METHODS AND SYSTEMS FOR OPTIMIZING SHOCK DELIVERY TIME USING AN AUTOMATED EXTERNAL DEFIBRILLATOR
A method ( 100 ) for using an automated external defibrillator (AED) ( 310 ), the method comprising: receiving ( 120 ), during an active CPR protocol, a signal indicative of motion or lack of motion of the individual; analyzing ( 130 ), by the controller, the received signal to determine whether the individual is undergoing motion; providing ( 140 ) a direction to begin or continue chest compressions if the controller determines from the received signal that the individual is not undergoing motion; analyzing ( 150 ), by the controller, a received ECG signal to determine whether the individual could benefit from a shock delivered from the AED; interrupting ( 160 ) the active CPR protocol, if the individual is not undergoing motion and if the individual could benefit from a shock delivered from the AED; and delivering ( 170 ) a shock to the individual.
1 . 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:
receiving, during an active CPR protocol, 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;
providing a direction to begin or continue chest compressions if the controller determines from the received signal that the individual is not undergoing motion;
analyzing, by the controller, a received ECG signal to determine whether the individual could benefit from a shock delivered from the AED;
interrupting the active CPR protocol, if the individual is not undergoing motion and if the individual could benefit from a shock delivered from the AED; and
delivering, via the first and/or second electrode pad, a shock to the individual.
2 . The method of claim 1 , further comprising the step of analyzing, following a determination that the individual is undergoing motion, the received signal to determine whether the motion is indicative of one or more chest compressions.
3 . The method of claim 2 , further comprising the step of analyzing, after determining that the motion is indicative of one or more chest compressions, the received signal to determine a quality of the one or more chest compressions.
4 . The method of claim 3 , further comprising the step of providing a direction regarding the determined quality of the one or more chest compressions.
5 . The method of claim 3 , wherein the quality comprises a rate of chest compressions, a depth of chest compressions, a compression recoil parameter, a compression duty cycle, CPR hand-on time, or a combination thereof.
6 . 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 if 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, if the individual is not undergoing motion and if 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.
7 . The automated external defibrillator (AED) of claim 6 , wherein the processor is further configured to analyze, following a determination that the individual is undergoing motion, the received signal to determine whether the motion is indicative of one or more chest compressions.
8 . The automated external defibrillator (AED) of claim 7 , wherein the processor is further configured to analyze, after determining that the motion is indicative of one or more chest compressions, the received signal to determine a quality of the one or more chest compressions.
9 . 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; and
terminating or delaying the scheduled shock if the received signal indicates that the individual is undergoing motion.
10 . The method of claim 9 , further comprising the step of announcing, after scheduling the shock, that the shock is impending.
11 . The method of claim 9 , further comprising the step of providing a direction that a shock is impending if the controller determines that the individual is undergoing motion.
12 . The method of claim 11 , further comprising the step of delivering, via the first and/or second electrode pad, a shock to the individual after providing the direction.
13 . 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, the second electrode pad, and the sensor, the controller configured to: (i) analyze a received ECG signal to determine whether the individual could benefit from a shock delivered from the AED; (ii) schedule a shock upon a determination that the individual could benefit from a shock delivered from the AED; (iii) receive, after scheduling the shock but before delivering the shock, a signal indicative of motion or lack of motion of the individual; (iv) analyze the received signal to determine whether the individual is undergoing motion; and (v) terminate or delay the scheduled shock if the received signal indicates that the individual is undergoing motion.
14 . The automated external defibrillator (AED) of claim 13 , wherein the processor is further configured to announce, after scheduling the shock, that the shock is impending.
15 . The automated external defibrillator (AED) of claim 13 , wherein the processor is further configured to deliver, via the first and/or second electrode pad, a shock to the individual after providing the direction.
