2 Theory of Operation Monitor Theory of Operation
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 MMS 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 or MPC86x 100 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.
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.
Monitor Theory of Operation 2 Theory of Operation
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 (analog)
- Philips Clinical Network (LAN wired or wireless)
- Basic Alarm Relay (Nurse Call)
I/O boards:
- PS/2
- MIB/RS232
- USB

Data Flow

- Flexible Nurse Call
- Parallel printer
- Remote devices (Remote Alarm Device, Remote Extension Device)
- IntelliVue 802.11 Bedside Adapter
The specifications for the above listed interfaces can be found in the technical data sheet for the monitor and in the Installation and Specifications chapter of the Instructions for Use.
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 Monitor 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 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.
Monitor Theory of Operation 2 Theory of Operation
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 end-user 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.
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.
2 Theory of Operation Monitor Theory of Operation
Internal LAN (Measurement 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 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).
Monitor Theory of Operation 2 Theory of Operation
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.
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 componen ts (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.

Block Diagram Legend

Functional Block Description
Services Operating System The Operating System (OS) provides a layer of isolation
between the specific hardware implem entati on an d 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 Racks 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.
2 Theory of Operation Monitor 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 in the FMS. The Record Service can also send data to a central recorder.
Monitor Theory of Operation 2 Theory of Operation
Functional Block Description
Alarm The Alarm Service contains logic that prioritizes alarm
conditions that are generated either by the Measurement Servers, Flexible Module Rack, 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, SpO2 or tcpO2, and Respiration physiological data. The OxyCRG is specialized for neonatal applications, allowing the operator to identify sudden drops in Heart Rate (Bradycardia) and SpO2 or tcpO2 (Desaturations), 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. The ADT service also supports the transport of a patient (trend database) with the M3001A Multi-Measurement Module. 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.
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.
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. 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
Rack 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.
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 Rack
- Sound generation (issues audible alarm signals and
generates audible information signals, for example QRS and SpO2 tones, operator audible feedback)
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 Rack 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.

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, USB 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.
