Figure 4-1: Neutral electrode modes
Faults related to the neutral electrode and possible remedies are shown on the
display, see Section Detecting and correcting faults, page 73.
4.5.2. EASY neutral electrode monitoring (EASY monitoring)
The maximum output power of monopolar current types is reduced to
50 W when a children’s electrode is selected.
The EASY monitoring function measures changes in the resistance between the
patient and the high-frequency surgery device before and during HF activation. If
necessary, it generates visual and audible alarms to request staff intervention. This
requires using a split neutral electrode with appropriate contact areas and suitable
contact resistance, attached to the patient according to the manufacturer’s
instructions. The EASY system does not monitor the currents through the
individual contact surfaces of the split neutral electrode.
An electrode with a surface area of at least 110 cm² must be used for the
"Resection" programs and the "Moderate Coagulation" mode.
If an error message is generated, the display changes from green via yellow to red,
depending on the type of fault.
NOTE
Risk of incorrect application of the neutral electrode
Ensure compliance with the specifications for correct attachment of
the neutral electrode with regard to size, adhesive properties and
full-surface contact of the complete electrode.
