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 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 a first set of CPR chest compression instructions corresponding to a first CPR protocol in terms of the numbers of CPR chest compressions, monitor the chest compressions as they are administered, determine the pattern of chest compressions being administered and provide a second set of CPR chest compression instructions corresponding to a second CPR protocol different from the first CPR protocol based on the determined pattern, wherein the first set of CPR chest compression instructions include an initial number of chest compressions prior to an initial defibrillator pulse.

2. 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.

3. 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.

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

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

6. The defibrillator of claim 5, wherein counting the number of chest compressions is based on a high frequency impedance.

7. 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 in the set of instructions being carried out based at least in part on the number of chest compressions counted.

8. A defibrillator, comprising:

a connection port configured to couple the defibrillator to a plurality of electrodes configured to deliver a defibrillation shock and 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 perform an ECG analysis, perform a first set of CPR chest compression instructions corresponding to a first CPR protocol in terms of the numbers of CPR chest compressions, monitor the chest compressions as they are administered, determine the pattern of chest compressions being administered and provide a second set of CPR chest compression instructions corresponding to a second CPR protocol different from the first CPR protocol based on the determined pattern, wherein the first set of CPR chest compression instructions include an initial number of chest compressions prior to an initial ECG analysis.

9. The defibrillator of claim 8, wherein at least one of the first set and the second set of the CPR chest compression instructions include the number of chest compressions between an ECG analysis and a defibrillator pulse.

10. The defibrillator of claim 8, wherein each of the first and the second set of CPR chest compression instructions includes the number of chest compressions between a defibrillator pulse and the next ECG analysis.

11. The defibrillator of claim 8, wherein the controller is further configured to provide optional CPR interval duration instructions in terms of time intervals for CPR treatment.

12. The defibrillator of claim 8, 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.

13. The defibrillator of claim 8, wherein the controller is further configured to aurally communicate at least the number of CPR chest compressions.

14. The defibrillator of claim 8, wherein the controller is further configured to count the number of chest compressions as they are administered.

15. The defibrillator of claim 14, wherein counting the number of chest compressions is based on a high frequency impedance.

16. The defibrillator of claim 8, wherein controller is further configured to:

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

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