Abstract

Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR) are described herein. A method for managing cardiopulmonary resuscitation (CPR) treatment to a person in need of emergency assistance includes monitoring, with an electronic medical device, a parameter that indicates a quality level of a CPR component being provided to the person by a user; determining, with the electronic medical device, that the parameter indicates that the quality level of CPR being provided is inadequate; and providing, to one or more rescuers of the person, an audible, visual, or tactile indication that a different person should perform the CPR component.

Claims

1. A method for managing cardiopulmonary resuscitation (CPR) treatment to a person in need of emergency assistance, the method comprising:

monitoring, with an electronic medical device, a parameter that indicates a quality level of a CPR component being provided to the person by a user;

determining, with the electronic medical device, that the parameter indicates that the quality level of CPR being provided is inadequate; and

providing, to one or more rescuers of the person, an audible, visual, or tactile indication that a different person should perform the CPR component.

2. The method of claim 1, further comprising repeating cyclically the actions of monitoring, determining, and providing, while multiple different people are instructed to perform the CPR component.

3. The method of claim 1, wherein the CPR component comprises chest compressions, and the parameter comprises depth of compression, rate of compression, or both.

4. The method of claim 3, further comprising generating a chest compression quality score from a combination of chest compression rate and chest compression depth, and providing the indication in response to the quality score falling outside a determined acceptable range.

5. The method of claim 3, further comprising providing information about a target chest compression depth with the electronic medical device.

6. The method of claim 3, further comprising providing periodic feedback to the user by displaying on a graphical display screen of the electronic medical device, an indication of values for depths of one or more of a plurality of chest compressions and an indication of a target compression depth.

7. The method of claim 6, wherein providing the periodic feedback to the user about chest compressions further comprises displaying on a graphical display screen of a defibrillator, a graphical representation of the depths of one or more of the plurality of the chest compressions and an indication of the target compression depth.

8. The method of claim 6, wherein providing the periodic feedback to the user about chest compressions further comprises displaying on a graphical display screen of a defibrillator, a graph having a visual indicia representing the target compression depth and visual indicia representing the values for the depths of one or more of the plurality of the chest compression displayed above or below the visual indicia representing the target compression depth.

9. The computer-implemented method of claim 1, further comprising displaying, on a first electronic display located on a thorax of the person in need of emergency assistance, information that provides instructions for performing CPR to one of the rescuers.

10. The computer-implemented method of claim 9, further comprising displaying, on a second electronic display and to another of the rescuers, information that provides instructions for performing CPR to one of the rescuers, the information provided on the first electronic display differing from the information provided on the second electronic display.

11. The computer-implemented method of claim 1, wherein the electronic device is connected to a defibrillation electrode on the person in need of emergency assistance.

12. The computer-implemented method of claim 1, further comprising providing, to a first of the one or more rescuers, an indication about the quality of chest compressions given to the patient, the indication about the quality chest compressions differing from the indication that a different person should perform the CPR component.

13. The computer-implemented method of claim 1, further comprising identifying a protocol for CPR being performed by the rescuers, and coordinating the providing of the indication that a different person should perform the CPR component with stored parameters that define the protocol, wherein the identified protocol is select from among multiple protocols stored on the electronic medical device.

14. A system for managing cardiopulmonary resuscitation (CPR) treatment to a person in need of emergency assistance, the system comprising:

an electronic patient monitor;

a sensor interface on the monitor arranged to receive input from one or more sensors that sense one or more that indicate a quality level of one or more CPR components being provided to the person in need of emergency assistance;

a CPR monitor in the electronic patient monitor programmed to use the input from the sensors to identify a quality parameter and to generate a signal to switch rescuers performing CPR when the quality parameter meets a determined criterion; and

an output interface in communication with the CPR monitor and arranged to provide rescuers using the electronic patient monitor with an indication to switch rescuers, in response to receiving the generated signal from the CPR monitor.

15. The system of claim 14, wherein the electronic patient monitor is part of an external patient defibrillator.

16. The computer-implemented system of claim 15, wherein the output interface comprises an electronic display attached to a connector that also is attached to defibrillator electrodes for connection to the external patient defibrillator.

17. The computer-implemented system of claim 16, wherein the electronic display is attached to one of the defibrillator electrodes and arranged so as to rest adjacent a rescuer'"'"'s hands when the electrode is properly placed on the person in need of emergency assistance, and the rescuer'"'"'s hands are placed for performing CPR chest compressions.

18. The computer-implemented system of claim 14, wherein the CPR monitor comprises a microprocessor connected to electronic memory that stores instructions that when executed perform a process of identifying a quality parameter and generating a signal to switch rescuers performing CPR when the quality parameter meets a determined criterion.

19. The computer-implemented system of claim 14, further comprising a sensor arranged to sense a quality level of chest compressions performed on the person is need of emergency assistance.

20. The computer-implemented system of claim 14, wherein the CPR monitor is further programmed to repeat cyclically actions of identifying the quality parameter, determining whether the quality parameter indicates a need to switch rescuers, and generating a signal to switch rescuers when the quality parameter indicates a need.

21. The computer-implemented system of claim 20, wherein the quality parameter reflects a depth of chest compressions, rate of compression, or both, of chest compressions performed on the person in need of emergency assistance.

22. The computer-implemented system of claim 14, further comprising a display arranged to provide feedback to a rescuer indicating a way to improve the one or more CPR components.

23. The computer-implemented system of claim 14, wherein the output interface comprises a wireless transmitter arranged to communicate data regarding the one or more CPR components to a rescuer of the person in need of emergency assistance.

24. The computer-implemented system of claim 14, wherein the first interface is arranged to communicate with a first display device for use by a first rescuer, and further comprising a second interface arranged to communicate with a second display device for use by a second rescuer, the second display device to communicate information about a CPR component that is different than information about a CPR component that is displayed on the first display device.
