The 3-lead patient cable cannot be used with this

ECG Acquisition via Separate ECG
Electrodes and Patient Cable
Use only silver/silver-chloride electrodes to
acquire the ECG signal. These electrodes prevent
polarization voltages which may be caused by the
defibrillation shock, resulting in an ECG trace on
the monitor screen or recording that simulates
cardiac arrest. The ECG can be picked up with 5
or with 10 electrodes (for ECG measurement,
however, 10 ECG electrodes are required (chapter
8)).
•
Apply the electrodes as shown in Figure 4-13.
•
Plug the block of leadwires (N, R, L, F, C1)
into the patient cable (Figure 4-14).
•
Connect the patient cable to the device (Figure
4-15).
•
Turn on the device (energy selector to ).
On the monitor screen you will now see the 3 ECG
leads selected in the setup menu (factory defaults:
leads I, II, III).
Warning
Shock Hazard / Equipment Damage — All patient
signal inputs labeled with the symbol are
protected against damage resulting from defibril-
lation and electrocautery voltages. For this reason,
patient safety and device protection are ensured
during defibrillation and HF surgery.
Nevertheless, extreme care should be exercised when
electrosurgery devices are used on a patient who is
connected to other devices. As a general rule, a
minimum distance of 15 cm between the ECG and
electrosurgery electrodes should be maintained. If
this is not ensured, temporarily disconnect the elec-
trodes and transducer leads while using the electro-
surgery device.
Great care must be exercised to prevent that conduc-
tive parts (connectors, electrodes, transducers) con-
nected to the isolated patient signal input come in
contact with other grounded conductive parts, as this
could bridge the patient's isolation and cancel the
protection provided by the isolated input. It is par-
ticularly important that the neutral electrode does
not come in contact with ground.
