Abstract

A method and apparatus for identifying electrodes attached to a defibrillator and adjusting patient therapy delivered by a defibrillator in response thereto.

Claims

1. A defibrillator comprising:

at least one electrode pad having an electrode pad type operable to contact a patient;

a medical electrode connector, connected to the defibrillator electrode pad on one end and the defibrillator on the other end, and including a magnet which is operable to identify the electrode pad type to the defibrillator;

a front-end circuit operation to be coupled to the electrode pad and to receive identification information from the electrode pad;

a shock delivery circuit coupled to the electrode pad; and

a processor coupled to the front-end and shock delivery circuits and operable to determine whether the patient is experiencing a shockable heart condition and to enable the shock-delivery circuit to deliver a shock to the patient via the electrode pads if the processor determines that the patient is experiencing a shockable heart condition,

wherein the defibrillator further comprises means for detecting the magnetic field produced by the magnet when the medical electrode connector is connected to the defibrillator to identify the electrode pad type to the defibrillator.

2. The defibrillator of claim 1 wherein the medical electrode connector is removably connectable to the defibrillator.

3. The defibrillator of claim 1 wherein the means for sensing further comprises means for sensing the number of magnets in the medical electrode connector.

4. The defibrillator of claim 1 wherein the medical electrode connector has a plurality of magnets to identify the electrode pad type to the defibrillator.

5. A method of deploying a defibrillator comprising:

tuning the defibrillator on;

attaching electrode pads to a patient;

inserting a cable connector containing a magnet which is associated with the electrode pads into a housing for receiving the cable connector within the defibrillator;

identifying the type of electrode pads based on the magnet within the cable connector associated with the electrode pads, wherein said identifying step further comprises the step of detecting the magnetic field of the magnet within the defibrillator; and

altering therapy delivered by the defibrillator based on the type of electrode pads identified.

6. The method of claim 5 further comprising the step of:

adjusting the amount of energy delivered to a patient in response to the electrode pad identification.

7. The method of claim 5 further comprising the step of:

lowering the amount of energy delivered to a patient if the electrodes are identified as infant electrodes.

8. The method of claim 5 further comprising the step of:

lowering the amount of energy delivered to a patient if the electrodes are identified as child electrodes.

9. The method of claim 5 further comprising the step of:

following a default therapy protocol if the electrode identification is not recognized.

10. The method of claim 5 further comprising the step of:

following a default therapy protocol if no electrode identification is recognized.

11. The method of claim 5 further comprising the step of:

altering a CPR patient treatment protocol to conform to the type of patient being treated.

12. The method of claim 5 further comprising the step of:

indicating use of the infant CPR protocol if the electrodes are identified as infant electrodes.

13. The method of claim 5 further comprising the step of:

indicating use of the child CPR protocol if the electrodes are identified as child electrodes.

14. The method of claim 5 further comprising the step of:

following a default CPR protocol if the electrode identification is not recognized.

15. The method of claim 5 further comprising the step of:

following a default CPR protocol if no electrode identification recognized.

16. The method of claim 5 further comprising the step of:

indicating use of the CPR protocol recommended by the American Heart Association if the electrodes are identified as AHA electrodes.

17. The method of claim 5 further comprising the step of:

indicating use of the CPR protocol recommended by the European Resuscitation Council if the electrodes are identified as ERC electrodes.

18. The method of claim 5 further comprising the step of:

indicating use of the CPR protocol recommended by specific organizations if the electrodes are identified as electrodes specific to that organization.

19. The method of claim 5, wherein identifying the type of electrode pads further comprises identifying the number of magnets within the cable connector.
