Definitions
This manual uses three special indicators to convey information
of a specific nature. They include:
Warning
Indicates a condition that can endanger the patient or the
ventilator operator.
Caution
Indicates a condition that can damage the equipment.
NOTE:
Indicates points of particular emphasis that make operation of
the ventilator more efficient or convenient.
Warnings, cautions, and notes
Please take the time to familiarize yourself with the following
caveats as they cover safety considerations, special handling
requirements, and regulations that govern the use of the 840
Ventilator System. To ensure proper servicing and avoid the possibility of physical
injury, only qualified personnel should attempt to service or
make authorized modifications to the ventilator.
The user of this product shall have sole responsibility for any
ventilator malfunction due to operation or maintenance
performed by anyone not trained by Puritan Bennett staff. To avoid an electrical shock hazard while servicing the
ventilator, be sure to remove all power to the ventilator by
disconnecting the power source and turning off all ventilator
power switches. To avoid a fire hazard, keep matches, lighted cigarettes, and all
other sources of ignition (e.g., flammable anesthetics and/or
heaters) away from the 840 Ventilator System and oxygen
hoses. iv
840 Operators & Technical Reference Manual
4-075609-00 Rev. E (07/03)
Do not use oxygen hoses that are worn, frayed, or
contaminated by combustible materials such as grease or oils.
Textiles, oils, and other combustibles are easily ignited and
burn with great intensity in air enriched with oxygen.
In case of fire or a burning smell, immediately disconnect the
ventilator from the oxygen supply, facility power, and backup
power source. When handling any part of the 840 Ventilator System, always
follow your hospital infection control guidelines for handling
infectious material.
Puritan Bennett recognizes that cleaning, sterilization,
sanitation, and disinfection practices vary widely among
health care institutions. It is not possible for Puritan Bennett
to specify or require specific practices that will meet all needs,
or to be responsible for the effectiveness of cleaning,
sterilization, and other practices carried out in the patient care
setting.
Puritan Bennett does recommend that users of its products
that require cleaning and sterilization/disinfection consider
the National Standards and Recommended Practices for
Sterilization published by the Association for the Advancement
of Medical Instrumentation (AAMI), as well as the following
Centers for Disease Control (CDC) publications: Guideline for
Maintenance of In-use Respiratory Therapy Equipment and
Guidelines for Prevention of Nosocomial Pneumonia. Patients on life-support equipment should be appropriately
monitored by competent medical personnel and suitable
monitoring devices.
The 840 Ventilator System is not intended to be a
comprehensive monitoring device and does not activate
alarms for all types of dangerous conditions for patients on
life-support equipment. For a thorough understanding of ventilator operations, be sure
to thoroughly read this manual before attempting to use the
system. 4-075609-00 Rev. E (07/03)
840 Operators & Technical Reference Manual
v Before activating any part of the ventilator, be sure to check
the equipment for proper operation and, if appropriate, run
SST as described in Section 3 of the operators guide. Do not use sharp objects to make selections on the graphic
user interface (GUI) display or keyboard. US federal law restricts this device to sale by or on the order of
a physician. Check the ventilator periodically as outlined in the 840
Ventilator System Service Manual; do not use if defective.
Immediately replace parts that are broken, missing, obviously
worn, distorted, or contaminated. An alternative source of ventilation should always be available
when using the 840 Ventilator System. The 840 Ventilator System is a member of the 800 Series
family of products. Any accessory whose model number is 80x
(for example, the 802 Backup Power Source or 804
Compressor) operates with all 800 Series ventilators. An
accessory whose model number is 84x operates only with a
model 840 Ventilator System.
Year of manufacture
The graphic user interface (GUI), breath delivery unit (BDU),
backup power source (BPS), and compressor contain a specific
year of manufacture applicable only for that assembly. The year of
manufacture is indicated by the fifth and sixth digits of the serial
number which is located at the back panel of the GUI, BDU, and
BPS, and the side panel of the compressor.

Electromagnetic susceptibility
The 840 Ventilator System complies with the requirements of IEC
601-1-2 (EMC Collateral Standard), including the E-field
susceptibility requirements at a level of 10 volts per meter, at
frequencies from 26 MHz to 1 GHz, and the ESD requirements of
this standard. However, even at this level of device immunity,
certain transmitting devices (cellular phones, walkie-talkies,
cordless phones, paging transmitters, etc.) emit radio frequencies
that could interrupt ventilator operation if operated in a range too
close to the ventilator. It is difficult to determine when the field
strength of these devices becomes excessive. Practitioners should
be aware that radio frequency emissions are additive, and that the
ventilator must be located a sufficient distance from transmitting
devices to avoid interruption. Do not operate the ventilator in a
magnetic resonance imaging (MRI) environment. This manual
describes possible ventilator alarms and what to do if they occur.
Consult with your institutions biomedical engineering
department in case of interrupted ventilator operation, and before
relocating any life support equipment.
