## Abstract

Methods and systems are provided for guiding a rescuer in treatment of a patient. A method may include initializing one or more cameras on an external electrode assembly including a pair of electrodes. The method may further include capturing image information via the one or more cameras, the image information comprising a series of images acquired by the one or more cameras. The method may further include, based at least in part on the image information, providing feedback, comprising at least one of visual feedback and audio feedback, on at least one output device to guide the rescuer in the treatment of the patient.

## Claims

### Claim 1

A computer implemented method for guiding a rescuer in treatment of a patient, comprising:
initializing one or more cameras disposed on an external electrode assembly, the external electrode assembly comprising a pair of electrodes;
capturing image information via the one or more cameras, the image information comprising a series of images acquired by the one or more cameras; and
based at least in part on the image information, providing feedback, comprising at least one of visual feedback and audio feedback, on at least one output device to guide the rescuer in the treatment of the patient.

### Claim 2 (depends on 1)

The method of claim 1, wherein initializing the one or more cameras comprises a processor or computing device automatically initializing the one or more cameras.

### Claim 3 (depends on 2)

The method of claim 2, comprising the processor or computing device automatically initializing the one or more cameras upon removal of at least one of the pair of electrodes from a package or upon connection of at least one of the pair of electrodes to a defibrillation device.

### Claim 4 (depends on 1)

The method of claim 1, comprising the processor or computing device initializing the one or more cameras upon the rescuer providing input that causes the processor or computing device to initialize the one or more cameras.

### Claim 5 (depends on 1)

The method of claim 1, wherein providing the feedback comprises providing instructions to the rescuer relating to the treatment of the patient.

### Claim 6 (depends on 5)

The method of claim 5, wherein providing the instructions comprises providing positioning instructions.

### Claim 7 (depends on 6)

The method of claim 6, wherein providing the positioning instructions comprises providing positioning instructions relating to electrode positioning.

### Claim 8 (depends on 1)

The method of claim 1, comprising:
a processor or computing device receiving the image information from the one or more cameras; and
the processor or computing device providing the feedback.

### Claim 9 (depends on 8)

The method of claim 8, comprising the processor or computing device receiving the image information from the one or more cameras, wherein a tablet comprises the processor or computing device.

### Claim 10 (depends on 9)

The method of claim 9, wherein providing the feedback comprises providing the visual feedback on a graphical display of the tablet.

### Claim 11 (depends on 10)

The method of claim 10, wherein providing the feedback comprises providing the visual feedback on a display of the defibrillator.

### Claim 12 (depends on 8)

The method of claim 8, comprising the processor or computing device receiving the image information from the one or more cameras, wherein a defibrillator comprises the processor or computing device.

### Claim 13 (depends on 8)

The method of claim 8, comprising providing the feedback on the at least one output device, wherein the at least one output device does not comprise the processor or computing device.

### Claim 14 (depends on 8)

The method of claim 8, comprising the processor or computing device receiving the image information from the one or more cameras via an electronic interface at least in part via a wired connection.

### Claim 15 (depends on 8)

The method of claim 8, comprising the processing or computing device receiving the image information from the one or more cameras via an electronic interface at least in part via a wireless connection.

### Claim 16 (depends on 1)

The method of claim 1, comprising an electronic interface receiving the image information from the one or more cameras.

### Claim 17 (depends on 1)

The method of claim 1, comprising the electronic interface providing the feedback on the at least one output device.

### Claim 18 (depends on 1)

The method of claim 1, comprising capturing the image information via the one or more cameras, wherein particular images in the series of images are acquired by the one or more cameras at a set time interval.

### Claim 19 (depends on 1)

The method of claim 1, comprising capturing the image information via the one or more cameras, wherein the image information comprises video information.

### Claim 20 (depends on 1)

The method of claim 1, comprising capturing the image information via the one or more cameras, wherein the image information comprises images of features of the patient.

### Claim 21 (depends on 1)

The method of claim 1, comprising capturing the image information via the one or more cameras, wherein the image information comprises images of features of the patient, wherein the features of the patient comprise at least one of: nipples, shoulders, a belly button, and a sternum of the patient.

### Claim 22 (depends on 1)

The method of claim 1, comprising comparing the series of images with stored images using a feature extraction algorithm.

### Claim 23 (depends on 22)

The method of claim 22, comprising comparing the series of images with stored images comprising using a feature extraction algorithm, wherein the features comprise one or more features of the patient.

### Claim 24 (depends on 23)

The method of claim 23, comprising comparing the series of images with stored images comprising using a feature extraction algorithm, wherein the features comprise one or more features of the patient comprising at least one of: nipples, shoulders, a belly button, and a sternum of the patient.

### Claim 25 (depends on 1)

The method of claim 1, comprising initializing the one or more cameras disposed on the external electrode assembly, the external electrode assembly comprising a pair of electrodes, wherein the pair of electrodes comprises a pair of defibrillation electrodes, wherein at least one electrode of the pair of defibrillation electrodes comprises a sensor, for use with a defibrillation device, that provides an output from which information can be obtained about depth of compressions to the patient's chest during CPR.
