3.3 Connection
3.3.1 ECG Connection
ECG measurement is to collect the ECG signal via the ECG electrodes. Electrode connects the patient and
the lead. The lead connects the monitor. The locations of the electrodes are very important for obtaining
accurate ECG signals.
1. Connect the cable to the right-panel connector marked with the ECG icon.
2. Select electrodes to be used. Use only one type of electrode on the same patient to avoid variations in
electrical resistance. For ECG monitoring, it is strongly recommended to use silver/silver chloride
electrodes. When dissimilar metals are used for different electrodes, the electrodes may be subject to
large offset potentials due to polarization. Using dissimilar metals may also increase recovery time after
defibrillation.
3. Prepare the electrode sites according to the electrode manufacture’s instructions.
The locations of the electrode are in the following Figure:
Figure 3.5 Locations of Electrodes
Note: If skin rash or other unusual symptoms develop, remove electrodes from patient.
4. After starting the monitor, if the electrodes become loose or disconnected during monitoring, the system
will display “LEAD OFF” on the screen to alarm the operator.
It might not display ECG wave with 3 leads. The 5 leads should be used to have
ECG wave.
5. The ECG leads and their corresponding locations are as follows:
Safety Instructions for ECG Monitoring

User Manual for Patient Monitor
11
Elegant-1100 Multi-parameter Patient Monitor can only be equipped with ECG leads provided by our
company; using ECG leads supplied by other companies may cause improper performance or poor
protection while using defibrillator.
Electric parts of electrodes, leads and cable are forbidden to contact any other conductive parts
(including ground).
Elegant-1100 Multi-parameter Patient Monitor can resist against defibrillator and electrosurgical unit.
Readings may be inaccurate for a short time after or during using defibrillator or electrosurgical unit.
Transient caused by cable circuitry blocks while monitoring may be similar to the near real heartbeat
waveform, as a result resistance heart rate alarm rings. If you put the electrodes and cable in proper
places according to this manual’s instructions and the instructions for using electrode, the chance of
this transient occurring will be decreased.
To the patient with pacemaker, due to that this device has been designed to provide resistance to
pacemaker signal interference, generally the pacemaker pulse is not counted in heart rate
measurement and calculation, but when the cycle time of pacemaker pulse is over 2ms, it may be
counted. In order to reduce this possibility, observe the ECG waveforms on the screen carefully and
do NOT rely entirely on the heart rate display and alarm system of this monitor when monitoring this
kind of patients.
Besides the improper connection with electrosurgical unit may cause burns, the monitor may be
damaged or arouse deviations of measurement. You can take some steps to avoid this situation, do
NOT use small ECG electrodes, choosing the position which is far away from the estimated Hertzian
waves route, using larger electrosurgical return electrodes and connecting with the patient properly.
ECG leads may be damaged while using defibrillator. If the leads are used again, please do the
functional check first.
3.3.2 Blood Pressure Cuff Connection
1. Connect the cable to the right-panel connector marked with the NIBP icon.
2. Select a cuff of appropriate size according to the age of the subject. Its width should be 2/3 of the length
of The upper arm. The cuff inflation part should be long enough to permit wrapping 50-80% of the limb
concerned. See the table below for the dimensions:
Note: The size of the cuff selected should suit the subjects while measuring.
Cuff Model
Arm Circumference
Cuff Width
Small-sized Pediatric Cuff
12cm ~ 19cm
11cm
Child Cuff
18cm ~ 26cm
8.4cm
Adult Cuff
25cm ~ 35cm
14cm
Large-sized Adult Cuff
33cm ~ 47cm
17.4cm
Prior to use of the cuff, empty the cuff until there is no residual air inside it to ensure accurate
measurement.
When putting on the cuff, unveil and wrap it around the upper arm evenly to appropriate
tightness as shown below.

User Manual for Patient Monitor

Figure 3.6 Cuff Position
When unplugging the cuff, hold the head of the connector and pull it out.
Safety Instructions for NIBP Monitoring
When taking the measure of an pediatric’s (less than 10 years old) blood pressure, do NOT operate
in the adult mode. The high inflation pressure may cause lesion or even body putrescence.
It is recommended to take the blood pressure measurement manually. Automatic measurement
should be used at the presence of a doctor/nurse.
NIBP monitoring is prohibited to those who have severe hemorrhagic tendency or with sickle cell
disease, or partial bleeding will appear.
Do NOT bind NIBP cuff on limbs with transfusion tube or intubations or skin lesion area, otherwise,
damages may be caused to the limbs.
Pay attention to the color and sensitivity of the limb when measuring NIBP; make sure the blood
circulation is not blocked. If blocked, the limb will discolor, please stop measuring or remove the cuff
to other positions. Doctor should examine this timely.
Do NOT twist the cuff tube or put heavy things on it.
3.3.3 To connect the SpO2
SpO2 probe is very delicate equipment. Please follow the steps and procedures in operating it. Failure to
operate it correctly can cause damage to the SpO2 probe.
Operation procedure:
1. Connect the SpO2 probe to the right panel’s jack labeled”SpO2”.When unplugging the probe, be
sure to hold the head of the connector and pull it out.
2. Insert one finger into the probe (index finger, middle finger or ring finger with proper nail length)
according to the finger mark on the probe, shown as below.
Figure 3.7 Demonstration of SpO2 Probe

User Manual for Patient Monitor
13
The scenario above will cause inaccurate reading or no readings during SpO2 measurement.
Safety Introductions for SpO2 Monitoring
Continuous use of fingertip SpO2 sensor may result in discomfort or pain, especially for those
patients with microcirculatory problem. It is recommended that the sensor should NOT be applied to
the same finger for over two hours.
SpO2 measuring position must be examined more carefully for some special patient. Do NOT install
the SpO2 sensor on the finger with edema or fragile tissue.
Do NOT put the SPO2 sensor and pressure cuff on the same limb, otherwise the NIBP measuring will
affect SpO2 measuring and cause the alarm error.
Do NOT use the damaged SpO2 sensor.
The SpO2 sensor can not be immerged into water, liquor or cleanser completely, because the sensor
has no capability of waterproofness.
Please do not allow the cable to be twisted or bended.
Please do not use nail polisher or other cosmetic product on the nail.
The finger should be of normal length.
