Abstract

This document describes an automated external defibrillator comprising a control configured to switch between a pediatric operating mode and an adult operating mode, wherein each operating mode comprises a mode-specific energy configuration and a mode-specific user configuration; an indicator configured to provide an indication of the operating mode in use during a resuscitation process; one or more processors configured to switch to the mode-specific energy configuration and the mode-specific user configuration upon a change of operating mode between the pediatric operating mode and the adult operating mode such that the automated external defibrillator delivers a defibrillating shock to a patient based on the mode-specific energy configuration; and an interface of the automated external defibrillator provides resuscitation instructions to a user based on the mode-specific user configuration.

Claims

1. An automated external defibrillator comprising:

one or more capacitors for delivering a defibrillating shock to a patient;

one or more electronic ports configured to receive signals indicative of sensed physiological parameters of the patient, and to communicate the defibrillating shock to the patient based on a signal produced from an analysis of the sensed physiological parameters of the patient;

a control configured to switch between a pediatric operating mode and an adult operating mode, wherein each operating mode comprises a mode-specific energy configuration and a mode-specific user configuration;

an indicator configured to provide an indication of the operating mode in use during a resuscitation process;

one or more processors configured to switch to the mode-specific energy configuration and the mode-specific user configuration upon a change of operating mode between the pediatric operating mode and the adult operating mode such that the automated external defibrillator delivers a the defibrillating shock to a patient based on the mode-specific energy configuration; and

a user interface that is configured to provide a first type of resuscitation instructions when the mode-specific user configuration is in the pediatric operating mode and a second type of resuscitation instructions when the mode-specific user configuration is in the adult operating mode, the first type of resuscitation instructions being different from the second type of resuscitation instructions.

2. The automated external defibrillator of claim 1 wherein the control is further configured to switch by toggling the operating mode of the automated external defibrillator back and forth between the pediatric operating mode and the adult operating mode after treatment is initiated.

3. The automated external defibrillator of claim 1 wherein the control is further configured to switch the operating mode when the one or more computer processors determine that an electrode assembly in communication with at least one of the electronic ports is usable in both the pediatric operating mode and the adult operating mode.

4. The automated external defibrillator of claim 1 wherein the one or more computer processors are configured to determine when an electrode assembly is configured only for the pediatric operating mode, and, in response, the indicator automatically indicates the pediatric operating mode, and the control is disabled.

5. The automated external defibrillator of claim 1 wherein the one or more computer processors are configured to determine when an electrode assembly is configured only for the adult operating mode, and, in response, the indicator automatically indicates the adult operating mode, and the control is disabled.

6. The automated external defibrillator of claim 1 wherein the user interface includes a visual display configured to provide the at least one of instructions specific to the pediatric operating mode and instructions specific to the adult operating mode.

7. The automated external defibrillator of claim 1 wherein the one or more computer processors are configured to enter the pediatric operating mode and, in response, cause the user interface to provide the instructions specific to the pediatric operating mode.

8. The automated external defibrillator of claim 7 wherein, when the automated external defibrillator is in the pediatric operating mode, the user interface is configured to omit chest compression feedback that is provided when the automated external defibrillator is in the adult operating mode.

9. The automated external defibrillator of claim 1 wherein the one or more computer processors are configured to enter the adult operating mode and, in response, cause the user interface to provide the instructions specific to the adult operating mode.

10. The automated external defibrillator of claim 1 wherein the user interface is configured to toggle between the instructions specific to the pediatric operating mode and the instructions specific to the adult operating mode when the control is used to toggle between the modes.

11. The automated external defibrillator of claim 10 wherein the user interface is configured to toggle between the instructions specific to the pediatric and adult operating modes during administration of one or more steps of resuscitation.

12. The automated external defibrillator of claim 11 wherein the user interface is configured to toggle between the instructions specific to the pediatric and adult operating modes during at least one of placing pads on the patient and administering CPR to the patient.

13. The automated external defibrillator of claim 1 wherein a level of the defibrillating shock is different for the pediatric operating mode and the adult operating mode.

14. The automated external defibrillator of claim 1 wherein when the operational mode is changed the one or more capacitors are discharged.

15. The automated external defibrillator of claim 1 wherein the control comprises a button including the indicator configured to provide the indication of the operating mode.

16. The automated external defibrillator of claim 1 wherein the indicator comprises at least one of a visual indicator, a lighted display, an audio indicator, a verbal indicator and a haptic indicator.

17. The automated external defibrillator of claim 1 comprising a motion sensor configured to generate motion signals arising from chest compressions applied to the patient, and wherein the one or more computer processors are configured to receive the generated motion signals arising from chest compressions applied to the patient and determine at least one of depth and rate of chest compressions based on the received motion signals.

18. The automated external defibrillator of claim 17 wherein, when the automated external defibrillator is in the adult operating mode, the one or more computer processors are configured to compare the at least one of depth and rate of chest compressions to a desired range and provide chest compression feedback to a user.

19. The automated external defibrillator of claim 18 wherein the chest compression feedback comprises at least one of visual feedback, audio feedback and haptic feedback.

20. The automated external defibrillator of claim 17 comprising a user interface configured to provide a visual display of numerical values of the determined at least one of depth and rate of chest compressions when the automated external defibrillator is set to a basic life support mode.

21. The automated external defibrillator of claim 20 wherein, when the automated external defibrillator is in the adult operating mode, the one or more computer processors are configured to compare the at least one of depth and rate of chest compressions to a desired range and provide chest compression feedback to a user.

22. The automated external defibrillator of claim 20 wherein, when the automated external defibrillator is in the pediatric operating mode, the user interface is configured to refrain from providing chest compression feedback to a user.

23. The automated external defibrillator of claim 1 wherein the one or more computer processors are configured to cause the one or more capacitors to be charged to a voltage that is greater when the operating mode is in the adult operating mode than when the operating mode is in the pediatric operating mode.
