Therefore, it is usually the smallest or sharpest electrode that generates the most heat. Cut/Coag Most wet field electrosurgical systems operate in two modes: "Cut" causes a small area of tissue to be vaporized, and "Coag" causes the tissue to "dry" (in the sense of bleeding being stopped). "Dried" tissues are killed (and will later slough or ...
The same techniques are also used to create higher tissue temperatures to destroy neoplasms (cancer and tumors), warts, and infected tissues; this is called hyperthermia treatment. In surgery diathermy is used to cauterize blood vessels to prevent excessive bleeding. The technique is particularly valuable in neurosurgery and surgery of the eye.
Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [1] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.

Because RF heating can heat foods more uniformly than is the case with microwave heating, RF heating holds promise as a way to process foods quickly. [8] In medicine, the RF heating of body tissues, called diathermy, is used for muscle therapy [9] Heating to higher temperatures, called hyperthermia therapy, is used to kill cancer and tumor tissue.
FILE - In this Thursday, July 1, 2021 file photo, a farmworker wipes sweat from his neck while working in St. Paul, Ore., as a heat wave bakes the Pacific Northwest in record-high temperatures. As ...
Bone hemostasis is the process of controlling the bleeding from bone.. Bone is a living vascular organ containing channels for blood and bone marrow. [1] When a bone is cut during surgery bleeding can be a difficult problem to control, especially in the highly vascular bones of the spine and sternum.

The use of hypothermia following cardiac arrest shows increased likelihood of survival. It is the re-warming period that, if not controlled properly, can have detrimental effects. Hyperthermia during the re-warming period shows unfavorable neurologic outcomes.
