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

3. A system as in claim 2 wherein the external chest compression device communication module is coupled to the at least one sensor.

4. A system as in claim 2 wherein the physiological data includes at least one attribute from the group consisting of pulse, heartbeat, breathing, body temperature, externally applied chest pressure and thoracic impedance.

5. A system as in claim 1 wherein the external chest compression device includes a chest compression member, the chest compression member including at least one pressure sensor disposed thereon and coupled to the first communication module.

6. A system as in claim 1 wherein the external chest compression device includes a manually operable chest compression member.

7. A system as in claim 1 wherein the external chest compression device includes a backboard and a ventilator operably coupled to the backboard.

8. A system as in claim 7 wherein the ventilator is coupled to the first communication module.

9. A system as in claim 1 wherein the first communication module and the second communication module utilize a wireless communications protocol selected from the group consisting of Bluetooth and 802.11.

11. A system as in claim 1 further comprising a first controller operably coupled to at least one of the external chest compression device and the defibrillator and configured to execute logic for coordinating external chest compression and defibrillation based on data transmitted between the first communication module and the second communication module.

12. A system as in claim 1, further comprising:

a first controller operably coupled to the external chest compression device and the first communication module, and

a second controller operably coupled to the defibrillator and to the second communication module.

13. A system as in claim 1, further comprising:
