Method and system for switching shock vectors and decreasing transthoracic impedance for cardioversion and defibrillation
First Claim
1. A device for performing cardioversion or defibrillation, which comprises:
- a first adhesive electrode patch for external application of an electrical shock to the chest of a patient;
second and third adhesive electrode patches to be applied to the back or back and a side of the patient, only one of which at a time can receive a shock vector from the first adhesive electrode patch;
a manual switching mechanism in electrical connection with each adhesive electrode patch; and
a cardioversion/defibrillator connector in electrical connection with the switching mechanism,wherein the switching mechanism has a switch to choose which of the second and third receiver adhesive electrode patches will receive the shock vector.

Abstract
A method and system improves the effectiveness of cardioversion or defibrillation through the ability to switch shock vectors and to reduce transthoracic impedance. An external multiple patch system comprises at least two options for a shocking vector once external patches are applied and adhered to desired locations on a patient'"'"'s body. A manual switching mechanism in the system provides the ability to direct current from a defibrillator to either of two or more adhesive electrode patches. A method and system of decreasing transthoracic impedance comprises wrapping material around a patient'"'"'s body to apply pressure to adhered patches, which further reduces transthoracic impedance by increasing effective pressure on the patches through use of pressure-focusing mechanisms located between a patch and a strap.
