Current Density Imaging and Electrically Induced Skin Burns Under Surface Electrodes

Detecting Skin Burns Induced by Surface Electrodes

The origin of electrical burns under gel-type surface electrodes is a controversial topic that is not well understood. To investigate the phenomenon, we have developed an excised porcine skin+gel model. In the present paper, we describe methods to detect these burns in the skin+gel model in an effort to understand the genesis of these burns. Burns were induced by severe electrical stimulation a...

Estimation of current density distribution under electrodes for external defibrillation

BACKGROUND Transthoracic defibrillation is the most common life-saving technique for the restoration of the heart rhythm of cardiac arrest victims. The procedure requires adequate application of large electrodes on the patient chest, to ensure low-resistance electrical contact. The current density distribution under the electrodes is non-uniform, leading to muscle contraction and pain, or risks...

Evaluation of current distribution induced on perfect electrically conducting scatterers

Airbag-Induced Thermal Skin Burns

Two new techniques for investigating the thermal skinburn potential of airbags are presented. A reduced-volume airbag test procedure has been developed to obtain airbag pressures that are representative of a dynamic ridedown event during a static deployment. Temperature and heat flux measurements made with this procedure can be used to predict airbag thermal burn potential. Measurements from th...

Re-usage of external pacing electrodes results in skin burns.

A 29 year old woman with a background of poorly controlled iabetes was admitted to our hospital in cardiogenic shock due o acute inferior myocardial infarction and complete heart block. ecycled external electrodes (“stat.padz®”) were placed to the right f the upper sternal border below the clavicle and to the left of he nipple with the centre of the electrode in the mid-axillary line. xternal p...
