Important Safety Information
Operator's Responsibility for Patient Safety
For correct and effective use of the product and in
order to avoid hazards it is mandatory to carefully
read and to observe all portions of this manual.
The design of the intensive care ventilators this device
is intended to be used with, accompanying literature,
and the labeling on the equipment take into considera-
tion that the purchase and use of the equipment are
restricted to trained professionals, and that certain
inherent characteristics of the equipment are known to
the trained operator. Instructions, warnings, and
caution statements are limited, therefore, largely to the
specifics of the Draeger design. This publication
excludes references to various hazards which are
obvious to a medical professional and operator of
respiratory care equipment, to the consequences of
misuse of such equipment, and to potentially adverse
effects in patients with abnormal conditions. Product
modification or misuse can be dangerous. Draeger
Medical, Inc. disclaims all liability for the consequences
of product alterations or modifications, as well as for
the consequences which might result from uses of the
product not covered by its intended use or from the
combination of this product with other products whe-
ther supplied by Draeger or by other manufacturers if
such a combination is not endorsed by Draeger Medi-
cal, Inc..
The operators of ventilator systems must recognize
their responsibility for choosing appropriate safety mon-
itoring that supplies adequate information on equipment
performance and patient condition. Patient safety may
be achieved through a wide variety of different means
ranging from electronic surveillance of equipment
performance and patient condition to simple, direct
observation of clinical signs. The responsibility for the
selection of the best level of patient monitoring lies
solely with the equipment operator.
