Precautions for Safe Operation of Medical Telemetry (When using
HLX-501)
CAUTION
To operate the device correctly, read the following precautions carefully.
zThe medical institution (hereinafter referred to as the “Institution”) must
decide the telemetry installation plan to prevent interference and
interference between transmitters (telemetry based on destination country’s
radio law). When telemetry has already been installed and been used, radio
format, frequency, and antenna power are required to be examined to
prevent interference.
zWhen using telemetry which requires zone location, the Institution is to set
up the zones as an operation unit for each transmitter to prevent electronic
interference between telemetry throughout the medical institution.
zWhen using telemetry which requires zone location, display and identify
each prepared zone in the equipment.
zWhen laying receiver antenna for each transmitter, the Institution has to
examine the installation so that electronic interference does not occur.
zBased on the above examination result, the Institution should place each
receiver antenna as required.
In managing, make sure to follow the precautions below.
zThe institution appoints a person to manage the wireless channels for the
whole medical institution. And when using telemetry which requires zone
location, the Institution should nominate a person to manage the wireless
channels in each zone (a “Zone Manager”). However, when using such
telemetry in a local medical institution, one person can perform both
functions.
zSelect a telemetry manager who understands the characteristics and
functionality of telemetry systems, and is skilled in operating telemetry.
zWhen installing telemetry, the Overall Manager and the Zone Manager
have to understand the precautions for use of the telemetry in advance.
zThe Overall Manager takes responsibility of wireless channel management
and transmitter storage for the whole medical institution by giving proper
instruction.
zThe Overall Manager creates a management log, list of wireless channels,
management status for the whole medical institution (hereinafter referred to
as the “management log”. When changing a wireless channel, register it
in the log and give proper instructions to the zone manager or to the user.
zThe Zone Manager assumes responsibility for managing the wireless
channels, storing, and managing telemetry.
zThe Zone Manager assigns the transmitter to the user, and provides
enough education for use inside the zone.
zThe telemetry user verifies operation of the transmitter/receiver before use.
zThe telemetry user, if using the telemetry in a zone location, follows the
instructions of the Zone Manager for the zone and gives instructions to the
patient if required.
zWhen interference or breakdown occurs in telemetry communication, the
user is required to inform the zone manager and the overall manager of the
problems. The zone manager and overall manager are to deal with the
problem properly and/or contact their nearest Fukuda Denshi
representative for service.

Precautions about Pacemaker
WARNING
zMinute ventilation rate-adaptive implantable pacemakers can
occasionally interact with certain cardiac monitoring and diagnostic
equipment, causing the pacemakers to pace at their maximum
programmed rate. The cardiac monitoring and diagnostic equipment
may possibly send wrong information.
If such event occurs, please disconnect the cardiac monitoring and
diagnostic equipment, or follow the procedures described in the
operation manual of the pacemaker.
For more details, contact FUKUDA DENSHI personnel, your institution’s
professionals, or your pacemaker distributors.
Reference “Minute Ventilation Rate-Adaptive Pacemakers”
FDA alerts health professionals that minute ventilation
rate-adaptive implantable pacemakers can occasionally interact
with certain cardiac monitoring and diagnostic equipment, causing
pacemakers to pace at their maximum programmed rate.
[October 14, 1998 (Letter: www.fda.gov/cdrh/safety.html) – FDA]
Non-Explosion Proof
DANGER
Never operate the equipment in the presence of flammable anesthetics,
high concentration of oxygen, or inside hyperbaric chamber. Also, do not
operate the equipment in an environment in which there is a risk of
explosion.
Explosion or fire may result.
Defibrillation Safety
WARNING
zWhen defibrillating, keep away from the electrodes or medicament
applied to the patient chest. If this is not possible, remove the electrodes
or medicament before defibrillating.
If the defibrillator paddles are directly in contact with the electrodes or
medicament, an electrical shock may result from the discharged energy.
zWhen defibrillating, make sure that the electrodes, sensor cables, or
relay cables are firmly connected to the device.
Contacting the metal part of the disconnected cable may result in
electrical shock from the discharged energy.
zWhen defibrillating, do not touch the patient and the metal part of the
device or cables. Electric shock may result from the discharged energy.
x

Electrosurgery Safety
WARNING
The monitoring system contains protection against interference generated
by electrosurgical instruments. However, operating conditions, surgery site
with respect to the location of ECG electrodes, or the type of instrument
used, may cause noise on the ECG. The noise is generated at the tip of the
electrical knife and is difficult to completely eliminate because of the
frequency components of the ECG. To reduce electrosurgical interference,
take the following precautions:
Location
Locate the electrosurgical unit as far as possible from this unit and the
patient cable. This will help reduce interference on the ECG through the
monitor or cables.
Power Supply
Connect the electrosurgical unit to a power supply that is different from
that of the monitor. This will help prevent interference through the power
cable.
Electrode Placement
The amount of interference is considerably different depending on the
electrode position and surgery site. Place the ECG electrodes as far
away as possible from the surgery site. Do not place electrodes in the
path between the surgery site and the ground plate. If the electrodes
are placed in this path, the amount of interference will be quite large.
Position (+) and (–) electrodes as close as possible to each other.
Ground Plate
When using electrosurgical instruments, make sure the contact between
the patient and the ground plate is secure. If the connection is
incomplete, the patient may suffer a burn at the electrode site.
Precautions about Magnetic Resonance Imaging
WARNING
zDo not operate this equipment in magnetic resonance imaging (MRI)
environments.
zWhen conducting MRI test, remove the electrodes and sensors
connected to the patient (test subject).
The local heating caused by the induced electromotive force may cause
burn injury to the patient (subject). For details, refer to the operation
manual for the MRI testing device.
xi

Precautions about Connections to Peripheral Devices
For safety and good performance of this equipment, connection of other manufacturers’ equipment
to the monitor is not authorized, unless the connection is explicitly approved by Fukuda Denshi. It
is the user’s responsibility to contact Fukuda Denshi to determine the compatibility and warranty
status of any connection made to another manufacturer’s equipment.
WARNING
For the connector with mark, only the peripheral devices specified by
Fukuda Denshi should be connected with the given procedure. Use of an
unspecified device may cause electric shock to the patient and/or operator
due to excessive leakage current.
CAUTION
All the peripheral device connectors on the DS-8500 system are isolated
from the power supply, but the peripheral devices are not isolated. To
prevent danger of electric shock, always position the peripheral devices
away from the patient.
When connecting peripheral devices to DS-8500 system, it is the user’s responsibility to verify that
the overall system complies with IEC 60601-1-1, “Collateral Standard: Safety Requirements for
Medical Electrical Systems”.
Precautions about the Fuse
DANGER If the fuse blows, do not continue using it as internal damage to the
equipment may be considered.
Accessories and Optional Accessories
WARNING
Use only the cables specified by Fukuda Denshi.
Use of other cables may result in increase in emission (unnecessary
generation of electromagnetic energy from this unit) or decrease in
immunity (resistance characteristics to electromagnetic interference
generating from other device).
xii

Precautions about the DS-8500 System
DANGER Be cautious when connecting to other device.
Danger such as electric shock may result to the patient and operator.
WARNING
zDo not connect a unit or cable not authorized by Fukuda Denshi to any I/O
connector. If done so by mistake, the DS-8500 system cannot deliver its
maximum performance and the connected units may be damaged, resulting
in a safety hazard.
zIf the DS-8500 system is used under an environment not fulfilling the
specified condition, not only that the equipment cannot deliver its maximum
performance, the equipment may be damaged and safety cannot be
ensured.
zUse only the accompanying 3-way AC power cable. Use of other cables
may result in electric shock to the patient and the operator.
zThe power cable must be connected to hospital grade outlet.
zWhen using multiple ME equipment simultaneously, perform equipotential
grounding to prevent potential difference between the equipment. Even a
small potential difference may result in electric shock to the patient and the
operator.
zThe patient classification selection influences the precision of the QRS
detection and NIBP measurement. Make sure the correct selection is
made.
zThe pacemaker use selection influences the precision of the QRS detection
and arrhythmia analysis. Make sure the correct selection is made.
zIf the QRS pace pulse mask function is set to OFF , 10ms or 20ms ,
a decrease in heart rate may not generate HR or ASYSTOLE alarms due to
erroneously detected QRS. Set this function to OFF , 10ms or
20ms only if you are sure that pacing failure will not occur, or when the
patient can be constantly monitored.
zWhen measuring the SpO2of patient with high fever or peripheral
circulatory insufficiency, check the sensor attachment periodically and
change the attachment site. The temperature of attachment site will rise 2
to 3°C due to the sensor heat which may result in burn injury.
zFor the following case, accurate measurement may not be possible.
yPatient with excessive abnormal hemoglobin (HbCO, MetHb)
yPatient with the pigment injected to the blood
yPatient receiving CPR treatment
yWhen a sensor is applied to a limb with NIBP cuff, arterial catheter, or
intracatheter
yWhen measuring at site with venous pulse
yPatient with body motion
yPatient with small pulse
zBefore the measurement, make sure the patient classification ( Adult /
Child / Neonate ) is properly selected. Otherwise, correct
measurement cannot be performed, and congestion or other injury may
result.
zUse the specified sampling tube and nasal prong manufactured by Oridion.
zFor CO2concentration measurement, always consider the circumference of
the intubation tube when using the airway adapter. If inappropriate airway
adapter is used for a patient with low ventilation, CO2may mix in to the
inspired air resulting in incorrect measurement, or apnea detection may
become difficult.
zWhen measuring CO2concentration of a patient treated with
mouth-to-mouth resuscitation, Jackson-Rees circuit, Mapleson D circuit of
which CO2gas may mix in, the value may be displayed lower than the
actual value.
xiii

WARNING
zWhen the system alarm is suspended, all the alarm will be suspended even
if the parameter alarm is set to ON. Also, the alarm event will not be stored
as recall.
zIf the upper/lower alarm limit of the parameter is set to OFF, or arrhythmia
alarm is set to OFF, alarm will not function even if the system alarm is set
to ON. Pay attention when setting them OFF.
zObjective and constant arrhythmia detection is possible through the fixed
algorithm incorporated in this monitor. However, excessive waveform
morphology change, motion artifact, or the inability to determine the
waveform pattern may cause an error, or fail to make adequate detection.
Therefore, physicians should make final decisions using manual recording,
alarm recording and recall waveform for evaluation.
zThe HR/PR alarm will not be generated unless the parameter key
corresponded to the selected HR/PR source is displayed. Make sure to
display the parameter key for the HR/PR source.
zThe RR/APNEA alarm will not be generated unless the parameter key
corresponded to the selected RR/APNEA source is displayed. Make sure to
display the parameter key for the RR/APNEA source.
zWhen selecting Silence or Time Disp. Only for the night mode, pay
attention not to miss any important alarm by simultaneously monitoring the
bed on other monitors such as central monitor.
zWhen lifting this device, hold the bottom part of the main unit and the
display unit.
zWhen attaching the display unit to the DSC main unit, place the display unit
facing down and slowly attach the main unit using the guide on the side of
the display unit. Then, secure it with the specified screws.
zAbout the Trolley
yWhen integrating and mounting a display unit + a main unit + an
exclusive stand to a trolley, make sure that they are fixed using the
screws (x4). Otherwise, the equipment may fall from the trolley, resulting
in injury to the operator or damage to the equipment.
yUse the trolley only with the equipment specified by Fukuda Denshi.
Otherwise, the monitor and trolley may fall down, resulting in injury or
damage to the monitor.
yMake sure to lock both casters when using or storing the trolley.
The trolley may move or fall down, resulting in injury or damage to the
monitor.
yDo not use or store the trolley where it will be subject to inclination of 10
degrees or more. The trolley or equipment may fall resulting in injury or
damage to the equipment.
xiv

CAUTION
zSystems
yUse only the accessories specified for this device. Otherwise, proper
function cannot be executed.
yDo not use the touch panel with the film attached. Malfunction of the
touch panel or damage may result.
yDue 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.
yFor quality improvement, specifications are subject to change without
prior notice.
yThe display panel utilizes exclusive fluorescent light for the backlight.
Since this fluorescent light deteriorates by the life cycle, the display may
become dark, scintillate, or may not light by the long term use. In such
case, contact your nearest service representative and replace the LCD
panel.
yThis equipment is intended to be used for only one patient.
yThe installation of this equipment and attaching the option unit should be
performed by a person who is well acquainted with this equipment.
yIf it is not used for a long period, make sure to turn OFF the power of the
main unit.
zECG Monitoring
yThe indication for continuous use of the electrode is about one day.
yReplace the electrode if the skin contact gets loose due to perspiring,
etc.
yWhen an electrode is attached at the same location for a long time, some
patients may develop a skin irritation. Check the patient’s skin condition
periodically and change the electrode site as required.
yFor 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.
yThe arrhythmia detection level is related with the displayed waveform
size. Set a proper waveform size for monitoring.
When the waveform size is ×1/4, ×1/2, or ×1, the detection threshold is
250µV. When the waveform size is ×2 or ×4, the detection threshold is
150µV.
yThe QRS detection leads, arrhythmia detection leads, monitoring leads
on the central monitor, recording leads are fixed as ECG1 and ECG2.
Especially for arrhythmia detection, set the most appropriate leads with
high QRS for ECG1 and ECG2.
yAutomatic size/position of the ECG is effective only at the time the
AUTO key is pressed. This does not continually adjust size and
position.
yThe ESIS mode can largely reduce the artifact such as electrosurgery
noise and EMG, but it may also reduce the QRS amplitude. Using the
ESIS mode may erroneously detect the pacemaker spike. The ESIS
mode should be selected only during electrosurgery.
yThere are some cases when pacemaker pulse can not 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 pacemaker pulse
detection.
yIf 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.
yWhen spontaneous QRS and pacemaker pulse overlap (ex. fusion beat,
etc.), QRS detection cannot be performed properly. In this case, the
heart rate is degraded.
xv

CAUTION
yWhen continuously detecting AC noise artifact as pacemaker pulses,
QRS detection stops and heart rate is extremely degraded. Also
arrhythmia cannot be detected.
zRespiration Monitoring
yWhen a defibrillator is used during respiration monitoring, a large offset
voltage will be placed on the ECG electrodes, which may cause
interruption of monitoring for a few seconds.
zSpO2Monitoring
yIf the nail is rough, dirty, or manicured, accurate measurement will not be
possible. Select a different finger or clean the nail before attaching the
sensor.
yIf irritation such as skin reddening or rash appears with the sensor use,
change the attachment site or stop using the sensor.
yWhen fixing the sensor with tape, do not wind the tape too tight. At the
same time, check the blood flow constantly so that congestion is not
generated at the peripheral.
yEven a short duration of attachment may inhibit the blood flow and
generate compression necrosis and burn injury.
yChange the sensor attachment site constantly (every 4 hours). As the
temperature of the sensor attachment site normally rises 2 to 3°C
yAs skin for neonate / low birth weight infant is immature, change the
sensor attachment site more frequently depending on the condition.
yDirect sunlight to the sensor area can cause a measurement error.
Place a black or dark cloth over the sensor.
yWhen not performing measurement, unplug the relay cable and sensor
from the SpO2connector. Otherwise, the measurement data may be
erroneously displayed by the ambient light.
yThe DS-100A is intended for use on finger of adults weighing over 40 kg
(approximate). Do not use them on children or neonates. Also do not
apply them on the thumb or foot.
yThe light-emitting part of the sensor should be over the root of the
fingernail. Do not insert the finger too far into the sensor as it may hurt the
patient.
yMeasuring on a limb with NIBP cuff, arterial catheter, or intracatheter may
result in incorrect measurement.
zNIBP Monitoring
yPay attention when measuring the NIBP of patient with bleeding disorders
or hyper coagulation. The cuff inflation may cause petechia or circulatory
failure by the blood clot.
yFor the following situation, measurements will be terminated.
When the measurement time has exceeded 160 seconds for adult and
child, 60 seconds for neonate.
When the inflation value has exceeded 300mmHg for adult, 210mmHg for
child, 150mmHg for neonate.
yIf used with the incorrect patient classification, it will not only cause
erroneous measurement, but the inflating level for the adult may be
applied to child or neonate causing dangerous situation to the patient.
yThe 1-minute interval measurement will always start from 00 second.
Pressing the 1min start key will start the measurement from the next 00
second.
yThe alarm function will be ineffective for the BP value measured by Quick
SYS regardless of the ON/OFF selection of NIBP alarm.
yIf the mean display is set to OFF, the mean BP will not be generated.
Also the mean BP will not be displayed inside the tabular trend or the
NIBP list function if the display is set to OFF.
zBP Monitoring
yWhen the main power is turned ON, the BP value will not be displayed
until zero balance is performed. However, if the power is turned ON within
5 minutes after the power is turned OFF, the previous zero balance
information will be maintained, and BP value will be displayed.
