East Central Community College ST P&P Ch.17 Active electrode vs. return electrode - CORRECT ANSWER-Electrode of an electrotherapy device that is used on the area to be treated A safety system used ... in electrosurgery in which the PRE transmits continuous feedback on the quality of impedance in the electrode and stops the current when it becomes dangerously high. Alternating current vs. direct current - CORRECT ANSWER-Abbreviated AC; rapid and interrupted current, flowing first in one direction sand then in the opposite direction; produced by mechanical means and changes direction 60 times per second Direct current that flows in One Direction only. It has a low voltage current. Used in batteries Amplification vs. frequency (of a wave) - CORRECT ANSWER-In wave science, the phenomenon of increasing wave height by lining up the peaks and troughs of individual waves. The number of waves cycles that occur in one second. Cauterization vs. electrosurgery - CORRECT ANSWER-Direct application of hot implements to sterilize wounds and stop hemorrhage. The direct use of electricity to cut and coagulate tissue. Coagulum vs. eschar - CORRECT ANSWER-A sticky, semi liquid substance that forms when tissue is altered by electrical or ultrasonic energy Charred tissue created by high voltage current Monopolar circuit vs. bipolar circuit - CORRECT ANSWER-Continuous path of electricity that flows from the ESU to the active electrode, through the patient and the return electrode, and back to the ESU Travels from the power unit through forceps that have opposite poles and are in contact with tissue and then returns to the energy source The body reacts to electricity according to the voltage and frequency. High __ is potentially more dangerous than low __. High __ is less dangerous than low __. - CORRECT ANSWER-voltage voltage frequency frequency The direct application of a he [Show More]
