ECG with HF surgery
To prevent interference and ensure patient and staff
safety, observe the following during HF surgery:
z On the HF surgery device, select the neutral
electrode with the largest contact surface and
place it as near as possible to the operation site.
z Ascertain the heart rate via the SpO
2 signal or
arterial blood pressure instead of via the ECG.
z Internal temperature sensors (rectal, esopha-
geal) have a protective sheath.
Interference from other sources
The use of infusion or reel pumps or other electrical
devices during patient monitoring may lead to ECG
artefacts, whereby Zeus IE might display pace-
maker markers although the ECG is normal.
To determine the interference source, the corre-
sponding device may need to be switched off. If this
eliminates the artefacts, the device is probably the
cause of the interference.
Electrical interference emitted from insulation com-
ponents can briefly overlap or interrupt the ECG
signal.
The signals from transcutaneous electrical nerve
stimulators (TENS) are similar to pacemaker
pulses and can be misinterpreted as such by
Zeus IE. Valid QRS complexes after a misinter-
preted TENS signal may possibly be rejected by
Zeus IE.
WARNING
ECG leads, temperature sensors, pressure
measuring accessories, SpO2 sensors, and in-
termediate cables must be kept away from the
grounding as well as the electrosurgical de-
vice and its cables.
WARNING
When using HF surgery devices, only use blue
Dräger ECG leads or a high-frequency adapter
block for conventional cables, see separate
list of accessories. The blue leads and the
adapter block guard against high-frequency
interference and protect the patient against
burns, which can be caused by voltage being
emitted by the HF surgery device.
WARNING
When using a high-frequency adapter block
and blue shielded cables, pacemaker detec-
tion is not available. This also applies when
the ESU ECG filter is selected.
