LIFEPAK 12 defibrillator/monitor series Preface

Device Tracking

USA only, including US government-owned devices:
The Food and Drug Administration requires defibrillator manufacturers and

distributors to track the location of defibrillators. If your defibrillator has been
sold, donated, lost, stolen, exported, or destroyed, or if it was not obtained
directly from Medtronic Physio-Control, please notify Medtronic Physio-Control
at 1.800.442.1142, extension 4530.

General information related to device tracking:
It is important to maintain accurate records of defibrillator location within your

facility or system. Maintenance of such records eases the process of locating
defibrillators should it be necessary to modify them. Defibrillators should be
tracked by both the manufacturer’s part and serial number. Internal asset or
tracking numbers may also be useful in maintaining adequate control of
defibrillators.

About the Device

Energy Waveforms

Energy Delivery

The LIFEPAK 12 defibrillator/monitor is a complete acute cardiac care response
system with both manual and semi-automatic defibrillation operation. When
clinically indicated, the LIFEPAK 12 defibrillator/monitor allows the operator to
deliver a brief, high-energy pulse of electricity to the heart of the patient.
Operators may pre-configure the device to reduce complexity during normal
operation. Built-in service features include self-calibration and testing.

The LIFEPAK 12 defibrillator/monitor series includes two distinct versions
characterized by different defibrillator waveform technologies: monophasic and
biphasic. The Monophasic (Edmark) device generates a monophasic damped
sinusoidal (MDS) shock pulse, while the Biphasic device generates a biphasic
truncated exponential (BTE) shock pulse for defibrillation.

The LIFEPAK 12 defibrillator/monitor 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 may select from a variety of optional accessories for energy delivery
(for example, standard hard paddles or internal paddles).

LIFEPAK 12 defibrillator/monitor series Device Description

Functional Description Page 3 of 21

A01 System PCB

The A01 System PCB integrates and controls all functions of the LIFEPAK 12
defibrillator/monitor. There are two primary components: A 32-bit Reduced

Instruction Set Computer (RISC processor), which functions as the central

processing unit (CPU) for intensive number processing tasks, and an

Application-Specific Integrated Circuit (ASIC), which operates as the

interface between the CPU and all other device therapeutic, monitoring, data
management, and display sub-systems.

The following discussion identifies major sub-systems of the A01 System PCB
and their basic functions.

■

Power Supplies — The A01 System PCB uses SW_VB (Switched Battery

Voltage) from the A03 Power PCB (via the A04 Therapy PCB) to originate
four power supplies for use throughout the device as follows:

– +5 V logic power for use on the A01 System PCB within the PCMCIA,

DUART, RTC, ASIC, and Audio sub-systems and the A04 Therapy PCB.

– +3.3 V logic power for use on the A01 System PCB within the RISC

CPU, DSP, Main Memory, and ASIC sub-systems.

– ±12 V analog power for use on the A01 System PCB, A04 Therapy PCB,

and for A11 LCD Assembly contrast.

64

Previous Page Table of Contents Section Contents

– +24 V power for use in the A01 System PCB Printer sub-system.

■

A01 System PCB

ECG Front End — The LIFEPAK 12 defibrillator/monitor simultaneously

(continued)

captures inputs from up to 10 independent patient connected leads for use in
the interpretive 12-lead algorithm and basic ECG waveform display. The
ECG Front End performs the functions of patient isolation, electrostatic
discharge and defibrillation protection, lead selection, baseline DC restore,
bandwidth filtering, internal pacemaker detection, and ECG sampling via
analog-to-digital conversion (ADC). Results from the ADC process pass
across the isolation barrier to the A01 System PCB Digital Signal Processor
(DSP) for filtering and signal conditioning before use by the RISC CPU. ECG
input is through the parameter bezel W07 ECG Connector Cable.

■

IP Front End — The Invasive Pressure (IP) circuitry processes the input

signal from a disposable IP transducer through the IP input connectors on
the LIFEPAK 12 defibrillator/monitor parameter bezel. Two input connectors
are provided for simultaneous monitoring of two IP channels. The W33
Invasive Pressure Harness provides the connection from the parameter
bezel to the A01 System PCB assembly, where the IP preamplifier circuitry
is located.
The IP preamplifier is isolated from the AC power ground by the ECG
preamplifier iso-barrier. The transducer drive circuitry supplies a positive

2.5 V and a negative 2.5 V excitation voltage to the resistive bridge-type

transducer. The output signal from the transducer is conditioned by a

Back

Index Next Page

LIFEPAK 12 defibrillator/monitor series Device Description

Functional Description Page 5 of 21

A01 System PCB
(continued)

low-pass filter at the input of an instrumentation amplifier, which amplifies
the signal approximately 400 times. The signal is then multiplexed to the A-D
converter, digitized, and then sent serially across the iso-barrier for DSP
processing and display.

■

Printer Controller — The LIFEPAK 12 defibrillator/monitor uses either a

50 millimeter (mm) or 100 mm thermal array printer. In either case, the A01
System PCB Printer Controller governs motor speed, adjusts print strobe
pulse width, senses paper presence and door closure, senses printhead
temperature, and provides the data to be printed. Printer fonts are stored in
memory devices located on the A01 System PCB.

■

PCMCIA Slot Controller — The LIFEPAK 12 defibrillator/monitor uses a PC

Card (PCMCIA) modem for data transmission to external data management
programs. All internal data exchange between the PC Card and the device is
handled by the A01 System PCB PCMCIA Controller.

maintains the date and time (year 2000 compatible), and provides storage
for instrument user setups, device manufacturing configuration (a Medtronic
Physio-Control proprietary file), and calibration data. The RTC/NVRAM is
powered by a lithium coin cell battery.

■

System Connector Interface — The LIFEPAK 12 defibrillator/monitor may

be connected to external devices for the purposes of analog ECG signal
output, data transmission, factory test, Medtronic Physio-Control field
service data collection, and device configuration during field upgrade.
Except for analog ECG signals, all data communications at the system
connector are at RS-232 levels.

The analog ECG signal output path consists of A01 System PCB
components including a digital-to-analog converter (DAC), low-pass filter,
and electrostatic discharge protection.

The digital communications output path consists of two components: a dual
universal asynchronous receiver/transmitter (DUART); and a level-shifter for

— The RTC/NVRAM

the purposes of converting device internal logic levels to RS-232 levels.

A03 Power PCB

The A03 Power PCB manages application of power to the LIFEPAK 12
defibrillator/monitor from available sources (either of the two batteries or an
attached power adapter). Additional functions include power on/off control,
“smart” battery communication, routing of battery charge currents, battery
voltage measurement, over-current protection fusing, and serial communication
of power status to the A01 System PCB.

A03 Power PCB operation centers around a power processor, which detects the
presence of available power sources, selects a power source for use by the
device, monitors their status (e.g., low battery, replace battery, removal from the
device, etc.), and applies charging currents from an attached power adapter to
the batteries.

When the LIFEPAK 12 defibrillator/monitor is off, closure of the device
control activates A03 Power PCB circuitry to alert the Power processor, which
chooses the appropriate source to originate SW_VB (Switched Battery Voltage)
power. SW_VB is then routed, in turn, to the A04 Therapy PCB and A01 System
PCB for use, as is, and for further processing into system power supply voltages.

A04 Therapy PCB

The A04 Therapy PCB maintains the patient interface for therapeutic purposes.
In addition to developing defibrillation and noninvasive pacing energies, the A04
Therapy PCB ensures safe delivery of those energies, captures
and monitors attachment of the QUIK-COMBO electrodes.

The following discussion identifies major sub-systems of the A04 Therapy PCB
and their basic functions.

■

Defibrillator Processor — The Defibrillator Processor manages operation

of the defibrillator energy storage and delivery functions using serial inputs
from the A01 System PCB ASIC, hardware inputs from external paddles,
and inputs from other A04 Therapy PCB circuitry. Status of the defibrillator
sub-system is reported serially to the A01 System PCB ASIC.

■

Energy Storage Capacitor Charger (ESCC)

Defibrillator Processor, the ESCC converts COM_VB (Common Battery
Voltage) to high-voltage for application to the Energy Storage Capacitor.
Circuitry within the ESCC performs comparisons between stored energy and
target energy to limit charging to the value selected by the user. Additional

— Under control of the

PADDLES ECG

,

circuits compensate the ESCC for low battery voltage, provide over-voltage
protection, and send divided capacitor high voltages to separate safety
monitoring and energy display circuits.

the A04 Therapy PCB integrates control signals from the
external paddles discharge controls), Defibrillator Processor, ESCC, and the
A01 System PCB ASIC. The transfer relay will only be activated to deliver
energy to the defibrillation electrodes when all conditions are satisfied in
each system component.

■

Dump Relay Control — A fail-safe system used to safely dissipate

defibrillation energies from the Energy Storage Capacitor under a number of
circumstances, e.g., change of energy selection, when power is removed,
pacing is activated, QUIK-COMBO leads off, etc. With the exception of
power removal, the Dump Relay Control system functions under the control
of the System and/or Defibrillator processors.

■

QUIK-COMBO Leads Off (Impedance Sense/Motion Detection) — The

LIFEPAK 12 defibrillator/monitor activates leads off/motion detection when
using QUIK-COMBO electrodes. For the purposes of this discussion,
consider the leads off/motion detector and patient system as a simple
voltage divider.

perturbations sensed in the low-amplitude signal developed across the
patient represent motion; gross changes in the sensed signal indicate
electrode disconnection.

QUIK-COMBO ECG Preamplifier performs the functions of patient isolation,
electrostatic discharge and defibrillation protection, baseline DC restore,

facets of noninvasive pacemaker operation and paddles ECG signal
acquisition. Inputs received serially from the A01 System PCB ASIC are
translated into controls to enable Noninvasive Pacemaker delivery of
properly timed pacing impulses at the desired current. Analog ECG from the
Paddles/QUIK-COMBO ECG Preamplifier is processed for local use and for
transfer across the isolation barrier to the A01 System PCB DSP and onto
the A01 System PCB ASIC.

■

Noninvasive Pacemaker — The A04 Therapy PCB Noninvasive

Pacemaker sub-system develops isolated, adjustable current, 20 millisecond
(nominal), trapezoidal transchest pacing impulses. Major components of the
Noninvasive Pacemaker include the Paddles/Pacer Processor, isolated low­and high-voltage power supplies, safety monitors, output current, pulse
width, and pulse shape controls. Controls for, and status of, the Noninvasive
Pacemaker pass serially between the Paddles/Pacer Processor and the A01

The A05 Interface PCB is primarily a signal collector/distributor used to simplify
the routing of cables between the front and rear halves of the LIFEPAK 12
defibrillator/monitor. The majority of signals from the device rear half are
consolidated into the W04 System PCB/Interface PCB Cable and passed to the
A05 Interface PCB for further distribution to front half components, e.g., A09
Small Keypad, A10 Large Keypad, A11 Display Assembly, and A12 Printer
Assembly. The following active circuits reside upon the A05 Interface PCB:

■

Audio Amplifier — Combined Audio Output signals receive final

amplification in the A05 Interface PCB Audio Amplifier prior to application to
the W17 Speaker Assembly.

Saving the Setup
Configuration

The operating defaults for the device are configured while you are in Setup
Mode. Options include general characteristics, Manual Mode and AED Mode
operating characteristics, alarms setup, transmission sites, time-of-day clock,
and many other items. After the setup is complete, turn off the device, which
saves the configuration. The next time the device is turned on, the operating
defaults you selected are active.

The information that follows, with references to the Operating Instructions, shows
you the options available in the Setup Mode. There is also a Factory Reset
option that resets the device to the factory default settings, except for
transmission sites, output ports, initialization strings, and the maintenance
interval, which remain unchanged.

If the owner of the device has a setup configuration that cannot be disturbed, you
have two choices to preserve this setup. The first method is to print the setup

configuration. When service is complete, you can verify the setup and then

manually reset the configuration.

The second method is to send the setup configuration to another LIFEPAK 12
defibrillator/monitor. After service is complete, transfer the configuration back to
the device.

Note:

requires that the software in the device being used for storage of configuration
information is of the same revision. Otherwise potentially unexpected results
may occur once the configuration has been restored to the repaired device.

Procedures

The Performance Inspection Procedures (PIP) are a set of manual test
procedures used for an operational closed-case evaluation of the LIFEPAK 12
defibrillator/monitor. This section describes the test procedures you will perform
to determine if the LIFEPAK 12 defibrillator/monitor is operating within the
required specifications. Investigate and correct any malfunctions or out-of­tolerance conditions detected during the PIP.

The PIP comprises safety and performance tests recommended by AHA/ASHE
(American Hospital Association/American Society for Hospital Engineering)
Maintenance Management for Medical Equipment and International
Electrotechnical Commission (IEC) Technical Report 1288-2, Maintenance of
Cardiac Defibrillators-Monitors.

Perform the PIP as part of a regularly scheduled preventive maintenance
routine. Also, perform the PIP after any repair, replacement, or calibration
procedure. Print the PIP Checklist to record the test results. Also refer to the

Operator Checklist for additional items.
