Safety
Information
Introduction This safety information includes terms and symbols used in this manual or
on the equipment to alert both operating and service personnel of
recommended precautions in care, use and handling of this specialized
medical equipment.
Refer to NFPA (National Fire Protection Association) 99-1990, Health Care
Facilities, and NFPA 70-1990, National Electrical Code, for specific
guidelines on the standards and practices for health-care instruments and
environments.
Terms Certain terms are used in this manual, or on the equipment. Familiarize
yourself with their definitions and significance.
Danger: Immediate hazards which will result in severe personal injury
or death.
Warning: Hazards or unsafe practices which could result in severe
personal injury or death.
Caution: — Hazards or unsafe practices which could result in minor
personal injury or product damage.
Note: Points of particular interest for more efficient or convenient
instrument operation. Additional information or explanation
concerning the subject under discussion.

Following
are
descriptions
of
general
hazards
and
unsafe
practices
that
could
result
in
death,
severe
injury
or
product
damage.
Specific
warnings
and
cautions
not
appearing
in
this
section
are
found
throughout
the
manual.
When charged and discharged, the LIFEPAK 9 defibrillator/monitor
discharges up to 360J of electrical energy through the defibrillator paddles.
Unless discharged properly as described in this manual, this electrical energy
may Cause personal injury or death. Do not attempt to perform this
procedure unless you are thoroughly familiar with the operation of the
LIFEPAK 9 defibrillator/monitor and all accessories.
When discharging the defibrillator into the internal test load, make sure the
standard paddles are securely and properly stored in the paddle storage area
(STERNUM paddle on the left, APEX paddle on the right). This helps prevent
arcing and formation of pits on paddle electrode surfaces. Pitted or damaged
paddle electrode surfaces can cause patient skin burns during defibrillation.
Do not operate this product in oxygen-enriched environments or in the
presence of flammable gases or anesthetics. Explosion or fire can result.
Refer to NFPA (National Fire Protection Association) 99-1990, Health Care
Facilities, and NFPA 70-1990, National Electrical Code, before operating
this product in the proximity of flammable gases or anesthetics.
Do not mount the product directly above the patient. Place the product in a
location where it cannot harm the patient if it should fall from its shelf or
other mounting location.
Do not operate equipment using damaged cables and wires. Broken or
frayed wires, or loose snap fittings may cause interference or loss of signal
and possible equipment failure. Perform frequent electrical and visual
inspections on cables and wires. Pay particular attention to the point at
which the wires enter the terminals. Repeated flexing at these points
eventually causes the wire strands to break.
Do not immerse any portion of the instrument in water or other fluids. Avoid
spilling any fluids on the instrument or accessories.
Do not sterilize this product. Sterilization environments can cause serious
damage. Do not autoclave or gas sterilize accessories unless manufacturer
instructions clearly approve it.

Do not substitute accessories. Use only recommended accessories listed in
Table 5-4 shown on page 5-5. Substitution may cause the instrument to
work improperly.
Make sure that all equipment is interconnected safely in accordance with
NFPA (National Fire Protection Association) 70-1990, National Electrical
Code.
Note:
Within certain governmental jurisdictions, all interconnected
accessory equipment must be labeled by an approved testing
laboratory. It is important that you verify and observe the required
applications in your location. Check leakage current and
grounding requirements after interconnecting this instrument with
accessory equipment.

General Information
Service Before attempting to clean or repair any assembly in this instrument, the
Information technician should be familiar with the information provided in Section 4,
Service and Maintenance.
If the instrument has been dropped, damaged, or abused, a qualified
technician should complete the Performance Inspection Procedure (PIP)
in Section 3, beginning on page 3-1, to confirm whether the instrument is
operating within specifications. If calibration or more extensive testing is
required, a qualified technician can perform the Test and Calibration
Procedure (TCP) in Section 3. Component replacement and internal
adjustments must be performed only by service personnel qualified by
appropriate training and experience.
Use of non—Physio—Control defibrillation electrodes, batteries, accessories,
or adapter devices may void Safety Agency Certifications and warranty.
For assistance in servicing the instrument in the US, call Physio-Control at
1-800-442-1142. In other countries contact the local Physio-Control
representative.

Description 1
The recorder can print the ECG trace, time and date, ECG lead and size,
heart rate, and SYNC (if activated). The recorder automatically prints for
approximately 16 seconds when a heart rate violation occurs. When the
CODE SUMMARY pushbutton is pressed, the recorder prints the stored
CODE SUMMARY critical event record data, including event summary and
recorded ECG trace data.
The ac line power fuses, a ground connector, and an ECG signal output
connector are accessible at the rear panel. The LIFEPAK 9 defibrillator/
monitor specifications are listed in Table 1-1.

LIFEPAK 9 defibrillator/monitor
Functional The overall function of the LIFEPAK 9 defibrillator/monitor is shown in
Descri ption Figure 1-2. The defibrillator/monitor includes six mechanical assemblies
(Keypad, Rear Panel Membrane Switch, Strip Chart Recorder, Transfer
Relay, Paddles, and Battery Pack) and five Printed Circuit Board (PCB)
assemblies (Power Supply, Power Conversion, Interconnect, Main, and
Display).
The Keypad and Rear Panel Membrane Switch Assemblies receive operator
input. The Strip Chart Recorder Assembly provides printed output. The
Transfer Relay and Paddle Assemblies help deliver defibrillator pulses. The
Battery Pack provides temporary backup power.
The Power Supply PCB functions over the full range of input voltages from
90Vac to 270Vac at 50Hz or 60Hz without input line voltage selection. The
Power Supply PCB converts the ac line power to the nominal +18.8Vdc
supplied to the Power Conversion PCB.
The Power Conversion PCB performs a variety of power-handling functions:
power on/off switching, generation of additional power supply voltages,
defibrillation charging, and stored energy transfer. A test load circuit is also
present on the Power Conversion PCB.
The Interconnect PCB provides the electrical connection between the Main
PCB and the Power Conversion PCB. It also contains circuitry to produce
the audible tones and to drive the front panel LEDs.
The Main PCB has three major sections of circuitry: the Preamp, the System
Controller, and the Display/Recorder Interface. The Preamp receives input
from both the 3-lead patient cable and QUIK-LOOK paddles inputs. The
System Controller directs the overall operation of the other circuits. QRS
detection, rate calculation and alarms, and synchronous cardioversion are all
implemented in the System Controller software. The current state of the
System microprocessor and the ECG data are transmitted from the System
microprocessor to the Display/Recorder microprocessor, allowing the
Display/Recorder microprocessor to select and format the appropriate CRT
messages and recorder annotations.
The Display PCB/CRT Assembly contains a Monitor PCB that drives the
5-inch diagonal Cathode Ray Tube (CRT). It uses electromagnetic beam
deflection and incorporates vertical and horizontal deflection circuitry to
produce a raster scan.
