GENERAL
DESCRIPTION
Long an innovator in
emergency and trauma
medicine, Life Support
Products has been a
primary manufacturer of
oxygen delivery devices for
field use in the United
States and worldwide since
1979. LSP is also a
manufacturer of a wide
range of trauma, burn and
rescue devices.
Specifications for the
LSP AutoVent 2000/3000,
including the Patient Valve
Assembly, Control Module,
and Regulators intended
for use with this device, are
included in the Appendix
of this manual.
The Life Support Products
AutoVent 2000/3000
represent a major
breakthrough in pneumatic
technology. They are
intended for the ventilatory
assistance of patients
following cardiac arrest,
near drowning, trauma,
paramedical transport, and
other circumstances
requiring ventilatory
assistance.
The LSP Automatic
Ventilator (AutoVent
2000/3000) time-cycled,
constantflow, gas-powered
ventilators offer controlled
ventilation at rates from 8
to 20 breaths per minute
(BPM) in the AutoVent
2000 version, and 8 to 27
breaths per minute in the
AutoVent 3000 version.
The attached Patient Valve
Assembly allows a patient
to draw supplemental gas
flow (up to 48 LPM) with
spontaneous effort.
Designed for transport and
emergency medical use,
the AutoVent 2000 delivers
from 400 ml to 1200 ml
volume. The AutoVent
3000 delivers from 200 to
1200 ml in volume.
Both AutoVents deliver
peak pressures up to
60+5 em H20 at flow
flow rates from 16 to 48
liters per minute (LPM).
They are small, compact
units ideally suited for
emergency and transport
situations at temperature
extremes from O°F to
125°F. Operating
power is obtained from
standard 50 psi source
gas. They are simple to
assemble and operate,
and their functions are
easily understood. The
Ventilators meet or
exceed the American
Heart Association (AHA)
guidelines for
resuscitation.
An Audible alarm
sounds whenever
ventilatory pressures
approach the preset
pressure limit, alerting
the operator. This alarm
will continue to sound
until the airway pressure
drops or the system
cycles to the expiratory
phase.
WARNING: Use only
as directed. Improper
usage or unauthorized
modification of this
product may result in
user or patient injury.

Pressure Limit Alarm
Module
An audible pressure limit alarm is located in the Patient
Valve Assembly. This alarm sounds whenever the patient
airway pressure approaches the designed pressure limit.
The Pressure Limit Alarm will continue to sound during the
inspiratory phase until either the airway pressure decreases
or the ventilator cycles off to begin the expiratory phase.
In addition to functioning as a high pressure alarm the
alarm module also provides additional air entrainment
during the Intermittent Mandatory Ventilation (IMV) mode
should the patient's inspiratory flow rate exceed the flow
delivery from the control module. The entrainment of
ambient air occurs through the blue rubber diaphragm
located on the side of the alarm module.
WARNING: If the maximum pressure limit is
reached, the pre-set tidal volume may not be
delivered to the patient. Inspiratory time will
remain constant, however, and an inspiratory
hold will be maintained with no additional
volume being delivered until the ventilator cycles
to the expiratory phase. This warning also
appears under Tidal Volume in the Performance
Characteristics.
WARNING: Should the blue rubber diaphragm
blow outward from the alarm module's air
entrainment ports, remove the AutoVent
immediately from service, and contact your LSP
distributor.
Source Gas Inlets
inlets connect the Patient Valve with the Control Module.
The top inlet: (1) Supplies the actuator assembly and is a
nippled connector. The bottom inlet: (2) Supplies source
gas to the patient at a constant flow and is a diameter
index safety system (DISS) oxygen connector.

the inside of the Patient Valve Assembly. The exhalation /
valve allows the patient to exhale through the Patient Valve
Assembly once the inspiratory cycle is completed, whether
ventilator-controlled, or on demand. This valve can be
accessed by removing the outlet adapter on the Patient
Valve Assembly.
The Control Modules for
the AutoVent 2000/3000
are designed to be
compact, durable and easy
to use. The units are
constructed to perform in
the difficult environments of
paramedic or transport
operations. Their features
include an impactresistant
case with shock absorbing
bumpers and easy to read
controls for independently
setting Breaths Per Minute
(BPM), Tidal Volume and
Inspiratory Time (AutoVent
3000 only). The reverse
side of the case also has
simplified operating
instructions for ease of

located on the left side of the Control Module and
marked with an arrow, the source gas inlet is a standard
diameter index safety system (DISS) male oxygen connector.
When a high pressure line is attached to a 50 psi source
gas from a cylinder or bulk oxygen source, this gas is
delivered to the Control Module and cycled for delivery to
the Patient Valve Assembly.
An Air/Oxygen Blender can also be inserted in line with
this system, between the source and the ventilator, to deliver
a specified oxygen concentration.
**NOTE: Use of an Oxygen Analyzer is recommended
prior to patient use in order to accurately measure the
desired oxygen concentration to be delivered. **
located on the right side of the Control Module body
and marked with arrows, the patient valve outlets connect
the Control Module with the Patient Valve Assembly. The
top outlet (1) Supplies source gas to the Patient Valve
Assembly at a constant flow and is a diameter index safety
system (DISS) oxygen connector. The bottom outlet: (2)
Supplies the Patient Valve Actuator and is a unique 7/16
inch threaded female connecior.
This control sets the ventilator rate from 8 to 20 BPM in the
AutoVent 2000 version, and from 8 to 27 BPM in the
AutoVent 3000 version. Adjusting the knob clockwise
decreases the breathing rate and adjusting counter clockwise
increases the rate. Source gas is available on demand, even
in the "O" position up to 48 LPM depending on Tidal Volume
setting, from the Patient Valve Assembly to allow the patient to
breathe spontaneously.

This control adjusts the volume available to the patient
during a breath and is adjustable from 400 ml to 1200 ml in
the AutoVent 2000 version, and from 200 to 1200 ml in the
AutoVent 3000 version. Turning the knob clockwise increases
tidal volume. Turning the knob counter clockwise decreases
tidal volume. Following a volume adjustment change, the tidal
volume stabilizes after one breath and remains constant.
WARNING: If the maximum pressure limit is reached,
the pre-set tidal volume may not be delivered to the
patient. Inspiratory time will remain constant,
however, and an inspiratory hold will be maintained
with no additional volume being delivered until the
ventilator cycles to the expiratory phase. This
warning also appears under Pressure Limit Alarm

(Continued) Valve Assembly
Remove the outlet adapter and exhalation valve assembly
from the Patient Valve Assembly, Leave tubing assembly
connected.
Clean all foreign matter from the components with a mild
soap solution, being careful not to get any liquid inside the
Patient Valve Assembly. Rinse the parts thoroughly in clean
water.
Immerse the outlet adapter and the exhalation valve
assembly from the Patient Valve in a disinfectant or
bacteriocidal solution for a minimum of 10 minutes.
Remove the outlet adapter and the exhalation valve
assembly from the solution and rinse thoroughly with water.
Rinse repeatedly to assure that all the solution is removed.
Place the Patient Valve, outlet side down, into a shallow
container with not more than 1/2 inch of disinfectant or
bacteriocidal solution. The Patient Valve should remain in
this solution for a minimum of 10 minutes. Leave tubing
assembly connected.
Remove the Patient Valve from the solution and rinse
thoroughly with water. Dry assembly using approved
standard methods such as hot air drying.

3. Cleaning the Non-
Rebreathing Valve
CAUTION: If the flapper valve is twisted or the
locating bosses are not properly positioned, the
Patient Valve Assembly will not function
properly. Always make sure the valve is flat
and properly seated.
Immediately after cleaning, reassemble the Patient Valve
Assembly and connect to the Control Module. Turn on the
oxygen supply and allow the ventilator to cycle several
times to blow out any liquid which may have gotten inside
during the cleaning process.
Test the unit for proper function prior to each patient use.
Attach an inflatable test lung, P/N L109, to the Patient
Valve Assembly outlet and complete the test at different
rates and tidal volumes.
Clean after each use. All components of the P/N L496
NonRebreathing Valve are autoclavable. To disassemble,
unscrew the valve inlet from the outlet and remove the
duckbill diaphragm. The individual components can now
be cleaned. If autoclaving systems are not available, you
may also sterilize via cidex or other bacteriocidal solution.
Be sure to rinse and dry all parts thoroughly before re-
assembling. After cleaning, inspect all parts for damage or
breakage. Replace any damaged or broken parts.
Store the unit in a clean, dry area within a temperature
range of -40'F to 160°F.
After long periods of storage, the unit should be fully
tested before use in accordance with the checkout
procedures in this manual.

Warnings
If the maximum pressure limit is reached, the pre-set tidal
volume may not be delivered to the patient. Inspiratory
time will remain constant, however, and an inspiratory hold
will be maintained with no additional volume being
delivered until the Ventilator cycles to the expiratory phase.
This warning also appears under Tidal Volume in
the Performance Characteristics.
Should the blue rubber diaphragm blow outward from
the alarm module's air entrainment ports, remove the
AutoVent immediately from service. And contact your LSP
Distributor.
