6.1 Preparation
1. Skin preparation
The quality of ECG information displayed on the monitor is a direct result of the
quality of the electrical signal received at the electrode. Proper skin preparation is
necessary for good signal quality at the electrode. A good signal at the electrode
provides the monitor with valid information for processing the ECG data. Choose
flat, non-muscular areas to place electrodes. Following is a suggested guideline for
skin preparation:
Shave hair from sites, if necessary.
Gently rub skin surfaces at sites to remove dead skin cells
Wash sites with soap and water (never use ether or pure alcohol, because this
increases skin resistance).
Dry the skin completely before applying the electrodes.
2. Attach the ECG lead to the electrodes prior to placement;
3. Place the electrodes on the patient. Use electrode gel prior to placement only if
pre-gelled electrodes are not used
4. Make sure the monitor is turned on and is ready for monitoring.

6.2 Electrode Placement
WARNING
z Use only the specified ECG cable for monitoring.
z When applying electrodes or connecting cables, make sure they are not
connected to any conductive part or the ground. Verify that all ECG
electrodes, including neutral electrodes, are securely attached to the
patient.
z Skin irritation may result from the continuous application of the ECG
electrodes. These should be checked each day. If there is an indication
of excess skin irritation, replace the electrodes or change the location of
the electrodes every 24 hours.
z Do not touch the patient, bed or instrument during defibrillation.
WARNING
z Interference from a non-grounded instrument near the patient and ESU
interference can cause inaccuracy of the ECG waveform.
z Always dispose of, or recycle electrodes properly to prevent from
environment contamination.
z Verify the lead fault detection prior to the start of monitoring. Unplug the
ECG cable from the ECG connector and the screen should display the
error message “ECG LEAD OFF” and an audible alarm should be
activated.

as QRS complex, hence leading to wrong HR readings or failure to
diagnose certain arrhythmia symptoms. Be sure to keep a close eye on
the patient wearing a pace-maker.
NOTE
z When PACE is set to ON, the system does not detect PVC-related
arrhythmia (including PVCs) resulting from pacemaker but still analyzes
the normal QRS complex.
z When the patient is not wearing a pacemaker, set PACE to OFF.
z When PACE is set to ON, missed beat (MIS) alarm is reported as pacer
not captured (PNC) or pacer not paced (PNP).

7.1 Principle of SpO2 Measurement
SpO2 monitoring is a non-invasive technique used to measure the amount of
oxygenated haemoglobin and pulse rate by measuring the absorption of selected
wavelengths of light. The light generated in the probe passes through the tissue and
is converted into electrical signals by the photodetector in the probe. The SpO2
module processes the electrical signal and displays on the screen digital values for
SpO2 and pulse rate.
7.2 Monitoring Procedure
Follow the procedure as below:
1. Power on the telemetry monitoring system.
2. Attach the sensor to the proper site on the patient.
3. Plug the connector of the sensor extension cable into the SpO2 connector on the
telemetry transmitter.
The SpO2 sensor selection and placement depend on the patient type. When
choosing a site for a sensor, refer to the directions for that sensor.

CAUTION
z The following factor may interfere with SpO2 measurement:
z Excessive light (suggestion: cover the sensor with something
non-transparent.)
z EM interference.
z Excessive patient movement.
z Presence of such substance as Hb-CO, Met-Hb or dye dilution chemicals.

7.4 Measurement Limitations
If the SpO2 reading seems incorrect, check the patient with another method, and then
check the system and SpO2 module. The following factors may interfere with the
SpO2 measurement:
Use of inappropriate SpO2 sensor.
High-frequency interference, or interference from ESU connected to the
system;
Oximeters and oximetry sensors used during magnetic resonance imaging
(MRI) scanning. Induced current could potentially cause burns;
Intravascular dye injections;
Excessive patient movement;.
Excessive ambient light;
Improper sensor installation or incorrect sensor placement on the patient
Sensor temperature (optimal temperature is between 28°C and 42°C);
The sensor is placed on a limb that is attached to a blood pressure cuff, arterial
catheter, or intravascular line;
Concentration of dysfunctional hemoglobin such as carboxyhemoglobin and
methemoglobin;
SpO2 too low;
Poor circular perfusion of the applied part;
Shock, anemia, low temperature and application of vasomotor all reduce the
arterial blood flow and may affect the pulse oximetry measurement
The absorption of oxyhemoglobin (HbO2) and deoxyhemoglobin to the light of
special wavelength may also affect SpO2 measurement. If there exist other
substances (like carbon hemoglobin, methemoglobin, methylene blue and indigo
carmine) absorbing the light of the same wavelength, they may result in false or low
SpO2 readings.

7.5 Warnings
WARNING
z The SpO2 value might be overestimated in the presence of Hb-CO,
Met-Hb or dye dilution chemicals.
z Do not use the SpO2 sensor if it’s packaging or the sensor is damaged.
Return them to the distributor or manufacturer.
z Verify sensor cable fault detection before beginning monitoring. Unplug
the SpO2 sensor cable from the connector. The screen displays the
prompt information “SpO2 SENSOR OFF” and the audible alarm is
activated.
z Do not tangle the sensor cable around the ESU cable.
z Do not place the sensor on the limb where an arterial catheter or
intravascular line is already placed.
WARNING
z Do not perform SpO2 and NIBP measurements on the same limb
simultaneously. Obstruction of blood flow during NIBP measurements
may adversely affect the reading of the SpO2 value.
z Prolonged and continuous monitoring may increase the risk of burns at
the site of the sensor. It is especially important to check the sensor
placement, and ensure proper attachment on neonates and patients of
poor perfusion or skin sensitive to light. Check the sensor location every
2 to 3 hours and move to another location if the skin deteriorates. More
frequent examinations may be required for different patients.
