v
Precautions about the Pacemaker
WARNING
Minute 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]
ECG meter may continue to count the pacemaker rate during
occurrences of cardiac arrest or arrhythmias. Do not rely entirely upon
the ECG meter alarms. Keep pacemaker patients under close
surveillance. Check this manual for disclosure of the pacemaker pulse
rejection capability of this instrument.
Precautions about the LX-7230
WARNING
Do not connect cables not authorized by Fukuda Denshi to any I/O
connector. If done so by mistake, the LX-7230 cannot deliver its
maximum performance and may be damaged, resulting in a safety
hazard.
Do not use this device with multiple patients simultaneously.
CAUTION
Do not pick up and/or swing the LX-7230 pulling/grabbing the probe
(sensor) or cord part. The cable could break or get disconnected from the
LX-7230. And it may hit people or damage other equipment around.
vi
Precautions about Waterproof
CAUTION

Do not use the LX-7230 wet. Always wipe the LX-7230 with a soft cloth
and dry it thoroughly before use.
probes (sensors/relay cables) are not waterproof.
2
Precautions about ECG
CAUTION
When removing electrodes from the patient, remove them carefully and
slowly. Do not apply excessive force to remove them. Otherwise, it may
damage the skin.
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), electrode placement, or lead method which
causes the pacemaker pulse amplitude to decrease and disables
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. In this case,
check the condition of the electrodes and ECG lead cable to resolve the
cause or turn off the pacemaker detection setting on the receiving
monitor.
vii
Precautions about SpO
2
WARNING
During SpO2 monitoring, always use the probe (sensor)/relay cable
specified by Fukuda Denshi. If any other probe (sensor)/relay cable is
used, a high temperature rise of the probe (sensor) may place the
patient in danger of burns in the worst case.
When the SpO2 probe (sensor) is in a connector-off condition, the SpO
alarm will not be generated on the receiving monitor. Make sure that the
probe (sensor)/ relay cable is securely connected. If the SpO
SpO
2
waveform/numeric data is not displayed, check the patient’s condition
and pay attention not to miss the connector-off condition.
When measuring the SpO2 of a patient with high fever or peripheral
circulatory insufficiency, check the probe (sensor) attachment
periodically and change the attachment site. The temperature of the
attachment site will rise 2 to 3C due to the sensor heat which may
result in compression necrosis and burn injury.
Even a short duration of attachment may inhibit the blood flow and
generate compression necrosis and burn injury.
When securing the probe (sensor) with tape, do not apply the tape too
tight. At the same time, check the blood flow constantly so that
congestion is not generated at the peripheral. When removing the tape,
remove it slowly with care not to damage the patient’s skin.
CAUTION
For the following case, accurate measurement may not be possible.
Patient with excessive abnormal hemoglobin (COHb, MetHb)
Patient with the pigment injected to the blood
Patient receiving CPR treatment
Placement of SpO
arterial catheter, or intravascular line
When measuring at placement position with venous pulse

will not generate any alarms. This situation may miss sudden change in
the patient's condition and may cause a serious accident. Under
unstable radio wave signals, check the patient status consistently under
this situation. To get stable radio wave signals, make sure to have a
proper telemetry installation.
CAUTION
For installation, make sure the following.
The medical institution (hereinafter referred to as the “Institution”) must
decide the telemetry installation plan for the medical department in order
to prevent interference and interference between transmitters (telemetry
x
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.
When 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 Institution.
When using telemetry, which requires zone location, display and identify
each prepared zone in the equipment.When laying receiver antenna for
each transmitter, the Institution has to examine the installation so that
electronic interference does not occur.
Based on the above examination result, the Institution should install each
receiver antenna as required.
For management, make sure to follow the precautions below.
The Institution should appoint a person (hereinafter referred to as the
“Overall Manager”) to manage the wireless channels for the whole
Institution.
And when using telemetry, which requires zone location, the Institution
should nominate a person (hereinafter referred to as the “Zone Manager”)
to manage the wireless channels in each zone. However, when using such
telemetry in a local Institution, one person can perform both functions.
The Overall Manager and Zone Manager must be selected from people
who understand the characteristics and functionality of telemetry systems,
and are skilled in operating telemetry.
When installing telemetry, the Overall Manager and the Zone Manager
have to understand the precautions for use of telemetry in advance.
The Overall Manager is responsible for maintenance of wireless channel
and storage and maintenance of telemeter in the overall medical facilities
to give proper instructions to the Zone Manager when using telemetry
needing zone alignment, and to the telemetry user when using telemetry
not-needing zone alignment.
The Overall Manager should create a management log (hereinafter
referred to as the “log”), which contains a list of the management status of
the wireless channels for the whole Institution. When changing a wireless
channel, register it in the log and give proper instructions to the Zone
Manager or to the user.
The Zone Manager assumes responsibility for managing the wireless
channels, storing, and managing telemetry.
The Zone Manager assigns the transmitter to the user, and provides
enough education for use inside the zone.
The telemetry user verifies operation of the transmitter/receiver before
use.
The 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.
When 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.

ECG lead selection is available using the two buttons (Enter and
front panel. (In case of using a 3-electrode lead cable or a 5-electrode chest
lead cable)
The LX-7230 can also function as a transmitter to measure only the
ECG/Respiration without SpO2 or to measure only the SpO2 without
ECG/Respiration.
Before using the LX-7230, read also the operation manual of the patient
monitor at the receiving side thoroughly.
There are two types of transmitters depending on the SpO2 Module, which is
built-in as below.

3. Preparation
1) Installing the Batteries
The LX-7230 functions with two "AA" size (“LR06” size) alkaline batteries.
With new batteries, the LX-7230 is capable of the following operation.
LX-7230N: approximately 2.5 days
LX-7230KM: approximately 5 days
(However, continuous operating time may be shorter than the above
mentioned time depending on the application of the SpO
WARNING
Unplug the ECG lead cable when the battery compartment lid is
opened. Otherwise, patient leakage current beyond the allowable value
may occur.
Use new "AA" size (“LR06” size) alkaline batteries.
Do not short out the (+) and (-) terminals. It may result in exothermic
heat and fire, the leakage from the batteries may damage the device, or
an explosion from the batteries may occur.
Install the batteries with the correct polarity.
Do not use a disassembled or a damaged battery due to drop or shock.
The leakage from the batteries may damage the device, or an explosion
from the batteries may occur.
Do not use different types of batteries at the same time. The leakage
from the batteries may damage the device, or an explosion from the
batteries may occur.
Remove the exhausted batteries immediately. The leakage from the
batteries may damage the device, or an explosion from the batteries
may occur.
If the transmitter is not in use for a long period of time, remove the
batteries and store the device in an appropriate place. If the batteries
are left in the transmitter for a long period of time, the leakage from the
batteries may damage the device or an explosion from the batteries
may occur.
Make sure to replace the two batteries simultaneously. If a new and
used battery are mixed, a leakage from the batteries may damage the
device or an explosion from the batteries may occur.
CAUTION
Use only alkaline batteries. Other batteries will shorten the continuous
operating time.
Once the power switch is on the OFF position, then open the battery
compartment lid.
Do not replace the batteries with wet hands.
In case of storing the used or unused batteries, make sure that the
terminals are not touching other batteries or metal parts.
