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
