LIFEPAK 20e Defibrillator/Monitor Device Description
Introduction
About the Device The LIFEPAK 20e defibrillator/monitor (device) is a complete, acute, cardiac-care response system with both manual and semiautomatic defibrillation operation. When clinically indicated, the device enables the operator to deliver a brief, high-energy pulse of electricity to the patient’s heart. Operators can preconfigure the device to reduce complexity during normal operation.
Energy Delivery The device generates a biphasic truncated exponential (BTE) shock pulse for defibrillation. The standard method of energy delivery is through self-adhesive QUIK-COMBO® pacing/defibrillation/ECG electrodes. When using these disposable defibrillation electrodes (DDEs), internal circuitry continuously measures the impedance between the electrodes and allows defibrillation only when the defibrillation electrodes are attached to the patient. The user can select from a variety of optional accessories for energy delivery (for example, standard paddles or internal paddles).

LIFEPAK 20e Defibrillator/Monitor Device Description
Introduction (continued)
Manual Mode Operation
In manual mode (AED MODE indicator off), the device enables the operator to manually select an energy level, initiate a charge sequence, and apply energy in either direct or synchronized modes. When the operator selects the VF/VT ALARM from the ALARMS menu, the continuous patient surveillance system (CPSS) monitors the patient’s ECG for a shockable rhythm. A suspect rhythm alerts the operator with a priority tone and screen message. The operator can then follow locally established guidelines for the administration of defibrillation therapy.
AED Mode Operation In AED mode (AED MODE indicator on), the device uses the CPSS to monitor the patient’s ECG for a shockable rhythm. A suspect rhythm alerts the operator with a priority tone and screen message. The operator may continue by pressing the ANALYZE button, which allows the Shock Advisory System to analyze the ECG rhythm and make recommendations. The operator can then follow locally established guidelines for the administration of defibrillation therapy. For more information about CPSS and Shock Advisory System, refer to Appendix E in the operating instructions.

Processing Service Codes
Introduction When an internal program or process fails to execute properly, a service code is logged and the service indicator LED turns ON. Service codes rarely occur and should be investigated thoroughly by qualified service personnel before the device is placed back into active use. Always complete the performance inspection procedure (PIP) after encountering and clearing any service code(s).Service codes stored in the Service Log may not necessarily indicate a permanent error. Service codes can indicate transient electromagnetic interference (EMI) or electrostatic discharge (ESD). If you suspect transient EMI or ESD as the source of an error, clear the service code(s), and cycle the power. If the service code does not reoccur, it may have been the result of EMI or ESD.
Processing Service Codes
To process service code(s):1. Note any problems with the device and consult the Troubleshooting Chart.2. Review service codes in the Service Log. Record the service code(s),
including the date, time, and service code extension.3. Select CLEAR LOG in the service log, and then turn the device OFF.

4. Complete the performance inspection procedure (PIP). – If completed successfully, the device may be returned to regular use.
(The service code(s) may have been related to EMI or ESD.) – If the service LED turns ON at any time during the PIP, stop the PIP and
continue to the next step in this procedure.5. Consult the Troubleshooting Chart for the suggested corrective action for
your PIP failure. -OR-Review the Service Log codes, and then locate the service code in the Service Code Table.Note: Use the links in the Service Code Categories table to quickly jump to the correct code in the Service Code Table.
6. Read the corrective action(s). If the corrective action calls for the replacement of a part, click the link in the Troubleshooting Chart or click the appropriate part in the footer at the bottom of the Service Code Table pages to jump to the corrective action process.
7. Service the device based on these inputs, and then repeat the PIP.8. For persistent error codes, contact your local Physio-Control service or sales
representative.

Service Indicator
The service indicator LED does not indicate the presence of errors in the Service Log. The service indicator LED illuminates when a service code is written to the Service Log. Refer to Processing Service Codes to resolve the problem.For example, if the service indicator illuminates when you turn on the device, a service code has been written to the Service Log. If you cycle the power, and the service indicator does not illuminate again, it does not mean that there are no codes in the Service Log. You must review the Service Log and resolve the service code that was written there in the first instance.

Device User Test
When you turn on the device, a series of self-tests occur. If errors are detected, the service indicator LED illuminates and a printed report indicates that the test failed. Self-testing does not occur only at power-on; it is continuous while the device is turned on.Pressing the OPTIONS button and selecting USER TEST does not initiate a self-test cycle; rather, it monitors self-test status and produces reports. The device waits until the next self-test cycle is complete and then reports USER TEST PASSES. One operation is specific to the OPTIONS/USER TEST feature. This operation consists of one cycle of charging the defibrillator capacitor to 10 joules and then dumping the charge. If this operation does not pass, the service indicator LED illuminates and an error is written to the Service Log (refer to Processing Service Codes).

Device Useful Life
During product development, the device and subassemblies are subjected to rigorous life testing. This testing and the routine testing and maintenance program recommended in this service manual will help provide reliable device operation for many years.However, both rapid technological changes and the availability of replacement parts limit the useful life of all modern medical devices. The American Hospital Association suggests a five-year useful life expectancy for defibrillators (Estimated Useful Lives of Depreciable Hospital Assets, Revised 1998 Edition). Similarly, the U.S. Army lists an eight-year life expectancy for defibrillators (technical bulletin: Maintenance Expenditure Limits for Medical Materiel, TB MED 7 Revision 8 October 1993).
Support Policy Physio-Control provides full technical support and replacement parts for a period of eight years from the date of shipment from our manufacturing facility. After this eight-year period, Physio-Control provides technical support and replacement parts on an as-available basis.

Static-Sensitive Devices (SSD)
About SSD Handling Many electronic semiconductor devices (such as MOS ICs, FETs, optical isolators, or film resistors) can be damaged by the discharge of static electricity. Static-charge buildup is very common. Static discharges commonly occur when the operator wears synthetic clothes and transfers the charge to any object touched. These discharges can damage or destroy static-sensitive devices (SSDs). In most cases, the discharge is not even perceptible to the person who causes it.To prevent static-discharge damage to SSDs, observe the following precautions during any open-case test, maintenance, or repair procedures:
The SSD Symbol SSDs are identified with the following warning symbol:
Always perform repair or maintenance on a static-dissipative mat that is connected to earth ground.

Static-Sensitive Devices (SSD) Handling
Many electronic semiconductor devices (such as MOS ICs, FETs, optical isolators, or film resistors) can be damaged by the discharge of static electricity. Static-charge buildup is very common. Static discharges commonly occur when the operator wears synthetic clothes and transfers the charge to any object touched. These discharges can damage or destroy static-sensitive devices (SSDs). In most cases, the discharge is not even perceptible to the person who causes it.To prevent static-discharge damage to SSDs, observe the following precautions during any open-case test, maintenance, or repair procedures:
The SSD Symbol SSDs are identified with the following warning symbol:
Always perform repair or maintenance on a static-dissipative mat that is connected to earth ground.
