Safety Precautions for Using the Equipment
Precautions about the System
Use only the accessories specified for this system. Otherwise, proper function cannot be executed.
Do not use the touch panel with the film attached. Malfunction of the touch panel or damage may result.
Due to its material characteristic, the touch panel expands/contracts depending on the temperature/humidity.
When the touch panel is left unused for a while, or when the ambient temperature is low, the surface film of
the touch panel may expand, but this is not an abnormal condition. This expansion will be reduced in few hours
or half a day after the power is turned ON.
When adjusting the angle of the display unit, pay attention not to have your hands get caught in between.
For quality improvement, specifications are subject to change without prior notice.
The display unit utilizes LED for the backlight. Since this LED deteriorates by the life cycle, the display may
become dark, scintillate, or may not light by the long term use. In such case, contact our service representative.
This equipment is intended to be used for only one patient.
The installation of this equipment should be performed by our service representative or a person who is well
acquainted with this equipment.
If not using for a long period, make sure to turn OFF the power of the main unit.
Precautions about the ECG Monitoring
If any electrodes get detached from the patient after being connected to the lead cable and patient monitor, pay
attention that the metal part of the electrode does not get in touch with any metal parts of the bed or any
conductive parts. Also, the operator should not touch any conductive parts with bare hands. Otherwise, it may
cause electric shock to the patient and/or operator due to excessive leakage current.
The indication for continuous use of the electrode is about one day.
Replace the electrode if the skin contact gets loosen due to perspiration, etc.
When an electrode is attached to the same location for a long period, some patients may develop skin irritation.
Check the patient's skin condition periodically and change the electrode site as required.
For stable arrhythmia detection and ECG monitoring, verify proper electrode placement, lead, waveform size,
and filter mode selection. If not properly selected, it may cause erroneous detection.
The threshold level for arrhythmia detection changes with ECG waveform size. Set a proper waveform size for
monitoring.
When the ECG waveform size is x1/4, x1/2, or x1, the arrhythmia detection level is 250 μV.
When the ECG waveform size is x2 or x4, the arrhythmia detection level is 150 μV.
The leads for arrhythmia detection, central monitor display, printing are fixed as ECG1 and ECG2. Set the most
appropriate leads with high QRS for ECG1 and ECG2, especially for arrhythmia detection. If the QRS
amplitude for the set lead is low, it may cause erroneous arrhythmia detection.
In ESIS Mode, artifacts such as electrosurgical noise or EMG can be largely reduced, but QRS amplitude
attenuation, waveform distortion, or ST segment change may occur compared with other filter modes.
The ESIS mode cannot completely reduce the electrical noise, and may erroneously detect the pacemaker
spike. This mode should be selected only when a high frequency noise largely affects the HR measurement.
There are some cases when the pacemaker pulse cannot be detected depending on the pacemaker type, pulse
voltage, pulse width, electrode lead type (unipolar, bipolar), or electrode placement which causes the
pacemaker pulse amplitude to decrease, and disables the pacemaker pulse detection.
If signals similar to a pacemaker pulse are present, such as electric blanket noise or excessive AC frequency
noise, these may be erroneously detected and displayed as a pacemaker pulse.
When a spontaneous QRS and pacemaker pulse overlap (ex. fusion beat, etc.), QRS detection cannot be
performed properly. In this case, the heart rate is degraded.
If a pacemaker pulse is continuously detected due to AC frequen
cy interference, QRS detection will be
sus
pended and the heart rate will be reduced. Arrhythmia will not be detected either.
