Method and apparatus for defrosting a defibrillation electrode
First Claim
1. An automated external defibrillator with defrosting capabilities comprising:
- a portable housing containing a battery powered energy source and a controller; and
at least a pair of electrodes operably coupled to the housing, the electrodes being releasably attachable to an external portion of a patient in need of resuscitation, each of the electrodes including a conductive interface medium having physical properties dependent upon a desired temperature range of about 32°
F. to 122°
F.;
wherein the controller is configured to selectively heat the conductive interface medium by applying a limited amount of electrical impulse from the energy source to raise the temperature of the conductive interface medium toward the desired range.

Abstract
A device and method for defrosting a defibrillation electrode are provided. This includes an automated external defibrillator that is capable of defrosting one or more frozen electrodes. The device is includes a portable housing containing a battery powered energy source and a controller as well as at least a pair of electrodes which are operably coupled to the housing. The electrodes are designed for attachment to the chest of a patient in need of resuscitation and contain a conductive interface medium that has temperature dependent properties. A controller is configured to selectively heat the conductive interface medium by applying limited electrical impulses and raise the electrode temperature to a desired temperature range.
