Human skin burns induced by defibrillator default current
DL Stoner, JH Yoo, RW Feldtman and W Stanford
The attachment of various types of electronic instrumentation to a patient
can lead to hazardous interactions. Component malfunction in a single piece
of equipment connected to a patient may be totally innocuous. However, the
same fault occurring in an identical piece of equipment functioning as one
component in a network of monitoring and electrosurgical equipment can
result in severe burns or even electrocution. This paper describes
interaction between a defective defibrillator paddle and an electrosurgical
unit. Burns and ventricular fibrillation resulting from this malfunction
and interaction are described in detail and the electrical circuits are
analyzed.
