Methods and systems for optimizing shock delivery time using an automated external defibrillator

An automated external defibrillator (AED), comprising:

• a first electrode pad;
• a second electrode pad, the first and/or second electrode pad configured to obtain at least a portion of an electrocardiogram (ECG) signal from an individual;
• and
• a controller in communication with the first electrode pad and the second electrode pad, the controller configured to:
• (i) receive, during an active CPR protocol, a signal indicative of motion or lack of motion of the individual;
• (ii) analyze the received signal to determine whether the individual is undergoing motion;
• (iii) provide a direction to begin or continue chest compressions when the controller determines from the received signal that the individual is not undergoing motion;
• (iv) analyze, by the controller, a received ECG signal to determine whether the individual could benefit from a shock delivered from the AED;
• (v) interrupt the active CPR protocol, when the individual is not undergoing motion and when the individual could benefit from a shock delivered from the AED;
• and (vi) deliver, via the first and/or second electrode pad, a shock to the individual, or request a CPR-free heart rhythm analysis.

A method for using an external defibrillator (AED) comprising:

• (i) a first electrode pad and a second electrode pad, the first and/or second electrode pad configured to obtain at least a portion of an electrocardiogram (ECG) signal from an individual;
• and (ii) a controller in communication with the first electrode pad and the second electrode pad, the method comprising:
• analyzing, by the controller, a received ECG signal to determine whether the individual could benefit from a shock delivered from the AED;
• scheduling a shock upon a determination that the individual could benefit from a shock delivered from the AED;
• receiving, after scheduling the shock but before delivering the shock, a signal indicative of motion or lack of motion of the individual;
• analyzing, by the controller, the received signal to determine whether the individual is undergoing motion indicative of chest compressions;
• and
• terminating or delaying the scheduled shock when the received signal indicates that the individual is undergoing motion.

• and

• (i) analyze a received ECG signal to determine whether the individual could benefit from a shock delivered from the AED;
