2.1 Introduction
The B40/B20 monitor build up a freely configurable modular system. The architecture is
designed to enable different module combinations so that the user is able to get the desirable
parameter and feature set. This modular approach makes it possible to add new features
when they are needed.
2.2 Bus structure
The operation of monitor is based on two communication channels, the CPU bus and module
bus. All units, including the modules, receive power from the same power supply, which is an
integral part of the monitor frame.

LCD DATA BUS
General bus structure of monitor
The CPU bus is a communication channel used only for internal data transfer. It is based on the
AT91 ARM local bus. Data and address are transferred on this 32 bit wide bus using the CPU
clock frequency.
The module bus is for the parameter modules. The bus is based on the industry standard
RS-485, which uses a differential serial method to transfer data. The module bus uses a 500
kbps data transfer rate.
1-11
Document no. 2050802-001
B40/B20 Patient Monitor
The RS-485 type of serial communication supports so-called multidrop or party line
connections. This means that all parameter modules connected to the module bus use exactly
the same lines for communication. The advantage of this is that all bus connectors are
identical and the modules can be connected in any order and position.
2.3 Distributed processing
This is a multiprocessor system. All parameter modules have their own microprocessor, which
performs functions such as waveform filtering, parameter related computing and pneumatic
control, etc. At the same time the main CPU performs higher level tasks such as trending and
alarm control. While the parameter modules and CPU are performing their tasks, the UPI
(Universal Peripheral Interface) microprocessor handles all functions needed to transfer data
between the parameter modules and the CPU.
This kind of parallel processing gives one major advantage to centralized processing. When
new parameter modules are added to the system, the processing power is increased. As a
result, the system does not slow down when new features are added.
2.4 Module communication
The communication master controlling data transfers between the CPU and parameter
modules is called UPI processor. It sends data to each connected module 100 times a second.
Modules respond to each data request immediately by sending a data package, whose length
depends on the type of the module. This communication protocol ensures that each module
receives and sends data every 10 ms. If a module does not respond to data requests, the UPI
processor presumes that the module is disconnected.
The data transfered on USB bus between main CPU and UPI processor.

General structure of parameter modules with patient isolation
The detailed structure of a parameter module depends on the specific needs for each
individual parameter. However, some common parts are used in the parameter modules. The
electronics inside the module is usually divided into isolated (floating) and non-isolated
sections. Typically, the non-isolated section consists of buffers to interface the parameter
module to the module bus while the rest of the electronics is located in the isolated section. The
isolated section includes the microcontroller together with memory components, the front-end
analog electronics (amplifiers, etc.) and sensor drivers.

Hemo-dynamic module introduction
Signal processing
Two signals from the pressure transducers are amplified and sent to the A/D converter. After
the converter, digitized signals are sent to the microprocessor for data processing.
The NIBP board is controlled with an ARM7 microprocessor at 16 MHz oscillator frequency.
Memory
The NIBP program memory (processor flash memory) size is 256k x 8. The processor has 64
kBytes RAM. The EEPROM size is 8K x 8 and it is used to store the calibration values for the
pressure transducers, the pulse valve constants gained during measurements, the PC board
identification, and the module serial number.
Software control
The software controls valves and a pump. In addition to the individual on/off signals for each
component there is a common power switch for the valves and the pump that can be used at
pump/valve failures.
Safety circuit
The NIBP board is equipped with an independent safety circuit to disconnect supply voltages
from the pump and the valves if the cuff has been pressurized longer than the preset
maximum measurement time, or if the pressure of the cuff is inflated over the specified
pressure limit. The maximum measurement time values and pressure limits for different
measurement modes have been specified in the technical specification section of this manual.

pressure fluctuations caused by arterial wall movement.
6.
Second pressure sensor; for detecting the, cuff loose, cuff occlusion situations, etc. and
for recognizing the pressure sensor fault.
7.
Cuff connector; for connection and hose identification.
Power supply section of the NIBP board
All connections are established via a 10-pin connector (male). The module needs a +15 V (dirty)
power supply to operate. The supply voltage Vmod 15V +/- 3% is generated in the power
supply section of the monitor. The other voltages needed for the operation of the NIBP
measurement are made on the NIBP board.
The NIBP power supply synchronizes the ECG and STP isolation power and supplies
non-isolated 5 V to the ECG and STP board.

ECG input unit
The ECG input unit consists of the front panel connector and the ECG input connector board
with the high voltage protection resistors. The connector for the ECG cable is a green 11-pin
rectangle shaped connector.
Input protection and filtering
The input protection is implemented with high voltage protection resistors in the ECG input unit
and with protection diodes in the ECG board. The input filtering for ECG measurement is done
with passive RC filtering.
ECG preamplifiers
The buffer amplifiers are used for each lead. The “Leads off” detection is implemented by
measuring the output level of the input buffer amplifiers with the A/D converter of the CPU. The
ECG signals are measured using differential amplifiers.

B40/B20 Patient Monitor
ECG amplifiers and baseline restoration
The function of the ECG amplifiers and baseline restoration is to amplify the signal and to
restore the baseline of the signal in the middle of the display after the change of the signal
level, e.g. after the change of the DC offset voltage.
Pacemaker detection
Pacer detection has been made by using four slew rate detector circuits. The pacer detection
amplifiers have been realized at the front of the slew rate detectors independently of the ECG
measuring channels.
Respiration impedance supply
The 31.25 kHz sine wave generator is used as the respiration measurement signal supply.
Analog switches are used for connecting the sine wave to the ECG leads to be measured.
Respiration impedance amplifiers
Buffer amplifiers are used in respiration measurement. Analog switches are used for selecting
the measurement leads. There are also additional amplifiers for increasing the respiration
signal gain. When ECG measurement is 5-lead, the respiration measurement is always done
between R and F, independently on the ECG lead selection. When ECG measurement is 3-lead,
then the respiration measurement is happened at the same lead as the ECG measurement (I, II
or III).
ECG CPU
The CPU is a 16 bit H8/3052 single-chip microcomputer. It contains 128 kbytes of flash
memory and 4 kbytes of RAM. The clock frequency is 16 MHz.
RS485 communication
The communication to the CPU board of the monitor uses RS485 protocol. The RS485 driver
circuits are optically isolated from the processor of the module.
Power supply
The ECG board has a driver-controlled half-bridge switching power supply with 5 kV isolation.
The supply voltages have been regulated with linear regulators.
4.2.4 ECG filtering
B40/B20 monitors have three ECG filtering modes:
MONITORING
DIAGNOSTIC
ST FILTER
0.5 to 40 Hz
0.05 to 150 Hz
0.05 to 40 Hz
The purpose of filtering is to reduce high frequency noise and low frequency (e.g. respiratory)
movement artifacts.
The monitor filter is used in normal monitoring. The diagnostic filter is used if more accurate
diagnostic information is needed. The ST filter gives more accurate information of ST segment,
but reduces high frequency noise.
The high-pass filters 0.5 Hz and 0.05 Hz are done with software. The monitor sends a command
to the hemodynamic module determining which of the corner frequencies 0.5 Hz or 0.05 Hz is
to be used.
The 50 Hz and 60 Hz reject filters are both low-pass filters with zero at 50 Hz or 60 Hz
correspondingly. They are software based filters used for the mains supply filtering.
In diagnostic mode the upper frequency is 150 Hz and it is limited by software.

Hemo-dynamic module introduction
4.2.5 STP board
STP module measures SpO2, two channels of temperatures and two channels of invasive blood
pressures.
The SpO2 measurement is made optically with an infrared light, a red light sources, and a
photosensitive detector. The SpO2 value and Pulse Rate are calculated based on the signals,
which are measured with the photosensitive detector in the SpO2 sensor. There are three
configurations of SpO2: GE SpO2, Masimo SpO2 and Nellcor SpO2. There are four kinds of STP
parameter board:

GE SpO2 board

STP board, integrated GE SpO2, Temperature and pressure

TP board, integrated Temperature and pressure, communicated with Masimo OEM SpO2
through UART port to get SpO2 data and send to host.

TP board, integrated Temperature and pressure, communicated with Nellcor OEM SpO2
through UART port to get SpO2 data and send to host.
The temperature measurement is designed for use with YSI-400 series NTC sensors.

The NTC-resistor value in the probe depends on the patient’s temperature. It is measured with
the following principle described below.
The constant current source is supplied about 38 A current through the temperature sensor
(YSI 400-series NTC resistor). The constant current is caused a voltage over the temperature
sensor (NTC resistor). The voltage over the temperature sensor is amplified in a differential
amplifier stage. The amplified voltage is transferred to a controller of the STP board through an

Invasive blood pressure measurement unit
An isolated +5 V voltage is supplied to the pressure transducer. The differential voltage, which
depends on the pressure and the supplied voltage, is calculated from the bridge connection
(see the formula below).
Uout = Uin  pressure  5 V, where Uin is 5 V
 Uout = 25 V  pressure [mmHg]
Pressure amplification is realized in the instrumentation amplifier. The gain of the amplifier is
set to keep the level of the signal transferred to the A/D converter within the measurement
range even when there are circumstantial offsets or offsets caused by the transducer. There is
a filter before the amplifier to attenuate high frequency disturbances.

LED control signals
The D/A converters of the microcontroller on the STP board set the LED intensity adjustment
values for the infrared and red LEDs of the SpO2 probe. The microcontroller on the STP board
switches ON (to the adjusted intensity) and OFF the SpO2 probe LEDs according to the
predetermined sequence.
LED driving circuit
Differential amplifiers measure the LED currents (LED current indication) of the SpO2 probe over
the shunt resistors placed in the LED current paths. The LED driving voltages (LED voltage
indication) are measured from the driver circuitry. The LED driving circuits also have MOSFET
transistor matrix to enable the use of different probe configurations.
Measured signal preamplification
The preamplifier is a bipolar/single-ended current-to-voltage converter with adjustable gain. A
higher gain is used for measuring thin tissue. The preamplification stage has also ambient light
reduction and a second amplifier stage.

4.4 Measurement principle
4.4.1 NIBP
NIBP (Non-Invasive Blood Pressure) is an indirect method for measuring blood pressure.
The NIBP parameter conforms to EN1060-1:1995/A2:2009 Specification for Non-invasive
sphygmomanometers.
The NIBP measurement is performed according to the oscillometric measuring principle. The
cuff is inflated with a pressure slightly higher than the presumed systolic pressure, and
deflated at a speed based on the patient’s pulse, collecting data from the oscillations caused
by the pulsating artery. Based on these oscillations, values for systolic, mean, and diastolic
pressures are calculated.
The following parts are necessary for the NIBP measurement:
•
•
•
hemo module
twin hose (adult or infant model)
blood pressure cuffs (various sizes)
4.4.2 ECG
Electrocardiography analyzes the electrical activity of the heart by measuring the electrical
potential produced with electrodes placed on the surface of the body.
ECG reflects:
•
•
•
•
electrical activity of the heart
normal/abnormal function of the heart
effects of anesthesia on heart function
effects of surgery on heart function
See the “User's Guide” or the “User’s Reference Manual” for electrodes’ positions and other
information.
4.4.3 Pulse oximetry
A pulse oximeter measures the light absorption of blood at two wavelengths, one in the near
infrared (about 940 nm) and the other in the red region (about 660 nm) of the light spectrum.
These wavelengths are emitted by LEDs in the SpO2 probe, the light is transmitted through
peripheral tissue and is finally detected by a PIN-diode opposite the LEDs in the probe. The
pulse oximeter derives the oxygen saturation (SpO2) using an empirically determined
relationship between the relative absorption at the two wavelengths and the arterial oxygen
saturation SaO2.
In order to measure the arterial saturation accurately, pulse oximeters use the component of
light absorption giving variations synchronous with heart beat as primary information on the
arterial saturation.
A general limitation of pulse oximetry is that due to the use of only two wavelengths, only two
hemoglobin species can be discriminated by the measurement.
The modern pulse oximeters are empirically calibrated either against fractional saturation
SaO2frac;

or against functional saturation SaO2func;
SaO 2 func 
HbO 2
HbO 2  Hb
Formula 2
Functional saturation is more insensitive to changes of carboxyhemoglobin and
methemoglobin concentrations in blood.
The oxygen saturation percentage SpO2 measured by the Datex-Ohmeda module is calibrated
against functional saturation SaO2func. The advantage of this method is that the accuracy of
SpO2 measurement relative to SaO2func can be maintained even at rather high concentrations
of carboxyhemoglobin in blood. Independent of the calibration method, pulse oximeters are
not able to correctly measure oxygen content of the arterial blood at elevated
carboxyhemoglobin or methemoglobin levels.
Plethysmographic pulse wave
The plethysmographic waveform is derived from the IR signal and reflects the blood pulsation
at the measuring site. Thus the amplitude of the waveform represents the perfusion.
Pulse rate
The pulse rate calculation is done by peak detection of the plethysmographic pulse wave. The
signals are filtered to reduce noise and checked to separate artifacts.

Pulse oximetry probe parts layout and schematic diagram
The standard probe is a finger clamp probe which contains the light source LEDs in one half
and the photodiode detector in the other half. Different kinds of probes are available from GE
Healthcare.
4.4.4 Temperature
The temperature is measured by a probe whose resistance varies when the temperature
changes, called NTC (Negative Temperature Coefficient) resistor.
The resistance can be measured by two complementary methods:
•
Applying a constant voltage across the resistor and measuring the current that flows
through it.
•
Applying a constant current through the resistor and measuring the voltage that is
generated across it.
Hemo module uses the constant current method. The NTC-resistor is connected in series with a
normal resistor and a constant current is applied through them. The temperature dependent
voltage can be detected at the junction of the resistors, thus producing the temperature signal
from the patient. The signal is amplified by analog amplifiers and further processed by digital
electronics.
4.4.5 Invasive blood pressure
To measure invasive blood pressure, a catheter is inserted into an artery or vein. The invasive
pressure setup, consisting of a connecting tubing, a pressure transducer, an intravenous bag
of normal saline, all connected together by stopcocks, is attached to the catheter. The
transducer is placed at the same level with the heart, and is electrically zeroed.
The transducer is a piezo-resistive device that converts the pressure signal to a voltage. The
monitor interprets the voltage signal so that pressure data and pressure waveforms can be
displayed.

Hemo-dynamic module introduction
4.4.6 Respiration
Impedance respiration is measured across the thorax between ECG electrodes. The respiration
signal is made by supplying current between the electrodes and by measuring the differential
current from the electrodes. The signal measured is the impedance change caused by
breathing. The respiration rate is calculated from these impedance changes, and the
respiration waveform is displayed on the screen.

Electrical Safety Tests
2.1 General
Electrical safety tests provide a method of determining if potential electrical health hazards to
the patient or operator of the device exist.
2.2 Recommendations
GE recommends that you perform all safety tests presented in this chapter.
•
•
•
Upon receipt of the device (monitor and its associated equipment).
Every twelve months thereafter planned maintenance
Each time the main enclosure is disassembled or a circuit board is removed, tested,
repaired, or replaced
These instructions are intended for every component in the system. GE recommends that the
qualified personnel performing the tests.
2.3 Test Equipment
The recommended test equipment required to perform electrical safety tests is listed below.

Instead of the test bodies included in the safety test body kit, other applicable test
bodies with all pins connected together may be used.
Perform electrical safety tests using an electrical safety analyzer per IEC 60601-1, UL 60601-1,
EN 60601-1 or CSA C22.2 No. 601.1. The schematics in the section provide a general
understanding of the test equipment. Actual configuration of test equipment may vary.
The patient monitor being tested should be placed on an insulating surface.
2.4 Power Outlet Test
Verify that the power outlet is wired correctly per the country’s electrical code standard before
starting the following electrical safety tests. The results of the following tests will be inaccurate
unless a properly wired power outlet is used. Use only non-isolated power outlets when
performing safety tests.

B40/B20 Patient Monitor
2.5 Power cord and plug
Verify the power cord being used with the patient monitor is good. The following are a couple
of things to check for in this regard:
•
Failure of the power cord strain relief is very common. Often times users of the equipment
pull on the power cord itself, rather than the power cord plug, to unplug the patient
monitor from a wall receptacle. If in doubt, test for continuity through each conductor of
the power cord connector and plug.
•
Verify line, neutral, and earth conductors are properly connected to the power cord plug
and are not short-circuited. Replace the power cord, as necessary with a
regulatory-approved cord for the country of use.

WARNING
Use only AC power cords recommended or manufactured by GE.
2.6 Ground (Earth) Integrity
Listed below are two methods for checking the ground (earth) integrity, “Ground Continuity
Test” and “Impedance of Protective Earth Connection.” These tests determine whether the
device's exposed metal and power inlet's earth (ground) connection has a power ground fault
condition
Perform the in accordance with your local regulations.
Refer to the instructions contained with the safety analyzer to perform each test.
2.6.1 Ground Continuity Test
The measuring device (MD) in the diagram below may be a DMM or part of a safety analyzer.

Electrical Safety Tests
Acceptance criteria:
• For equipment without a power supply cord, the impedance between the protective earth
terminal and any accessible metal part which is protectively earthed shall not exceed 0.1
ohms.
•
For equipment with a power supply cord, the impedance between the protective earth
pin in the mains plug and any accessible metal part which is protectively earthed shall
not exceed 0.2 ohms.
2.6.2 Impedance of Protective Earth Connection
This test, unlike a ground continuity test, will also stress the ground system by using special
ground bond testers.
This test normally is only required as a manufacturing production test to receive safety agency
compliance. Some country agencies do require this test after field equipment repairs (e.g.,
Germany’s DIN VDE 0751 standards). Consult your country/local safety agency if in question.
Compliance is checked by the following steps:
(1)
A current of 25A from a current source with a frequency of 50 or 60 Hz with a no-load
voltage not exceeding 6 V is passed for at least 5 seconds, but no more than 10 seconds,
through the protective earth terminal or the protective earth pin in the mains plug and
each accessible metal part which could become live in case of failure in basic insulation.
(2)
The voltage drop between the parts described is measured and the impedance
determined from the current and voltage drop. It shall not exceed the values indicated.
When taking this measurement, move the unit’s power cord around. There should be no
fluctuations in resistance.

Acceptance criteria
•
For equipment without a power supply cord, the impedance between the protective earth
terminal any accessible metal part which is protectively earthed shall not exceed 0.1
Ohms.
•
For equipment with a power supply cord, the impedance between the protective earth
pin in the mains plug and any accessible metal part which is protectively earthed shall
not exceed 0.2 ohms.
2.7 Ground (earth) wire leakage current tests

3.3 Power supply
The menu shows the voltages and
temperature measured by the power board
and CPU board. The values in the column
under Mean are the mean values of last
one second, the Min column shows the
minimum mean value, and the Max column
the maximum mean value of the voltages
and temperature measured during the
current power ON.
The voltages and currents are measured by
the power Board, except the four lowest
under heading CPU Board A/D, which are
measured by the CPU Board. +5V and +3.3V
values come thus both from the power
Board and CPU Board. System power and
Module power are calculated by the power
Board.

Module configuration shows which measurement
options are available, i.e. are detected by the module.
Timeouts is a cumulative number that indicates how
many times the module has not responded to the
monitor's inquiry.
Bad checksums is a cumulative number that indicates
how many times communication from the module to
monitor has broken down.

Bad c-s by mod is a cumulative number that indicates
how many communication errors the module has
detected.
The monitor starts counting these items at power up
and resets to zero at power off. The values may also be
reset when a module is attached to the monitor frame
and be set to 32769 or continuous counting may be
started when the module is removed from the monitor
frame.

The nonzero values do not indicate a failure, but the
continuous counting (more than 5 per second) or value
32769 indicates either a serial communication failure or
a module not in place. Also failures in other modules
may cause these numbers to rise or be set to 32769.

Bad c-s by mod is a cumulative number that indicates how many communication errors the
module has detected.
The monitor starts counting these items at power up and resets to zero at power off. The values
may also be reset when a module is attached to the monitor frame and be set to 32769 or
continuous counting may be started when the module is removed from the monitor frame.
The nonzero values do not indicate a failure, but the continuous counting (more than 5 per
second) or value 32769 indicates either a serial communication failure or a module not in place.
Also failures in other modules may cause these numbers to rise or be set to 32769.
RAM indicates the state of the RAM memory.
ROM indicates whether the checksum at the EPROM is in accordance with the one the software
has calculated.
EEPROM indicates if the values stored in the permanent memory are valid.
The state is either OK, Fail or ? (module not in place or a communication error).
LeadsOff indicates whether the monitor can measure ECG even if one or more leadwires are off:
1 = measurement is not possible, 0 = measurement can be done.
MissedPkgs indicates the number of packages missed.
4.2.1 ECG Setup
Filter filters the ECG signal high frequency noise and
slow respiratory artifacts:
-
-
-
ECG Module
Monit (monitor) filter is used in routine monitoring.
It effectively filters the artifacts caused by the
electrosurgery unit and respiration.
Diagn (diagnostic) filter is used if more accurate
information of the waveform is needed (e.g. of
P-wave or AV block). The diagnostic filter is more
susceptible both to high frequencies and baseline
wander than the monitor filter.
STfilt (ST filter) permits more accurate information
of ST segment. It filters the high frequency artifacts
caused by the electrosurgery unit, but catches the
slow changes in ST segment. The ST filter is more
susceptible to baseline wander than the monitor
filter.
Pacemaker selects how to display the pacing pulse of
cardiac pacemaker. The selections are Show, Hide
and Sensit:
-
Hide: the pacing pulse is filtered away from ECG
data.
-
Show: the pacer pulse is filtered away from ECG
data but the pulse is displayed as a constant
height marker.
-
Sensit: uses a more sensitive pacemaker
detection. Pacemaker spike is displayed on ECG.

Set/Test
The system contains a watchdog circuitry, which
needs refreshment at every 10 seconds. If the
refreshment did not occur, the watchdog will reset
the main CPU.
The purpose of the watchdog is to restart the
monitor, if there was a serious malfunction. This
feature is useful in two cases: when the main CPU is
not able to control the monitor, or when the CPU
controls the monitor but detects a serious
malfunction. Watchdog tests check proper
functionality of the watchdog in various conditions.

The test should have the following result when the
watchdog is working properly: The monitor will
restart after 10 seconds from the start of the test. In
malfunction: ‘>20 s’ is displayed. In this case, the
fault is in the watchdog.
WD by Overload test ensures the functionality of a feature, where the
software controls the monitor, but detects an overload situation in the main
CPU.
The test should have the following result when the feature is working properly:
The monitor will restart after 10 seconds from the start of the test.
Factory Reset restores the factory default settings and clears the data
memories. Factory reset should be run if the monitor software is replaced or if
the Timekeeper battery is replaced.

2.6 Handling and storage of LCD display component
Handling of LCD display component and protective window
If the LCD Display component surface becomes dusty, wipe it gently with absorbent cotton,
chamois or other soft material. If necessary, breathe onto the display surface and wipe
immediately. The display surface may also be cleaned using a small amount of normal
hexane. Do not use acetone, toluene or alcohol because they cause chemical damage to the
polarizer.
1.
Wipe off saliva and water drops as soon as possible. Their prolonged contact with the
polarizer cause deformations and color fading.
2.
Do not open the component case because internal circuits are sensitive to electrostatic
discharges.
Placing a spare part LCD Display component or a display shield into use:
Peel off the protective film slowly (in more than 10 seconds) from the display or protective
window surface. Fast peeling may generate enough static electricity to destroy the LCD
Display component.
Storaging an LCD display component as a spare part for a long period
1.
Store the display in a dark place. Do not expose it to sunlight or fluorescent light. Keep the
temperature between -30 °C and 85 °C / -22 °F and 185 °F at 5% to 95% humidity.
2.
The polarizer surface should not come into contact with any other object. It is
recommended that the display unit is stored in the container in which it was originally
shipped.

2.7 Batteries
2.7.1 Battery indicators
The B40/B20 messages, screen symbols and the LED indicators tell the user about the status of
the batteries. For screen symbols, see “Part 1 Symbols”. For LED indicators, consult the table
below and for messages, see section “Troubleshooting.” in User’s Guide.
The Green main LED will indicate that monitor is powered by Main. The Green battery LED will
indicate that monitor is powered by battery. The Orange battery LED lit will indicate that the
battery is in charging. The Orange battery LED flashing will indicate that the battery is defect. If
the battery is fully charged and it’s main powered. the orange and Green battery LED will both

2.7.3 Conditioning the batteries
Condition the batteries regularly to maintain their useful life. Condition a battery every six
months or when the message ‘Condition Battery x’‘ appears on the screen. Always observe the
messages and symbols on the screen to see the battery status. You can also check the status
through Monitor Setup - Battery Setup. Conditioning a battery is best done on an external
charger. If you do not have an external charger, proceed according to the following
instructions.
NOTE: You cannot condition batteries during patient monitoring. Always disconnect the
modules first.
1.
Continue normal battery use until the green bar of a battery charge indicator is less than
3/4 of the full height. After this, remove the battery. Continue monitoring with one battery
until its charge is less than 3/4 of the full capacity.
2.
Insert both batteries and connect the monitor to the power supply. The monitor starts
charging both batteries, and the capacity indicators scroll accordingly. Keep charging the
batteries until both capacity indicators are full height.
3.
Continue charging for another two hours. After this, check that the orange battery LED in
the front panel is no longer on. If it is, continue charging until it goes off.
4.
Disconnect the monitor from the power supply and leave it on until the batteries run out
and the monitor switches off. Wait for another 15 minutes.
5.
Reconnect the monitor to the power supply and turn it on. Continue charging the
batteries until both capacity indicators are full height and no longer scrolling.
6.
Keep charging for another two hours. After this, check that the orange battery LED in the
front panel is no longer on. If it is, continue charging until it goes off to indicate that the
battery conditioning is complete.

3.1 Measurement principle
3.1.1 CO2 measurement
E-MiniC is a side stream gas analyzer, measuring real time concentrations of CO2. It is a non
dispersive infrared analyzer that measures absorption of the gas sample using an optical
narrow band filter.
The infrared radiation detector is thermopile.
Concentration of CO2 is calculated from absorption measured at 4.2 to 4.3 m.

3.2.1 Gas sampling system
The sampling system draws a gas sample to the analyzer at a fixed rate.
The gas sampling system samples the measured air to the module, and removes water and
impurities from it. A sampling line is connected to the water trap. The pump draws gas through
the sampling line to the gas measuring unit. After the measurement, the gas is exhausted from
the sample gas out connector.
The sample flow is nominally 150 ml/min.
Figure 3
MiniC block diagram
Mini D-fendTM
The sample is drawn through the sampling line. The gas then enters the module through the
water trap, where it is divided into two flows, a main flow and a side flow. The main flow goes
into the analyzer. This flow is separated from the patient side by a hydrophobic filter. The side
flow creates a slight subatmospheric pressure within the Mini D-fend water trap which causes
fluid removed by the hydrophobic filter to collect in the bottle.
Zero valve
The main flow passes through a magnetic valve before proceeding to the analyzer. This valve
is activated to establish the zero point for the MiniC measuring unit. When the valve is
activated, room air is drawn through a filter into the internal system and the gas sensor.

Document no. 2050802-001
Functional description
NafionTM tube 1)
A Nafion tube is used between the water trap and the zero valve to balance the sample gas
humidity with that of ambient air. The tube prevents errors caused by the effect of water vapor
on gas partial pressure when humid gases are measured after calibration with dry gases.
Gas analyzers
After the zero valve and Nafion tube, the gas passes through the miniC measuring unit.
Sample flow differential pressure transducer
The sample flow differential pressure transducer measures pressure drop across a restrictor
and calculates the sample flow from the pressure difference.
Working pressure transducer
The working pressure transducer measures differential pressure between the tubing and
ambient air near the miniC measuring unit.
Atmospheric pressure transducer
The atmospheric pressure transducer measures real-time atmospheric pressure. The following
messages are based on the obtained pressure values: ‘sample line blocked’, ‘check D-fend’,
‘replace D-fend’ and ‘check sample gas outlet’.
Sampling pump and damping chamber
The gas sampling pump is a membrane pump run by a DC-motor. Sample flow is measured
with a differential pressure transducer across a known restriction. The motor is automatically
controlled to maintain a constant flow even when the D-fend water trap ages and starts to get
occluded. It also enables the use of sample tubes with varying lengths and diameters.
NOTE: In no occasion is the flow reversed towards the patient.

3.2.2 MiniC sensor
The miniC sensor is a non-dispersive infrared analyzer measuring absorption of the gas sample
at 4.2 to 4.3 m infrared wavelength, which is selected using an optical narrow band filter. The
IR lamp is a filament surrounded by thermal isolation. There is a hole in the isolation, passing
the radiation to a conical measuring chamber with 3 mm length. From the sample chamber,
the radiation goes into a thermopile detector with an optical filter in front of it.
The temperature sensor measures the miniC measuring unit's temperature and it is used for
temperature compensation.
The miniC sensor is connected to the CPU board and they can’t be replaced separately.

Functional description
3.2.3 CPU board
The CPU board contains a processor, memories and all the analog signal processing needed. A
MiniC measuring unit is attached to the board with a flexible PCB. Also supply voltage and an
RS485 serial channel are connected to the CPU board using another flexible PCB.
Analog signals (CO2, temperature, absolute and differential pressures and lamp current signals)
are fed to the 16-bit A/D converter. The processor controls the A/D converter and calculates
the CO2 percentage and respiration rate from this data.
The processor controls sample flow by adjusting the pump voltage based on the differential
pressure signal. The processor also controls the current of the IR source and keeps it constant.
Calibration data is stored on the EEPROM.

NOTE: Ensure that the calibration gas and regulator are functioning properly before calibration.
Perform the annual maintenance of the regulator as required.
The airway module should be calibrated once every six months or whenever there are
indications of errors in the gas readings.
Calibrate the gas measurement with the Datex-Ohmeda calibration gas. Do not use any other
calibration gases.

Use the regulator 755534.
When you calibrate the E-miniC module, use gas 755580 only and set the O2 concentration to
20%.
Use only recommended calibration gases to guarantee a successful calibration.
During gas calibration, % units are always used for CO2 regardless of selected measuring units.
NOTE: Ensure that the calibration gas and regulator are functioning properly before calibration.
Perform the annual maintenance on the regulator as required.

Turn on the power. For maximum accuracy, let the monitor warm up for 30 minutes. The
menu item Gas calibration remains gray as long as the message ‘Calibrating gas sensor’
is displayed.
4.
Press the Airway Gas key and select Gas calibration.
5.
Wait until the ‘Zero ok’ and then the ‘Feed gas’ messages appear after each gas on the
screen.
6.
Open the regulator and feed calibration gas until the message ‘Adjust’ appears, then
close the valve. If you use an older brass regulator, the feeding pressure should be
adjusted between 5 and 7 psi.
7.
Check that the displayed gas value matches the value on the calibration gas container.
NOTE: When calibrating the E-miniC module, set the O2 level according to the gas, for example
with 755580, set the FiO2 level in the CO2 setup menu to 21-40% and the AIRWAY GAS - CO2
SETUP O2 level to 20%. Adjust the O2 percentage according to the calibration gas (for 755580
the right O2 value is 20%).
NOTE: If an error occurs during calibration or if no gas is fed, the highlighting goes
automatically over the item Recalibrate and the text ‘Calibr. error’ appears. Push the Trim knob
to perform a new calibration.
If adjustments are required:

E-MiniC module disassembly and reassembly
If the message ‘Zero error’ is displayed, press the Normal Screen key and repeat the
calibration procedure.
The time of the last calibration is shown at the bottom of the menu page.
5.2.2 Gas sampling system adjustment
For flow rate measurements, a flow meter with a low flow resistance and the capability to
measure low flow rates is required. A sampling line of normal length has to be connected to the
monitor as it has a considerable effect on the flow.
5.2.3 Flow rate measurement
If any flow rates are not correct, first replace the Mini D-Fend water trap, then recheck the
flows.
The sampling flow rate is measured by a flow meter at the sampling line. The flow rate should
be between 135 and 165 ml/min. The flow rate is adjusted in the Gases service menu with
Sample gain adj.
5.2.4 Flow rate adjustment
NOTE: Before adjusting the sampling flow, make sure there is no leakage in the sampling
system.
Refer to 5.2.5. Gas calibration.
Wait until the Sample Flow value is back to near 150 ml/min.
Connect a flow meter to the 3 meter sampling line and check that the flow (the flow meter
reading) is within the following range:
Sampling flow (ml/min)
135...165
If necessary, readjust the sampling flow:
Select Sample gain adj from the menu.
To increase the sampling flow, turn the Trim knob counterclockwise.
To decrease the flow, turn the Trim knob clockwise.
A change of 0.050 in the Gain value changes the flow approximately 7.5 ml/min.
8-21
Document no. 2050802-001
B40/B20 Patient Monitor
After you have changed the gain, wait until the Sample Flow value on the screen returns near
to the original, then check the flow meter reading again.
5.2.5 Gas calibration
Gas calibration is performed in the Airway Gas menu.
Calibration gas regulator flow check
Interval: every 12 months
Regulator flow specification:
REF 755533 & 755534: 260 – 410 ml/min at 1-10 bar cylinder pressure
REF 755530: 260 – 410ml/min at 5-7psi cylinder pressure
Tools needed: calibration gas can, regulator, piece of silicon hose and flow meter.
Datex-Ohmeda recommends use of TSI 4140 Flow Meter.
Insert the calibration gas regulator on the gas cylinder. Connect a silicon hose between the
regulator and the flow meter. Block the regulator overflow port and open the regulator. Check
the flow rate from the flow meter and verify that the flow is within the specification.

6.2 Gas sampling system troubleshooting
The faults which can occur in the sampling system are: leaks or blockages in the tubing, failure
of the sampling pump or the magnetic valves, or diminishing of the flow rates because of dirt
accumulating in the internal tubing.
The following checks should help in localizing the fault. Whenever suspecting the sampling
system and always after having done any work on the sampling system, check and if
necessary adjust the flow rate.

Troubleshooting
CAUTION
The special internal sample tube is mechanically fragile. Sharp bends will
cause leaks.
NOTE: D-fend water trap should be replaced, when the ‘REPLACE D-FEND’ message appears
during the monitor startup.
NOTE: If any liquid has entered the miniC measuring unit due to water trap filter failure, leave
the module running without a sampling line for several hours and check the functions after it
has dried out.
6.2.1 Sampling system leak test
1.
Connect a flow cassette with a high flow resistance value (50/1.1) to the end of the
sampling line and start following the ‘Amb-Work’ value in the service menu. When the
value exceeds 130 mmHg, connect the other port of the flow cassette to the sample gas
out connector and switch off the pump.
2.
Wait until the pressure inside the sampling system is stabilized, then observe the shown
Amb-Work value. The value, i.e. the pressure inside the sampling system, should not drop
more than 6 mmHg in 20 seconds.
3.
If the pressure drops more, first ensure the connections you have made and repeat the
test.
6.3 MiniC unit troubleshooting

equipment, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.

where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey, a
should be less than the compliance level in each
frequency range. b
Interference may occur in the vicinity of equipment
marked with the following symbol:
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.
a
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
predicated 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 the equipment is used exceeds the applicable RF compliance level above, the
equipment should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the equipment.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
