Describe what is meant by 'Hot Can'

• A. Can is insulated from the shock vector
• B. Can is included in the shock vector/ circuit
• C. Can is the patient body
• D. Can is a safety device

Answer: (B)

The main idea is that during energy delivery, the current path can include the device housing itself. When the can is part of the shock vector, the current doesn’t just flow from electrode to electrode through the patient; it also passes through the device casing, meaning the can becomes energized or “hot.” This matters for safety and design: the case can carry voltage and must be considered in grounding, insulation, and handling during defibrillation or other high-energy delivery. So, describing a hot can means recognizing that the can is included in the current path of the shock circuit. It isn’t insulated from the shock path, it isn’t the patient, and it isn’t a safety device—the can’s role is to be part of the current circuit during discharge.
