ASGE Advanced Endoscopic Lesion Resection Course | November 2022-Understanding your Electrosurgical Unit

Video Transcription

Video Summary

In this video, the speaker discusses the practical aspects of using yellow and blue pedals for electrosurgical procedures. They cover topics such as current density, voltage, power, and their application in endoscopic surgery. The speaker distinguishes between pure cutting, pure coagulation, and blended current, and provides common starting settings for these procedures. They explain the different types of generators and how they work, including constant voltage, hybrid, and constant power generators. The speaker also provides insights into the physics behind electrosurgical units and the importance of understanding circuit impedance, resistance, and voltage. They explain the concept of power and its equation. The speaker emphasizes the importance of knowing the appropriate settings for different procedures, such as EMR and hemostasis, and provides examples and illustrations to support their explanations.
