2Theory of Operation

Integrated Monitor Theory of Operation

The IntelliVue Patient Monitor:

• displays real-time data

• controlls 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.

System Boundaries

The following diagram discusses specific boundaries within the overall system with respect to their openness and real-time requirements:

Philips Clinical Network

2 Theory of Operation Integrated Monitor Theory of Operation

Measurement LAN

combines components of one patient monitor; real time requirements across all interconnected elements

Figure 3 Power Supply Architecture

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 DC. 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.

Data Flow

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

and User

Interface

Data

Acquisition

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 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

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.

2 Theory of Operation Integrated Monitor Theory of Operation

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 cards and automatically connects the I/O board 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.

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:

Integrated Monitor Theory of Operation 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 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).

2 Theory of Operation Integrated Monitor 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 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 an NT 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 monitors route network traffic between the Philips Clinical Network to the internal LAN.

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.

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 R eport

• Tes t Re p or t

• 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.

Integrated Monitor Theory of Operation 2 Theory of Operation

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,

or tcpO2, and Respiration physiological data. The

SpO

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

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.

2 Theory of Operation Integrated 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.

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.

Integrated 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 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.

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, Trim Knob, and PS/2 devices), formats the collected data and sends it to the display and Operating Interface.

tones, operator audible feedback)

2 Theory of Operation Integrated Monitor Theory of Operation

Functional Block Description

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.

3 Testing and Maintenance Tests

Tests

Some of the following testprocedures must be performed in service mode. To enter service mode select

Operating Modes in the main menu. Then select Service Mode and enter the password.

If required, open the screen menu in the monitor info line at the top of the screen and select

Service to access the service screen. This is required particularly for Anesthetic Gas Module testing

procedures.

Visual Test

Inspect the system for obvious signs of damage. Also check external leads and accessories.

The expected test result is pass: the system has no obvious signs of damage.

Power On Test

1 Switch on the monitor and connect the MMS.

2 Observe whether the system boots up successfully and if an ECG wave appears on the screen.

The expected test result is pass: the monitor boots up and displays an ECG wave. The wave might be a flat line if no simulator is attached.

NBP Tests

This section describes NBP test procedures.The monitor must be in service mode to perform these tests.

NBP Accuracy Test

This test checks the performance of the non-invasive blood pressure measurement. Connect the equipment as shown:

Tools required:

• Reference manometer (includes hand pump and valve), accuracy 0.2% of reading.

• Expansion chamber (volume 250 ml +/- 10%)

Expansion Chamber

Tubing

Manometer

• 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.

Tests 3 Testing and Maintenance

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 Clos e Valves off then Cali brate 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.

NBP Leakage Test

The NBP leakage test checks the integrity of the system and of the valve. It is required once per year 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)

5 If the difference is greater than 3 mmHg, calibrate the MMS (see steps 9 to 10 in the accuracy test

procedure).

3 Testing and Maintenance Tests

Valve Test

1 Raise the pressure again to 280 mmHg. 2 Select Close valves: Off.

Barometric Pressure Check and Calibration

Check the barometric pressure value in the sidestream CO2 extension as follows:

1 Go into service mode and select Setup CO

2 Connect a FilterLine to the sidestream CO

Extension.

3 The status line at the bottom of the screen displays “CO2 pressure reading (ambient/cell) xxx/yyy”

where xxx is the ambient pressure and yyy is the measured cell pressure. Check whether the ambient pressure value (x1) matches (within the acceptable tolerance of ±12mm Hg) the reference value you have received. If so, proceed to the leakage check. If the value is not correct, calibrate as follows.

pressure should be approximately 20 mmHg lower than ambient pressure.

3 Testing and Maintenance Tests

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. Do not block the inlet for longer than 25 seconds as this will lead to 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 sidestream CO2 extension as follows:

1 Connect the flowmeter to the CO

2 Check on the flowmeter the flow that the sidestream CO

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.

Tests 3 Testing and Maintenance

When you are satisfied that the flow is set as close as possible to 50 ml per minute, select Store

and confirm the setting. If you do not store the adjusted flow within 60 seconds of the

Flow

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.

After switching the measurement extension on, wait at least 20 minutes before checking the calibration. Check the calibration of the CO

1 Check that the 5% calibration gas and flow regulator are connected.

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

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

9 If not already connected, connect the 5% calibration gas. 10 Select Cal. CO

11 Select the value for the calibration gas. (The default value is 5.0%.)

3 Testing and Maintenance Tests

Open the valve on the calibration gas to allow CO2 gas to flow into the extension. Allow the value

to stabilize before the start of the calibration. Leave the valve open until the instrument gives a prompt that gas can be removed.

13 The extension calibrates and prompts when calibration is successful.

Calibration Verification

1 Reopen the 5% gas valve and allow the value to stabilize.

2 Check that the value displayed on the monitor is correct within the tolerance (see step 2 above).

3 Disconnect the 5% calibration gas and connect the 10% calibration gas.

4 Open the valve on the flow regulator to allow 10% CO

value to stabilize.

5 Check that the value displayed on the monitor is correct within the tolerance (see step 6 above).

If one or both values are not within tolerances, you must exchange the measurement server extension.

Reset Time Counters

You must check the time counters on the sidestream CO2 extension before calibrating the instrument. As well, when parts are replaced, the appropriate counters must be reset to zero.

Tools required:

• Defibrillator with ECG Sync and Marker Output.

• Patient simulator.

1 Connect the patient simulator to the ECG connector on the Measurement server and the

defibrillator to the ECG Sync Output on the monitoring.

2 Set the patient simulator to the following configuration:

– HR = 100 bpm.

– ECG sinus rhythm.

3 Switch the defibrillator to simulation mode.

4 Check that the marker pulse is displayed before the T-wave begins.

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 FMS.

2 Press the Setup key on the front of the VueLink module. 3 In the Setup Vu eL in k menu select Device, then select Test Module. 4 Select Confirm to store the selection and wait for the message “Switched to new device”.

5 Plug in the test module.

6 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.

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

select

Change Wave, then select WAVE.

8 Select the VueLink SmartKey, then select the TEST Plug-In pop-up key

3 Testing and Maintenance Tests

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.

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.

3 Return to monitoring mode.

4 Press the Setup key on the front of the VueLink module and select the required device by selecting

Device in the Setup VueLink menu.

NOTE It is important to ensure that the preselected device drivers are configured exactly the same as they were

before the test, including their default settings.

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.

• 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

• 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.
