Power Supply
2 Theory of Operation
Main Board
I/O Boards
The AC/DC converter transforms the AC power coming from the plug into 15V/ 70W DC source and isolates the monitoring system from the AC power mains. The 15V is distributed via power bus either directly or over additional converters to all components of the system:
The battery charger is supplied with 15V and switches between AC/DC supply and battery depending on whether AC power cord is plugged or unplugged.
The 48V DC power needed for the MSL is created by an isolating DC/DC converter.
The LED backlight converter located on the panel adapter board is supplied with 9V - 12.6V / 15V.
The isolated interfaces are supplied with 2.5V AC. The main board is supplied with 5V, 3.3V, 1.5V,
1.4V and 1.2V.
Additionally, for some infrastructural functions 3.6V is provided to the main board.
The main board contains the CPU which includes the graphic processing unit and USB controller. The main memory, a system FPGA, a system controller including watchdogs and various power supplies are located on this board. Additionally, this board contains the MSL interface, the recorder interface, the ECG Out hardware and various other interfaces.
System information is stored in serial EEPROMs to support the automatic configuration of the operating system at boot time.
A dual MIB/RS232 board, a Flexible Nurse Call Relay board or an IntelliBridge board can be added optionally.

2 Theory of Operation
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 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.
20
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.
User input is acquired from a variety of input devices, for example the touchscreen or other standard input devices (keyboard, mouse). The system software makes sure that the user input is directed to the application which has the operating focus.
2 Theory of Operation
Data Output
The monitoring system is very flexible and customizable regarding its data output devices. Built-in devices (for example LAN, 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 RS232 based data collection devices.
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 boards it is necessary to configure the board for a particular purpose first (for example the MIB/RS232 board 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 Link)
The monitor and multi-measurement modules 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)
21
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 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).
Philips Clinical Network
The monitoring system may be connected to the Philips Clinical Network, for example to provide central monitoring capabilities or other network services. This connection may be through a normal wired connection or through a wireless connection.
The monitor supports the connection of an internal wireless adapter (#J35). 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.
Ambient Light Sensor
22
The monitor adjusts its display brightness depending on the ambient light level. Therefore an Ambient Light Sensor is integrated in the front bezel of the display.
Although there is an automatic brightness adjustment, it is still possible for the user to change the brightness. As shown in the figure above, the user can select between different brightness level curves.
If a constant brightness is desired, it is possible to deactivate the automatic brightness control via the Config mode of the monitor. Without automatic brightness control, the user can select between different constant brightness levels as shown below.
Microstream CO2
CO2 sample rate: 20 samples/second
2 Theory of Operation
Calculation of end tidial 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.
How does the Support Tool Work with the Monitor
The Support Tool Mark2 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 Mark2 is to upgrade, configure and diagnose all monitoring components (modules, measurement servers, and monitors) in the system over the network.
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 Mark2.

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.

2 Theory of Operation
Functional Block Description
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 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. The following reports are supported:

2 Theory of Operation
Functional Block Description
Alarm The Alarm Service contains logic that prioritizes alarm conditions
Trend The Trend service stores the sample values of physiological data
OxyCRG The OxyCRG (Oxygen CardioRespiroGram) service derives a
ADT The ADT (Admit/Discharge/Transmit) service maintains the
Events The Events Application captures physiological data from episodes
that are generated either by the Measurement Servers 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).
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.
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.
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.
for later review and documentation purposes. Events can be triggered automatically by an alarm condition, by user-defined conditions or manually by the operator.
26
2 Theory of Operation
Functional Block Description
Protocol Watch ProtocolWatch allows the execution of pre-defined clinical
protocols in the IntelliVue patient monitor by combining events such as automatically triggered events, time and manually triggered events with textbook knowledge thus aiding the operator to follow clinical guidelines. ProtocolWatch notifies the operator when certain combinations of clinical conditions occur and it documents the developments and clinician actions in a log which can be reviewed on the monitor and documented on a printer.
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.
Heart Mgr. The Heart Manager Application allows the selection of the
alarming source to be either heart rate (from ECG) or the system pulse rate. The system pulse rate can be chosen from any of the possible pulse rate sources (e.g., SpO2 and invasive pres-sures). The module implements automatic fall-backs when selected signal sources are not available.
Drug Calc The Drug Calc application aids in calculating drug dosages for
patients.

NOTE
It is the responsibility of the facility operator or their designee to obtain reference values for recurring safety and system tests. These reference values are the results of the first test cycles after an installation. You may also purchase this service from Philips.

Testing Sequence

Summary of the recommended sequence of testing:
NOTE
If any single test fails, testing must be discontinued immediately and the device under test must be repaired or labeled as defective.

Visual Inspection

Before Each Use

Check all exterior housings for cracks and damage. Check the condition of all external cables, especially for splits or cracks and signs of twisting. If serious damage is evident, the cable should be replaced immediately. Check that all mountings are correctly installed and secure. Refer to the instructions that accompany the relevant mounting solution.
36

After Each Service, Maintenance or Repair Event

Check:
the integrity of mechanical parts, internally and externally.
any damage or contamination, internally and externally
that no loose parts or foreign bodies remain in the device after servicing or repair.
the integrity of all relevant accessories.

Power On Test

1 Connect the monitoring system to mains and switch it on. This includes connected displays, MMS,
MMS Extensions, X2, and parameter modules, gas analyzers and IntelliBridge devices.
2 Make sure that all steps listed in the table Initial Instrument Boot Phase in the Troubleshooting section
are completed successfully and that 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.

Safety Tests

3 Testing and Maintenance
Safety tests are comprised of the following tests performed on the monitoring system:
protective earth resistance
equipment leakage current
applied part leakage current
system test (if applicable)
Safety test requirements are set according to international standards, their national deviations and specific local requirements. The safety tests detailed in this Service Guide are derived from international standards but may not be sufficient to meet local requirements. We recommend that you 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.
Each individual piece of equipment which has its own connection to mains or which can be connected or disconnected from mains without the use of a tool must be tested individually. The monitoring system as a whole must be tested according to the procedure described in “System Test” on page 52.
Accessories which can affect the safety of the equipment under test or the results of the safety test must be included in the tests and documented.

Warnings, Cautions, and Safety Precautions

These tests are well established procedures of detecting abnormalities that, if undetected, could result in danger to either the patient or the operator.
Disconnect the device under test from the patient before performing safety tests.
Disconnect the device under test from mains before performing safety tests. If this is not possible, ensure that the performance of these tests does not result in danger to the safety analyzer operator, patients or other individuals.
Test equipment (for example, a Safety Analyzer) is required to perform the safety tests. Please refer to Annex C of IEC/EN 62353 for exact requirements for the measurement equipment and for measurement circuits for protective earth resistance and leakage currents. Refer to the
37
3 Testing and Maintenance
documentation that accompanies the test equipment. Only certified technicians should perform safety testing.
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 user and patient safety. You can also use the Safety Analyzer as a troubleshooting tool to detect abnormalities of line voltage and grounding plus total current loads.
During safety testing, mains voltage and electrical currents are applied to the device under test. Ensure that there are no open electrical conductive parts during the performance of these tests. Avoid that users, patients or other individuals come into contact with touch voltage.
For Europe and Asia/Pacific, the monitor complies with: IEC 60601-1:1988 + A1:1991 + A2:1995(Ed.2); EN60601-1:1990 + A1:1993 + A2:1995(Ed.2); IEC 60601-1-1:2001; EN 60601-1-1:2001; IEC 60601-1-2:2001+A1:2004; EN 60601-1­2:2001+A1:2006. For USA, the monitor complies with: UL60601-1:2003 For Canada, CAN/CSA C22.2#601.1-M90+S1+A2
Local regulations supersede the testing requirements listed in this chapter.
If a non-medical electrical device is connected to a medical electrical device, the resulting medical electrical system must comply IEC 60601-1-1:2000/ EN 60601-1-1:2001 or IEC 60601-1:2005/ EN 60601-1:2006+A1:2012 (Ed.3) Section 16 "ME Systems"
Perform safety tests as described on the following pages.

Safety Test Procedures

Use the test procedures outlined here only for verifying and recording the initial values prior to or at installation, safe installation or service of the product, and for periodic recurrent testing. The setups used for these tests and the acceptable ranges of values are derived from local and international standards but may not be equivalent. These tests are not a substitute for local safety testing where it is required for an installation or a service event. If using an approved safety tester, perform the tests in accordance with the information provided by the manufacturer of the tester and in accordance with your local regulations, for example IEC/EN 60601-1, UL60601-1 (US), IEC/EN 62353, and IEC/EN 60601-1-1. The safety tester should print results as detailed in this chapter, together with other data.
Please refer to Annex C of IEC/EN 62353 for requirements for the measurement equipment and for measurement circuits for protective earth resistance and leakage currents.

the integrity of all relevant accessories.
Hints for Correct Performance of Safety Tests
Perform a visual inspection on all detachable power cords used with the monitoring system and include these in all safety test procedures.
Connection lines such as data lines or functional earth conductors may appear to act like protective earth connections. These may lead to incorrect measurements and need to be considered during testing. If necessary, unplug these connections.
During measurements, the device under test shall be isolated from earth (e.g. test on an insulated work bench), except the protective earth conductor in the power supply cord.
Position all cables and cords in such a manner that they do not influence the safety tests.
Measurement of insulation resistance is not required.
When testing a medical electrical system, where possible, test it such that potential ground voltage variations are present as they may be during actual use.
39
3 Testing and Maintenance
Guideline for Performance of Safety Tests
This section introduces the general principle of performing recurrent safety tests. Product specific test descriptions are described in the following sections.
Connect the detachable power cord of the device under test to the safety analyzer's test mains port. Connect the enclosure test lead of the safety analyzer to the enclosure of the device under test, e.g. to the equipotential connector or unearthed conductive accessible parts where applicable during Equipment Leakage Current Tests and Applied Part Leakage Current Tests. For testing the applied part leakage current, connect all applied parts to the safety analyzer using the appropriate patient lead or adapter cable. For the ECG parameter all ten ECG-leads need to be connected to the safety analyzer. If necessary, use an adapter cable to connect all ten ECG-leads. If necessary, repeat the safety test procedure until all available applied parts have been tested. Refer to the documentation that accompanies the safety analyzer for further details on how to set up and perform the test.
Protective Earth Resistance Test - Setup Example
NOTE
The test lead needs to go to parts that require protective earthing. This may be a single connection or several tested after each other
Equipment Leakage Current Test - Setup Example
NOTE
The test lead needs to go to the grounded enclosure parts, the ungrounded enclosure parts and all of the applied parts connected together.

This measures the impedance of the Protective Earth (PE) terminal to all exposed metal parts of the Device under Test (DUT), which are for safety reasons connected to the Protective Earth (PE).
You can find metal parts of the device at the equipotential connector.
Measurements shall be performed using a measuring device capable to deliver a current of at least 200 mA into 500 mOhms with maximum open circuit voltage of 24V
This safety test is based on IEC/EN 62353.
Report the highest value (X1).
Test Expected test results
Protective Earth Resistance Test (with
X1 <= 300mOhms

NOTE
If the protective earth resistance test fails, testing must be discontinued immediately and the device under test must be repaired or labeled as defective.
All values for current and voltage are the root mean square (r.m.s.) values, unless otherwise stated.
Flex the power cord during the protective earth resistance test to evaluate its integrity. If it does not pass the test, exchange the power cord. Then repeat the test. If it still does not pass, follow the instructions in the first bullet point of this note above.
S(2): Equipment Leakage Current Test - Normal Condition
Test to perform:
48
Measuring circuit for the measurement of Equipment Leakage Current - Direct method according to IEC/EN 62353.
This test measures leakage current of accessible conductive and non-conductive metal parts of the monitor and the functional earth leakage current. It tests normal and reversed polarity. Perform the test with S1 closed (Normal Condition).
There are no parts of the equipment that are not protectively earthed. Disconnect any data cables and any connections that may provide an extraneous earth path. Test the device under test (DUT) on an insulated surface. Do not touch the DUT during testing.
This safety test is based on IEC/EN 62353.

In case of an IT-power system, this safety test measurement requires a special measuring circuit, for example with its own integrated TN-system or use of an external isolation transformer attached to the safety test device.
S(3): Equipment Leakage Current Test - Single Fault Condition
Test to perform:
Measuring circuit for the measurement of Equipment Leakage Current - Direct method according to IEC/EN 62353.
This test measures leakage current of accessible conductive and non-conductive metal parts of the monitor and the functional earth leakage current. It tests normal and reversed polarity. Perform the test with S1 open (Single Fault Condition).

3 Testing and Maintenance
In case of an IT-power system, this safety test measurement requires a special measuring circuit, for example with its own integrated TN-system or use of an external isolation transformer attached to the safety test device.
S(4): Applied Part Leakage Current - Mains on Applied Part
NOTE
During measurement of the Applied Part Leakage Current it is possible that the measured current can exceed the allowed limit (per IEC/EN 60601-1 or IEC/EN 62353).
This can occur when the safety tester is connected to the invasive blood pressure and temperature connectors at the same time during the applied leakage current measurement.
The connectors for the invasive blood pressure and temperature are independently functioning connectors.
Although there are individual connectors on the front end, internally those parameters use the same electrical insulation interface and are hardwired to each other. This results in an electrical short of those connectors during measurement if a test current is applied simultaneously. Therefore this should be avoided.
Due to the combined insulation interface, it is sufficient to connect to only one parameter interface (that is, Invasive Blood Pressure or Temperature) of the invasive blood pressure/temperature measurement block. This avoids a short and the potential of exceeding the limit for the current.
Test to perform:
Measuring circuit for the measurement of Applied Part Leakage Current - Direct method according to IEC/EN 62353.
50
3 Testing and Maintenance
This test measures applied part leakage current from applied part to earth caused by external main voltage on the applied part. Each polarity combination possible shall be tested. This test is applicable to each Applied Part tested and results recorded in turn with all other Applied Parts left floating. Applied Parts with multiple connections (e.g. ECG) are tested with the connections short-circuited.
There are no parts of the equipment that are not protectively earthed.
This safety test is based on IEC/EN 62353.
For measurement limits and test voltage, refer to Safety (4) test, Test and Inspection Matrix.
Report the highest value. (X1).
Test Expected test results

3 Testing and Maintenance

System Test

After mounting and setting up a system, perform system safety tests according to IEC/EN 60601-1-1.

What is a Medical Electrical System?

A medical electrical system is a combination of at least one medical electrical piece of equipment and other electrical equipment, interconnected by functional connection or use of a multiple portable socket-outlet.
Devices forming a medical electrical system must comply either with IEC/EN 60601-1-1 or IEC/ EN 60601-1+A1 Ed.3 clause 16.
Any electrical device such as IT equipment that is connected to the medical electrical equipment must comply either with IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16 and be tested accordingly.
Non-medical electrical equipment may require connection through a separating device (e.g. an isolation transformer).

General Requirements for a System

After installation or subsequent modification, a system must comply with the requirements of the system standard IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16. Compliance is checked by inspection, testing or analysis, as specified in the IEC/EN 60601-1-1 or in this book.
Medical electrical equipment must comply with the requirements of the general standard IEC/EN 60601-1, its relevant particular standards and specific national deviations. Non-medical electrical equipment shall comply with IEC safety standards that are relevant to that equipment.
Relevant standards for some non-medical electrical equipment may have limits for equipment leakage currents higher than required by the standard IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16. These higher limits are acceptable only outside the patient environment. It is essential to reduce equipment leakage currents to values specified in IEC/EN 60601-1 when non-medical electrical equipment is to be used within the patient environment.
52

System Example

This illustration shows a system where both the medical electrical equipment and the non-medical electrical equipment are situated at the patient’s bedside.
3 Testing and Maintenance
WARNING
Do not use additional AC mains extension cords or multiple portable socket-outlets. If a multiple portable socket-outlet is used, the resulting system must be compliant with IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16. Do not place multiple socket-outlets on the floor. Do not exceed the maximum permitted load for multiple socket-outlets used with the system. Do not plug additional multiple socket outlets or extension cords into multiple socket outlets or extension cords used within the medical electrical system.
Do not connect any devices that are not supported as part of a system.
Do not use a device in the patient vicinity if it does not comply with IEC/EN 60601-1 or IEC 60601-1 edition 3 clause 16. The whole installation, including devices outside of the patient vicinity, must comply with IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16. Any non­medical device placed and operated in the patient’s vicinity must be powered via a separating transformer (compliant with IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16) that ensures mechanical fixing of the power cords and covering of any unused power outlets.

System Installation Requirements

Ensure that the medical electrical system is installed in a way that the user achieves optimal use.
Make sure the user is informed about the required cleaning, adjustment, sterilization and disinfection procedures listed in the Instructions for Use.
The medical electrical system must be installed in such a way that the user is able to carry out the necessary cleaning, adjustment, sterilization and disinfection procedures listed in the Instructions for Use.
53
3 Testing and Maintenance
Ensure that the medical electrical system is installed in a way that an interruption and restoration of power to any part of the medical electrical system does not result in a safety hazard.
We recommend using fixed mains socket outlets to power the medical system or parts thereof. Avoid using multiple portable socket-outlets.
Any multiple portable socket outlets used must be compliant with IEC 60884-1 and IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16.
Ensure that any part of the system connected to multiple portable socket-outlets is only removable with a tool, i.e. the multiple portable socket-outlet provides a locking mechanism to prevent power cords from being plugged or unplugged unintentionally. Otherwise, the multiple portable socket­outlet must be connected to a separation device. Multiple Socket Outlets used within the medical electrical system must only be used for powering medical electrical equipment which is part of the system.
Ensure that any functional connections between parts of the medical electrical system are isolated by a separation device according to IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16 to limit increased equipment leakage currents caused by current flow through the signal connections where necessary (e.g. leakage current coming from non-medical electrical equipment into medical electrical equipment or building ground voltage differences providing leakage current through grounded data cables). This only works if the equipment leakage current of the respective medical electrical system parts is not exceeded under normal conditions. This isolation is especially important where the non-medical electrical equipment leakage currents can pass to the medical electrical equipment in the system or building ground voltage differences can pass to the medical electrical equipment via ground in a data cable connection in the system
Avoid increase of equipment leakage currents when non-medical electrical equipment within the medical electrical system is used. This only applies when if the equipment leakage current of the respective medical electrical system parts is not exceeded under normal conditions. Use of an additional protective earth connection, separation device or additional non-conductive enclosures are options that can prevent a problem.
Within the patient environment it is important to limit electrical potential differences between different parts of a system. If necessary, use potential equalization equipment (equipotential cable) or additional protective earth connections.
Medical electrical equipment used in medical rooms must be connected to potential equalization equipment (equipotential cable) to avoid electrical potential differences. Check your local requirements for details.

Required Protective Measures at System Installation

For any IT equipment (IEC60950-1) operated in the patient environment ensure that the equipment leakage current does not exceed the limits described in IEC 60601-1. Use a separation device to ensure compliance. After installation of IT equipment in the patient environment, an equipment leakage current test is required.
54
3 Testing and Maintenance
Case 1: Medical Device Combined with Medical Device
If you combine a medical device with another medical device (incl. Philips specified displays) to form a medical electrical system according to IEC/EN 60601-1-1 or IEC/EN 60601-1+A1 Ed.3 clause 16, no additional protective measures are required. The medical electrical devices may be located in or outside the patient vicinity in a medically used room. This is valid as long as the medical devices are connected to separate mains outlets. No system test is required.
NOTE
The pictures below and in the following chapters show the MX800 monitor as an example. All cases apply to the MX400/450/500/550/600/700 monitors as well.

System Test Procedure

If the medical electrical device has already been tested as a standalone device e.g. during factory safety testing, an equipment leakage current test must only be performed once the device is connected to another electrical device/system. If the medical electrical system has not been tested as a standalone device, the device has to be tested as a standalone device (without connection to the system) and as part of the system (with connection to the system).
Connect the detachable power cord of the device under test to the safety analyzer's test mains port. Connect the enclosure test lead of the safety analyzer to the enclosure of the device under test as described in the "Equipment Leakage Test" section . Refer to the documentation that accompanies the safety analyzer for further details on how to set up the test.
Test Expected test results

Equipment Leakage Current Test (Single Fault Condition)
After the testing of the device as a standalone device and as part of the system, check that the resulting values (without connection and with connection to the system) do not differ by more than +/- 10% from each other.
If the devices in the medical electrical system are connected to a multiple portable socket outlet the resulting protective earth leakage current needs to be determined. All system components must be connected to the multiple portable socket outlet and be switched on during this measurement.

Nellcor OxiMax Technology
Accuracy specifications are based on controlled hypoxia studies with healthy non-smoking adult volunteers over the specified saturation SpO2 range(s). Pulse oximeter SpO2 readings were compared to SaO2 values of drawn blood samples measured by hemoximetry. All accuracies are expressed as ± "X" digits. Pulse oximeter equipment measurements are statistically distributed; about two-thirds of pulse oximeter measurements can be expected to fall in this accuracy (ARMS) range. Because scatter and bias of pulse oximeter SpO2 and blood SaO2 comparisons commonly increase as the saturation decreases, and accuracy specifications are calculated from data spanning the stated range, different accuracy values may result when describing partially overlapping ranges.
65
3 Testing and Maintenance
Subjects used to validate SpO2 measurement accuracies were healthy and recruited from the local population. Comprised of both men and women, subjects spanned a range of skin pigmentations and ranged in age from 18-50 years old.
Oxygen saturation accuracy can be affected by certain environmental, equipment, and patient physiologic conditions (as discussed in the Instructions for Use for the monitor) that influence readings of SpO2, SaO2, or both. Accordingly, observations of clinical accuracy may not achieve the same levels as those obtained under controlled laboratory conditions.
Pulse rate accuracy has been validated with an electronic pulse simulator.
Masimo SET SpO2 Technology
The SpO2 accuracy (except for LNOP Blue sensors) has been validated in human studies against arterial blood sample reference measured with a CO-oximeter. In a controlled desaturation study, healthy adult volunteers with saturation levels between 70% and 100% SpO2 were studied.
The population characteristics for those studies were:
healthy female subjects: 22 to 39 years of age; light to dark skin pigmentation
healthy male subjects: 19 to 37 years of age; light to dark skin pigmentation
The LNOP Blue SpO2 accuracy has been validated in human blood studies on neonatal, infant and pediatric patients with congenital cyanotic cardiac lesions in the range of 60%-100% SpO2 against a laboratory CO-oximeter.
The population characteristics for those studies were:
female patients: 5 days to 20 months of age; light and dark skin pigmentation
male patients: 1 day to 13 months of age; light and dark skin pigmentation
Pulse rate accuracy has been validated with an electronic pulse simulator or ECG as reference.

3 Testing and Maintenance
Tools required:
Reference manometer (includes hand pump and valve), accuracy +/-0.8mmHg.
Expansion chamber (volume 250 ml +/- 10%)
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.
1 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 or if the
NBP pump assembly has been exchanged, calibrate the MMS. If not, proceed to the leakage test.
9 To calibrate the MMS, select Close Valves off then Calibrate NBP and wait for the instrument to
pump up the expansion chamber.Wait a few seconds after pumping stops until 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 every two years and when you repair the MMS or X2 or replace parts.

Barometric Pressure Check and Calibration
NOTE
The M3015A with HW Rev C and the M3015B do not require calibration of the barometric pressure. Therefore you will not be able to activate a barometric pressure calibration. If you are using a HW Rev C M3015A or M3015B, perform the barometric pressure check as described below, making sure that only a sample line is connected to the MMS Extension. If the pressure check fails, the M3015A/B needs to be exchanged.
Check the barometric pressure value in the M3015A/B MMS Extension or the MP5 as follows:
1 Go into service mode and select Setup CO

Battery Handling, Maintenance and Good Practices

This section provides some information on how to handle and maintain the battery in order to get the best usage from it. Additionally, some good working practices are also given regarding the correct disposal of the batteries.

Battery Care

Battery care begins when you receive a new battery and continues throughout the life of the battery. The table below lists battery care activities and when they should be performed.
Activity When to Perform

3 Testing and Maintenance

Handling Precautions

Lithium ion batteries store a large amount of energy in a small package.Use caution when handling the batteries; misuse or abuse could cause bodily injury and/or property damage.
Do not short circuit - take care that the terminals do not contact metal or other conductive materials during transport and storage
Do not crush, drop or puncture - mechanical abuse can lead to internal damage and internal short circuits which may not be visible externally
Do not apply reverse polarity
Do not expose batteries to liquids
Do not incinerate batteries or expose them to temperatures above 60°C (140°F)
Do not attempt to disassemble a battery.
If a battery has been dropped or banged against a hard surface, whether damage is visible externally or not:
discontinue use
dispose of the battery in accordance with the disposal instructions
If a battery shows damage or signs of leakage, replace it immediately. Do not use a faulty battery in the monitor.

Storage

When storing batteries, make sure that the battery terminals do not come into contact with metallic objects, or other conductive materials.
If batteries are stored for an extended period of time, they should be stored in a cool place, ideally at 15°C (60°F), with a state of charge of 20% to 40%. Storing batteries in a cool place slows the aging process.
The batteries should not be stored at a temperature outside the range of -20°C (-4°F) to 60°C (140°F).
Do not store batteries in direct sunlight.
Stored batteries should be partially charged to 20% to 40% of their capacity every 6 months. They should be charged to full capacity prior to use.
NOTE
Storing batteries at temperatures above 38°C (100°F) for extended periods of time could significantly reduce the batteries’ life expectancy.

Battery Lifetime Management

The lifetime of a Lithium Ion battery depends on the frequency and duration of use. When properly cared for, the useful life is approximately 3 years or 500 charge-discharge cycles, whichever comes first. In addition, experience indicates that the incidence of failure may increase with battery service life due to the accumulated stresses of daily use. We therefore strongly recommend that lithium ion batteries be replaced after 3 years or 500 charge-discharge cycles.
96
The age of a lithium ion battery begins at the date of manufacture. To see the date of manufacture and the number of charge-discharge cycles, select the battery symbol on the patient monitor screen.
The date of manufacture and the number of charge-discharge cycles are listed with other battery data on the screen.
WARNING
The risk of battery failure increases with age, when a battery remains in use longer than 3 years or 500 charge-discharge cycles. Such failures can result in overheating that in rare cases can cause the battery to ignite or explode.

Disposal

Batteries should be disposed of in an environmentally-responsible manner. Consult the hospital administrator or your local Philips representative for local arrangements.
Discharge the batteries and insulate the terminals with tape before disposal. Dispose of used batteries promptly and in accordance with local recycling regulations.

About the Battery

The rechargeable Lithium-Ion batteries used in the monitor are regarded as Smart batteries because they have built-in circuitry. (This circuitry communicates battery status information to the monitor.)
Actual current/voltage: depends on smart battery request and monitor configuration. The approximate charging time is 3 hours with the monitor switched off and up to 5 hours during monitor operation, depending on the monitor configuration.
3 Testing and Maintenance
NOTE
Batteries will discharge within about 20 days if they are stored inside the monitor without AC power connection.

Checking the Battery Status

When the Monitor is connected to the AC power supply, the battery charges automatically. The battery can be charged remotely from the Monitor by using the battery charger. Use only the 865432 Smart battery conditioner.
Battery status (level of charge) is indicated in several ways:
LED on the front panel of the Monitor.
Battery gauge.
Display of battery time below gauge.
Battery status window.
INOP messages.
The AC Power LED is only on when the power cord is connected and AC power is available to the Monitor. In this case, the battery can be either charging or fully charged.
The battery LED can be green, yellow, or red depending on the following conditions:
Battery LED Colors If the monitor is connected to
AC power, this means
If the monitor is running on battery power, this means
Green

Battery Status on the Main Screen

Battery status information can be configured to display permanently on all Screens. It shows the status of the battery and the battery power and battery time remaining. The battery time is only displayed when the monitor is not running on AC power. Note that the battery status information may take a few minutes after the monitor is switched on to stabilize and show correct values.
If the monitor is running on battery power, this means
10 minutes power remaining
not enough battery power left to power monitor
Battery power gauge:
This shows the remaining battery power. It is divided into sections, each representing 20% of the total power. If three and a half sections are shaded, as in this example, this indicates that 70% battery power remains. If no battery is detected, the battery gauge is greyed out.
Battery malfunction symbols:
If a problem is detected with the battery, these symbols are displayed. They may be accompanied by an INOP message or by a battery status message in the monitor information line (if battery window is open) providing more details.
Battery Status Symbols
Battery requires maintenance
Battery is empty
Battery not charging as the temperature is above or below the specified range
Charging stopped to protect the battery

Battery Malfunction Symbols
Incompatible Battery
3 Testing and Maintenance
Battery Malfunction
Battery temperature too high
Battery has no power left
Explanations of Battery Status and Malfunction Symbols:
Battery requires maintenance: The battery requires conditioning. Refer to “Conditioning Batteries” for details.
Battery is empty: The capacity of the battery is 10 min. Recharge the battery as soon as possible.
Temperature outside specified range: The charging of the battery is stopped if the temperature is below 15°C
or above 50°C in order to protect the battery. Charging is resumed as soon as the temperature is within this range.
Incompatible Battery: The inserted battery is checked for certain battery internal parameters. If these are not correct, the incompatible battery symbol is displayed. Please use only M4605A batteries with the MX400/450/500/550 monitor. Note that the incompatible battery symbol may also appear if there is a communication problem between the battery and the Standard System Interface board.
Battery Malfunction:Communication between the battery and the Standard System Interface board could not be established or battery internal data indicates malfunction. Please see the “Troubleshooting” section for remedies.
Battery Temperature too high: This symbol is displayed if the battery temperature goes above 65°C. In addition the INOP message CHECK BATT TEMP is displayed. If the battery temperature increases further above 70°C the batteries will switch off for safety reasons. Allow the battery to cool down to avoid the monitor switching off.
Battery has no power left: If the monitor is not running on AC power: battery will switch off power delivery at any moment - in this case recharge the battery immediately - or, if the monitor is running on AC power, the battery is in deep discharge and requires pre-charging to restore communication. To avoid this condition charge batteries to 50% for storage. Note that the battery malfunction INOP will eventually be issued if the pre-charging does not restore battery communication within about 4 minutes.

Conditioning a Battery

What is Battery Conditioning?
Battery conditioning recalibrates the battery to ensure that it has accurate information on the actual battery capacity.
Why is Battery Conditioning Necessary?
The capacity of a battery decreases gradually over the lifetime of a battery. Each time a battery is charged its capacity decreases slightly. Therefore, the operating time of a monitor running on batteries also decreases with each charge cycle.
Battery Full (>90%) is
Batt Fully Charged is displayed.
