S/5™ Compact Anesthesia Monitor
Intended use
The Datex-Ohmeda S/5 Compact Anesthesia Monitor with L-CANE03 or L-CANE03A software is intended for
multiparameter patient monitoring with optional patient care documentation.
Indications for use
The S/5 Compact Anesthesia Monitor with L-CANE03 or L-CANE03A software is indicated for monitoring of
hemodynamic (including arrhythmia and ST-segment analysis), respiratory, ventilatory,
gastrointestinal/regional perfusion, Bispectral index (BIS), Entropy (State Entropy and Response Entropy)
and neurophysiological status of all hospital patients.
The S/5 Compact Anesthesia Monitor with L-CANE03 and L-CANE03A software when using BIS is for
monitoring the state of the brain by data acquisition and processing of electroencephalograph signals and
may be used as an aid in monitoring the effects of certain anesthetic agents.

1.4 Safety
1.4.1 Safety precautions
Warnings
WARNING A WARNING indicates a situation in which the user or the patient may be in
danger of injury or death.
Power connection
• Before connecting the power cord to the mains outlet, check that the local voltage and
frequency correspond with the rating stated on the device plate on the rear panel.
• Connect the monitor to a three-wire, grounded, hospital grade socket. Do not remove the
grounding pin from the power plug.
• Use only an intact power cord. Replace the power cord if it is cracked, frayed, broken or
otherwise damaged.
• Do not apply tension to the power cord otherwise the cord may get damaged.
• Do not use extension cords or adapters of any type.
Laser radiation
• When using the ARK Barcode Reader, N-SCAN, do not stare into beam. The N-SCAN is a
Class 2 laser product.
External connection
• Do not connect any external devices to the monitor other than those specified by Datex-
Ohmeda.
Fuse replacement
• Replace a fuse only with one of the same type and rating.
Explosion hazard
• Do not use the monitor in the presence of flammable anesthetics.
Patient safety
• Do not perform any testing or maintenance on the monitor while it is being used on a
patient.
• Use only cables and accessories approved by Datex-Ohmeda. Do not modify them. Other
cables and accessories may damage the monitor or interfere with the measurement.
• PACEMAKER PATIENTS: The impedance respiration measurement may cause rate changes
in Minute Ventilation Rate Responsive Pacemakers. In this case set the pacemaker rate
responsive mode off or turn the monitor impedance respiration measurement off.

General Service Guide
Cleaning and service
• Only trained personnel with proper tools and test equipment should perform the tests and
repairs described in this manual. Unauthorized service may void the monitor warranty.
• Turn the power off and unplug the power cord before cleaning or service. Completely remove
any moisture before reconnecting the power cord to the mains outlet.
• Do not touch any exposed wire or conductive surface while any cover is removed and the
monitor is energized. The voltages present can cause injury or death.
• NOTE! The monitor is always internally powered when the batteries are connected.
• Always perform an electrical safety check and a leakage current test on the monitor after
service.

Datex-Ohmeda S/5 Compact Anesthesia and Critical Care Monitor
Cautions
CAUTION A CAUTION indicates a condition that may lead to equipment damage or
malfunction.
Installation
• Leave space around the monitor to allow proper ventilation.
• Ensure that the module is properly orientated (i.e. module release latch facing downward)
before insertion.
Before use
• Allow two minutes for warm-up and note any error messages or deviations from normal
operation.
• Clean the fan dust filters once a month or whenever necessary.
• Do not connect a sampling line to the female Patient Spirometry connector while the other
end of the sampling line is connected to the D-fend water trap. The pressure in the gas
sampling system may cause damage to the PVX unit pressure transducer.
Autoclaving and sterilizing
• Do not autoclave any part of the monitor.
• Do not gas sterilize the modules.
Cleaning and service
• Do not use ammonia, phenol, or acetone based cleaners. These cleaners may damage the
monitor surface.
• Do not immerse the monitor in any liquid. Do not allow liquid to enter the monitor or
modules.
• Electrostatic discharge through the PC boards may damage the components. Before
handling PC boards, wear a static control wrist strap. Handle all PC boards by their non-
conductive edges and use anti-static containers when transporting them.
• Do not break or bypass the patient isolation barrier when testing PC boards.
Special components
• Special components are used in these monitors that are vital to assure reliability and safety.
Datex-Ohmeda assumes no responsibility for damage, if replacement components not
approved by Datex-Ohmeda are used.
• A lithium battery on the Central Processing Board. Dispose of the faulty IC containing the
battery according to local regulations.
Document No. M1031508

General Service Guide
Batteries
The battery packages contain Ni-MH that is hazardous to the environment and therefore needs to
be disposed of carefully according to local regulations.
To replace the batteries safely, please refer to the instructions in this manual.
• Do not short-circuit the battery terminals, this may produce a very high current, which will
damage the battery.
• Do not dispose of the battery into open flame, nor put the battery near fire, as it may
explode.
• Do not dismantle the battery. It contains electrolyte, which may damage clothing or cause
injury to skin or eyes. If exposed to electrolyte, wash the injured area with plenty of clean
water and contact a doctor.
See also section “Symbols”.
Storage and transport
Do not store or transport the monitor outside the specified temperature and pressure ranges:
Temperature -10...+50 °C/14...122 °F
Ambient pressure 660...1060 hPa/500...800 mmHg/660...1060 mbar
Humidity 10...90 % non-condensing
Disposal
Dispose of the whole device and parts of it in accordance with local environmental and waste
regulations.
The manufacturer accepts no responsibility for any modifications made to the monitor outside its
factory.

Datex-Ohmeda S/5 Compact Anesthesia and Critical Care Monitor
2 SYSTEM DESCRIPTION
2.1 Introduction
Datex-Ohmeda S/5 Compact Monitor builds up a freely configurable modular system. The
architecture is designed to enable different module combinations so that the user is able to get the
desirable parameter and feature set. This modular approach makes it possible to add new features
when they are needed.
2.2 Bus structure
The operation of Datex-Ohmeda S/5 Compact Monitor is based on two communication channels,
the CPU bus and module bus. All units, including the modules, receive power from the same power
supply unit, which is an integral part of the monitor frame.

The CPU bus is a communication channel
used only for internal data transfer. It is
based on the ISA bus used in IBM PC
computers. Data is transferred on this 16 bit
wide bus using the CPU clock frequency.
The module bus is for the parameter
modules. It bus is based on the widely used
industry standard RS-485, which uses a
differential serial method to transfer data.
This type of bus is robust and it allows
parameter modules to be inserted or
removed while the power is on. The module
bus uses a 500 kbps data transfer rate.

The RS-485 type of serial communication supports so-called multidrop or party line connections.
This means that all parameter modules connected to the module bus use exactly the same lines for
communication. The advantage of this is that all bus connectors are identical and the modules can
be connected in any order and position.
