Abstract

A method and apparatus are provided for distributing power within a cardiac treatment and monitoring system which includes a defibrillator releasably coupled to a patient monitoring unit. The method includes the steps of determining a battery reserve capacity within the patient monitoring unit and distributing power from the patient monitoring system to a defibrillator when the determined battery reserve capacity exceeds a threshold value.

Claims

5-1. The cardiac treatment and monitoring system as in claim 1 further comprising a power switch disposed within the patient analyzer unit and adapted to couple power from the plurality of batteries to the defibrillator when the battery capacity analyzer determines that a reserve capacity of the plurality of batteries exceeds a threshold value.

6. A method of distributing power within a cardiac treatment and monitoring system which includes a defibrillator releasably coupled to a patient monitoring unit, such method comprising the steps of:

determining a battery reserve capacity within the patient monitoring unit; and

distributing power from the patient monitoring system to a defibrillator when the determined battery reserve capacity exceeds a threshold value.

7. The method of distributing power as in claim 6 wherein the step of determining a battery reserve capacity further comprises determining a number of batteries coupled to the patient monitoring system.

8. The method of distributing power as in claim 7 wherein the step of determining a battery reserve capacity further comprises determining the number of batteries coupled to the patient monitoring system exceeds a number of batteries coupled to the defibrillator.

9. The method of distributing power as in claim 7 wherein the step of determining a battery reserve capacity further comprises determining a charge reserve capacity remaining within batteries coupled to the patient monitoring system.

10. The method of distributing power as in claim 6 further comprising providing power to the defibrillator from an alternating power source.

11. The method of distributing power as in claim 6 further comprising powering the defibrillator from a defibrillator battery during charging of a shock capacitor of the defibrillator.

12. The method of distributing power as in claim 6 further comprising powering a battery charger within the defibrillator for charging the defibrillator battery.

13. An apparatus for distributing power within a cardiac treatment and monitoring system which includes a defibrillator releasably coupled to a patient monitoring unit, such apparatus comprising:

means for determining a battery reserve capacity within the patient monitoring unit; and

means for distributing power to a defibrillator when the determined battery reserve capacity exceeds a threshold value.

14. The apparatus for distributing power as in claim 13

wherein the means for determining a battery reserve capacity further comprises means for determining a number of batteries coupled to the patient monitoring system.

15. The apparatus for distributing power as in claim 14

wherein the means for determining a battery reserve capacity further comprises means for determining the number of batteries coupled to the patient monitoring system exceeds a number of batteries coupled to the defibrillator.

16. The apparatus for distributing power as in claim 14 wherein the means for determining a battery reserve capacity further comprises means for determining a charge reserve capacity remaining within batteries coupled to the patient monitoring system.

17. The apparatus for distributing power as in claim 13

further comprising means for providing power to the defibrillator from an alternating power source.

18. The apparatus for distributing power as in claim 13

further comprising means for powering the defibrillator from a defibrillator battery during charging of a shock capacitor of the defibrillator.

19. The apparatus for distributing power as in claim 13

further comprising means for powering a battery charger within the defibrillator for charging the defibrillator battery.

20. An apparatus for distributing power within a cardiac treatment and monitoring system which includes a defibrillator releasably coupled to a patient monitoring unit, such apparatus comprising:

a battery reserve capacity analyzer adapted to determine a battery reserve capacity within the patient monitoring unit; and

a power distribution system adapted to distribute power to a defibrillator when the determined battery reserve capacity exceeds a threshold value.

21. The apparatus for distributing power as in claim 20

wherein the battery reserve capacity analyzer further comprises a plurality of battery sensors adapted to alert the battery reserve capacity analyzer when a battery is coupled to the patient monitoring system.

22. A cardiac treatment and monitoring system comprising:

a cardiac analyzer unit adapted to detect and analyze a QRS complex of a patient;

a defibrillator unit adapted to receive QRS information of the analyzed QRS complex from the cardiac analyzer; and

a power distribution system disposed within the cardiac analyzer unit and adapted to conditionally share power from a power source of the cardiac analyzer with the defibrillator.
