Electro surgery Unit
Electrosurgical unit (ESU) emits a lot of RF interference. If the monitor is used with an
ESU, RF interference may affect the monitor operation.
Locate the monitor as far as possible from the ESU. Locate them on opposite sides of
the operating table, if possible.
Connect the monitor and ESU to different AC outlets located as far as possible from
each other.
When using this monitor with an electrosurgical unit, its return plate and the electrodes
for monitoring must be firmly attached to the patient. If the return plate is not attached
correctly, it may burn the patient’s skin where the electrodes are attached.
During surgery:
Use the appropriate orange electrode ECG safety cable, or lead cable with an red connector,
for measuring ECG in the operating room. These cables have extra circuitry to protect the
patient from burns during cautery, and they decrease electrical interference. This also
reduces the hazard of burns in case of a defective neutral electrode at the HF device. These
cables cannot be used for measuring respiration.
