2.3.3. Hazard-free patient positioning
► Position patients so that they are not touching any metal parts that
are grounded or have considerable capacitance relative to ground
(e.g. operating table brackets). If necessary, place anti-static cloths
between the patient and the bedding.
► Ensure that the patient does not touch any wet clothes or bedding.
► Place anti-static cloths between areas with heavy sweating and skin-
to-skin contact areas on the patient’s torso.
► Ensure that the patient is resting on a suitable surface in order to
prevent pressure necrosis.
► Drain urine via a catheter.
2.3.4. Correct connection of the HF device
► Always ground the HF device to the equipotential rail.
Also observe the requirements in Section 8.6.7 of IEC 60601-1
regarding medical electrical systems.
► Do not use needle electrodes for monitoring.
► Attach electrodes of physiological monitoring devices without
protective resistors or HF chokes as far away from the HF electrodes
as possible.
► In all cases, monitoring systems containing devices to limit the high-
frequency current are recommended.
► Place lines from monitoring devices so that they do not lie on the
patient’s skin.
► Keep the leads to the HF electrodes as short as possible and
position them so that they do not touch the patient or other leads.
► Do not place any objects on the HF device.
2.3.5. Correct use of the HF device
Inadvertent activation of the HF device outside the user’s field of vision can
injure the patient.
► Activate the HF device only when the electrode is in your field of
vision and you can quickly deactivate the HF device at all times.
► If the HF device is activated inadvertently, switch it off immediately
using the on/off switch.
► Take particular care when using a foot switch or manual switch.
Improper preparation, user errors or faults in the HF device can cause
damage to the HF device.
► Use the automatic monitoring functions to ensure that the HF device
is working properly. See Section Functional testing, page 33 for
information on the auto test functions.
► Ensure that no conductive fluids (e.g. blood or amniotic fluid) have
penetrated the foot switch or the manual switch.
► Ensure that the cables for the foot switch and the manual switch are
free from short circuits and broken leads.
