2 Theory of Operation
Power Distribution
Figure 3 Power Distribution Architecture
The AC/DC converter transforms the AC power (100-240 V AC range) coming from the power plug into a 24 V / 50W DC source and isolates the monitoring system from the AC power mains.
The 24 V DC is distributed via the Interface Board to the optional battery charging circuit and to the main- and recorder board.
13
2 Theory of Operation
If the interface board contains the optional battery circuits, the power is used to charge the battery and
supply the monitoring system. As soon as the AC power source is disconnected, the optional battery
starts and keeps the system powered (battery mode). A DC/DC converter on the interface board
converts the 8-12.6 V DC power supplied by the battery into 15 V DC power, which is distributed to
the monitoring system.
The main board and recorder board contain power supply circuits, which convert the 24 /15 V DC into several voltages supplying the particular components of the monitoring system.
The realtime clock and the buffered RAM is supplied with cont. 3.6 V DC power, provided either by the 24 / 15 V DC system power or by the battery power and converted to 3.6 V DC.
The CPU board has an MPC852/62 MHz processor in the patient monitor 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, video,
etc.), providing interfacing capabilities to integrated measurements and System Interface Boards. The
serial interfaces can easily be electrically isolated. The main board contains additional video hardware.
The CPUs provide a LAN interface to connect to the Philips Clinical Network (Ethernet).
NOTE
An MP5 in companion mode does not receive its power from the host monitor via the MSL. MP5 is always powered by AC power or battery.
System Interfaces
The following is a list of Interface boards which may be present in your monitor, depending on your purchased configuration:
System Interface boards:
• Basic: LAN, Video #J01(no longer orderable)

Data Flow
The following diagram shows how data is passed through the monitoring system. The individual stages of data flow are explained below.
2 Theory of Operation
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 Block
The integrated measurements 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 the IntelliVue G1/G5 Anesthetic Gas Module.
Figure 5 Data Flow
15
2 Theory of Operation
• 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 integrated measurements 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 temporarily 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 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
hardware in the ASIC.
User input is acquired from the touchscreen. The system software makes sure that the user input is directed to the application which has the operating focus.
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 Link)
The MP5/MP5T communicates as a Multi-Measurement Module (MMS) in companion mode when
connected to a host monitor using an IEEE802.3/Ethernet LAN in the Measurement Link (MSL).
This network is used to distribute data between the the MP5/MP5T and the host monitor, for
example:
16
2 Theory of Operation
• 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 on the host monitor 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).
NOTE
The MP5/MP5T does not support any MMS on the MSL.
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 internal wireless adapter (#J35, #J45, #J47). Switching between wired and wireless networks is automatically triggered by the plugging or unplugging of the network cable.
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 in the system over the network.
17
2 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.

Services
Operating System The Operating System (OS) provides a layer of isolation
System Services The System Services provide generic common system
Applications
Reports The Reports Service retrieves current and stored physiological
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.

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 parameters and IntelliVue Patient Monitoring
System software modules. User configuration data is stored in
a non-volatile read/write storage device
data and status data to format reports for printing paper
documentation. Examples of supported reports:
20
• Vital Signs Report
• Graphical Trend Report
• Event Review Report
• Event Episode Report
• ECG Report (12 Lead/Multi-Lead)
•Test Report
The Reports service generates report data which can be printed on 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 a recorder.
The Record Service can also send data to a central recorder.
2 Theory of Operation
Functional Block Description
Alarm The Alarm Service contains logic that prioritizes alarm
conditions that are generated 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).
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.
OxyCRG The OxyCRG (Oxygen CardioRespiroGram) service derives a
high-resolution trend graph from the Beat-to-Beat Heart
Rate, SpO2, and Respiration physiological data. The OxyCRG
is specialized for neonatal applications, allowing the operator
to identify sudden drops in Heart Rate (Bradycardia) and
SpO2 (Desaturation), and supporting the operator 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.
Calc Param The Calc Param (Calculated Parameters) application performs
calculations on physiological numerical values to derive
calculated parameters like Temperature Difference.

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.
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.
following tasks:
Interfaces
• 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 or measurement parameters.
• Sound generation (issues audible alarm signals and generates audible information signals, for example QRS and SpO2 tones, operator audible feedback)
22
2 Theory of Operation
Functional Block Description
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 parameters and to the
network.
Display Controller The Display Controller Interface consists of a video
controller, 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), formats the collected data and sends it to the display
and Operating Interface.
ECG-Out Marker-In (not for MP5T)
The ECG Out/Marker In interface receives the ECG
waveform directly from the ECG/Resp Arrhythmia STSegment physiological algorithm running on the main CPU
and converts the digital ECG signal to an analog ECG signal.
In addition, the ECG Out hardware 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
Nurse Call (not for MP5T)
MIB (not for MP5T)
The Nurse Call board contains a phone jack type connector with a single close-on-alarm relay.
The MIB interface allows full-duplex, short-haul
asynchronous binary communication between the monitor
and an arbitrary (medical/non-medical) device using an eightpin RJ45 modular connector. Communication protocols using
this interface can be configured.
