Telemetry Transmitter User Manual
Intended Use and Safety Guidance
Chapter 1 Intended Use and Safety Guidance
1.1 Intended Use/Indications for Use
Telemetry transmitter (hereinafter called iT20) must work with central monitoring system
(hereinafter called MFM-CMS) manufactured by EDAN.
Telemetry transmitter is intended to be used in clinical divisions of hospital environments,
including CCU and general wards (as Cardiology Dept., Respiratory Dept.). It is intended to be
used for adults and pediatrics. The monitored physiological parameters include: ECG, respiration
(RESP), oxygen saturation of arterial blood (SpO2) and pulse rate (PR).
1.2 Safety Guidance
Federal (U.S.) law restricts this device to sale by or on the order of a physician.
WARNING
1 Before using the device, the equipment, patient cable and electrodes etc. should be
checked. Replacement shall be taken if there is any evident defect or signs of aging
which may impair the safety or performance.
2 The electrodes expired are forbidden to be used.
3 Medical technical equipment such as telemetry monitoring system must only be used
by persons who have received adequate training in the use of such equipment and
who are capable of applying it properly. The user should have access to, and fully
read user manual (this book) before use. Harm to patient may occur if users’
operating is not in accordance with user manual.
4 It is prohibited that the operator touches battery and patient simultaneously.
5 Do not use the device with electrosurgical unit simultaneously.
6 EXPLOSION HAZARD-Do not use the device in a flammable atmosphere where
concentrations of flammable anesthetics or other materials may occur.
7 SHOCK HAZARD-To avoid the RISK of electric shock, MFM-CMS must only be
connected to a SUPPLY MAINS with protective earth. Never adapt the three-prong
plug from the MFM-CMS to fit a two-slot outlet.
8 Under simultaneous use of cardiac pacemaker and other patient-connected
equipment, the pacing impulse analysis function must be switched ON. Otherwise, the
pacing impulse may be counted as regular QRS complexes, which could prevent an
asystole event from being detected or could lead to false alarm of asystole.
9 Do not come into contact with the patient, table, or the telemetry transmitter during
defibrillation.

Telemetry Transmitter User Manual
Intended Use and Safety Guidance
WARNING
10 Extreme care must be exercised when applying medical electrical equipment. Many
parts of the human/machine circuit are conductive, such as the patient, connectors,
electrodes, transducers. It is very important that these conductive parts do not come
into contact with other grounded, conductive parts when connected to the isolated
patient input of the device. Such contact would bridge the patient's isolation and
cancel the protection provided by the isolated input. In particular, there must be no
contact of the neutral electrode and ground.
11 Magnetic and electrical fields are capable of interfering with the proper performance
of the device. For this reason make sure that all external devices operated in the
vicinity of the telemetry transmitter comply with the relevant EMC requirements. X-ray
equipment or MRI devices are a possible source of interference as they may emit
higher levels of electromagnetic radiation.
12 Route all cables away from patient’s throat to avoid possible strangulation.
13 Two batteries must be used as power supply.
14 Do not rely exclusively on the audible alarm system for patient monitoring. Adjustment
of alarm volume to a low level or off during patient monitoring may result in a hazard
to the patient. Remember that the most reliable method of patient monitoring
combines close personal surveillance with correct operation of monitoring equipment.
15 Accessory equipment connected to the analog and digital interfaces must be certified
according to the respective IEC/EN standards. Furthermore all configurations shall
comply with the valid version of the standard IEC/EN 60601-1. Therefore anybody,
who connects additional equipment to the signal input or output connector to
configure a medical system, must make sure that it complies with the requirements of
the valid version of the system standard IEC/EN60601-1. If in doubt, consult our
technical service department or your local distributor.
16 Telemetry transmitter is connected to MFM-CMS via wireless network. Therefore, any
other equipment complying with CISPR radiation requirements may also interfere with
the wireless communication and make it interrupted.
17 Telemetry transmitter will sent technical alarm information of low battery power to
MFM-CMS informing user of changing battery when battery power is 0-level.
Meanwhile, telemetry transmitter gives out a periodic sound of “du-du-du” whose
interval is 10 seconds till shutdown. After shutdown, module configuration and patient
information can be saved. User should restart the device after changing battery.
18 Clinical decision making based on the output of the device is left to the discretion of
the provider.
WARNING

Telemetry Transmitter User Manual
Intended Use and Safety Guidance
19 Only use patient cable and other accessories supplied by EDAN. Or else, the
performance and electric shock protection cannot be guaranteed, and the patient may
be injured. Prior to use, check if the casing of a disposable or sterilized accessory is
intact. Do not use it if its casing is damaged.
20 Wireless LAN equipment contains an intentional RF radiator that has the potential of
interfering with other medical equipment, including patient implanted devices. Be sure
to perform the electromagnetic compatibility test, as described in the Wireless LAN
System Installation, before installation and any time new medical equipment is added
to the Wireless LAN coverage area.
21 When interfacing with other equipment, a test for leakage current must be performed
by qualified biomedical engineering personnel before using with patients.
22 If multiple instruments are connected to a patient, the sum of the leakage currents
must not exceed the limits; or it may result in shock hazard.
23 During monitoring, if the power supply is off and there is no battery for standby, the
telemetry transmitter will be off. Last settings used will be recovered when the power
is restored.
24 When leakage or foul odor is detected，stop using
immediately.
and keep away from fire
25 The device and accessories are to be disposed of according to local regulations after
their useful lives. Alternatively, they can be returned to the dealer or the manufacturer
for recycling or proper disposal. Batteries are hazardous waste. Do NOT dispose
them together with house-hold garbage. At the end of their life hand the batteries over
to the applicable collection points for the recycling of waste batteries. Inappropriate
disposals of waste may contaminate the environment. For more detailed information
about recycling of this product or battery, please contact your local Civic Office, or the
shop where you purchased the product.
26 The packaging is to be disposed of according to local or hospital’s regulations;
otherwise, it may cause environmental contamination. Place the packaging at the
place which is inaccessible to children.
27 After defibrillation, the ECG display recovers within 10 seconds if the correct
electrodes are used and applied based on the manufacturers’ instructions.
28 When deploying wireless network, hospital should make sure that clinicians have
acknowledged and familiarized the coverage of wireless network signal. Patients’
activity must be within that range.
29 This equipment is not intended for home usage.
30 Do not service or maintain the telemetry transmitter or any accessories during patient
monitoring.

Chapter 11 Alarm Management
The contents related to this chapter are all operated on MFM-CMS.
11.1 Overview
Alarms, triggered by a physiological sign that appears abnormal or by technical problems of the
telemetry transmitter, are sent to the MFM-CMS by the telemetry transmitters and then indicated
to the users by the MFM-CMS. Alarms coming from the telemetry transmitters are displayed in
the patient sectors and in the single bed view window.
The alarm and prompts coming from the MFM-CMS system are displayed in the system
information area on the upper screen.
WARNING
A potential hazard can exist if different alarm presets are used for the same or similar
equipment in any single area, e.g. an intensive care unit or cardiac operating room.
NOTE:
The alarm signal will be delayed for no more than 5 seconds.
11.1.1 Physiological Alarms
If one or several physiological parameters of the currently monitored patient exceed the
predefined alarm limit, the telemetry transmitter will give an alarm, and this type of alarm is
called physiological alarms. It includes parameter alarm and arrhythmia alarm. About the detailed
alarm information, please refer to the Section Chapter 12 Alarm Information.
Physiological information alarm arouses the doctors’ attention by means of visual and audible
methods specified in harmonized international standard. Visual method is realized basically by
the way of lightening or flicking of the color light. Audible method is realized by the sound for
different levels.
Physiological alarms are implemented by alarm limits, which define a range in which a certain
physiological parameter is considered to be in the normal status. When a parameter value is
beyond the range, the system will consider it to be in an abnormal status and consequently give
an alarm.
11.1.2 Technical Alarms
If one or several technical status of the device is in abnormal status, the telemetry transmitter will
send an alarm to MFM-CMS. And this type of alarm is called technical alarms. Technical alarms
can’t be disabled. Technical alarms of telemetry transmitter refer to alarms other than
physiological alarms, including hardware failure, communication error, lead off, etc. About the
detailed alarm information, please refer to Section Chapter 12 Alarm Information.
- 56 -
Telemetry Transmitter User Manual
Alarm Management
For these technical alarms, the system indicates by four different types of audible and visual
prompts.
When a group of technical alarms (for example, transducer falls off) produced by telemetry
transmitters, a piece of alarm prompt information in scrolling mode will appear on the main
screen of MFM-CMS. In addition, the MFM-CMS will sound corresponding alarm (high,
medium or low level alarm).
11.1.3 Prompts
Telemetry transmitter can send the character indication of monitoring process or other functions
to MFM-CMS. This character, with black background, white font and with no alarm sound, is
called prompts. The About the detailed alarm information, please refer to Section Chapter 12
Alarm Information.
11.2 Alarm Levels
Alarm level reflects the severity of an alarm. The alarms from telemetry transmitters are divided
into three groups regarding the alarm levels.
1. High level alarms
A high level alarm intensively warns the operator of a high priority alarm condition which
requires immediate operator response. Failure to respond to the cause of the alarm condition is
likely to result in death or irreversible injury of the patient.
2. Medium level alarms
A medium level alarm warns the operator of a medium priority alarm condition which requires
prompt operator response. Failure to respond to the cause of the alarm condition is likely to result
in reversible injury of the patient.
3. Low level alarms
A low level alarm reminds the operator of a low priority alarm condition which requires response.
And the response time for a low priority alarm condition can be greater than that for a medium
priority alarm condition. Failure to respond to the cause of the alarm condition is likely to result
in discomfort or reversible minor injury of the patient.
11.3 Parameters Alarm Setting
Refer to 8.2.1 Parameters Alarm Setting for Information related to parameters alarm setting.
11.4 Alarm Mute
For information about how to set alarm mute, refer to Section 10.2.4 MFM-CMS System Alarm
Setup. Alarm mute means that when an alarm occurs, the system will not give an alarm sound but
only maintain a visual prompt.
- 57 -
Telemetry Transmitter User Manual
Alarm Management
NOTE:
Once a new alarm occurs, the system will neglect the existing settings of Alarm Mute and
generate a new alarm.
11.5 Audio Pause
Audio Pause means that during a period of time, when an alarm occurs, the system will not give
alarm announcement. The duration setting is introduced in Section 10.2.4 MFM-CMS System
Alarm Setup. By click the Audio Pause button on the main screen, you can activate or deactivate
the audio pause function.
When the duration of alarm pause has lasted for the preset-time, the system will stop the status of
alarm pause and resume normal alarm automatically.
NOTE:
Once a new alarm occurs, the system will neglect the existing settings of Alarm Voice
Pause and generate a new alarm.
11.6 Alarm Prompt/Response
Alarm information can be prompted by means of visual and audible methods. Because the alarm
information is very important and timely response to the alarm information is highly required, the
MFM-CMS provides the following methods to indicate to the user the occurrence of the alarm.

The alarm message will be displayed in the technical area or physiological area of the patient
sector and of the single bed view window.
High level alarm: displayed with red background
Medium level alarm: displayed with yellow background
Low level alarm: displayed with yellow background

An asterisk or more will be displayed before the physiological alarm message to indicate the
alarm level.
High level alarm: ***
Medium level alarm: **
Low level alarm: *

For limit alarms of the parameter, the relevant parameter value and alarm limit value will be
respectively displayed with the color alternating between the parameter color and the alarm
color.

Alarm sound
If the system mute, alarm mute or alarm pause setup is deactivated, the system will warn the user
about the alarm with the alarm sound. The sound pressure range for audible alarm signals is from
45 dB to 85 dB.
The alarm sound can be:
High level alarm: sound "DO-DO-DO DO-DO DO-DO-DO DO-DO"; The adjustable
range of alarm sound interval is from 6 to 15 seconds.
Medium level alarm: sound "DO-DO-DO"; The adjustable range of alarm sound interval is
from 6 to 30 seconds.
Low level alarm: sound "DO- ". The adjustable range of alarm sound interval is from 15 to 30
seconds.
WARNING
Do not rely exclusively on the audible alarm system for patient monitoring.
Adjustment of alarm volume to a low level or off during patient monitoring may result
in patient danger. Please remember that the most reliable method of patient
monitoring combines close personal surveillance with correct operation of monitoring
equipment.
Ensure the volume is properly set up. When the sound pressure of audible alarm is
below or equivalent to the ambient noise, it may be difficult for the operator to
distinguish the audible alarm.
11.7 Testing Alarms
When you switch the MFM-CMS on, a self-test is started. Refer to 4.2.2 Switching on/off the
MFM-CMS.
The physiological alarms, technical alarms and prompts from telemetry transmitter are displayed
on MFM-CMS. Before monitoring, user should perform the measurement on yourself or use a
simulator to check the follows:

System information area can normally display technical alarms and prompts of MFM-CMS
system;

Patient sector and single bed view can normally display physiological alarms, technical
alarms and prompts of telemetry transmitter;

Alarm sound can be heard clearly.
The correct checking above indicates that the visible and audible alarm are functioning correctly. For
further alarm tests, please adjust the alarm limits to check whether the alarm response is correct.

Monitoring ECG
Chapter 15 Monitoring ECG
15.1 Overview
The electrocardiogram (ECG) measures the electrical activity of the heart and displays it on the
telemetry transmitter as a waveform and a numeric. This chapter also tells you about arrhythmia
monitoring and ST monitoring.
15.2 ECG Safety Information
WARNING
1 Only use the ECG leads supplied by the manufacturer when using telemetry
transmitter for ECG monitoring.
2 When connecting the cables and electrodes, make sure no conductive part is in
contact with the ground. Verify that all ECG electrodes, including neutral electrodes,
are securely attached to the patient but not the conductive part or ground.
3 Check every day whether there is skin irritation resulted from the ECG electrodes. If
yes, replace electrodes every 24 hours or change their sites.
4 Place the electrode carefully and ensure a good contact.
5 Check if the lead connection is correct before monitoring. If you unplug the ECG cable
from the socket, the screen will display the error message “ECG LEAD OFF” and the
audible alarm is activated.
6 If the ECG signal exceeds the measuring range, MFM-CMS will indicates it by a
message “ECG Signal Exceeded”.
7 When using the telemetry transmitter with the defibrillator or other high-frequency
equipment, please use defibrillator-proof ECG lead to avoid burn.
8 For patients with pacemakers, the pacing impulse analysis function must be switched
ON. Otherwise, the pacing impulse may be counted as regular QRS complexes,
which could prevent an asystole event from being detected or could lead to false
alarm of asystole.
9 The electrodes should be made of the same metal materials.
10 ECG cables can be damaged when connected to a patient during defibrillation or
using other high frequency equipment. Check cables for functionality before using
them again. It is recommended to use the ECG cables which are defibrillator-proof.
11 ECG accessories are not suitable for DIRECT CARDIAC APPLICATION. (Refer to
IEC60601-1 for more information about the definition of DIRECT CARDIAC
APPLICATION.)
12 Line isolation monitor transients may resemble actual cardiac waveforms and thus
inhibit heart rate alarms. Check lead wires for damage and ensure good skin contact
prior to and during use. Always use fresh electrodes and follow proper skin
preparation techniques.
- 71 -
Telemetry Transmitter User Manual
Monitoring ECG
NOTE:
1 Interference from a non-grounded instrument near the patient and ESU interference
can cause inaccuracy of the waveform.
2 IEC/EN60601-1-2 (protection against radiation is 3v/m) specifies that the electrical
field density exceeding 1v/m may cause measurement error in various frequencies. It
is accordingly suggested that do not use equipment generating electrical radiation
near ECG/RESP monitoring devices.
3 If the pacemaker signals are beyond the claimed range, the heart rate may be
calculated incorrectly.
4 In the default settings of MFM-CMS, the ECG waveforms are the first two waveforms
from top in the waveform area.
5 For measurements in or near the heart we recommend connecting the telemetry
transmitter to the potential equalization system.
6 For protecting environment, the used electrodes must be recycled or disposed of
properly.

Changing ECG filter settings is operated on MFM-CMS.
Enter the Parameter Setup Window (way to entering refers to 8.2 Setting Parameters) > Click ECG on the
left physiological parameter list > Choose Filter > Click Update Monitor to confirm.
– Monitor: Use this mode under normal measurement conditions.
– Surgery: The filter reduces interference to the signal. It should be used if the signal is distorted
by high frequency or low frequency interference. High frequency interference usually results in
large amplitude spikes making the ECG signal look irregular. Low frequency interference usually
leads to a wandering or rough baseline. In the operating room, the Filter reduces artifacts. Under
normal measurement conditions, selecting Surgery may suppress the QRS complexes too much
and thus interfere with the clinical evaluation of the ECG displayed on the MFM-CMS.
–Diagnosis: Use when diagnostic quality is required. The unfiltered ECG waveform is displayed
so that changes such as R-wave notching or discrete elevation or depression of the ST segments
are visible.

15.8 Monitoring Procedure
15.8.1 Preparation
The skin is a poor conductor of electricity; therefore preparation of the patient's skin is important
to facilitate good electrode contact to skin.

Select sites with intact skin, without impairment of any kind.

Shave hair from sites, if necessary.

Wash sites thoroughly with soap and water. (Never use ether or pure alcohol, because this
increases skin impedance).

Rub the skin briskly to increase capillary blood flow in the tissues and remove skin scurf and
grease.
15.8.2 Connecting ECG Cables
1.
Attach clip or snap to electrodes prior to placement.
2.
Put the electrodes on the patient. Before attaching, apply some conductive jelly on the
electrodes if the electrodes are not electrolyte self-supplied.
3.
Connect the electrode lead to the patient's cable.
4.
Plug the patient cable into the ECG connector.
CAUTION
To protect the telemetry transmitter from damage during defibrillation, for accurate ECG
information and to protect against noise and other interference, use only ECG electrodes
and cables specified by EDAN.

Setting alarm source is operated on MFM-CMS.
Enter the Parameter Setup Window (way to entering refers to 8.2 Setting Parameters) > Click ECG on the
left physiological parameter list > Choose Alarm Source > Click Update Monitor to confirm.
HR: the telemetry transmitter considers the HR as HR/PR alarm source;
PR: the telemetry transmitter considers the PR as HR/PR alarm source;
AUTO: If the Alarm Source is set to Auto, the telemetry transmitter will use the heart rate from
the ECG measurement as the alarm source whenever the ECG measurement is switched on and at
least one ECG lead can be measured without a technical condition. The telemetry transmitter will
automatically switch to Pulse as the alarm source if:
–a valid ECG lead can no longer be measured and
–a pulse source is switched on and available.
The telemetry transmitter then uses the pulse rate from the measurement currently active as
system pulse. While PR is the alarm source, all arrhythmia and ECG HR alarms are switched off.
If an ECG lead becomes available again, the telemetry transmitter automatically uses HR as
alarm source.
15.11 Smart Lead Off
Choosing smart lead off is operated on MFM-CMS.
When Lead Type is 5 Leads and Smart LeadOff is set to On, if the selected ECG waveform
cannot be measured because of lead-off or other reasons, it will automatically switch to another
available lead channel via which a waveform can be measured. And the lead name above the
display ECG waveform also automatically turns into the current one.

When Pace is set to On:
- Pace Pulse Rejection is switched on. This means that pacemaker pulses are not counted as
extra QRS complexes.
- Paced symbol is displayed as | on the main screen.
NOTE:
1 When monitoring a patient with a pacemaker, set Pace to On. If monitoring a patient
without a pacemaker, set Pace to Off.
2 If Pace is set to On, the system will not perform some types of ARR analysis.
WARNING
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.

15.15.4 About ST Measurement Points
The ST value for each beat complex is the vertical difference between the ISO point and the ST
point, as shown in the diagram below. The isoelectric (ISO) point provides the baseline, and 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.

DEF POINT
About ISO and ST measurement points:
For telemetry transmitters, the location of ISO and ST measurement points is not adjustable. Its
initial value for ST testing points is +84ms by default. ST analysis takes no account of abnormal
QRS wave.
15.16 Arr. Monitoring
15.16.1 Arrhythmia Analysis
The arrhythmia algorithm is used to monitor ECG of adult patients in clinics, and detect the
changes of heart rate and ventricular rhythm, and also save arrhythmia events and generate
alarming information. The arrhythmia analysis is not clinically validated for use with neonatal
and pediatric patients. Arrhythmia algorithm can monitor paced and non-paced patients. Qualified
personnel can use arrhythmia analysis to evaluate patient’s condition (such as heart rate, PVCs
frequency, rhythm and ectopic beat) and decide the treatment. Besides detecting change of ECG,
arrhythmia algorithm can also monitor patients and give proper alarm for arrhythmia.
Telemetry transmitter can support up to 16 different arrhythmia analyses.

Monitoring RESP
Chapter 16 Monitoring RESP
16.1 Overview
Telemetry transmitter measures respiration from the amount of thoracic impedance between two
ECG electrodes. The change of impedance between the two electrodes, (due to the thoracic
movement), produces a respiratory waveform on the screen.
16.2 RESP Safety Information
WARNING
1 The respiration measurement does not recognize obstructive and mixed apneas - it
only indicates an alarm when a pre-adjusted time has elapsed since the last detected
breath.
2 If operating under conditions according to the EMC Standard EN 60601-1-2 (Radiated
Immunity 3V/m), field strengths above 1V/m may cause erroneous measurements at
various frequencies. Therefore it is recommended to avoid the use of electrically
radiating equipment in close proximity to the respiration measurement unit.
3 Cardiogenic artifact in impedance respiration monitoring may make it difficult to detect
breaths or may otherwise be counted as breaths. In some instances, the breath rate
may also correspond to the heart rate making it difficult to determine if the signal is
due to breathing or the cardiac cycle. Do not rely on RESP monitoring as the sole
method for detecting cessation of breathing. Follow hospital guidelines and best
clinical practices for apnea detection including monitoring additional parameters that
indicate the patient’s oxygenation status, such as EtCO2 and SpO2.
NOTE:
The RESP monitoring is not recommended to be used on patients who are very active, as
this can cause false alarms.
16.3 Electrode Placement for Monitoring RESP
Correct patient skin preparation techniques for electrode placement are important for RESP
measurement: you will find this information in the chapter on ECG.
The RESP signal is always measured between two of the ECG electrodes. There is only one
standard ECG lead for telemetry transmitter: II lead (RA and LL).

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 respiratory electrodes.
16.5 Chest Expansion
Some patients, expand their chests laterally. In these cases it is best to place the two respiratory
electrodes in the right midaxillary and left lateral chest areas at the patient’s maximum point of
breathing movement to optimize the respiratory wave.
16.6 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 respiratory wave.
NOTE:
Place the red and green electrodes diagonally to optimize the respiration waveform.
Avoid the liver area and the ventricles of the heart in the line between the RESP
electrodes so as to avoid cardiac overlay or artifacts from pulsating blood flow.
16.7 Selecting RESP Lead
II lead is constant as the RESP lead.
16.8 Changing the Apnea Time
Changing the apnea time is operated on MFM-CMS.

Monitoring SpO2
Chapter 17 Monitoring SpO2
17.1 Overview
SpO2 is based on the absorption of pulse blood oxygen to red and infrared light by means of
finger sensor and SpO2 measuring unit. SpO2 Plethysmogram measurement is employed to
determine the oxygen saturation of hemoglobin in the arterial blood. If, for example, 97% of the
hemoglobin molecules in the red blood cells of the arterial blood combine with oxygen, then the
blood has a SpO2 oxygen saturation of 97%. The SpO2 numeric on the telemetry transmitter will
read 97%. The SpO2 numeric shows the percentage of hemoglobin molecules which have
combined with oxygen molecules to form oxyhemoglobin. The SpO2/PLETH parameter can also
provide a pulse rate signal and a plethysmogram wave.
17.2 SpO2 Safety Information
WARNING
1 If the SpO2 sensor cannot work properly, please reconnect the sensor or change a
new one.
2 Do not use the sterile supplied SpO2 sensors if the packaging or the sensor is
damaged and return them to the vendor.
3 Prolonged and continuous monitoring may increase the risk of unexpected change of
dermal condition such as abnormal sensitivity, rubescence, vesicle, repressive
putrescence, and so on. It is especially important to check the sensor placement for
the patients of poor perfusion or immature dermogram by light collimation and proper
attaching strictly according to changes of the skin. More frequent examinations may
be required for different patients.
4 Tissue damage may be caused by incorrect application or prolonged measurement
duration using the sensor (more than 4 hours). Inspect the sensor periodically
according to the sensor user manual.
5 Use only EDAN permitted sensors and extension cables with the oximeter. Other
sensors or extension cables may cause improper telemetry transmitter performance
and/or minor personal injury.
NOTE:
1 Make sure the nail covers the light window. The wire should be on the backside of the
hand.
2 SpO2 waveform is not proportional to the pulse volume.
3 Avoid placing the sensor on extremities with an arterial catheter, or intravascular
venous infusion line.
4 Don’t use the functional tester or patient simulator to assess the SpO2 accuracy.
- 87 -
Telemetry Transmitter User Manual
Monitoring SpO2
5 The device is calibrated to display functional oxygen saturation.
6 The materials with which the patient or any other person can come into contact
conform with the standard of EN ISO 10993-1: 2009.
7 SpO2 waveform is not proportional to the pulse volume.
8 When the SpO2 value is potentially incorrect, it will display “?”.
17.3 Measuring SpO2
1.
Select the correct Type in the patient management window (Adult/ Pediat) and click Update
Monitor to confirm, as this is used to optimize the calculation of the SpO2 and pulse
numerics.
2.
During measurement, ensure that the application site:
– has a pulsatile flow, ideally with a good circulation perfusion.
– has not changed in its thickness, causing an improper fit of the sensor.
17.4 Measurement Procedure
1. Switch on telemetry monitoring system.
2. Attach the sensor to the appropriate site of the patient finger.
3. Plug the connector of the sensor extension cable into the SpO2 socket on telemetry
transmitter.
Mounting of the Sensor
WARNING
Inspect the application site every two to three hours to ensure skin quality and correct
optical alignment. If the skin quality changes, move the sensor to another site. Change
the application site at least every four hours.
NOTE:
Injected dyes such as methylene blue or intravascular dyshemoglobins such as
methemoglobin and carboxyhemoglobin may lead to inaccurate measurements.
Interference can be caused by:

High levels of ambient light or strobe lights or flashing lights (such as fire alarm lamps).
- 88 -
Telemetry Transmitter User Manual
Monitoring SpO2
(Hint: cover application site with opaque material.)

High-frequency electrical noise, including electro-surgical apparatus and defibrillators

Intravascular dye injections

Significant concentrations of dysfunctional hemoglobin, such as carboxyhemoglobin and
methemoglobin

Excessive patient movement and vibration

Improper sensor application

Low perfusion or high signal attenuation

Venous pulsation

Placement of the sensor on an extremity that has a blood pressure cuff, arterial catheter, or
intravascular line
17.5 Assessing the Validity of a SpO2 Reading
You can check the quality of the pleth wave and the stability of the SpO2 values to assess whether
the sensor functions properly and whether the SpO2 readings are valid. Always use these two
indications simultaneously to assess the validity of a SpO2 reading.
Generally, the quality of the SpO2 pleth wave reflects the quality of the light signals obtained by
the sensor. A wave of poor quality manifests a decline of the signal validity. On the other hand,
the stability of the SpO2 values also reflects the signal quality. Different from varying SpO2
readings caused by physiological factors, unstable SpO2 readings are resulted from the sensor’s
receiving signals with interference. The problems mentioned above may be caused by patient
movement, wrong sensor placement or sensor malfunction. To obtain valid SpO2 readings, try to
limit patient movement, check the placement of the sensor, measure another site or replace the
sensor.
NOTE:
1. The SpO2 accuracy has been validated in human studies against arterial blood
sample reference measured with a CO-oximeter. Pulse oximeter measurements are
statistically distributed, only about two-thirds of the measurements can be expected
to fall within the specified accuracy compared to CO-oximeter measurements. The
volunteer population in the studies composed of local healthy men and women from
age 19 to 37, with various skin pigmentations.
2. The pulse rate accuracy is obtained by comparison to the pulse rate generated with
an arterial oxygen simulator (also an electronic pulse simulator).

Monitoring SpO2
17.6 SpO2 Alarm Delay
There is a delay between a physiological event at the measurement site and the corresponding
alarm at the MFM-CMS. This delay has two components:
1.
The time between the occurrence of the physiological event and when this event is
represented by the displayed numerical values. This delay depends on the algorithmic
processing time and the sensitivity setting. The lower the sensitivity configured, the longer
the time needed until the numerical values reflect the physiological event.
2.
The time between the displayed numerical values exceeding an alarm limit and the alarm
indication on the MFM-CMS. This delay is the combination of the configured alarm delay
time plus the general system delay time.
17.7 Setting Sensitivity
Setting sensitivity is operated on MFM-CMS.
The different sensitivity indicates different refresh frequency. High indicates the refresh
frequency of SpO2 value is the most frequent. To change the sensitivity, please:
Enter the Parameter Setup Window (way to entering refers to 8.2 Setting Parameters) > Click
SpO2 on the left physiological parameter list > Click Sensitivity (High, Med and Low are
optional) > Click Update Monitor to confirm.
17.8 SpO2 Alarm Settings
SpO2 alarm settings are operated on MFM-CMS. Use can open or close the ECG alarm.

Monitoring PR
Chapter 18 Monitoring PR
18.1 Overview
The pulse numeric counts the arterial pulsations that result from the mechanical activity of the
heart in beats per minute (bpm). You can display a pulse from any measured SpO2 signal.
18.2 Selecting the Active Alarm Source
In most cases, the HR and Pulse numerics are identical. In order to avoid simultaneous alarms on
HR and Pulse, the telemetry transmitter uses either ECG or Pulse as its active alarm source.
Selecting active alarm source is operated on MFM-CMS.
Enter the Parameter Setup Window (way to entering refers to 8.2 Setting Parameters) > Click PR
on the left physiological parameter list > Click Alarm Source (HR, PR and AUTO are
optional) > Click Update Monitor to confirm.

HR: if you want HR to be the alarm source for HR/Pulse.

PR: if you select Pulse as the alarm source, ECG HR alarms are switched off.

AUTO: If the Alarm Source is set to Auto, the telemetry transmitter will use the heart rate
from the ECG measurement as the alarm source whenever the ECG measurement is switched
on and at least one ECG lead can be measured without a technical condition. The telemetry
transmitter will automatically switch to Pulse as the alarm source if:
–a valid ECG lead can no longer be measured and
–a pulse source is switched on and available.
The telemetry transmitter then uses the pulse rate from the measurement currently active as
system pulse. While PR is the alarm source, all arrhythmia and ECG HR alarms are switched
off. If an ECG lead becomes available again, the telemetry transmitter automatically uses HR
as alarm source.
NOTE:
Pulse alarms are only generated when the active alarm source is set to PR, a pulse
source is set as system pulse and pulse alarms are switched on.
18.3 PR Alarm Settings
PR alarm settings are operated on MFM-CMS. Use can open or close the ECG alarm.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess
the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which
iT20 is used exceeds the applicable RF compliance level above, iT20 should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating iT20.
Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
B.4 Recommended Separation Distances
Recommended separation distances between
