Abstract

Devices, methods, and software implementing those methods for providing communicating external chest compression (ECC) devices and defibrillation (DF) devices, where the ECC and DF devices can be physically separate from each other. Both ECC and DF devices are able to operate autonomously, yet able to communicate with and cooperate with another device when present. Some ECC and DF devices are adapted to be physically and/or electrically coupled to each other. One ECC device includes a backboard, a chest compression member, a communication module, controller, and at least one sensor, electrode lead or electrode. One DF device includes a defibrillator module, a controller, and a communication module that can communicate with the ECC communication module. The communicating ECC and DF devices may deliver ECC, pacing, defibrillation, ventilation, and cooling therapies, and may deliver instructions to human assistants, in a coordinated and cooperative fashion.

Claims

1. A method comprising:

placing a person on a first device;

establishing data communication between the first device and a second device that can be physically apart from the first device;

causing a chest compression member of the first device to compress a chest of the person against the backboard;

causing a defibrillator of the second device to defibrillate the person responsive to the communication; and

establishing a master device as between the first device and the second device.

2. The method as in claim 1, in which the master device coordinates chest compression and defibrillation.

3. A method comprising:

receiving an input that a person has been placed on an external chest compression (ECC) device;

generating instructions to establish communication between a first data communication module operably coupled to the ECC device and a second data communication module coupled to a defibrillator;

generating instructions to operate a chest compression member of the ECC device to compress the person against the backboard;

operating the defibrillator to defibrillate the person in response to the communication; and

generating instructions to establish a master controller as between a first controller coupled to the first data communications module and a second controller coupled to the second data communications controller.

4. The method of claim 3, further comprising generating voice outputs initiated by the master controller.

5. The method of claim 4, further comprising generating voice outputs.

6. The method of claim 4, in which the voice outputs include chest compression instructions.

7. The method of claim 4, in which the voice outputs include drug delivery instructions.

8. The method of claim 4, in which the voice outputs include manual ventilation instructions.

9. The method of claim 4, in which the voice outputs include instructions to cool the person.

10. The method of claim 4, in which the voice outputs include instructions to deliver a precordial thump.

11. The method of claim 4, in which the voice outputs include instructions to manually ventilate the person in synchrony with the chest compression instructions.

12. An article comprising:

a storage medium, the storage medium having instructions stored thereon, in which when the instructions are executed by at least one device, they result in;

receiving an input that a person has been placed on an external chest compression (ECC) device and a defibrillator and sending out the input as data;

establishing a master controller as between a first controller coupled to the ECC device and a second controller coupled to the defibrillator; and

generating instructions in the master controller to operate a chest compression member of the ECC device to compress the person'"'"'s chest.

13. An article as in claim 12, further comprising receiving a physiological signal of the person;

and operating the defibrillator to defibrillate the person in response to the received signal.

14. An article as in claim 12, in which the operating the defibrillator is controlled by the master controller.

15. An article as in claim 12, further comprising establishing communication between the ECC device and the defibrillator.

16. An article as in claim 15, in which the operating chest compression is performed responsive to the communication.

17. A system comprising:

an external chest compression (ECC) device having a first communication module;

a defibrillator havina a second communication module,

in which the ECC device and the defibrillator are capable of communicating via the first communication module and the second communication module;

a first controller and a second controller,

in which the first controller is operably coupled to the ECC device and to the first communication module, in which the second controller is operably coupled to the defibrillator and to the second communication module;

in which the first and second controllers are configured to designate a master controller from one of the first and second controllers.

18. A system as in claim 17, further comprising at least one sensor coupled to at least one of the first and second controllers, in which the master controller includes logic to initiate defibrillation responsive to sensor data indicative of cardiac arrest.

19. A system as in claim 17, further comprising at least one sensor coupled to at least one of the first and second controllers, in which the master controller includes logic to initiate defibrillation responsive to sensor data indicative of ventricular fibrillation.

20. A system as in claim 17, further comprising at least one sensor coupled to at least one of the first and second controllers, and further comprising a cooling module, in which the master controller initiates cooling using the cooling module responsive to sensor data indicative of cardiac arrest in the person.

21. A system as in claim 20, further comprising a human interface module for communicating with a human assistant, in which the master controller initiates the cooling through instructions issued to the human assistant through the human interface module.

22. A system comprising:

an external chest compression (ECC) device having a first communication module;

a defibrillator having a second communication module,

in which the ECC device and the defibrillator are capable of communicating via the first communication module and the second communication module;

a chest compression member,

an electrode disposed on the chest compression member, and

a first electrical connector electrically coupled to the chest compression member electrode,

in which the defibrillator includes a second electrical connector adapted to connect to the first electrical connector, and

in which the first or second controller executes logic to accept data indicative of the length of cardiac arrest, and in which the first or second controller executed logic to perform external chest compression prior to administering a defibrillation pulse if the length of cardiac arrest is greater than a time limit.
