2Theory of Operation

Monitor Theory of Operation

The IntelliVue MP40/MP50 Patient Monitor:

• displays real-time data

• controls the attached measurement server

• 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

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 one slave display. These elements cooperate as one single integrated real-time
measurement system.

Power Supply

CPU Boards

Figure 7 Power Supply Architecture

The AC/DC converter transforms the AC power coming from the power plug into 14 V/80W DC
source and isolates the monitoring system from the AC power mains.The 14V is distributed via power
bus and supplies power to all the components of the system: The 48V DC power needed for the MMS
and measurement server extension is created by an isolating DC/DC converter. The power needed for
the backlights is converted to 12V DC by the backlight DC/DC converter. The CPU and the non­isolated I/O boards are supplied with 3.3 V and 5 V DC power. Isolated interface boards require a
power of 10V AC. The remote HIF board and the LEDs are supplied with 12V DC power.

The CPU boards have an MPC852/50 MHz processor in the patient monitor and an MPC860/
50MHz in the MMS that provides a number of on-chip, configurable interfaces. An array of 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 System Interface and I/O boards. The serial interfaces can easily be electrically isolated.
The main board contains additional video hardware.

25

2 Theory of Operation Monitor Theory of Operation

IntelliVue Patient Monitor Multi-Measurement Server

CPU Video

The CPUs provide two LAN interfaces to interconnect CPUs (via the MSL) and to connect to the
Philips Clinical Network.

The CPU capabilities are identical. Different loading options are coded on serial EEPROMs to support
the automatic configuration of the operating system at boot time.

System Interface and 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:

Data Flow

of data flow are explained below.

and User

Interface

Data

Provider
Service

Applications

Data Acquisition

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

•Measurement Server

The Measurement Server connected to the internal LAN converts patient signals to digital data and
applies 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

Persistent

Data

Storage

Data

Output

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.

27

2 Theory of Operation Monitor Theory of Operation

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 internal 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 Navigation Point, 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, alarm lamps, 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.

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 (only slave 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:

28

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

Monitor Theory of Operation 2 Theory of Operation

• 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 allow flexible cabling options (star topology, daisy
chaining of servers).

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 wireless adapter or an internal wireless adapter
(#J35). 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.

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.

MDSE Internal LAN

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.

29

2 Theory of Operation Monitor Theory of Operation

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
(modules, measurement servers, and monitors) in the system over the network.

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:
They use a real-time clock component to track time. They
synchronize to network time sources and verify the accuracy of
the system time information. They are 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 non-volatile read/write storage device

Applications

Application Server Client The Application Server Client provides the Citrix1 thin client

functionality.

32

Monitor Theory of Operation 2 Theory of Operation

Functional Block Description

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.

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. 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 signals (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).

33

2 Theory of Operation Monitor Theory of Operation

Functional Block Description

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
operator 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.

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.

Drug Calc The Drug Calc application aids in calculating drug dosages for

patients.

PV Loops The PV Loops application compares graphic representations

of airway waves to help detect changes in the patient airway
condition.

Battery Provides battery operation of the monitor.

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.

34

Monitor Theory of Operation 2 Theory of Operation

Functional Block Description

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.

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.

2 Theory of Operation Monitor Theory of Operation

Functional Block Description

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 Color LCD Display.

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

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

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.

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.

Docking Interface The docking interface provides necessary connections for

docking an MP20/30 or MP40/50 monitor onto the docking
station.

IIT Interface The IIT interface allows operation of the MP20/30/40/50

monitors with IntelliVue Instrument Telemetry.

Preventive Maintenance Procedures 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 Calibrate 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.

41

3 Testing and Maintenance Preventive Maintenance Procedures

NBP Leakage Test

The NBP leakage test checks the integrity of the system and of the valve. It is required once every two
years 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).

Preventive Maintenance Procedures 3 Testing and Maintenance

Microstream 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 Microstream 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 Microstream extension consists of the following steps:

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. The cell pressure shown in the status line on the display should decrease to
between 300 and 500 mmHg. Do not block the inlet for longer than 25 seconds as this will lead to

Preventive Maintenance Procedures 3 Testing and Maintenance

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.

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

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 Microstream CO2 extension as follows:

1 Connect the flowmeter to the CO

2 Check on the flowmeter the flow that the Microstream CO

be 50 ml/min ± 7.5 ml/min. If the value is within tolerance, proceed to the CO
check. If the value is not within tolerance, calibrate as follows.

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.

Noise Check

2 Calculate the expected measurement value in mmHg as follows:

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

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.

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 FMSmodule slot.

2 Press the Setup key on the front of the VueLink module.

3 Press Setup VueLink in the pop-up key area.

4 In the Setup VueLink menu select Device, then select Test Module.

5 Select Confirm to store the selection and wait for the message “Switched to new device”.

6 Plug in the test module.

7 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.

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

select Change Wave, then select WAVE.

9 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.

56

When the test is complete:

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.

point over the wireless link. Place the monitor with the IntelliVue 802.11 Bedside Adapter installed
in close proximity to the access point (e.g. if the access point is mounted on the ceiling, place the
monitor directly below). Wait until the Conn.Status field in the service window shows
Authenticatd (for Rel. C.0 monitors) or Connected (for Rel D.0 or higher). Take the monitor
approximately 5 m away from the access point. There should be no walls or other obstacles
between the monitor and the access point. The following should apply:

– Observe the RSSI (Received Signal Strength Indicator) value for at least 5 - 10 seconds. The

RSSI value wil fluctuate but should stay above 30 in a 5 m distance from the access point used.
The wireless link should be active, i.e. the Conn.Status field should be Authenticatd (for Rel.
C.0 monitors) or Connected (for Rel D.0 or higher), and the other fields should contain values. If
the RSSI value is significantly lower, check the distance to the access point and the antenna
orientation at the monitor. The antenna orientation should be vertical, but the physical
placement of the monitor or other equipment within its vicinity as well as walls or other obstacles
may influence the antenna orientation required to receive the best RSSI value.

5 If this test fails, retry in a different physical area with a different access point.

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.

58

IntelliVue 802.11 Bedside Adapter Communication Test 3 Testing and Maintenance

• 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/UL60601-1

• 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.

• Any device with mains connection that is connected to the medical device must comply with
IEC60601-1-1 if outside patient vicinity and be tested accordingly.

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
proceed with normal use.

3 Testing and Maintenance Battery Handling, Maintenance and Good Practices

Measures patient leakage current from applied Part to earth caused by external main voltage on applied
Part with switch S5 open and closed. Each polarity combination possible is tested using S2 and S6.
This test is applicable for every measurement input .

Battery Handling, Maintenance and Good Practices

This section provides some information on how to handle and maintain the batteries in order to get
the best usage from them. Additionally, some good working practices are also given regarding the
correct disposal of the batteries. This section only applies if a battery board is installed in the monitor.

NOTE The monitor requires two batteries for operation. Both batteries’ charging status should ideally be the

same and should not differ more than 50%.

NOTE If your monitor is connected to an IntelliVue Information Center, you should make sure that the IIC

uses the text catalog revision B.1 or later, otherwise battery INOPs may not display correctly on the
IIC. Consult your IIC documentation for instructions on upgrading the text catalog.

About the Battery

The rechargeable Lithium-Ion batteries used in the monitor are regarded as Smart batteries because
they have built-in circuitry. (This circuitry communicates battery-status information to the Monitor.)

To get the most out of the batteries, observe the following guidelines:

• Condition the batteries only upon maintenance request prompt on display.

• If a battery shows damage or signs of leakage, replace it immediately. Do not use a faulty battery
in the Monitor.

• Capabilities of integrated battery charger: 12.6V, 5 Amps mx.
Actual current / voltage: depends on smart battery request and monitor configuration
The approximate charging time is 4 hours with the monitor switched off and up to 12 hours during
monitor operation, depending on the monitor configuration.

• Battery Disposal—Batteries should be disposed of in an environmentally-responsible manner.
Consult the hospital administrator or your local Philips representative for local arrangements.

Do not dispose of the battery in normal waste containers.

• Battery Storage — Batteries should not remain inside the monitor if they are not used for a longer
period of time. Batteries should be max. 50% charged for storage.

NOTE Batteries will discharge within about 20 days if they are stored inside the monitor without AC power

connection.

Checking the Battery Status

When the Monitor is connected to the AC power supply, the battery charges automatically. The
battery can be charged remotely from the Monitor by using the battery charger. Use only Lithium Ion
battery chargers approved by Philips.

62

Battery status (level of charge) is indicated several ways:

• LED on the front panel of the Monitor.

• Battery gauge.

• Display of battery time below gauge.

Battery Handling, Maintenance and Good Practices 3 Testing and Maintenance

• Battery status window.

• INOP messages.

The AC Power LED is only on when the power cord is connected and AC power is available to the
Monitor. In this case, the battery can be either charging or fully charged.

The battery LED can be green, yellow, or red depending on the following conditions:

less than 10 minutes power
remaining

not enough battery power left to

If only one battery is inserted during charging, the battery LED is yellow during charging and switches
off when the battery is charged.

NOTE If the batteries were charged to 100%, they will not charge again until the charging status goes below

90%.

If the remaining battery-operating time is less than 10 minutes, the LED flashes red at a repetition rate
of approximately 1.5 flashes per second.

When the batteries are empty, the Monitor switches off automatically (including the green On-Off/
Standby LED on the front panel). Attempts to restart the Monitor (by pressing the On-Off/Standby)
causes the red LED to emit a single flash. (The flash may have a delay of up to 2.5 sec after pressing the
On-Off/Standby key). In this case either recharge the batteries (externally or internally) or exchange
the batteries.

NOTE If the batteries become too warm or too cold, they will not begin the recharging cycle until the battery

temperature is within range.

63

3 Testing and Maintenance Battery Handling, Maintenance and Good Practices

Battery Status on the Main Screen

Battery status information can be configured to display
permanently on all Screens. It shows the status of each of the
batteries and the combined battery power and battery time
remaining. These symbols are displayed if a battery board is
installed, no matter whether batteries are inserted or not.

Battery status symbols: These symbols tell you the status of
the batteries detected and which battery compartment they are in, either 1 or 2.

Battery power gauge: This shows the remaining battery power in the combined batteries. It is divided
into sections, each representing 20% of the total power. If three and a half sections are shaded, as in
this example, this indicates that 70% battery power remains. If no batteries are detected, the battery
gauge is greyed out.

Battery malfunction symbols: If a problem is detected with one of the batteries, these symbols
alternate with the battery number to indicate which battery is affected. They may be accompanied by
an INOP message or by a battery status message in the monitor information line (if battery window is
open) providing more details.

Battery Handling, Maintenance and Good Practices 3 Testing and Maintenance

Incompatible Battery: The inserted batteries are checked for certain battery internal parameters. If these
are not correct, the incompatible battery symbol is displayed. Please use only the M4605A batteries
with the MP40/50 monitor. Note that the incompatible battery symbol may also appear if there is a
communication problem between the battery and the battery board.

Temperature outside specified range: The charging of the battery is stopped if the temperature is below

°C or above 50°C in order to protect the battery. Charging is resumed as soon as the temperature is

15
within this range.

Battery Temperature too high: This symbol is displayed if the battery temperature goes above 65°C. In
addition the INOP message CHECK BATT TEMP is displayed. If the battery temperature increases
further above 70°C the batteries will switch off for safety reasons. Allow the batteries to cool down to
avoid the monitor switching off.

Battery is empty: The capacity of the battery is

≤200 mAh. Recharge the battery as soon as possible.

Battery has no power left: Either the battery has switched off power delivery but is still communicating
with the battery board - in this case recharge the battery immediately - or the battery is in deep
discharge, i.e. it has switched off power delivery, has stopped communicating with the battery board
and requires pre-charging to restore communication. The INOP CHARGE BATT 1/ BATT 2 is
issued to indicate that pre-charging is required. To avoid this condition charge batteries to 50% for
storage. Note that the battery malfunction INOP will eventually be issued if the pre-charging does not
restore battery communication within about 10 minutes.

Battery Malfunction:Communication between the battery and the battery board could not be
established within about 10 minutes or battery internal data indicates malfunction. Please see the
“Troubleshooting” section for remedies.

NOTE If both batteries are malfunctioning or incompatible or require pre-charging and the monitor is not

connected to AC power, it will switch off automatically for safety reasons.

65

3 Testing and Maintenance Battery Handling, Maintenance and Good Practices

Battery Status Window

♦ To access the Battery Status window and its associated pop-up keys, select the battery status

information on the Screen, or select Main Setup -> Battery.

Capacity, Remaining tells you how much power is left in each battery.

Capacity, Full Charge tells you how much power each battery can hold when fully charged.

Time To Empty tells you approximately how long you can continue to use the monitor with these

batteries. Note that this time fluctuates depending on the system load (how many measurements and
recordings you carry out), the age of the battery, and the remaining capacity of the battery. The time
indication is blanked after unplugging AC or after changing batteries for about 30 seconds (during
calculation of the Time to Empty)

Time To Full is shown in place of Time To Empty if the monitor is connected to AC power,
and tells you how much time is left until the batteries are charged to 90%. Please allow indication to
stabilize for 3 to 5 minutes after beginning the charging cycle. If batteries are charged over 90%

Batteries Full (>90%) is displayed until they are charged to 100%. Then Batt1/Batt2
Fully Charged is displayed.

Viewing Individual Battery Status

♦ To view information for individual batteries, select the pop-up key Battery 1 or Battery 2.

66

Battery Handling, Maintenance and Good Practices 3 Testing and Maintenance

Documenting Battery Status

To print all battery information in the Battery Status window,

1 Select the battery status information on the Screen or select Main Setup -> Battery to open

the Battery Status window

2 Select the Record Status pop-up key to print the information on a connected recorder

or

Select the Print Status pop-up key to print the information on a connected printer.

Battery Implications

If the batteries are not equally charged and one battery is very low on power the INOP “Battery 1 or 2
empty” may appear. This means that this battery cannot contribute to powering the monitor anymore.
In this case exchange the indicated battery with a charged battery or connect the monitor to AC power
to charge both batteries.

Conditioning a Battery

What is Battery Conditioning?

Battery conditioning recalibrates the battery to ensure that it has accurate information on the actual
battery capacity.

Why is Battery Conditioning Necessary?

The capacity of a battery decreases gradually over the lifetime of a battery. Each time a battery is
charged its capacity decreases slightly. Therefore, the operating time of a monitor running on batteries
also decreases with each charge cycle.

Battery conditioning ensures that the value stored in the battery for its full capacity takes account of
this decrease, so that the remaining battery charge can be calculated accurately, and the low battery
warning given at the right time.

When Should Battery Conditioning be Performed?

Battery conditioning should be performed when indicated by the Battery Status.

67

3 Testing and Maintenance Battery Handling, Maintenance and Good Practices

NOTE When the battery status signals a conditioning request, the displayed Time to Full or Time to

Empty may not be reliable.

What Causes the Conditioning Message on the Monitor?

In addition to the value for the full capacity, the battery also stores a value for the Max Error. The Max
Error tracks the maximum possible deviation of the estimated charge of a battery from the actual
charge.

If a battery is charged or discharged partially, or if it is charged while the monitor is being used, the
accuracy of the “reference points” for the fully discharged and fully charged states decreases, causing an
increase in the value for the Max Error (see diagram, below).

When the Max Error rises over a certain limit, a message is displayed prompting the user to condition
the battery, as described in “Conditioning Batteries” on page 68.

You can reset the value for the Max Error before the battery needs conditioning, by performing the
steps described in”Conditioning Batteries”. The minimum value of the Max Error after conditioning is
2%.

Conditioning Batteries

Battery conditioning can either be performed in the monitor or with an external battery charger.

Battery Conditioning in the Monitor

CAUTION Do not use a monitor being used to monitor patients to condition batteries. The monitor switches off

automatically when the batteries are empty.

68

Touchscreen Calibration 3 Testing and Maintenance

You should condition a battery when its “battery requires maintenance” symbol shows on the Screen.
If conditioning is not performed immediately the monitor will still function according to
specifications. However, the displayed time to empty and time to full will show increasing inaccuracy.
Do not interrupt the charge or discharge cycle during conditioning. To condition a battery,

1 Insert the battery into a monitor connected to mains power.

2 Charge the battery until it is completely full. Switch the monitor off to decrease the charging time

When the battery LED turns green i.e. the batteries are >90% charged, switch on the monitor and
open the Battery Status window. Check that the Batteries fully charged or
Battery 1 / Battery 2 fully charged message is displayed.

3 Disconnect the monitor from mains power, and let the monitor run until the battery is empty and

the monitor switches itself off.

4 Reconnect the monitor to mains power and charge the battery until it is full for use or charge to

50% for storage.

Battery Conditioning with an External Charger

You can use the M8043A Smart Battery Charger for external battery conditioning. For details please
see the IfU for the Smart Battery Charger.

Touchscreen Calibration
