing Cardio Pulmonary Resuscitation (CPR) compressions on a victim, the glove comprising:
-
at least four electrodes positioned on a ventral face of the glove at locations adapted to face the victim'"'"'s chest when the glove is worn by the rescuer while applying chest compressions to the victim, the at least four electrodes adapted to detect first, second, third, and fourth ECG voltages, respectively, when the glove is worn by the rescuer and placed over the victim'"'"'s chest; an indicator positioned on a dorsal face of the glove; and a controller adapted to determine at least first, second, third and fourth signal-to-noise ratios (SNR) of the first, second, third, and fourth ECG voltages, respectively, and to output a signal indicative of cardiac activity of the victim'"'"'s heart based upon the ECG voltage with the highest SNR. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
