2Theory of Operation
Integrated 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
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.

2 Theory of Operation Integrated Monitor Theory of Operation
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 power
needed for the backlights is converted to 12V DC by the backlight 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. The HIF board and the LEDs are supplied with 12V DC unregulated
power. The integrated module slot requires a 5 V supply for the modules slots and uses the 48V and
another DC/DC converter to create 60 V in order to supply power for the modules.
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
Flexible Module Server
CPU
Bank of I/Os
Modules
The CPUs provide two LAN interfaces to interconnect CPUs (via the Internal LAN) or 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.
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.

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 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

2 Theory of Operation Integrated Monitor Theory of Operation
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 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 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, 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, 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.
24
Integrated Monitor Theory of Operation 2 Theory of Operation
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).

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.
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
(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:
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.

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 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.
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.

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.
