2Theory of Operation

Monitor Theory of Operation

The IntelliVue Patient Monitor:

• displays real-time data

• controls the attached measurement servers

• alarms in the case of patient or equipment problems

• offers limited data storage and retrieval (trending)

• interfaces to the Philips Clinical Network and other equipment

2

A monitor with just a single integrated measurement server can be connected to additional building
blocks to form a monitoring system with a large number of measurements, additional interface
capabilities and multiple slave displays. These elements cooperate as one single integrated real-time
measurement system.

System Boundaries

The following diagram discusses specific boundaries within the overall system with respect to their
openness and real-time requirements:

Power Supply

The AC/DC converter transforms the AC power coming from the power plug into 48 V/120W DC
source and isolates the monitoring system from the AC power mains.The 48V is distributed via power
bus and supplies power to all the components of the system: The 56 V DC power needed for the FMS,
MMS and measurement server extension is created by an isolating DC/DC converter. The CPU is
supplied with 3.3 V and 5 V DC power. The transformation is performed in two steps: The first DC/
DC converter is a power regulator which reduces the variations caused by load changes on the 48V
power bus. The second DC/DC converter converts the power to the needed voltage. Interface boards
require a power of 10V AC.

CPU Boards

The CPU boards have an MPC860 50 MHz processor that provides a number of on-chip,
configurable interfaces. An array of 12 fast UARTs with configurable protocol options are
implemented in an ASIC (along with other system functions such as independent watchdogs etc.),
providing interfacing capabilities to measurement modules and I/O boards. The serial interfaces can
easily be electrically isolated. The main board contains additional video hardware.

I/O Boards

Interfaces to the monitor are implemented via I/O boards. The location of these boards is restricted by
general rules. The I/O slot designations diagram and the I/O matrix which outline the I/O board
placement rules can be found in the Installation Instructions section.

The following is a list of Interface (I/O) boards which may be present in your monitor, depending on
your purchased configuration:

•MSL

•Video

• Philips Clinical Network (LAN wired or wireless)

•PS/2

• MIB/RS232

•Flexible Nurse Call

•Parallel printer

• Remote devices (Remote Alarm Device, Remote Extension Device)

The specifications for the above listed interfaces can be found in the technical data sheet for the
monitor and in the Specifications chapter of the Instructions for Use.

Data Acquisition

Monitoring data (for example patient measurement data in the form of waves, numerics and alerts) is
acquired from a variety of sources:

20

Monitor Theory of Operation 2 Theory of Operation

•Measurement Servers

The Measurement Servers connected to the internal LAN convert patient signals to digital data and
apply measurement algorithms to analyze the signals.

• External measurement devices

Data can be also acquired from devices connected to interface boards of the monitor. Software
modules dedicated to such specific devices convert the data received from an external device to the
format used internally. This applies to parameter modules and the Anesthetic Gas Module.

• Server systems on the Philips Clinical Network

To enable networked applications such as the other bed overview, data can be acquired from server
systems attached to the Philips Clinical Network, for example a Philips Information Center.

Data Provider System Service

All data that is acquired from measurement servers or external measurement devices is temporarily
stored by a dedicated data provider system service. All monitor applications use this central service to
access the data in a consistent and synchronized way rather than talking to the interfaces directly.

This service makes the applications independent of the actual type of data acquisition device.

The amount of data stored in the data provider system service varies for the different data types. for
example several seconds of wave forms and the full set of current numerical values are temorarily stored
in RAM.

Persistent Data Storage System Service

Some applications require storage of data over longer periods of time. They can use the persistent data
storage system service. Dependent on the application requirements, this service can store data either in
battery backed-up (buffered) memory or in flash memory. The buffered memory will lose its contents
if the monitor is without power (not connected to mains) for an extended period of time. The flash
memory does not lose its contents.

The trend application for example stores vital signs data in a combination of flash memory and
buffered memory, while the system configuration information (profiles) is kept purely in flash
memory.

Display and User Interface Service

Applications can use high level commands to display monitoring data or status and command windows
on the LCD panel. These commands are interpreted by the display manager application. This
application controls the dedicated video hardware which includes video memory and a special ASIC.

User input is acquired from a variety of input devices, for example the SpeedPoint, the touchscreen or
other standard input devices (keyboard, mouse) which may be attached to I/O boards. The system
software makes sure that the user input is directed to the application which has the operating focus.

Data Output

The monitoring system is very flexible and customizable regarding its data output devices. Built-in
devices (for example LAN, speaker, video) provide the basic output capabilities.

These capabilities can be enhanced by adding additional I/O boards, as required in the specific end­user setup. The additional I/O boards typically provide data to externally attached devices, for example
to printers, RS232 based data collection devices, nurse call systems etc.

21

2 Theory of Operation Monitor Theory of Operation

The monitor can identify I/O boards by means of a serial EEPROM device that stores type and version
information. The operating system detects the I/O boards and automatically connects them with the
associated (interface driver) application. For some multi-purpose cards it is necessary to configure the
card for a particular purpose first (for example the dual MIB/RS232 card can support external touch
display, data import, data export).

Monitor Applications

The monitor applications provide additional system functionality over the basic measurement and
monitoring capabilities. This includes for example trending, report generating, event storage or derived
measurements.

In general, the monitor applications use the data provider system service to access the measurement
data. Application interfaces to the other system services allow the application to visualize data, to store
data over extended periods of time or to output data to other devices.

Internal LAN (Measurement Server Link)

All components of the monitoring system (including measurement servers and CPUs in the monitor)
communicate using an IEEE802.3/ Ethernet LAN in the Measurement Server Link (MSL). This
network is used to distribute data between the components, for example:

• Digitized patient signals including wave data, numerical data and status information (typically from
the measurement server to a display unit)

• Control data representing user interactions (typically from the display unit to a measurement server)

• Shared data structures, for example representing patient demographical data and global
configuration items

The internal LAN allows plug and play configuration of the monitoring system. The system
automatically detects plugging or unplugging of measurement servers and configures the system
accordingly.

The components on the internal LAN are time-synchronized to keep signal data consistent in the
system. Dedicated hardware support for synchronization eliminates any latency of the network driver
software.

The integrated LAN provides deterministic bandwidth allocation/reservation mechanisms so that the
real-time characteristic of signal data and control data exchange is guaranteed. This applies to the data
flow from the measurement server to the monitor (for example measurement signal data) and the data
flow from the monitor to a measurement server (for example to feed data to a recorder module).

Integrated communication hubs in the monitor and the FMS allow flexible cabling options (star
topology, daisy chaining of servers).

Internal

LAN

Philips Clinical Network

The monitoring system may be connected to the Philips Clinical Network, for example to provide
central monitoring capabilities or other network services. This connection may be through a normal
wired connection or through a wireless connection.

The monitor supports the connection of an external off-the-shelf wireless adapter. This allows a simple
field upgrade as well as a technology upgrade in the future. Switching between wired and wireless
networks is automatically triggered by the plugging or unplugging of the network cable.

The Philips Clinical Network protocols function very similarly to the protocols used on the internal
LAN.

MDSE

Internal

LAN

After configuration, the monitoring system sends the digitized patient signals including wave data,
numerical data and status information onto the network. Control data representing user interactions
can be exchanged between the monitoring system and a central station bi-directionally.

Additional protocols are supported for networked applications, for example for the other bed overview
function, which allows viewing of monitoring data from other patients on the network.

For plug and play operation, the monitoring system uses the standard BootP protocol to automatically
acquire a network address.

How does the Support Tool Work with the Monitor

The support tool is a Windows application typically installed on the laptop of a customer engineer or a
biomedical engineer working in the customer’s own service department.

The purpose of the support tool is to upgrade, configure and diagnose all monitoring components

2 Theory of Operation Monitor Theory of Operation

The service protocol developed for this purpose uses a raw access to the devices without the need for IP
addresses etc. over a standard customer network installation, so that even defective devices can be
upgraded as long as the few kBytes of initial boot code are working. The boot code itself can also be
upgraded using the same protocol.

The tool allows access to internal service information and to serial numbers. It can be remote­controlled, for example via a dial-up connection from a response center, provided the proper
infrastructure is in place.

For details see the Instructions for Use for the Support Tool.

Functional Block Description

Services

Operating System The Operating System (OS) provides a layer of isolation between

the specific hardware implementation and the application
software. The OS performs system checks and allocates resources
to ensure safe operation when the system is first started. This
includes internal self-tests on several hardware modules and
configuration checks for validity of configuration with the
operating software. During normal operation, the OS continues
to run checks on system integrity. If error conditions are detected
the OS will halt monitoring operations and inform the operator
about the error condition.

System Services The System Services provide generic common system services.

In particular:
It uses a real-time clock component to track time. It synchronizes
to network time sources and verifies the accuracy of the system
time information. It is also responsible for managing persistent
user configuration data for all Measurement Servers, Flexible
Module Servers and IntelliVue Patient Monitoring System
software modules. User configuration data is stored in a non­volatile read/write storage device

Applications

Reports The Reports Service retrieves current and stored physiological

data and status data to format reports for printing paper
documentation. The following reports are supported:

•Vital Signs Report

• Graphical Trend Report

• Event Review Report

•Event Episode Report

• ECG Report (12 Lead/Multi-Lead)

• Cardiac Output Report

• Calculations Report (Hemodynamic/Oxygenation/
Ventilation)

• Calculations Review Report

•Wedge Report

•Test Report

• Other reports (e.g. Loops, Review Applications, Drug
report)

The Reports service generates report data which can be printed
on a local or a central printer.

26

Monitor Theory of Operation 2 Theory of Operation

Functional Block Description

Record The Record Service retrieves current and stored physiological

data and status data to format a continuous strip recording. A
recording can be triggered manually by the operator or
automatically by an alarm condition. The Record Service uses the
services of the Recorder Interface to control an M1116B
Recorder in the FMS. The Record Service can also send data to a
central recorder.

Alarm The Alarm Service contains logic that prioritizes alarm conditions

that are generated either by the Measurement Servers, Flexible
Module Server, or by IntelliVue Patient Monitoring System
software modules. Visual alarm messages are displayed at the top
of the IntelliVue Patient Monitoring System display and alarm
sounds are generated by a loudspeaker. Alarm conditions may be
generated when a physiological parameter exceeds preselected
alarm limits or when a physiological parameter or any other
software module reports an inoperative status (technical alarm,
for example, the ECG leads may have fallen off the patient). The
Alarm service manages the alarm inactivation states, for example
suspension of alarms, silencing of alarms, and alarm reminder.
Alarm signals may also be configured as latching (alarm signals
are issued until they are acknowledged by the operator, even
when the alarm condition is no longer true). The Alarm service
controls the visual alarm signals (alarm lamps).

Trend The Trend service stores the sample values of physiological data

and status data with a resolution of 12 seconds, 1 minute or 5
minutes for a period of up to 48 hours. The data is kept in
battery buffered read/write storage and flash memory devices to
be preserved across power failures. The stored data is protected
via consistency checks and checksums. When a new patient is
admitted, the trend database erases all data of the previous
patient.

HiRes The OxyCRG (Oxygen CardioRespiroGram) service derives a

high-resolution trend graph from the Beat-to-Beat Heart Rate,
SpO

or tcpO2, and Respiration physiological data. The

2

OxyCRG is specialized for neonatal applications, allowing the
opeartor to identify sudden drops in Heart Rate (Bradycardia)
and SpO

or tcpO2 (Desaturations), and supporting the operator

2

in visualizing Apnea situations.

ADT The ADT (Admit/Discharge/Transmit) service maintains the

patient demographics information. The operator may admit a
new patient, discharge the old patient and enter or modify the
patient demographics. The ADT service also supports the
transport of a patient (trend database) with the M3001A Multi­Measurement Server. The ADT service controls the deletion of
old patient data, the upload of trend data from the M3001A and
the switching back of all settings to user defaults. It also
synchronizes patient information with a central station on the
network.

27

2 Theory of Operation Monitor Theory of Operation

Functional Block Description

Calc Param The Calc Param (Calculated Parameters) service accesses current,

stored and manually entered physiological data as input to
calculation formulas. With these formulas, derived
hemodynamic, oxygenation and ventilation variables are
computed. The calculation results, including the input
parameters, are stored for later review using the Trend service.

Interface Managers

MDSE The MDSE (Medical Data Service Element) Interface Manager is

responsible for the exchange of real-time data between the
IntelliVue Patient Monitoring System display unit and the
Measurement Servers and Flexible Module Server as well as
between the IntelliVue Patient Monitoring System display unit
and other devices attached to the network. MDSE establishes and
maintains a data communication link between the devices. It
provides configuration information about the remote device to
applications in the local device and it allows the exchange of
measurement data and status information between the devices.

Printer The Printer Interface Manager provides a high level interface to a

printer. It provides means to:

• establish a connection to the printer

• transfer data to the printer

• get status of the printer

• close connection to the printer

The Printer Interface Manager also supervises the connection to
the printer and whether the printer accepts data (for example
paper out). The Printer Interface Manager notifies the operator
in such cases.

28

Monitor Theory of Operation 2 Theory of Operation

Functional Block Description

Display & Operator Interface The Display and Operator Interface Manager performs the

following tasks:

• Screen presentation of real-time and stored physiological
measurement data, alarm condition data and status
information received from the MDSE interface manager,
the Alarm service or other IntelliVue Patient Monitoring
System modules

• Screen presentation of operating controls (control
windows)

• Processing of operating control commands received from
HIF Control interface. The module verifies and interprets
the received commands and forwards them to other
software modules of the IntelliVue Patient Monitoring
System display unit, Measurement Servers or Flexible
Module Server

• Sound generation (issues audible alarm signals and
generates audible information signals, for example QRS
and SpO

Interfaces

LAN The LAN interface implements the physical layer of IEEE 802.3.

The LAN interface performs Manchester encoding/decoding,
receive clock recovery, transmit pulse shaping, jabber, link
integrity testing, reverse polarity detection/correction, electrical
isolation, and ESD protection. Electronically separated interfaces
are used for communication to the Measurement Servers or
Flexible Module Server and to the network.

Centronics The Centronics interface implements the standard signaling

method for bi-directional parallel peripheral devices according to
IEEE 1284-I. The interface is used as a parallel interface to a
standard printer with electrical isolation and ESD protection.

Display Controller The Display Controller Interface consists of a video controller

chip, video RAM and the controlling software. The Display
Controller interface processes the high level display commands
(character and graphic generation, wave drawing) and translates
them into pixels, which are written into the video RAM where
the video controller chip generates the video synchronization
signals and the pixel stream for the external display.

HIF Control The HIF (Human Interface Control) interface scans the Human

Interface devices for operator controls (Touch Screen, Trim
Knob, and PS/2 devices), formats the collected data and sends it
to the display and Operating Interface.

2 Theory of Operation Monitor Theory of Operation

Functional Block Description

ECG-Out Marker-In The ECG Out/Marker In interface receives the ECG waveform

directly from the ECG/Resp Arrhythmia ST-Segment
physiological algorithm via an RS-422 serial interface and
converts the digital ECG signal to an analog ECG signal. In
addition, the ECG Out controller receives from a connected
device the marker information and forwards this data to the
ECG/Resp Arrhythmia ST-Segment physiological algorithm.
The converted analog signal is used to synchronize a connected
device to the patient’s ECG

RS-422 The serial link RS-422 interface communicates the ECG signal

to the ECG Output/Marker In of the IntelliVue Patient
Monitoring System display unit. The interface is a serial,
differential, full-duplex link. The interface is ESD protected.

PS/2 The PS/2 interface supports the serial protocol of standard PS/2

devices (mouse). The PS/2 serial protocol is interpreted by the
HIF Control interface.

Remote Device Interface The remote device interface is an interface to the remote alarm

device and the remote extension device. The interface
communicates with the remote devices via a differential serial
link.

Nurse Call The Nurse Call board contains 2 connectors. A phone jack type

connector and a multi-port connector. The phone jack type
connector has a single close-on-alarm relay. The multi-port
connector has three alarm relays which are configurable to be
open or closed on alarm. In addition, this interface has an audible
alert capability for loss of AC power.

MIB The MIB interface allows full-duplex, short-haul asynchronous

binary communication between the monitor and an arbitrary
(medical/non-medical) device using an eight-pin RJ45 modular
connector. Switching between MIB and RS232 protocol is
possible.

tests.

34

Tests 3 Testing and Maintenance

NBP Accuracy Test

This test checks the performance of the non-invasive blood pressure measurement. Connect the
equipment as shown:

Expansion Chamber

Tubing

Manometer

To NBP Input

Tools required:

• Reference manometer (includes hand pump and valve), accuracy 0.2% of reading.

• Expansion chamber (volume 250 ml +/- 10%)

• Appropriate tubing.

In service mode, the systolic and diastolic readings indicate the noise of NBP channels 1 and 2
respectively. When static pressure is applied, the reading in NBP channel 1 should be below 50. The
value in parentheses indicates the actual pressure applied to the system.

1 Connect the manometer and the pump with tubing to the NBP connector on the MMS and to the

expansion chamber.

2 In service mode, select the Setup NBP menu.
3 Select Close Valves: On

4 Raise the pressure to 280 mmHg with the manometer pump.

5 Wait 10 seconds for the measurement to stabilize.

6 Compare the manometer values with the displayed values.

7 Document the value displayed by the monitor (x1).

8 If the difference between the manometer and displayed values is greater than 3 mmHg, calibrate

the MMS. If not, proceed to the leakage test.

9 To calibrate the MMS, select Close Valves off then Cali brate NBP and wait for the

instrument to pump up the expansion chamber.Wait a few seconds after pumping stops until
EnterPrVal is highlighted and then move the cursor to the value shown on the manometer. If
one of the following prompt messages appears during this step, check whether there is leakage in
the setup:

– NBP unable to calibrate – cannot adjust pressure

– NBP unable to calibrate – unstable signal

10 Press Confirm.

If the INOP NBP Equipment Malfunction message occurs in monitoring mode, go back to service
mode and repeat the calibration procedure.

35

3 Testing and Maintenance Tests

NBP Leakage Test

The NBP leakage test checks the integrity of the system and of the valve. It is required once per year
and when you repair the monitor or replace parts.

1 If you have calibrated, repeat steps 2 to 6 from the accuracy test procedure so that you have 280

mmHg pressure on the expansion chamber.

2 Watch the pressure value for 60 seconds.

3 Calculate and document the leakage test value (x2).

x2 = P1 - P2
where P1 is the pressure at the beginning of the leakage test and P2 is the pressure displayed after
60 seconds.
The leakage test value should be less than 6 mmHg.

NBP Linearity Test

1 Reduce the manometer pressure to 150 mmHg.

2 Wait 10 seconds for the measurement to stabilize.

3 After these 10 seconds, compare the manometer value with the displayed value.

4 Document the value displayed by the monitor (x3)

Valve Test

5 If the difference is greater than 3 mmHg, calibrate the MMS (see steps 9 to 10 in the accuracy test

procedure).

1 Raise the pressure again to 280 mmHg.
2 Select Close valves: Off.

3 Wait five seconds and then document the value displayed. The value should be less than 10

mmHg.

4 Document the value displayed by the monitor (x4).

Test Expected test results

Valve Test x4 = value < 10 mmHg

Tests 3 Testing and Maintenance

Sidestream CO2 Performance Test

Allow five seconds between individual service procedures to ensure stable equipment conditions. When
certain monitor procedures are running, service procedures are not possible and trying to start them
will result in a message Service Operation Failed in the monitor’s status line. Wait until
the monitor completes the current operation, then restart the service procedure.

This test checks the performance of the CO

measurement for the sidestream extension. The CO2

2

performance test is required once per year and when the instrument is repaired or when parts are
replaced.

This test uses calibration equipment that you can order (see the Parts section for the part number). The
procedure is summarized in the following steps. Refer to the documentation accompanying the
equipment for detailed instructions.

Tools Required:

• Standard tools, such as screwdriver, tweezers

• Electronic flowmeter, M1026-60144.

• Gas calibration equipment:

• Cal 1 gas 15210-64010 (5% CO

• Cal 2 gas 15210-64020 (10% CO

)

• Cal gas flow regulator M2267A

• Cal tube 13907A

You also need a local barometric pressure rating received from a reliable local source (airport, regional
weather station or hospital weather station) which is located at the same altitude as the hospital.

The CO

calibration for the sidestream extension consists of the following steps:

2

• Barometric pressure check and calibration, if required.

• Leakage check

•Pump check

• Flow check and calibration, if required.

•Noise check

•CO

follows.

Leakage Check

The leakage check consists of checking the tubing between:

• the pump outlet and the measurement server extension outlet and

• the pump inlet and FilterLine inlet.

Check the user’s guide of the flowmeter for details on how to make a correct flow reading.

input to start the pump running.

2

pressure should be approximately 20 mmHg lower than ambient pressure.

4 Connect the flowmeter outlet to the FilterLine inlet using a flexible connecting tube.

5 Block the measurement server extension outlet using your fingertip and observe the flowmeter

display. The value on the flowmeter (x2) should decrease to between 0 and 4 ml/min, accompanied
by an audible increase in pump noise. If the value is within the tolerance limits, continue with part
2 of the leakage check.

6 If the value is outside the tolerance limits, there is a leakage between the pump outlet and the

measurement server extension gas outlet.

7 Open the measurement server extension and check the tubing connections at the pump outlet and

the extension gas outlet. If the connections are good, then there is a leakage in the tubing and you
must exchange the measurement server extension.

Part 2

1 Disconnect the flowmeter from the Part 1 setup and connect the flowmeter inlet to the M3015A

gas outlet.

2 Leave the Filterline connected to the M3015A inlet.

3 Block the inlet of the FilterLine using your fingertip and observe the flowmeter display. The value

on the flowmeter (x3) should decrease to between 0 and 4 ml/min, accompanied by an audible
increase in pump noise. Do not block the inlet for longer than 25 seconds as this will lead to an
“Occlusion” INOP. If the value is within the tolerance limits, there are no leakages and the leakage
check is completed; proceed to the pump check.

38

Tests 3 Testing and Maintenance

If the value is not within the tolerance limits, there is a leakage between the FilterLine inlet and the

4

pump inlet.

5 Check the FilterLine connections and open the M3015A to check the tubing connections at the

pump inlet and the M3015A gas inlet. If the connections are good, try replacing the FilterLine and
repeating the leakage check. If the situation remains, there is a leakage in the tubing and the
M3015A must be exchanged.

Pump Check

1 Connect the flowmeter inlet to the M3015A gas outlet.

2 Connect the FilterLine to the M3015A inlet.

3 Block the inlet of the FilterLine using your fingertip and observe the cell pressure on the M3046A

display. The cell pressure (x4) should be more than 120 mmHg below the ambient pressure shown.
If the pressure difference is less than 120 mmHg, the pump is not strong enough and you should
replace it, irrespective of the Pump OpTime.

Flow Rate Check and Calibration

Check the flow rate in the sidestream CO2 extension as follows:

Noise Check

1 Connect the flowmeter to the CO

2 Check on the flowmeter the flow that the sidestream CO

3 Adjust the flow in the instrument by selecting Increase Flow or Decrease Flow until it

is as close as possible to 50 ml per minute as indicated on the flowmeter gauge.

4 When you are satisfied that the flow is set as close as possible to 50 ml per minute, select Store

Flow and confirm the setting. If you do not store the adjusted flow within 60 seconds of the

adjustment, the old flow setting is restored.

5 If you cannot adjust the flow to within tolerance, replace the pump. If you still cannot make the

flow adjustment, this indicates a fault in the measurement extension, which must be replaced.

1 With the monitor in service mode, select Setup CO

2 Disconnect the flowmeter and connect the 5% calibration gas and flow regulator in its place.

3 Open the valve to apply the 5% calibration gas and wait until the value is stable.

3 Testing and Maintenance Tests

Calculate the expected measurement value in mmHg as follows:

2

0.05 x (ambient pressure) = value mmHg
for example 0.05 x 736 = 36.8 mmHg (with an ambient pressure of 736 mmHg)

3 Open the valve on the flow regulator to allow 5% CO

gas to flow into the extension. Allow the

2

value to stabilize.

4 Check that the value on the instrument (measurement value on the main screen, x7)) matches the

calculated mmHg value ± 2.6 mmHg. If the value is outside the tolerance, calibrate as described in
step 9 in this procedure onwards.

5 Disconnect the 5% calibration gas and connect the 10% calibration gas.

6 Calculate the expected measurement value and tolerance in mmHg as follows:

0.1 x (ambient pressure) = value mmHg
±0.07 x (value mmHg) = tolerance

for example 0.1 x 737 mmHg = 73.7 mmHg (with an ambient pressure of 737 mmHg)
±0.07 x 73.7 mmHg = ±5.16 mmHg tolerance

7 Open the valve on the flow regulator to allow 10% CO

gas to flow into the extension. Allow the

2

value to stabilize.

8 Check that the value on the instrument (x8) matches the calculated mmHg value within the

calculated tolerance. If so, the measurement extension is correctly calibrated. If the value is outside
the tolerance, calibrate as follows.

9 If not already connected, connect the 5% calibration gas.
10 Select Cal. CO

11 Select the value for the calibration gas. (The default value is 5.0%.)

12 Open the valve on the calibration gas to allow CO

to stabilize before the start of the calibration. Leave the valve open until the instrument gives a
prompt that gas can be removed.

13 The extension calibrates and prompts when calibration is successful.

Calibration Verification

1 Reopen the 5% gas valve and allow the value to stabilize.

2 Check that the value displayed on the monitor is correct within the tolerance (see step 2 above).

3 Disconnect the 5% calibration gas and connect the 10% calibration gas.

4 Open the valve on the flow regulator to allow 10% CO

value to stabilize.

5 Check that the value displayed on the monitor is correct within the tolerance (see step 6 above).

If one or both values are not within tolerances, you must exchange the measurement server extension.

Reset Time Counters

You must check the time counters on the sidestream CO2 extension before calibrating the instrument.

VueLink Tests using VueLink Test Module

Use the VueLink plug-in test module ( M1186-60510) to test M1032A VueLink modules.

Test Procedure

You must preselect the test module to ON in Configuration Mode. Therefore, the test module must be
one of the devices made available for selection during configuration of the VueLink module.

Carry out the test itself in monitoring mode. For information concerning the configuration of
VueLink modules see the M1032A VueLink Module Handbook.

1 Plug the VueLink module into the FMS.

2 Press the Setup key on the front of the VueLink module.
3 In the Setup Vu eL in k menu select Device, then select Test Module.
4 Select Confirm to store the selection and wait for the message “Switched to new device”.

5 Plug in the test module.

6 Connect the modules by plugging one end of the cable (part number M1032-61661) into the

connector on the front of the VueLink Module, and the other end into the connector on the front
of the Test Module.

7 Select the wave segment on the screen, where you want the waves to appear. In the wave menu,

select Change Wave, then select WAVE.

8 Select the VueLink SmartKey, then select the TEST Plug-In pop-up key

The test module acts in the same way as an external device would, and sends signals to the VueLink
module in both analog and digital form. The computer module checks these signals for validity, and
then displays “passed” or “failed” on the screen.

The wave segment displays two waveforms, a triangular one and a rectangular one. These are displayed
alternately and for a period of ten seconds each. The expected curve type is indicated below the wave.

There are two pairs of gridlines that indicate the permitted range for the max/min values of these
waves. If all the data received by the test module is correct, the waves will lie within the specified
ranges. If either limit of either wave falls outside the respective gridlines, then the module being tested
is faulty regardless of the passed/failed messages.

When the test is complete:

46

1 Disconnect the cable that joins the test module to the VueLink module.

2 In configuration mode, ensure that the test module is not selected, and the preselected devices are

the same ones as before the test. Also, verify the settings for these devices.

3 Return to monitoring mode.

4 Press the Setup key on the front of the VueLink module and select the required device by selecting

Device in the Setup VueLink menu.

Tests 3 Testing and Maintenance

NOTE

It is important to ensure that the preselected device drivers are configured exactly the same as they were
before the test, including their default settings.

Safety Testing

You are recommended to file the results of safety tests. This may help to identify a problem early
particularly if the test results deteriorate over a period of time.

Warnings, Cautions, and Safety Precautions

• These tests are a proven means of detecting abnormalities that, if undetected, could prove dangerous
to either the patient or the operator.

• You can perform all tests using commercially available Safety Analyzer test equipment. You can
perform basic measurements with widely available multifunction instruments such as the HP 3469A
multimeter or equivalent.

• The consistent use of a Safety Analyzer as a routine step in closing a repair or upgrade is emphasized
as a mandatory step to maintain approval agency status. You can also use the Safety Analyzer as a
troubleshooting tool to detect abnormalities of line voltage and grounding plus total current loads.

• For Europe and Asia/Pacific according to:
IEC60601-1:1988 + A1:1991 + A2:1995 = EN60601-1:1990 +A1:1991 + A2:1995
For USA according to:
UL2601-1

• Additional tests may be required according to local regulations.

•Normally, a Safety Analyzer is used to perform these procedures. Popular testers include the
DEMPSEY 232D, or for use in Europe, testers like the Rigel, Metron or Gerb. Follow the
instructions of the Instrument manufacturer. If the Dempsey is used for an extended length of time,
it could be damaged by the high amp current draw of the system.

• Any device with mains connection that is connected to the medical device must comply with
IEC60601-1 if within patient vicinity and be separately tested at the same intervals as the monitor

Safety Test Procedures

Use the test procedures outlined here only for verifying safe installation or service of the product. The
setups used for these tests and the acceptable ranges of values are derived from local and international
standards but may not be equivalent. These tests are not a substitute for local safety testing where it is
required for an installation or a service event. If using the Metron Safety tester, perform the tests in
accordance with your local regulations, for example in Europe use IEC60601-1/IEC60601-1-1 and in
the US use UL2601-1. The Metron Report should print results with the names listed below, together
with other data.

NOTE For any system with external displays: Disconnect the display from the medical device and perform

S(1) and S(2) on each device with a mains cable. If both pass the tests reconnect the display and
procede with normal use.

Troubleshooting the Individual Measurements or Applications

For problems isolated to an individual parameter or application such as event review, please consult the
Instructions for Use and configuration information.

If the instructions for use did not resolve an individual parameter problem, then another module or
measurement server should be tried.

If you are getting questionable readings for individual measurements you may want to do the
Performance Verification tests in the Testing and Maintenance section.

The performance of the individual applications (event review, arrhythmia, trending) are affected by the
configuration of the monitor. When contacting Philips support you may be asked about the
configuration of the monitor to aid in troubleshooting.
