Skin-temperature distribution under a new type of defibrillating electrode.
The temperature rises under a new type of x-ray-transparent, improved current-density-distribution defibrillation electrode applied to pig skin were measured at four sites with fiberoptic thermal probes. Three anesthetized pigs, ranging in weight from 79 to 92 lb, were used. Temperature-time curves were obtained and the maximum temperature was identified. For 17 measurements at each site, the maximum temperature rise for a 360-joule shock was 317.3 +/- 53.0 millidegrees Celsius.
