Theory of Operation

Monitor Theory of Operation

The IntelliVue MP5/MP5T/MP5SC patient monitor is used for monitoring and recording multiple physiological parameters of adults, pediatrics, and neonates. The monitor also generates alarms for the measured parameters. The monitor is used by trained healthcare professionals in a hospital environment.

The monitor stores data in trend, event, and calculation databases. You can see tabular trends (vital signs) and document them on a printer. You can view measurement trend graphs, with up to three measurements combined in each graph, to help you identify changes in the patient's physiological condition. You can view fast-changing measurement trends with beat to beat resolution and see up to four high resolution trend segments. Event surveillance enhances documentation and review of physiologically significant events by automatically detecting and storing up to 50 user-defined clinical events over a 24 hour period.

The monitor can be configured with various different measurement and interface capabilities. The following comparison table shows in detail the differences between MP5, MP5T and MP5SC:

Power Distribution

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 mainand 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)

•Battery: LAN, Battery Board, mCO2 #J02

•Full: LAN, Battery, MIB/RS232, Video, Nurse Call, mCO2 #J40

•Full USB: LAN, Battery, USB, Video, Nurse Call, mCO2 #J43

Note that WLAN, IIT and MSL Interface require the full system interface board or the Full USB system interface board.

The MP5T is delivered only with the Battery system interface board. The MP5SC is delivered only with a Full USB system interface board.

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.

Compatible Devices (not for MP5T and MP5SC)

IntelliVue G1/G5 Anesthetic Gas Module

Data Flow

The following diagram shows how data is passed through the monitoring system. The individual stages of data flow are explained below.

Data Flow

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 (not for MP5T and MP5SC).

15

2Theory 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 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 and the host monitor, for example:

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

16

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 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 does not support any MMS on the MSL.

Microstream CO2

CO2 sample rate: 20 samples/second Calculation of end tidal CO2 (etCO2):

The M3015A/B MMS Extensions use Microstream® non–dispersive infrared (NDIR) spectroscopy to continuously measure the amount of CO2 during every breath, the amount of CO2 present at the

end of exhalation (etCO2), the amount of CO2 present during inhalation (imCO2), and the respiratory rate. The displayed etCO2 is the maximum etCO2 over the previous peak-picking interval as defined by

the Max Hold setting (configuration mode). It can be set to no peak picking (off), 10 seconds and 20 seconds.

Test method for respiration rate range:

A breath simulator system combined with CO2 and N2 gases was used to simulate respiration rates covering the specified range. The resulting end tidal CO2 values were compared to the expected value. Differences between actual and expected end tidal CO2 values were within the limits of the specified

accuracy for the respective respiration rate, i.e. there was no effect of the respiration rate on the end tidal CO2 values beyond those limits.

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, depending on the monitor model (#J35, #J45, #J47). Switching between wired and wireless networks is automatically triggered by the plugging or unplugging of the network cable.

17

2 Theory of Operation

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.

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.

IntelliVue Patient Monitoring System Functional Block Diagram

19

2 Theory of Operation

Block Diagram Legend

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 parameters and IntelliVue Patient Monitoring
	System software modules. User configuration data is stored in
	a non-volatile 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. Examples of supported reports:
	•	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.

20

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.
Interface Managers

21

2 Theory of Operation

Functional Block	Description
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 parameters 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.
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 or measurement parameters.
	• Sound generation (issues audible alarm signals and
	generates audible information signals, for example QRS
	and SpO2 tones, operator audible feedback)
Interfaces

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	The ECG Out/Marker In interface receives the ECG
(not for MP5T and MP5SC)	waveform directly from the ECG/Resp Arrhythmia ST-
	Segment 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	The Nurse Call board contains a phone jack type connector
(not for MP5T)	with a single close-on-alarm relay.
MIB	The MIB interface allows full-duplex, short-haul
(not for MP5T and MP5SC)	asynchronous binary communication between the monitor
	and an arbitrary (medical/non-medical) device using an eight-
	pin RJ45 modular connector. Communication protocols using
	this interface can be configured.
ECG Sync Out	A pulse signal is provided on the RS-232 interface to allow
(not for MP5T and MP5SC)	synchronisation with other medical devices.
IIT	The built-in IIT adapter allows operation of the MP5
(not for MP5T and MP5SC)	monitors within IntelliVue Instrument Telemetry
	infrastructure.
WLAN	The bulit-in WLAN interface allows wireless operation of the
(not for MP5T)	MP5 monitors with the IntelliVue 802.11 Bedside Adapter.
SRR	The built-in SRR interface allows wireless communication of
	the MP5, MP5T and MP5SC monitors with an IntelliVue
	Instrument Telemetry Transceiver.

23

2 Theory of Operation

Functional Block	Description
MSL	All components of the monitoring system communicate using
(not for MP5T and MP5SC)	an IEEE802.3/ Ethernet LAN in the Measurement Link
	(MSL). This network is used to distribute data between the
	components
USB Interface	The USB interface allows connection of USB devices (Mouse,
(not for MP5T)	Keyboard, Barcode Scanner) to the monitor. Note that USB
	printers are not supported.

Testing and Maintenance

Introduction

This chapter provides a checklist of the testing and maintenance procedures to ensure the performance and safety of the monitor.

These tests must be performed only by qualified personnel certified by the responsible organization. Qualifications required are: training on the subject, knowledge, experience and acquaintance with the relevant technologies, standards and local regulations. The personnel assessing safety must be able to recognize possible consequences and risks arising from non-conforming equipment.

All recurring safety and performance assurance tests must be performed under equal environmental conditions to be comparable.

Preventive Maintenance refers specifically to the series of tests required to make sure the measurement results are accurate. The accuracy and performance procedures are designed to be completed as specified in the following sections or when readings are in question.

For detailed instructions on the maintenance and cleaning of the monitor and its accessories, see Care and Cleaning, Using Batteries and Maintenance and Troubleshooting in the monitor's Instructions for Use.

Terminology and Definitions

The following terms and definitions are used throughout this chapter and taken from the international standards IEC 60601-1, IEC 60601-1-1 and IEC 62353.

•Medical System: a medical electrical system is a combination of at least one medical electrical device and other electrical equipment, interconnected by functional connection or use of a multiple portable socket-outlet.

•Patient Environment: any area in which intentional or unintentional contact can occur between the patient and parts of the medical system or between the patient and other persons who have had contact with parts of the medical system. The patient environment is defined anywhere within 1.5m (5 feet) of the perimeter of the patient's bed and 2.5m (8.2 feet) from the floor.

•Separation Device/Transformer: a component or arrangement of components with input parts and output parts that, for safety reasons, prevent a transfer of unwanted voltage or current between parts of a medical system.

•Multiple Portable Socket-Outlet: a combination of two or more socket-outlets intended to be connected to or integrated with flexible cables or cords, which can easily be moved from one place to another while connected to the power mains.

•Functional Connection: an electrical connection for transfer of signals and/or power.
