Intended purpose (Indications for use)

The Datex-Ohmeda S/5 Anesthesia Monitor with L-ANE07 or L-ANE07A software is intended for
multiparameter patient monitoring with optional patient care documentation.

The S/5 Anesthesia Monitor with L-ANE07 and L-ANE07A software is indicated for monitoring of
hemodynamic (including arrhythmia and ST-segment analysis), respiratory, ventilatory,
gastrointestinal/regional perfusion, Entropy (State Entropy and Response Entropy) and neurophysiological
status of all hospital patients.

When the BIS module is used with the S/5 Anesthesia Monitor with L-ANE07 and L-ANE07A, it is intended
for use by personnel trained in its proper use. It is intended for use on adult and pediatric patients within a
hospital or medical facility providing patient care to monitor the state of the brain by data acquisition of
EEG signals. The Bispectral index (BIS), a processed EEG variable, and one component of the BIS module,
may be used in adults as an aid in monitoring the effects of certain anesthetic agents. The Bispectral
index is a complex technology, intended for use only as an adjunct to clinical judgement and training. In
addition, the clinical utility, risk/benefit, and application of BIS have not undergone full evaluation in the
pediatric population.

The S/5 Anesthesia Monitor with L-ANE07 and L-ANE07A software is also indicated for documenting
patient care related information.

The S/5 Anesthesia Monitor with L-ANE07 and L-ANE07A software is indicated for use by qualified
medical personnel only.

The Datex-Ohmeda S/5 Critical Care Monitor with L-ICU07 or L-ICU07A software is intended for
multiparameter patient monitoring.

The S/5 Critical Care Monitor with L-ICU07 and L-ICU07A software is indicated for monitoring of
hemodynamic (including arrhythmia and ST-segment analysis), respiratory, ventilatory,
gastrointestinal/regional perfusion and neurophysiological status of all hospital patients.

When the BIS module is used with the S/5 Critical Care Monitor with L-ICU07 and L-ICU07A, it is intended
for use by personnel trained in its proper use. It is intended for use on adult and pediatric patients within
a hospital or medical facility providing patient care to monitor the state of the brain by data acquisition of

1.2.2 ESD precautionary procedures

To avoid electrostatic charges building up, it is recommended to store, maintain and use

•

the equipment at a relative humidity of 30% or greater. Floors should be covered by ESD
dissipative carpets or similar. Non-synthetic clothing should be used when working with
the component.

• To prevent applying a possible electrostatic discharge to the ESD sensitive parts of the

equipment, one should touch the metallic frame of the component or a large metal object
located close to the equipment. When working with the equipment and specifically when
the ESD sensitive parts of the equipment may be touched, a grounded wrist strap
intended for use with ESD sensitive equipment should be worn. Refer to the
documentation provided with the wrist straps for details of proper use.

ESD precautionary procedure training

It is recommended that all potential users receive an explanation of the ESD warning symbol
and training in ESD precautionary procedures.

The minimum contents of an ESD precautionary procedure training should include an
introduction to the physics of electrostatic charge, the voltage levels that can occur in normal
practice and the damage that can be done to electronic components if they are touched by an
operator who is electrostatically charged. Further, an explanation should be given of methods
to prevent build-up of electrostatic charge and how and why to discharge one’s body to earth
or to the frame of the equipment or bond oneself by means of a wrist strap to the equipment or
the earth prior to making a connection.

2 System description

2.1 Introduction

Datex-Ohmeda monitors build 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 monitors is based on two communication channels, the CPU
bus and module bus.

In the 5-Module Central Unit, PC boards receive power from the F-CPU power supply and the
parameter modules receive power from a separate power supply in the 5-Module Frame unit.
These power supplies are both fed by the N-AC Power Unit. In the 8-Module Central Unit, F-CU8,
all PC boards connected to the CPU bus, as well as the parameter modules attached to the
module bus receive power from the same power supply, which is an integral part of the Central
Unit, F-CU8.

Figure 2 General bus structure of S/5 system

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 used to connect the parameter modules to the Central Unit. The bus is based
on the 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 and can be used for longer
distances than the CPU bus, e.g. for external frame connections.

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.

2.3 Distributed processing

A system assembled from Datex-Ohmeda products is a multiprocessor system. All parameter
modules have their own microprocessor, which performs functions such as module key
control, waveform filtering, parameter related computing and pneumatic control, etc. At the
same time the main CPU performs higher level tasks such as trending and alarm control. While
the parameter modules and CPU are performing their tasks, the UPI (Universal Peripheral
Interface) microprocessor handles all functions needed to transfer data between the
parameter modules and the CPU. At the same time the Display controller microprocessor
performs pixel calculations for graphics.

Figure 3 Distributed processing in S/5 system

This kind of parallel processing gives one major advantage to centralized processing. When
new parameter modules or PC boards are added to the system, the processing power is
increased. As a result, the system does not slow down when new features are added.

2.4 Module communication

The communication master controlling data transfers between the CPU and parameter
modules is called UPI processor. It sends data to each connected module 100 times a second.
Modules respond to each data request immediately by sending a data package, whose length
depends on the type of the module. This communication protocol ensures that each module
receives and sends data every 10 ms. If a module does not respond to data requests, the UPI
processor presumes that the module is disconnected.

Parameter modules may hold a static (fixed) or dynamic address, which the UPI processor uses
when sending out data. Two parameter modules of the same type must not be fitted onto the
same monitor since they might reply to a data request simultaneously, thus causing
communication errors.
