Abstract

A resuscitation system that includes at least two defibrillation electrodes configured to be applied to the exterior of the chest of a patient for delivering a defibrillation shock, a source of one or more ECG signals from the patient, a defibrillation circuit for delivering a defibrillation shock to the defibrillation electrodes, a control box that receives and processes the ECG signals to determine whether a defibrillation shock should be delivered or whether CPR should be performed, and that issues instructions to the user either to deliver a defibrillation shock or to perform CPR, wherein the determination of whether CPR should be performed and the instructions to perform CPR can occur at substantially any point during a rescue. The control box may include a user operable control for initiating delivery of a defibrillation shock, and the instructions to deliver a defibrillation shock include instructions to activate the user operable control. The user operable control may be a button configured to be pushed by the user. The determination of whether CPR should be performed and the instructions to perform CPR may occur before a determination to deliver any defibrillation shock. The source of the ECG signals may be the defibrillation electrodes. The defibrillation circuit may be contained in the control box.

Claims

1. A resuscitation system, comprising:

at least one first high-voltage defibrillation electrode;

at least one second high-voltage defibrillation electrode; and

at least one manually operable control mechanically connected with and in the vicinity of at least one of the first and second electrodes; and

a resuscitation control system electrically connected to the first and second electrodes and the at least one manually operable control and configured to provide resuscitation prompts to a rescuer based on use of the manually operable control by the rescuer.

2. The resuscitation system of claim 1 wherein there are a plurality of manually operable controls mechanically connected with at least one of the first and second electrodes.

3. The resuscitation system of claim 1 wherein the at least one manually operable control comprises a pause control for pausing a resuscitation procedure.

4. The resuscitation system of claim 1 wherein the at least one manually operable control comprises a help button for requesting prompts from the resuscitation control system with respect to a particular aspect of resuscitation.

5. The resuscitation system of claim 4 wherein the particular aspect of resuscitation comprises clearing a patient'"'"'s airway.

6. The resuscitation system of claim 4 wherein the particular aspect of resuscitation comprises assisting a patient'"'"'s breathing.

7. The resuscitation system of claim 4 wherein the particular aspect of resuscitation comprises assisting a patient'"'"'s circulation.

8. The resuscitation system of claim 1 wherein the first electrode is a sternum electrode and the second electrode is an apex electrode.

9. The resuscitation system of claim 1 wherein the manually operable control is a button configured to be pushed by the user.

11. The CPR system of claim 9 wherein the manually operable control is a button configured to be pushed by the user.

10. A CPR system, comprising

a CPR pad configured to be located over a region of a patient'"'"'s body appropriate for CPR chest compressions;

a compression-sensing element interconnected with the CPR pad;

a resuscitation control system electrically connected to the compression-sensing element and configured to receive compression information from the compression-sensing element; and

at least one manually operable control mechanically connected with the CPR pad, wherein the resuscitation control system is electrically connected to the at least one manually operable control and is configured to provide resuscitation prompts to a rescuer based on use of the manually operable control by the rescuer.

12. A resuscitation system comprising:

at least two defibrillation electrodes configured to be applied to the exterior of the chest of a patient for delivering a defibrillation shock;

a source of one or more ECG signals from the patient;

a defibrillation circuit for delivering a defibrillation shock to the defibrillation electrodes;

a control box that receives and processes the ECG signals to determine whether a defibrillation shock should be delivered or whether CPR should be performed, and that issues instructions to the user either to deliver a defibrillation shock or to perform CPR;

wherein the determination of whether CPR should be performed and the instructions to perform CPR can occur at substantially any point during a rescue.

13. The system of claim 12 wherein the control box includes a user operable control for initiating delivery of a defibrillation shock, and the instructions to deliver a defibrillation shock include instructions to activate the user operable control.

14. The system of claim 13 wherein the user operable control is a button configured to be pushed by the user.

15. The system of claim 12 wherein the determination of whether CPR should be performed and the instructions to perform CPR can occur before a determination to deliver any defibrillation shock.

16. The system of claim 12 wherein the source of the ECG signals is the defibrillation electrodes.

17. The system of claim 12 wherein the defibrillation circuit is contained in the control box.
