1. An automated external defibrillator (AED) for use during cardiopulmonary resuscitation (CPR), the AED comprising:
a first electrode pad configured to obtain at least a portion of an electrocardiogram (ECG) signal from an individual;
a second electrode pad configured to obtain at least a portion of an electrocardiogram (ECG) signal from the individual, wherein the first electrode pad and/or the second electrode pad includes an electrode pad visual display configured to be visible to a user of the AED while providing CPR to the individual; and
a controller in communication with the first electrode pad and the second electrode pad, the controller configured to:
(i) process an accelerometer signal received from a sensor to determine a depth of one or more chest compressions during CPR, wherein the sensor includes an accelerometer in the first electrode pad and/or in the second electrode pad;
(ii) compare the determined depth of the one or more chest compressions during CPR to a threshold depth;
(iii) determine, based on the comparison, that the determined depth exceeds or falls below the threshold depth; and
(iv) direct the electrode pad visual display to provide a depth indication to the user of the AED that the determined depth of the one or more chest compressions during CPR exceeds or falls below the threshold depth.
