About the Device
Energy Delivery
Device Description
3-2
The LIFEPAK 20/20e defibrillator/monitor (device) is a complete, acute, cardiaccare 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.
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 hard paddles or internal paddles).

Power Mux — The power mux switches battery power in and out of VBatt, depending on power availability and load draw within the device. This circuit is under supervisory control of the CPU and provides the current voltage from the A07 Battery and A09 AC Power Supply Module to the CPU. The circuit automatically switches from ac power to battery power if the voltage from the ac power supply falls rapidly. Low voltage is detected by the
A09 AC Power Supply Module and broadcast to the other PCBs through the device internal communication buses.
Battery Charger (LIFEPAK 20 defibrillator/monitor) — The battery charger is a constant current charger designed specifically to support the A07 NiMH
Battery selected for the device. NiMH batteries are not designed for trickle charging, so the A09 AC Power Supply Module keeps track of the amount of time the device has been operating from battery power. Charging is performed following high-use incidents and periodically when the batteries are not in high use. Charging can occur while the unit is powered on or while the unit is powered off, depending on need. The battery charger is designed to charge the internal battery, usually in less than two hours.

Power Switch — A power switch is a control circuit that detects the
ON button selection from the A05 User Interface PCB or a timer event from the
A01 System Control PCB to power up the device. This portion of the
A04 Therapy PCB is powered at all times, with very low quiescent current draw. When a power-on request is detected, this circuit switches VBatt
(battery and/or ac converted dc power) provided by the A03 Power Module to the remaining PCBs in the device. Low Battery (Battery Fail) is detected and a discrete signal is broadcast to other PCBs if battery voltage falls rapidly or reaches the point where normal operation is no longer feasible.
Cap Charger — The cap charger is a high-voltage, patient-isolated circuit that charges the A13 Energy Capacitor to the correct voltage for biphasic defibrillation (2 to 360 joules). Control is provided by the CPU, and capacitor voltage is provided back to the CPU for feedback. The cap charger is designed to nominally provide maximum charge rates and to automatically scale back to slower charge rates when low battery voltage is detected.
Pacer Power Supply — The pacer power supply is a patient-isolated circuit that charges the A13 Energy Capacitor up to the correct voltage for pacing.
Control is provided by the CPU, and voltage regulation is maintained locally within the pacer supply. Capacitor voltage is provided back to the CPU for control through the cap charger circuitry.

H-Bridge — The H-Bridge is a patient-isolated circuit that creates the biphasic defibrillation waveform. A combination of silicon controlled rectifiers
(SCR) and insulated gate bipolar transistors (IGBT) are used to place a positive-oriented defibrillation pulse across the patient load, followed immediately by a negative-oriented defibrillation pulse. The defibrillation pulse is delivered through the relay and W01 Therapy Connector assembly to the external therapy cable on the outside of the device.
Pacer — The pacer is a patient-isolated circuit that creates the pacing waveform. A portion of the H-Bridge circuitry is used to support the pacer by providing energy from the A13 Defibrillation Capacitor. A current drive is used to control the amount of current provided to the patient during pacing.
Relay — The relay provides patient isolation from the pacing and defibrillation circuitry when not in use. The relay is closed when the pacing current is set above zero and stays closed until the pacing current is set back to zero.

When an internal program or process fails to execute properly, an error code is logged and the service indicator LED turns on. Errors 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 error code(s).
Error codes stored in the

error. Error codes can indicate transient electromagnetic interference (EMI) or
. If you suspect transient EMI or ESD as the
source of an error, clear the error code(s), and cycle the power. If the error code does not reoccur, it may have been the result of EMI or ESD.
Note: Alway reload device software to the current version anytime a circuit board is replaced.
To process an error code:
1. Note any problems with the device and consult the
2. Review error codes in the

The service indicator LED does not indicate the presence of errors in the Service
Log. The service indicator LED illuminates when an error code is written to the
Service Log. Refer to
to resolve the problem.
For example, if the service indicator illuminates when you turn on the device, an error 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 error codes in the Service Log. You must review the Service Log and resolve the error code that was written there in the first instance.

Device User Test
Troubleshooting

When you turn on the device, a series of self-tests occur. If errors are detected, the service indicator LED illuminates. 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
).

Device Useful Life
Preventive Maintenance
8-7
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).

Static-Sensitive Devices (SSD)
About SSD Handling
The SSD Symbol
Replacement Procedures
10-8
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:
SSDs are identified with the following warning symbol:
ATTENTION
Always perform repair or maintenance on a static-dissipative mat that is connected to earth ground.
