Abstract

Example defibrillator electrode assemblies compression assemblies are described that may be dimensioned and configured for use on a patient despite physical constraints that limit the area or locations on a patient onto which an electrode assembly may be placed. A cardio pulmonary resuscitation (CPR) assembly is also described that protects a patient with a transthoracic incision from further injury during application of CPR compressions proximate to the incision.

First claim

What is claimed is:

1. A method for using a defibrillation electrode assembly to provide resuscitative treatment to a patient, the method comprising:
applying a first therapy pad outside of a sterile field around an incision on the patient at a first location on the patient for administering one or more defibrillation currents to the patient, the first therapy pad comprising a first non-conductive substrate and a first electrically conductive layer in contact with the first non-conductive substrate, the first therapy pad having a length to width aspect ratio of between 3:1 and 30:1;
applying a second therapy pad outside of the sterile field around the incision on the patient at a second location on the patient for administering the one or more defibrillation currents to the patient, the second therapy pad comprising a second non-conductive substrate and a second electrically conductive layer in contact with the second non-conductive substrate, the second therapy pad having a length to width aspect ratio of between 3:1 and 30:1;
applying a third therapy pad to the patient at a third location on the patient for administering the one or more defibrillation currents to the patient, the third therapy pad comprising a third non-conductive substrate and a third electrically conductive layer in contact with the third non-conductive substrate, wherein the first therapy pad, the second therapy pad, and the third therapy pad are positioned so that the respective lengths of the first, second, and third therapy pads are aligned substantially parallel with respect to one another;
initiating application of a first defibrillation current between the respective electrically conductive layers of at least two therapy pads of the first therapy pad, the second therapy pad, and the third therapy pad such that a first vector of current travel occurs between the at least two therapy pads; and
initiating application of a second defibrillation current between the respective electrically conductive layers of two or more therapy pads of the first therapy pad, the second therapy pad, and the third therapy pad such that a second vector of current travel different from the first vector of current travel occurs between the two or more therapy pads.

2. The method of claim 1 , wherein applying the third therapy pad comprises applying the third therapy pad outside of a sterile field around an incision on the patient.

3. The method of claim 1 , wherein applying the first therapy pad, applying the second therapy pad, and applying the third therapy pad comprises applying the first, second, and third therapy pads to the patient so as to avoid a plurality of electrocardiography electrodes placed on the patient.

4. The method of claim 1 , further comprising placing a chest compression sensor within a sterile field around an incision on the patient.

5. The method of claim 4 , further comprising removing the chest compression sensor from a sterile pouch.

6. The method of claim 4 , wherein the chest compression sensor is placed over a sternum of the patient.

7. The method of claim 4 , further comprising detaching the chest compression sensor from the defibrillation electrode assembly.

8. The method of claim 1 , further comprising separating the first therapy pad from the second therapy pad.

9. The method of claim 8 , wherein separating the first therapy pad from the second therapy pad comprises tearing or cutting the first therapy pad from the second therapy pad along perforations between the first therapy pad and second therapy pad.

10. The method of claim 1 , wherein applying the first therapy pad and applying the second therapy pad to the patient comprises applying the first therapy pad on an upper chest of the patient and applying the second therapy pad on a side of the patient.

11. The method of claim 1 , wherein applying the first therapy pad, applying the second therapy pad, and applying the third therapy pad comprises applying the first therapy pad, the second therapy pad, and the third therapy pad to the patient so as to avoid a sensitive region of the patient.

12. The method of claim 11 , wherein the sensitive region comprises a transthoracic incision.

13. The method of claim 8 , wherein separating the first therapy pad from the second therapy pad comprises separating the first electrically conductive layer from the second electrically conductive layer.

14. The method of claim 8 , further comprising separating the third therapy pad from either the first or second therapy pads.

15. The method of claim 1 , further comprising removing the defibrillation electrode assembly from a sterile pouch.

16. The method of claim 1 , wherein applying the first therapy pad, applying the second therapy pad, and applying the third therapy pad comprises applying the first and second therapy pads onto a thorax of the patient, and applying the third therapy pad onto a posterior of the patient.

17. The method of claim 1 , wherein applying the first therapy pad and applying the second therapy pad comprises applying the first and second therapy pads on either side of a transthoracic incision on the patient.

18. The method of claim 1 , wherein applying the first therapy pad, applying the second therapy pad, and applying the third therapy pad comprises applying the first therapy pad to an anterior of the patient, applying the second therapy pad to a posterior of the patient, and applying the third therapy pad to the anterior of the patient.

19. The method of claim 1 , wherein applying the first therapy pad, applying the second therapy pad, and applying the third therapy pad comprises applying the first, second, and third therapy pads to the patient via first, second, and third adhesive layers, respectively.

20. The method of claim 19 , wherein applying the first therapy pad, applying the second therapy pad, and applying the third therapy pad comprises removing first, second, and third release layers from the first, second, and third therapy pads, respectively, before applying the first, second, and third therapy pads to the patient via the first, second, and third adhesive layers.
