Stimulation of nerves and muscles
Low-frequency currents stimulate nerves and muscles (Neuro-
muscular Stimulation)
Low-frequency currents arise either due to low-frequency power
sources or partial rectification of the HF current. Spasms or muscle
contractions can occur.
Risk of injury to the patient.
Set the effect as low as possible relative to the required surgical
effect. However, an effect level that is too low can be dangerous,
e.g. gas embolisms with the APC (Argon Plasma Coagulation), be-
cause the plasma does not ignite at an effect level that is too low.
Risks due to incorrect use of the return electrode
