Electrosurgical unit analyzers

Electrosurgical unit (ESU) analyzers automate the testing and inspection of the output circuits and safety features of ESUs. They perform testing that would otherwise require several other pieces of equipment, as well as considerably more time and greater technician expertise. They are used largely by clinical engineering departments for routine inspection and preventive maintenance (IPM) procedures and, less often, for accident investigations and troubleshooting. In this Evaluation, we tested three ESU analyzers from three suppliers. We rated all three analyzers Acceptable and ranked them in two groupings. In ranking the units, we placed the greatest weight on ease of use for routine ESU inspections, and gave additional consideration to versatility for advanced applications such as ESU research. The unit in Group 1 was the easiest to use, especially for infrequent users. The units in Group 2 were satisfactory but require more frequent use to maintain proficiency and to avoid user errors.
