1 Introduction

1.1 What’s Aeon7400A?

Aeon7400A is a compact and integrated anesthesia transmitting system. The
breathing machine not only provides patients in operation with IPPV ventilation, but
also monitors and displays the patient’s various parameters. The ventilator used in
the system is controlled by a microprocessor. Aeon7400A is intended for use in the
operating room and emergency department of hospital.

Not all the optional functions available may be included in the manual. It is also
possible to add other equipment to the top or middle of this system for added
functions. For more information with respect to the existing product, please feel free
to contact the local representatives.

WARNING: The user of Aeon7400A must be professional and trained.

WARNING: Aeon7400A is unsuitable for use in a magnetic resonance

imaging (MRI) environment.

1.1.1 Intended Use

Aeon7400A is applicable for patients of over 25Kg with standard configuration.

WARNING: Aeon7400A is not to be used for infant anaesthesia.

WARNING: To avoid explosion hazards, flammable anesthetic agents

such as ether and cyclopropane shall not be used in this
anesthetic workstation. Only anesthetic agents which
comply with the requirements for non-flammable
anesthetic agents as specified in this manual.
Halothane, Desflurane, Sevoflurane, Enflurane, and
Isoflurane have been found to be non-flammable agents.

WARNING: Independent means of ventilation (e.g. a self-inflating

manually powered resuscitator with mask) should be
available whenever the anesthetic system is in use.

WARNING: Do not use antistatic or electrically-conductive breathing

tubes and mask.

WARNING: Leakage and douse of liquid, such as anesthetic agent,

bring on dangerous states or malfunctions inside device.
