Abstract

An apparatus and method is provided for a defibrillator that specifies treatment protocols in terms of number of chest compressions instead of time intervals. The defibrillator includes a connection port that is configured to attach with a plurality of electrodes that are capable of delivery of a defibrillation shock and/or sensing one or more physical parameters. An energy storage device capable of storing a charge is attached to the plurality of electrodes. A controller is coupled to the plurality of electrodes and the energy storage device, the controller is configured to provide CPR chest compression instructions in terms of the numbers of CPR chest compressions.

Claims

1. A defibrillator, comprising:

a connection port configured to couple the defibrillator to a plurality of electrodes configured to deliver a defibrillation shock and/or sense one or more physical parameters;

an energy storage device coupled to the plurality of electrodes and configured to store a charge; and

a controller coupled to the plurality of electrodes and the energy storage device, the controller configured to provide CPR chest compression instructions in terms of the numbers of CPR chest compressions.

2. The defibrillator of claim 1, wherein the CPR chest compression instructions include an initial number of chest compressions prior to an initial defibrillator pulse.

3. The defibrillator of claim 1, wherein the controller is further configured to perform an ECG analysis.

4. The defibrillator of claim 3, wherein the CPR chest compression instructions include an initial number of chest compressions prior to an initial ECG analysis.

5. The defibrillator of claim 3, wherein the CPR chest compression instructions include the number of chest compressions between an ECG analysis and a defibrillator pulse.

6. The defibrillator of claim 3, wherein the CPR chest compression instructions include the number of chest compressions between a defibrillator pulse and the next ECG analysis.

7. The defibrillator of claim 1, wherein the controller is further configured to provide optional CPR interval duration instructions in terms of time intervals for CPR treatment.

8. The defibrillator of claim 1, wherein the controller is further configured to monitor the number of CPR chest compressions given and initiate the charging of the energy storage device prior to a defibrillator pulse.

9. The defibrillator of claim 1, wherein the controller is further configured to aurally communicate at least the number of CPR chest compressions.

10. The defibrillator of claim 1, wherein the controller is further configured to count the number of chest compressions as they are administered.

11. The defibrillator of claim 10, wherein counting the number of chest compressions is based on a high frequency impedance.

12. The defibrillator of claim 1, wherein controller is further configured to:

count the number of chest compressions as they are administered; and

adjust the CPR chest compression instructions based at least in part on the number of chest compressions counted.

13. A defibrillator, comprising:

means for selecting a CPR treatment protocol from a plurality of stored CPR treatment protocols, the selected CPR treatment protocol including at least the number of CPR chest compressions; and

means for communicating the number of CPR chest compressions.

14. The defibrillator of claim 13, further comprising means for counting the number of chest compressions as they are administered.

15. The defibrillator of claim 13, further comprising means for performing an ECG analysis, and wherein the CPR treatment protocol includes an initial number of chest compressions prior to an initial ECG analysis.

16. The defibrillator of claim 15, wherein the CPR treatment protocol further includes the number of chest compressions between an ECG analysis and a defibrillation pulse.

17. The defibrillator of claim 13, further comprising:

means for monitoring the CPR treatment; and

means for adjusting the CPR chest compressions by selecting a new CPR treatment protocol from the plurality of stored CPR treatment protocols based at least in part on the monitored CPR treatment, the new CPR treatment protocol including at least the number of CPR chest compressions.

18. A method of operating a defibrillator in conjunction with the delivery of an injected medication, the method comprising:

selecting a CPR treatment protocol from a plurality of CPR treatment protocols corresponding to the injected medication, the CPR treatment protocol including at least chest compression and defibrillator pulse instructions; and

aurally communicating at least the number of chest compressions of the CPR treatment protocol.

19. The method of claim 18, further comprising:

counting the number of chest compressions as they are administered from the injection of the drug to the optimal condition for delivery of a defibrillator pulse; and

delivering a defibrillator pulse at the optimal condition.

20. The method of claim 19, further comprising:

monitoring the CPR treatment;

adjusting the CPR chest compressions by selecting a new CPR treatment protocol based at least in part on the monitored CPR treatment, the new CPR treatment protocol including at least chest compression; and

communicating at least the number of chest compression of the new CPR treatment protocol.
