1.5 Built-in Battery

1.5.1 Introduction

The monitor can be fitted with rechargeable battery to ensure its continuous work after the failure of
alternating current power supply, and it needs no special maintenance under the normal condition.
While the monitor connecting with alternating current power, no matter whether the monitor is
operating or not, the battery always can be charged. In the event of sudden being powered off, the
monitor will automatically get power supply from battery without interruption of monitoring work.
Indicative message under the screen will display battery states:

16
 Indicates that the battery is fully charged.
Indicates that the battery is half charged.
Indicates that the battery is almost depleted and need to be charged
immediately.
Indicates that the battery is being charged.
Indicates that the AC mains is connected.

The power supply of battery can only function for a certain period. Excessively low voltage of
battery will trigger a technical alarm and the “Battery Low” message will be displayed. At this
moment, the monitor shall immediately connect with alternating current power supply to charge the
battery.

Caution
Remove the batteries prior to shipping or if the monitor is not likely to be used for an extended
period of time.

Warning
Use only batteries specified in this manual.
Keep the batteries out of children’s reach.

1.5.2 Installing a Battery

The battery compartment is in the bottom part of the monitor, please refer to the following steps
when installing or charging the batteries.
1. Turn off power of the monitor, and disconnect the power wire and other connected wires.
2. Open the battery door towards the direction labeled on it.
3. Take out the old battery.
4. Insert the new battery towards the direction labeled.
5. Close the battery door.

1.5.3 Optimizing Battery Performance

A battery needs at least two optimizing cycles when it is put into use for the first time. A battery
cycle is one complete, uninterrupted charge of the battery, followed by a complete, uninterrupted
discharge of the battery. A battery should be conditioned regularly to maintain its useful life.
Condition a battery once when it is used or stored for two months, or when its run time becomes
noticeably shorter.
To optimize a battery, follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring and measuring procedures.
2. Place the battery in need of optimizing into the battery compartment to the monitor.
3. Place the monitor in the charger stand and connect the AC mains. Allow the battery to be charged
uninterruptedly for above 6 hours.
4. Remove the AC mains and allow the monitor to run from the battery until it shuts off.
5. Replace the monitor in the charger stand and connect the AC mains. Allow the battery to be
17
charged uninterruptedly for above 6 hours.
6. The optimizing of the battery is over.

1.5.4 Checking Battery Performance

The performance of a battery may deteriorate over time. To check the performance of a battery,
follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring and measuring procedures.
2. Place the monitor in the charger stand and connect the AC mains. Allow the battery to be charged
uninterruptedly for above 6 hours.
3. Disconnect AC mains and allow the monitor to run on the battery until it shuts off.
4. The operating time of a battery reflects its performance directly.

Caution
The operating time of a battery depends on the configuration and operation of the monitor.
NIBP measurement, SpO2 measurement and using of recorder will deplete the battery faster
than other parameters’ measurement.

1.5.5 Disposing Batteries

Batteries that are damaged or depleted should be replaced and discarded properly. Dispose of used
batteries according to local regulations.

Caution
The service life of battery depends on the service time and frequency. This monitor battery can
be charged and discharged for 300 times generally.

Warning
Do not disassemble batteries, or dispose of them in fire, or cause them to short circuit. They
may ignite, explode, or leak, causing personal injury.

Chapter 4 Patient Safety

The Portable Patient Monitor is designed to comply with the International National Safety
requirements for medical electrical equipment. This device has floating inputs and is protected
against the effects of defibrillation and electrosurgery. If the correct electrodes are used and applied
in accordance with the manufacturer instructions, the screen display will recover within 10 seconds
after defibrillation.

This symbol indicates that the instrument is IEC60601-1 Type CF equipment. The unit displaying
this symbol contains an F-Type isolated (floating) patient applied part providing a high degree of
protection against shock, and is suitable for use during defibrillation.

Warning
Do not touch the patient, bed or instrument during defibrillation.

Environment

Follow the instructions below to ensure a completely safe electrical installation. The
environment where the Portable Patient Monitor will be used should be reasonably free from
vibration, dust, corrosive or explosive gases, extremes of temperature, humidity, and so on. For
a cabinet mounted installation, allow sufficient room at the front for operation and sufficient
room at the rear for servicing with the cabinet access door open.

The Portable Patient Monitor operates within specifications at ambient temperatures between 0℃
and 40℃. Ambient temperatures that exceed these limits could affect the accuracy of the instrument
and cause damage to the modules and circuits. Allow at least 2 inches (5cm) clearance around the
instrument for proper air circulation.

Grounding the Portable Patient Monitor

To protect the patient and hospital personnel, the cabinet of the Portable Patient Monitor must be
grounded. Accordingly, the Portable Patient Monitor is equipped with a detachable 3-wire cable
which grounds the instrument to the power line ground (protective earth) when plugged into an
appropriate 3-wire receptacle. If a 3-wire receptacle is not available, consult the hospital electrician.
If completeness of the protective grounding wire is in doubt, the equipment must be operated with
internal power supply.

Warning
Do not use a 3-wire to 2-wire adapter with this instrument.

41
Connect the grounding wire to the equipotential grounding terminal on the main system. If it is not
evident from the instrument specifications whether a particular instrument combination is hazardous
or not, for example due to summation of leakage currents, the user should consult the manufacturers
concerned or else an expert in the field, to ensure that the necessary safety of all instruments
concerned will not be impaired by the proposed combination.

Equipotential Grounding

Protection class 1 instruments are already included in the protective grounding (protective earth)
system of the room by way of grounding contacts in the power plug. For internal examinations on
the heart or the brain, the Portable Patient Monitor must have a separate connection to the
equipotential grounding system. One end of the equipotential grounding cable (potential equalization
conductor) is connected to the equipotential grounding terminal on the instrument rear panel and the
other end to one point of the equipotential grounding system. The equipotential grounding system
assumes the safety function of the protective grounding conductor if ever there is a break in the
protective grounding system. Examinations in or on the heart (or brain) should only be carried out in
medically used rooms incorporating an equipotential grounding system. Check each time before use
that the instrument is in perfect working order. The cable connecting the patient to the instrument
must be free of electrolyte.

Warning
If the protective grounding (protective earth) system is doubtful, the monitor must be supplied
by inner power only.

Condensation

Make sure that during operation, the instrument is free of condensation. Condensation can form
when equipment is moved from one building to another, thus being exposed to moisture and
differences in temperature.

Warning
Possible explosion hazard if used in the presence of flammable anesthetics.

Explanation of Symbols in the Monitor

This symbol means 'BE CAREFUL '. Refer to the manual.

This symbol indicates that the instrument is IEC60601-1 Type CF equipment. The unit displaying
this symbol contains an F-Type isolated (floating) patient applied part providing a high degree of
protection against shock, and is suitable for use during defibrillation.

Chapter 6 Alarm

Alarm refers to a prompt that is given by the monitor for medical personnel through visual, audible
and other means when a vital sign appears abnormal or the monitor occurs technical problem.

Note
The monitor generates all the audible and visual alarms through speaker, alarm lamp and
screen. When the monitor powers on, the alarm lamp will be lighted one time and the speaker
will give a beep voice, which indicates the alarm system of the monitor is working order.

6.1 Alarm Category

According to character of alarm, the monitor’s alarms can be classified into three categories:
physiological alarms, technical alarms and prompt messages.
 Physiological alarms
Physiological alarms are triggered by a monitored parameter value that violates set alarm limits or an
abnormal patient condition. Physiological alarm message are displayed in the physiological alarm
area.
 Technical alarms
Technical alarms are triggered by a device malfunction due to improper operation or system
problems. The problems may result in system abnormal operation or irresponsible monitoring
parameters. Technical alarm message are displayed in the technical alarm area.
 Prompt messages
As a matter of fact, prompt messages are not alarm messages. Apart from the physiological and
technical alarm messages, the monitor will show some message to indicate the system status.

6.2 Alarm Level

According to severity of alarm, the monitor’s physiological alarms are classified into three
categories: high level alarms, medium level alarms and low level alarms.

 High level alarms: Indicate that the patient is in a life threatening situation and an
emergency treatment is necessary. This is the highest level alarm.
 Medium level alarms: Indicate that the patient’s vital signs appear abnormal and an
immediate treatment is required.
 Low level alarm: Indicate that the patient’s vital signs appear abnormal and an
immediate treatment may be required.
The levels of some physiological alarms are predefined before the monitor
leaves the factory and can not be changed by users. While some levels of physiological alarms can
48
be changed by users.
The monitor’s technical alarms are classified into two categories: medium level and low level.
The levels of technical alarms are predefined before the monitor leaves the
factory and can not be changed by users.

6.3 Alarm Indicators

When an alarm occurs, the monitor will indicate it through the following means:
 Alarm tone: According to alarm level, speaker in the monitor gives alarm sound in
different tone.
 Alarm lamp: According to alarm level, alarm lamp on monitor flashes in different
color and speed.
 Alarm message: Alarm messages are displayed on the screen.
 Flashing numeric: The numeric of parameter in alarm flashes.

Caution
The concrete presentation of each alarm prompt is related to the alarm level.

6.3.1 Alarm Tone

Chapter 8 ECG/ RESP

8.1 Introduction
Before mechanical systole, the heart firstly produces electrical excitement, which results in
biological current, and conducts the current to the body surface through tissue and humour. Different
potential changes take place at various parts of the body, thus body-surface potential differences are
formed. Record the changing potential differences to form the dynamic curve, i.e. ECG, also called
body-surface ECG or regular ECG.

Through many electrodes connected with ECG cables, the monitor examines the changes of
body-surface potential caused by the heart of patient, observes the ECG activities, records the ECG
waveform, and calculates the HR. The monitor can achieve 3-lead, 5-lead and 12-lead monitoring,
and has the function of ST-segment monitoring and arrhythmia analysis.

8.2 Safety Information

Warning
It is imperative to only use the ECG electrodes and cables provided by manufacturer or
specified in this manual. Users shall use the electrode which has little polarization voltage and
little contact resistance.
When the electrode polarized voltage is too high, the monitor will indicate the abnormal state
by alarm system.
Before connecting the ECG cables to the monitor, please check if the lead wires and cables
have been worn out or cracked. If so, they should be replaced.
When you are connecting the electrodes or the patient cable, make sure that the connectors
never come into contact with other conductive parts, or with earth. In particular, make sure
that all of the ECG electrodes are attached to the patient, to prevent them from contacting
conductive parts or earth.

Please check the skin where the electrodes are placed, replace the electrodes or relocate the
electrodes in case of skin allergy occurs.
When conducting defibrillation, it is imperative to only use the ECG electrodes and cables
specified by manufacturer.
Do not touch the patient, bed or the monitor during defibrillation.
The monitor is protected against defibrillation effect. When applying defibrillator to the
patient, the monitor will experience transient disorderly waveforms. If the electrodes are used
and placed correctly, the display of the monitor will be restored within 10s. During
defibrillation, the chest leads such as V1~V6 should be removed and such limb electrodes as
RA, LA, RL, LL should be moved to the side of the limbs.
Interference from instruments near the patient and ESU interference can cause problems with
the ECG wave.
The monitor cannot be directly applied to heart and cannot be used for the measurement of
endocardio ECG.

8.3 Monitoring Procedure

8.3.1 Skin Preparation for Electrode Placement

Good electrode-to-skin contact is important for a good ECG signal, as the skin is a poor conductor of
electricity. It is necessary to deal with the skin properly before placing the electrodes. The steps are
shown as follows:
1. Select sites with intact skin, without impairment of any kind.
2. Clip or shave hair from sites as necessary.
3. Gently abrade the skin to remove dead skin cells to improve the conductivity of the electrode site.
4. Wash sites thoroughly with soap and water, leaving no soap residue.
(We do not recommend using ether or pure alcohol, because this dries the skin and increases the
resistance.)
5. Dry skin thoroughly.

8.3.2 Placing Electrode

1. Preparation before electrode placement

1) Skin preparation (refers to Chapter 8.3.1);
2) Check if the buttons on the electrodes are clean and free of damage;
3) Place the electrodes on the body of patient. Before attaching, smear some conducting cream on
the electrodes if the electrodes are not electrolyte self-supplied;
4) Connect the cable leads to the electrodes through the buttons of the electrodes.

Note
For patients who tremble a lot or patients with especially weak ECG signals, it might be
difficult to extract the ECG signals, and it is even more difficult to conduct HR count. For
severely burnt patients, it may be impossible to stick the electrodes on and it may be necessary
to use the special pin-shape electrodes. In case of bad signals, care should be taken to place the
electrodes on the soft portions of the muscle.
Check the irritation caused by each electrode to the skin, and in case of any inflammations or
allergies, the electrodes should be replaced and the user should relocate the electrodes every
24h or at a shorter interval.
When the electrotome operation is performed, the ECG leadwires should be intertwisted as
much as possible. The monitor should be placed far from the operating table. Power wires and
the ECG lead cables should be partitioned and should not be in parallel.

60
2. Electrode Placement
 3-Lead
Take the AHA standard as an example, when conducting 3-lead ECG monitoring, use 3-lead ECG
cable. The three limb-leads of RA, LA and LL as shown in below figure, will be placed on the
relevant locations. This connection can establish the lead of I, II, III.

RA LA

LL

 5-Lead
Take the AHA standard for example, when conducting 7-lead ECG monitoring, use 5-lead ECG
cable. The four limb-leads of RA, LA, RL and LL as shown in below figure, will be placed on the
relevant locations. This connection can establish the lead of I, II, III, aVR, aVL, aVF; according to
actual needs, chest lead V can be placed on any of the locations between V1~V6, respectively
making one lead of V1~V6 established.

RA LA

RL LL

61
 12-Lead
Take the AHA standard as an example, when conducting 12-lead ECG monitoring, use 12-lead ECG
cable, and all the leads are placed on the relevant locations respectively as shown in the below figure.
This kind of connection realizes the establishment of such 12 leads as I, II, III, aVR, aVL, aVF,
V1~V6.

RA LA

RL LL

 Place electrodes for a surgical patient

While placing electrodes for a surgical patient, the type of surgery should be considered, for instance,
as to a chest surgery, the chest lead electrodes can be placed at sides or backside of chest. Moreover,
while using a surgical electrotome, in order to reduce the influence of artifacts to ECG waveform,
the electrodes can be placed at left and right shoulders, close to left and right sides of abdomen; the
chest lead electrodes can be placed at left side of chest midst. Please avoid placing the electrode at
the upper arms, otherwise the ECG waveform will become very small.

Warning
To avoid burning, when the electrotome operation is performed, the electrodes should be
placed near the middle between ESU grounding pad and electrotome and the electrotome
should be applied as far as possible from all other electrodes, a distance of at least 15 cm/6 in is
recommended.
When using the ESU device, avoid placing the electrodes near the ESU grounding pad,
otherwise, grate deal interference will influence the ECG signals. The monitor should be
placed far from the operating table. Power wires and the ECG cables should be partitioned
and should not be in parallel.

The following table shows the ECG electrode label to identify each electrode and its associated color

8.3.3 Connecting ECG Cable

Plug the ECG cable into the ECG connector. An ECG waveform and numeric appears on the monitor
display.

8.3.4 Selecting Leads

Depending on the patient to be monitored, you shall select the proper leads
as required.
1. Select ECG parameter area, enter ECG parameter setup menu, select【Lead Type】.
2. You can select【3 lead】,【5 lead】or【12 lead】.

8.3.5 Checking Paced Status

It is important to set the paced status correctly when you start monitoring ECG.
If the【Paced】status has been set to【Yes】, the icon will be shown on the screen. If the system
detects paced signal, the symbol “︱” will be marked on the ECG wave.
To change the paced status, you can select【Patient】smartkey→【Patient Info】, and set the【Paced】
status in the popped up menu.

Warning
For paced patients, you must set【Paced】to【Yes】. If it is incorrectly set to【No】, the monitor
63
 could mistake pace pulses for regular QRS complexes and fail to alarm during asystole.
Some pace pulses can be difficult to reject. When this happens, the pulses are counted as a
QRS complex, and could result in an incorrect HR and failure to detect cardiac arrest or some
arrhythmias. Keep pacemaker patients under close observation.
For non-paced patients, you must set【Paced】to【No】, otherwise, the system can not detect the
arrhythmia related to Ventricular Premature(including PVCs count), and will not conduct ST
analysis.

8.6 ST Monitoring
The monitor performs ST segment analysis on normal and atrially paced beats and calculates ST
segment elevations and depressions.
ST segment monitoring is only intended for use with adult patients.
The clinical significance of the ST segment analysis should be determined by a physician.

Warning
Some clinical conditions may make it difficult to achieve reliable ST monitoring, for example:
——If you are unable to get a lead that is not noisy;
——If the patient is continuously ventricularly paced;

——If the patient has left bundle branch block;

——If arrhythmias such as atrial fib/flutter are present, which may cause an irregular
baseline;
You should consider switching ST monitoring off if these conditions are present.

8.6.1 Switching ST On and Off

Select【ST Setup】in the ECG setting menu, from the popped up window select【ST Analysis】, it can
be set to【On】or【Off】.
When switching ST analysis on, the system will set【ECG Mode】to【】automatically if
operating on the other ECG mode. At this time, if you select the ECG mode other than【Diag】, the
measurement of ST segment will be severely distortional.

8.6.2 ST Display

ST
numerics

ST segment are displayed on the right of ECG parameter area of screen. The quantity for ST
segments displaying on the screen depends on the current lead type, and it also depends on the
quantity of parameters displaying on the screen. Up to 12 ST segment numerics of 12 leads can be
displayed on the screen.
66
A positive ST value indicates ST segment elevation; a negative value indicates depression.

8.6.3 Setting ST Alarm

The ST alarm limit of each lead can be set in ST analysis setting menu, and in this menu, you can
also set alarm switch, alarm level and alarm print switch.

8.6.4 Adjust ST point

The ST value for each beat complex is the vertical difference between the ISO point and the ST
point, as shown in the figure below. The isoelectric (ISO) point provides the baseline, the ST point is
at the midpoint of the ST segment. The J point is where the QRS complex changes its slope; as it is a
fixed distance away from the ST point, it can be useful to help you position the ST point correctly.

In the ST analysis menu, select【Adjust ST point】, the QRS complex will be displayed on the popped
up window, the two vertical lines indicate the position of ISO point and ST point. Set the R wave
peak as the reference point for ST measurement.
The ST measurement points and ISO point need to be adjusted when you start monitoring, and if the
patient's heart rate or ECG morphology changes significantly.
You can select【ISO】or【ST】and then adjust the point right and left.

Caution
When conducting ST analysis, the system will not consider abnormal QRS complex.

8.8 Respiration Rate (Resp)

Introduction
For the respiratory measurement (Resp), the monitor measures the thoracic impedance between two
ECG electrodes on the patient’s chest. Changes in the impedance due to thoracic movement produce
the Resp waveform on the monitor screen. The monitor counts the waveform cycles to calculate the
respiration rate (RR).

8.7.1 Safety Information

Warning
For the sake of safety, all the leads on the ECG cable must be connected to patient.
When monitoring Resp, the ECG cable with electrotome-proof must not be used.
The measurement of Resp is not applicable for patient with excessive motion, otherwise it may
cause the mistake of Resp alarm.

8.7.2 Monitoring Procedure

1. Connecting ECG Cable

To monitor Resp parameters, it is unnecessary to use other cables and it is only necessary to use the
ECG cable.

2. Placing Resp Electrodes

Skin preparation for electrode placement refers to chapter 8.3.1. It is unnecessary to use other
electrodes for monitoring Resp, but it is very important to place the electrodes. The Resp signal is
always measured between two of the ECG electrodes. If you are using standard ECG electrode
placement, Resp is measured between the RA and LL electrodes or between the RA and LA
electrodes.

Caution
In order to get the best Resp waveforms, when using RA and LA electrodes for measuring
Resp, it is advised to place them horizontally; when using RA and LL electrodes, it is advised
to place them cornerways.

 Optimizing Lead Placement for Resp

If you want to measure Resp and you are already measuring ECG, you may need to optimize
placement of the two electrodes between which Resp will be measured for some patients.
Repositioning ECG electrodes from standard positions, results in changes in the ECG waveform and
may influence ST monitoring.

71
  Cardiac Overlay
Cardiac activity that affects the Resp waveform is called cardiac overlay. It happens when the Resp
electrodes pick up impedance changes caused by the rhythmic blood flow. Correct electrode
placement can help to reduce cardiac overlay: avoid the liver area and the ventricles of the heart in
the line between the Resp electrodes. This is particularly important for neonates

 Lateral Chest Expansion

Some patients, especially neonates, expand their chests laterally. In these cases it is best to place the
two Resp electrodes in the right midaxillary and left lateral chest areas at the patient’s maximum
point of breathing movement to optimize the Resp wave.

 Abdominal Breathing
Some patients with restricted chest movement breathe mainly abdominally. In these cases, you may
need to place the left leg electrode on the left abdomen at the point of maximum abdominal
expansion to optimize the Resp wave.

Chapter 9 SpO2 Monitoring

9.1 Introduction
The measurement of oxygen saturation of arterial blood (also known as pulse oxygen saturation,
usually shortened as SpO2) adopts the principles of light spectra and volume tracing. The LED emits
lights with two specific wavelengths, which are selectively absorbed by oxygenated hemoglobin and
deoxyhemoglobin. The optical receptor measures the changes in the light intensity after the light
passes the capillary network and estimates the ratio of oxygenated hemoglobin and the total
hemoglobin.

oxygenated hemoglobin
SpO2 % = 100%
oxyhemoglobin + deoxyhemoglobin
73
The SpO2 sensor measurement wavelengths are nominally 660nm for the Red LED and 940nm for
infrared LED

9.2 Safety Information

Warning
Use only SpO2 sensors specified in this manual. Follow the SpO2 sensor’s instructions for use
and adhere to all warnings and cautions.
When a trend toward patient deoxygenation is indicated, blood samples should be analyzed by
a laboratory co-oximeter to completely understand the patient’s conditions.
Do not use the monitor and the SpO2 sensor during magnetic resonance imaging (MRI).
Induced current could cause burns.
Prolonged continuous monitoring may increase the risk of unexpected changes in skin
characteristics, such as irritation, reddening, blistering or burns. Inspect the sensor site every
two hours and move the sensor if the skin quality changes. For neonates, or patients with poor
peripheral blood circulation or sensitive skin, inspect the sensor site more frequently.

Warning
Check the SpO2 sensor and its package for any sign of damage before use. Do not use the
sensor if any damage is detected.
Before use, the operator must ensure the compatibilityies of the monitor, SpO2 sensor and
extension cables; otherwise, this may lead to the burning of patients; do not use damaged
sensor or extension cable. Do not soak the sensor into water or make it wet, otherwise it may be
damaged.
When disposing the disposable SpO2 probe or useless SpO2 probe, please observe all local,
state, and federal regulations that relate to the disposal of this products or similar products.
Pulse rate measurement is based on the optical detection of a peripheral flow pulse and
therefore may not detect certain arrhythmias. The pulse oximeter should not be used as a
replacement or substitute for ECG based arrhythmia analysis.

Caution
In case it is necessary to add a clip to fix the fingertip sensor, the cable instead of the sensor
itself should be clipped. Please note that the cable of sensor should not be pulled with force.

Note
The pleth wave is not equal to the intensity of PR signal.
The monitor does not provide automatic self-examination alarm signal and the operator has to
use SpO2 simulator for self-examination.

9.3 Monitoring Procedure

1. Selecting SpO2 Sensor
Depending on the patient category, weight and application site, you can select the SpO2 sensor as
required.

2. Connecting SpO2 Sensor

74
Plug the SpO2 sensor cable into the SpO2 connector on the measurement module.

3. Applying SpO2 Sensor

Clean the application site, such as colored nail polish, and apply the sensor
to the patient.

Warning
Do not use the SpO2 sensor on a limb where the NIBP cuff is applied. This may result in
inaccurate SpO2 reading due to blocked blood flow during cuff inflation.
Do not conduct SpO2 measurement on the finger smeared with nail polish, otherwise
unreliable measurement results might be produced.
When using finger sensor, make sure the nail faces to the light window.

9.5 Setting SpO2

9.5.1 Setting SpO2 Parameter

Select SpO2 parameter area to enter SpO2 parameter setting.

 Setting NIBP measurement on the same limb

When NIBP and SpO2 are simultaneously measured to the same limb of patient, the operator shall
enter the SpO2 parameter setting menu and set 【NIBP Same Side】to【On】in order to ensure that
the SpO2 alarm status will keep constant during the NIBP measurement until the completion of
NIBP measurement. If【NIBP Same Side】is set to【Off】, the low perfusion will result in the SpO2
measurement inaccuracy during the NIBP measurement and trigger the physiological alarm of SpO2.

 Setting Pulse Volume

Select【Pulse Volume】in the SpO2 setting menu to change the QRS volume. The volume can be set
to a value between 1 and 3, and also can be silenced.

 Setting Average Time

The SpO2 reading shown on the monitor is the average of data collected within a specific time. The
shorter the averaging time is, the quicker the monitor responds to the change in the patient’s oxygen
saturation level. Contrarily, the longer the averaging time is, the slower the monitor responds to the
change in the patient’s oxygen saturation level, but the measurement accuracy will be improved.
When a critical patient is monitored, selecting shorter averaging time will help understanding the
patient’s state.
You can select【Average Time】in the SpO2 setting menu, and select a proper time as required.

 Setting PR Displaying
Select【PR Display】in the SpO2 parameter setting menu, you can select【On】or【Off】to set if PR
is displayed on the screen. The option of 【PR Display】can be also set in ART setting menu.

SpO2 sensor. The following factors may influence the accuracy of measurements:
——Incorrect sensor application or use;
——Significant levels of dysfunctional hemoglobins.(such as carboxyhemoglobin or
methemoglobin);
——Intravascular dys such as indocyanine green or methylene blue;
——Exposure to excessive illumination, such as surgical lamps (especially
ones with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, or direct
sunlight (exposure to excessive illumination can be corrected by covering the sensor with a dark or
opaque material)
——Excessive patient movement;
——Venous pulsations;
——Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line.
——Low perfusion;
——Electromagnetic interference, such as MRI device;
——Electrosurgical units.
The monitor can be used during defibrillation, but the readings may be
inaccurate for a short time
Loss of pulse signal can occur in any of the following situation:
——The sensor is too tight;
——There is excessive illumination from light sources such as a surgical lamp, a brilirubin lamp, or
sunlight;
——A blood pressure cuff is inflated on the same extremity as the one with a SpO2 sensor attached;
——The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia;
——There is arterial occlusion proximal to the sensor.
——The patient is in cardiac arrest or is in shock.

Chapter 10 TEMP Monitoring

10.1 Introduction
The monitor measures Temperature with Temperature sensors.
77
The monitor has maximum eight channels for Temp measurement option, and can display the
temperature of eight channels and temperature difference (TD) at the same time.

10.2 Safety Information

Warning
Disposable Temp probes must not be re-sterilized or reused.
The calibration of temperature measurement is necessary for every two years (or as frequently
as dictated by your Hospital Procedures Policy). When you need calibrate the temperature,
please contact the manufacturer.
Should the Temp probe become damaged beyond repair, or for some reason its useful life is
considered to be at an end, please observe all local, state, and federal regulations that relate to
the disposal of this products or similar products.

Caution
The self-test of the temperature measurement is performed automatically termly during the
monitoring. The test procedure lasts about 1s and does not affect the normal measurement of
the Temp monitoring.
The Temp sensors and cables should be handled with care. When not in use, the sensor and the
cable should be rounded into loose ring shape.

Note
If Temp to be measured beyond probe’s measuring range, over measuring range alarm will be
displayed on the screen. Check if probe is on the corresponding patient body site, or change it
to other site on the patient.
If “Temp self-check error” is displayed on the screen, it is possibly that something is wrong
with the temperature module, the operator should stop using the module and contact the
manufacturer.

Chapter 11 NIBP Monitoring

11.1 Introduction
The monitor uses the oscillometric method for measuring NIBP. It is applicable for adult, pediatric
and neonatal patients. The method of oscillometric indirectly estimates the systolic and diastolic
pressures within the blood vessels by measuring the change of the pressure within blood pressure
cuff along with the volume of the arteries and calculates the average pressure.
The NIBP measurement is suitable for use in the presence of electrosurgery and during the discharge
of a cardiac defibrillator according to IEC 60601-2-30:1999/EN 60601-2-30:2000.
A physician must determine the clinical significance of the NIBP measurement.

11.2 Safety Information

Warning
Check the patient category before monitoring. Incorrect settings may result in some risk for
patient safety. Higher adult setting is not suitable for pediatric and neonatal patients.
Do not measure NIBP on patients with sickle-cell disease or any condition where skin damage
has occurred or is expected.
Use clinical judgement to decide whether to perform frequent Auto BP measurements on
patients with severe blood clotting disorders because of the risk of hematoma in the limb fitted
with the cuff.
Use clinical judgement to decide whether to perform Auto BP measurement on the patients of
thrombasthemia.
Do not use the NIBP cuff on a limb with an intravenous infusion or arterial catheter in place.
This could cause tissue damage around the catheter when the infusion is slowed or blocked
during cuff inflation.
If you doubt the NIBP measurements, check the patient’s vital signs by other device, and then
check the monitor.

11.3 Measurement Limitations

NIBP measurements are impossible with heart rate extremes of less than 40 bpm or greater than 240
bpm, or if the patient is on a heart-lung machine.
The measurement may be inaccurate or impossible:
——with excessive and continuous patient movement such as shivering or convulsions;
——if a regular arterial pressure pulse is hard to detect;
——with cardiac arrhythmias;
——with rapid blood pressure changes;
——with severe shock or hypothermia that reduces blood flow to the peripheries;
——on an edematous extremity.

80
11.4 Measurement Mode
There are three modes of measuring NIBP:
 Manual: measurement on demand.
 Auto: continually repeated measurements in the set interval.
 STAT: rapid series of measurements over a five minutes period, then the
monitor returns to the previous mode. Use only on supervised patients.

11.5 Monitoring Procedure

11.5.1 Preparing to Measure NIBP

1. Check the patient category, if you want to change the patient category,
select【Main menu】smartkey→【Patient】→【Admit Patient】and select the patient category as
required.
2. Select the appropriate cuff according to patient category.
——Check the limb circumference of patient.
——Select the appropriate cuff (The applicable limb circumference for cuff is marked on the cuff).
The width of the cuff should be about 40% of the limb circumference (50% for neonate) or 2/3 of the
upper arm’s length. The inflatable part of the cuff should be long enough to encircle 50%~80% of
the limb.

Note
The accuracy of measurement of BP depends on the suitability of the cuff.

3. Confirm the cuff has been entirely deflated.

4. Plug the air pipe plug of cuff into the connector (NIBP) of monitor until the plug and socket
contact well. (Attention: you shall nip the part of air pipe plug of cuff close to socket with fingers
before pulling it out.)
5. Tie the cuff to the upper arm or thigh of the patient.
Ensure the mark “Φ” on the cuff shall lie above artery while the air pipe shall be under the cuff,
ensuring the air pipe outside the cuff does not knot and the white line on the cuff shall be within the
range “ ”, otherwise the cuff shall be replaced.
The monitor is applicable for standard neonatal cuff, pediatric cuff and adult cuff. (including arm
cuff and thigh cuff).

Note
While measuring blood pressure, the patient must keep calm without any talk.
The cuff tied on the limb shall be on the same level as the patient’s heart so as to avoid the
reading error resulting from the hydrostatics effect of the blood flow between the heart and
cuff. If the cuff position is higher than heart level, the BP reading will be lower, the measured
result shall be added 0.75mmHg (0.1kPa) for each centimeter higher; in case the cuff position
is lower than heart level, the BP reading will be higher, the measured result shall be deducted
0.75mmHg (0.1kPa) for each centimeter lower.

6. Connect the cuff with the air-inflating pipe and ensure the pipe connecting cuff is not knotted or
tangled while placing pipe naturally without any press or force.

restores to the initial value. In case the blood pressure pump doesn’t work as normal but without any
prompt, the blood pressure pump can be checked by reset, thus the blood pressure pump in abnormal
condition due to unexpected reason will automatically restore.

11.8 NIBP Maintenance

The maintenance and calibration of NIBP measurement is necessary for every two years. If you need
to maintain NIBP, please contact the professional service personnel. More details about NIBP
maintenance, please refer to Service Manual.

Chapter 12 Freezing

While monitoring a patient, you can freeze the waveform on the screen, and then you can carefully
survey the condition of the patient during this time interval through reviewing the frozen waveform.
Meanwhile, you can output the frozen waveform by recorder or printer.

12.1 Freezing Waveform

Under the non-freezing condition, select【Wave Freeze】smartkey on lower monitor screen or press
the button on the front monitor panel, then you can get the waveform enter freezing condition.
All waveform will be frozen without any more refreshing or roll. The data displayed in the
parameter area will normally be refreshed.
The freezing condition will not influence the following functions:
—— Display and refreshing of dynamic short-time graphic trends.
——Display and refreshing of respiration oxygen chart.
——Display and refreshing of the monitoring screen of other sickbeds.

12.2 Reviewing Waveform

Under the freezing condition, you can browse frozen waveform for careful survey through the
following methods:
Select【Turn L/R】 in the freezing setting, then by turning the trim knob right or left to make the
waveform move right or left accordingly. Meanwhile, one down arrow and time scale will be
showed at the lower right corner of each waveform. The initial freezing time is recorded as【0s】,
which will gradually changes into【-1s】【-2s】
, 【-3s】
, … along with the waveform moving rightwards.

12.3 Releasing Freezing

Under freezing condition, you can select the【Back】smartkey on lower monitor screen, or press the
button on the front monitor panel to release the freezing condition.

Chapter 13 Other Functions

13.1 Nurse Call

Nurse Call is a function that the monitor will send signal to call nurse when the alarm conditions
destined are occurred.
The monitor has a nurse call output connector, connect the connector to the nurse call system of the
hospital by the nurse-call cable provided along with the monitor, the nurse call function can be
realized.
The nurse call function is valid when the following conditions are concurrent:
——The nurse call function is open.
——An alarm condition destined is occurred.
——The monitor is not in the state of alarm paused or system silence.
The setting way of nurse call, please refer to Service Manual.

Warning
The nurse call function should not be used as the primary patient alarm inform source. It is
necessary for combining the auditory and visual alarm signal and the patient clinical feature
and symptom as the primary information to medical and nursing staff about the physiological
condition of the patient.

13.2 Analog Signal Output

The monitor has an auxiliary output port that can provide “analog signal output”. Connect the
monitor to an equipment such as an oscillograph, and then do some associated setup, after that you
can output the analog signal to the oscillograph through the port.
The setting way of analog signal output, please refer to Service Manual.

13.3 Event Mark

In the process of monitoring patient, some events can influence the patient and lead to change of
some monitored waveform or parameter. For better analyzing these influences, you can make
manual marks for some special events.
Before making mark, you need to define the event A, B, C and D. For instance, the event A is
defined as injecting medicine, so that you can mark the event while injecting patient with following
steps:
 Select the【Mark】smartkey and then select【Event A】to mark the event.
While reviewing graphic trends, tabular trends or waveform, corresponding mark will be displayed

86
at the occurrence time of the marked event, such as A, B, C , D and so on.
