1 Introduction Features and Capabilities

Features and Capabilities

The HeartStart MRx is a lightweight, portable, monitor/defibrillator. It provides four modes of operation: Monitor, Manual Defib, AED, and Pacer (optional).

In Monitor Mode you can monitor up to four ECG waveforms, acquired through a 3-, 5-, or 10-lead ECG set or multifunction electrode pads. Optional monitoring of pulse oximetry (SpO pressure (IP), non-invasive blood pressure (NBP), temperature (Temp), and carbon dioxide (EtCO are also available. Measurements from these parameters are presented on the display and alarms are available to alert you to changes in the patient’s condition.

Monitor Mode also provides an optional 12-Lead ECG function, enabling you to preview, acquire, store, transmit, and print 12-lead ECG reports, with or without analysis/interpretation.

Manual Defib Mode offers simple, 3-step defibrillation. You analyze the patient’s ECG and, if appropriate: 1) select an energy setting, 2) charge, and 3) deliver the shock. Defibrillation may be performed using paddles or multifunction electrode pads. Manual Defib Mode also allows you to perform synchronized cardioversion and internal defibrillation.

In AED Mode, the HeartStart MRx analyzes the patient’s ECG and determines whether a shock is advised. Voice prompts guide you through the 3-step defibrillation process, providing easy-to-follow instructions and patient information. Voice prompts are reinforced by messages that appear on the display.

), invasive

)

Both Manual Defib and AED Mode incorporate the Philips’ low energy SMART Biphasic waveform for defibrillation, Q-CPR, and audio recording.

Optional Pacer Mode offers non-invasive transcutaneous pacing therapy. Pace pulses are delivered through multifunction electrode pads, using a monophasic waveform.

The HeartStart MRx is powered by rechargeable lithium ion batteries. Available battery power is easily determined by viewing the convenient battery power indicators located on the device display or by checking the indicators on the battery itself. Additionally, an external AC or DC power supply may be applied as a secondary power source and for continual battery charging.

The HeartStart MRx performs Automated Tests on a regular basis. The status of the device’s critical functions are reported to the Ready For Use (RFU) indicator. Prominently displayed, the RFU indicator communicates the status of your device, letting you know if it is operating correctly, needs attention, or is unable to deliver therapy. In addition, performing the specified Operational Check ensures that the HeartStart MRx is functioning properly.

The HeartStart MRx M3535 model with the IntelliVue Networking Option (available in the USA only) can connect to the Philips IntelliVue Clinical Network.

The HeartStart MRx automatically stores critical event and trend data in its internal memory, such as Event Summaries and 12-Lead Reports. The HeartStart MRx also enables you to copy data and event information to an optional external data card for downloading to Philips’ data management solution, HeartStart Event Review Pro, as well as transfer data using Bluetooth be transferred using Rosetta-Lt™.

The HeartStart MRx is highly configurable to better meet the needs of diverse users. Be sure to familiarize yourself with the device’s configuration before using the HeartStart MRx.

2Maintenance Checking the NBP Module

Check the Status Displays

1 Check the cycle counter.

Check the number of measurement cycles shown on the screen. If the NBP module has executed more than 50,000 cycles, replacement is recommended. See “NBP Module” on page 164 for instructions on replacing the NBP module.

Following replacement, run the required Performance Verification and Safety Tests (see “Required

Testing Levels” on page 196).

2 Check the calibration status.

If the screen indicates that calibration is recommended, perform all of the actions described in this chapter, beginning with “Test the Accuracy”. The calibration status is automatically reset at the successful completion of a calibration.

NBP Safety Timeout

Do not keep the cuff pressurized for more than 3 minutes. The NBP module times out if the pressure remains greater than 10 mmHg for 3 minutes. The NBP module overpressure occurs when the cuff pressure exceeds 300 mmHg. In both cases, the valve opens, and the pressure drops. To reset the module, press the [Main Service] softkey and then access the NBP Service screen again to start the calibration.

Test the Accuracy

1 Connect the NBP tubing to the NBP port on the monitor/defibrillator, and connect the test

manometer and expansion chamber to the tubing. See Figure 10.

Test for Leaks

1 Pressurize the expansion chamber to approximately 250 mmHg.

2 Wait for 30 seconds to allow the pressure in the unit to equalize.

3 Watch the displayed pressure for 60 seconds.

4 At the end of this 60 seconds record the pressure drop. Any pressure drop observed should be

6 mmHg.

5 If the pressure decreases by more than 6 mmHg, there is a leak. Replace the NBP tubing and cuff

and try the leakage test again. If the pressure still decreases by more than 6 mmHg, begin troubleshooting and repairing the device as needed.

6 Release the pressure in the cuff before proceeding to the next test to avoid the safety timeout.

Test the Linearity

1 Pressurize the expansion chamber to approximately 150 mmHg.

2 When the pressure is stabilized, compare the displayed pressure reading to the pressure indicated

by the manometer.

If the difference between the manometer and the displayed pressure is >±2 mmHg, perform the steps in “Calibrate the NBP Measurement”. Then repeat this linearity test.

Calibrate the NBP Measurement

NOTE If the error message “Calibration failed. Check that the pressure applied is correct. Please restart

calibration.” appears after entering either calibration point, then re-start the calibration.

Pressing the [Calibrate] softkey starts the calibration process. You must complete the calibration process within three minutes or the NBP module times out and will be out of calibration.

1 Press the [Calibrate] softkey.

The message “Apply 0 mmHg. Select Next when ready” is displayed.

2 Release all of the pressure in the expansion chamber so that the manometer reads 0 mmHg.

Inlet Leakage Check Setup

If this reading is incorrect (>4 ml/min. flow) it indicates a leak in the line between the FilterLine inlet and the pump inlet. Begin troubleshooting and repairing the device as needed. See

“Troubleshooting” on page 27.

2Maintenance Checking the CO2 Module

Pump Check

This test checks the ‘strength’ of the pump by occluding the inlet and measuring how deep a vacuum the pump can pull.

NOTE These tests must be conducted in this order. For example, if you perform the Pump Check, and there is

a leak that you have not found because you did not perform the leak tests, it may appear that the device has a faulty pump, when in fact it has a loose tubing connection.

1 From the CO

2 Follow the instructions on the screen to perform the pump check.

3 The difference between the cell and ambient pressures displayed should be more than 120 mmHg.

Service menu, select Pump Check.

If the pressure reading is correct (difference >120 mmHg), the device passes the pump test.

If the pressure reading is incorrect, it indicates the pump is defective (regardless of the number of hours it has run) and the CO

module must be replaced. See “CO2 Module” on page 166.

Flow Rate Check

1 Disconnect the tubing from the flowmeter inlet.

2 From the CO

3 Connect the FilterLine to the flowmeter outlet.

4 Follow the instructions on the screen to perform the Flow Rate check.

NOTE Be sure there are no kinks, pinches, or obstructions in any of the tubing — this can create a

restriction that will diminish the flow rate and cause a false failure of this test.

5 If the flow rate is within the tolerance limit (50 ± 7.5 ml/min), the test passes.

If the flow rate is not within the tolerance limit, proceed to “CO2 Calibration” on page 25 to calibrate the flow rate.

6 Use the Navigation buttons to increase and decrease the flow until it is as close as possible to 50 ml

per minute as indicated on the flowmeter gauge.

Service menu, select Flow Rate Check.

7 When you are satisfied that the flow is set as close as possible to 50 ml, press the [Store Flow]

softkey to confirm the setting. If the adjusted flow is not stored within 60 seconds of the adjustment, the old flow setting is restored.

3 Troubleshooting Ready For Use Indicator

Ready For Use Indicator

The Ready For Use (RFU) indicator, located in the upper right corner of the device, reports the status of critical functions of the device as determined by the Automated tests. These Automated tests run periodically while the device is turned off (but has a power source) and check the following critical functions of the device:

• defibrillation and cardioversion

•pacing

• pads/paddles ECG

• 3-lead/5-lead/12-lead ECG

• battery

The RFU indicator also reports failures in critical functions detected at run time, during an Operational Check, and during Service Mode tests. Always check the RFU indicator when troubleshooting the device.

Automated test failures of non-critical components (such as the NBP, SpO modules) are not reflected in the RFU indicator, but are reported through inops when the device is turned on.

The RFU indicator displays the status of the device using the following definitions.

3 Troubleshooting Shift Checklist and Operational Check

Shift Checklist and Operational Check

In order to help ensure that defibrillators are ready for use when needed, the American Heart Association (AHA) recommends that users complete a check list, often referred to as a shift check, at the beginning of each change in personnel. The activities on this check list include verifying that the appropriate supplies and accessories are present, the device is plugged in, has sufficient battery power, and is ready for use. Philips Medical Systems supports the AHA check list recommendations and has provided a Shift Checklist document with the HeartStart MRx.

Weekly Shock Test

In addition to the shift check, you must verify the ability to deliver defibrillation therapy once a week by performing one of the following

• Operational Check (see “Operational Check for Version B.05 or Greater” on page 41 or

“Operational Check for Versions Prior to B.05” on page 35).

• Weekly Shock Test (see the instructions below).

NOTE Test reusable sterilizable paddles (internal or external) prior to each use. See the Sterilizable

Defibrillator Paddles, Instructions for Use for more information.

To perform the Weekly Shock Test:

1 If you are using paddles, make sure the paddles are secure in their pockets and that the Patient

Contact Indicator (PCI) LEDs located on the sternum paddle are not lit. If the LEDs light, adjust the paddles in their pockets. If the LEDs continue to light, clean both the adult and pediatric paddle electrode surfaces.

If you are using multifunction electrode pads, attach a test load to the end of the patient Therapy cable.

2 Turn the Therapy knob to 150 J.

3 Press the Charge button.

NOTE If it becomes necessary to disarm the defibrillator, press [Disarm] softkey.

4 The strip prints if configured to do so. If the strip does not print immediately, press the Print

button.

5 If using:

– Pads, then press the Shock button on the HeartStart MRx to deliver a shock into the test load.

– External paddles, then simultaneously press the shock buttons located on the paddles to deliver a

shock into the pockets.

6 Confirm on the printed strip that the energy delivered to the test load is 150 J + 23 J (127 J to

173 J). If not, take the device out of use and begin troubleshooting.

Shift Checklist and Operational Check 3 Troubleshooting

Operational Check for Versions Prior to B.05

Modifications were made to the Operational Check with software version B.05. If your device is running software prior to B.05, refer to this section for an explanation of the Operational Check procedure. If your device is running software version B.05 or greater, refer to “Operational Check for

Version B.05 or Greater” on page 41.

NOTE To determine the device’s software version, select Other > Print Device Info from the Main menu.

Operational Checks should be performed at regular intervals to supplement the hourly, daily, and weekly Automated Tests executed by the HeartStart MRx. Automated Tests provide adequate assurance that the device is in a functional state of readiness. Operational Checks supplement the Automated Tests by verifying therapy cables, the ECG cable, paddles, audio, and display functionality, along with replicating the Weekly test. Operational Checks also notify you if the battery, NBP module, or CO

At completion of the Operational Check, the message Operational Check Passed is displayed if all of the tests pass. If any test fails, the message Non-Critical Failure, Critical Failure, or Battery Failure is displayed, depending upon the severity of the failed functionality. You must fix the problem and successfully run the Operational Check to clear the failure.

Keep in mind the following points about the Operational Check:

• You can run Operational Check from the Other menu in Monitor Mode or from the Service Mode

module need calibration.

Main menu – the Operational Check is the same in both modes. When you exit the Operational Check from Service Mode, you are returned to Monitor Mode.

• The Operational Check runs the Defib test on battery power to reflect typical operating conditions for defibrillation. The device automatically disconnects AC/DC power.

• Perform the Defib Test for each type of patient Therapy cable used on the device (multifunction defib pads or external paddles). At the conclusion of the Defib Test, you can attach another Therapy cable and repeat the test.

NOTE If theHeartStart MRx is equipped with multifunction defib pads only and does not have a paddle tray,

you cannot test paddles during an Operational Check. To test the paddles, you must have a test load. Run the Weekly Shock Test, delivering the shock into the test load. (See “Weekly Shock Test” on

page 34 for details.)

• Options that are not installed on the device do not appear on the screen or printed report.

•The message In Progress is displayed as each test is run. The test result (pass or fail) is displayed at the completion of each test. (See Ta b le 5 on page 37 for a full explanation of each test.)

• Use the test results to troubleshoot and repair the device.

• Clear the Status log after all errors have been addressed and the Operational Check passes. See

“Status Log Messages” on page 59 for more information.

WARNING Be sure that the HeartStart MRx is not connected to a patient when performing an Operational Check.

To run the Operational Check:

1 Insert a battery charged to at least 20%.

2 Attach a Pads or Paddles therapy cable.

3 Attach an ECG cable.

If possible, talk directly with the user who reported the problem. Identify what they were doing when the problem occurred, and exactly what happened. What was on the display? Were any sounds noticed? Were there operational problems?

If possible, obtain the cables, paddles, battery, etc., that were in use when the problem occurred and use them in your evaluation.

If no further troubleshooting is needed, proceed to Step 14 to repair the device. Otherwise, continue with Step 11.

11. Try to reproduce the problem.

Try to reproduce the problem using the Troubleshooting tables to identify the symptoms and possible solutions and perform any repairs indicated, as in Step 14.

If the problem cannot be reproduced, an intermittent condition or operator error is likely. Check the device’s repair history (Step 12.)

12. Examine the device’s repair history.

Some intermittent problems cannot be reproduced. If the device was returned before for the same problem, replace the most likely subassembly.

13. Run the Service tests, if needed.

Use the tests available in Service Mode to focus in on possible causes. See“Service Mode Tests” on

page 205 for more information.

14. Repair any problems found.

Follow the procedures in the Repair chapter to replace defective parts or subassemblies. When the repair is complete, continue with Step 15.

15. Verify the device’s performance.

Use the procedures found in the Performance Verification chapter to verify that the device is operating properly. Be sure the testing you perform is appropriate for the level of repair. The requirements for testing are described in “Required Testing Levels” on page 196.

4Repair Who Should Perform Repairs

Who Should Perform Repairs

Only qualified technical personnel who have been trained in the safe and proper servicing of the HeartStart MRx should open the monitor/defibrillator case, remove and replace components, or make adjustments. If your medical facility does not have qualified technical personnel, contact the Response Center or your local Philips representative.

WARNING HeartStart MRx service should only be performed by qualified service personnel, in accordance with

this document, the HeartStart MRx Service Manual.

Repair Philosophy

The repair philosophy of the HeartStart MRx is subassembly replacement.

Examples of subassemblies are the printer, the Processor PCA, and selected connectors and other items. Repairs that involve replacing individual components on a PCA are not supported.

CAUTION Individual component replacement should not be attempted. Component level repair is inadvisable

due to the extensive use of surface mount technology and the high parts-density on the circuit boards. Unauthorized component replacement can impair performance of the HeartStart MRx.

4Repair Repair Notes

Repair Notes

The following sections give details of how to successfully work with the internal assemblies of the HeartStart MRx.

TIP If your HeartStart MRx still has a 64 MB data card, then it is recommended to perform the M4773A

(internal and external 256 MB Data Card) upgrade next time you perform an internal repair.

Safety Precautions

WARNING Remove all power sources (AC, battery, DC) before opening the HeartStart MRx. Failure to do so may

allow the device to charge without warning and could result in serious injury or death.

CAUTION Take the necessary precautions against shock or injury before you conduct monitor/defibrillator tests

or repairs.

• Only properly trained technicians should service the device.

• The device can contain deadly voltages even if the device is turned off.

• Make sure the device is disarmed. (To disarm the defibrillator, press [Disarm]. If the Shock button has not been pressed within the time period specified in the Time to Auto Disarm Configuration setting, the defibrillator disarms automatically. Additionally, when the HeartStart MRx is fully charged, you can disarm it any time by turning the Therapy Knob to the “Off” position.)

• Make sure that you disconnect all power before opening the device.

• Make sure you discharge the device before working with it.

• Make sure you work in a static-safe environment. Use a static control wrist band, in conjunction with an antistatic pad which is grounded per the manufacturer’s instructions.

• Special cleaning technologies are used during the manufacturing of the PCAs. Be careful not to touch the surface areas of the PCAs with bare hands. Additionally, oil from hands can affect product performance.

Flex Circuit Connections

In order for flex circuit connections to function properly, they must be disconnected and reconnected as follows:

• Always unlatch the PCA-mounted connector before removing the flex circuit, and hold the latch open while reinserting the flex circuit into the connector.

• When reconnecting, align the flex circuit carefully in its receptacle. Make sure it is both centered from side to side in the connector and oriented at 90 degrees to the connector.

• Be sure the flex circuit is fully seated in the connector and the connector is properly latched.

Repair Notes 4Repair

Flex Circuit Handling

The flex circuits are delicate and can be damaged by improper handling:

• Do not bend sharply.

• Do not scrape the contact surface against other parts.

• Handle the flex with bent-tip needle-nose pliers whose jaws are covered with a soft material (such as plastic tubing or tape).

Internal Connections

Whenever troubleshooting indicates a particular PCA may be at fault, it is always good practice to check all the connections to that PCA and retest before replacing the PCA.

Cable and Assembly Placement

How the wires and cables are routed and dressed inside the chassis plays an important role in two areas: in preventing long term wear problems, and in reducing electromagnetic and radio frequency interference emitted by the monitor/defibrillator.

• When you disassemble any part of the device, pay special attention to how cables and wires are routed.

• When you reassemble the device, be sure to route and dress all cables and wires as they were originally.

• Return all components to their original position within the case.

Device Reassembly

If you do not reassemble the device correctly, it may no longer be properly sealed. This could result in water damage to the device. Be sure to maintain the water-resistant seal by:

• Placing all gaskets in their proper locations.

• Correctly assembling all parts that mate with gaskets (making sure the gaskets are not wrinkled or pinched).

•Replacing all screws.

• Making sure that screws are not cross-threaded and that they are firmly tightened.

• Tightening M3 screws to 6-inch pounds and M4 screws to 10-inch pounds.

Disposal

Prior to disposal, remove the batteries. Then dispose of the device in accordance with your country’s regulations for equipment containing electronic parts.

WARNING To avoid contaminating or infecting personnel, the environment, or other equipment, make sure you

disinfect and decontaminate the monitor/defibrillator appropriately prior to disposal.

Properly dispose of or recycle depleted batteries according to local regulations. Do not puncture, disassemble, or incinerate batteries. Be careful not to short the battery terminals because this could result in a fire hazard.Disposal of the device with the battery inserted presents a potential shock hazard.

4Repair Repair Tools and Equipment

Disposing of Empty Calibration Gas Cylinders

To dispose of empty calibration gas cylinders:

1 Empty the cylinder completely by pushing the pin of the regulator valve or by pulling out the pin

of the fill wave using a tire valve stem wrench or a pair of needle-nose pliers.

2 When the cylinder is empty, either remove the valve stem from the fill (or regulator) hole, or drill a
