  • Page 152 Glossary Cutting When the generated heat causes the intracellular fluid to rapidly evaporate, then this results in an explosive burst of the cell membrane. To achieve this, a very high voltage of approximately 200 V is required. Such a high voltage generates sparks between the tissue and the instrument’s electrode/s.
