2.3 Operation
• The system shall always be used in
combination with other vital signs
monitoring devices and/or professional
human judgements of patient condition.
• To protect the patient from high airway
pressure, an upper pressure limit must
always be set. See Chapter 10 for details.
• To protect the patient, an alarm limit must
always be set for low expired minute
volume. See Chapter 10 for details.
• Only anesthetic agents recommended by
MAQUET are suitable for use.
• Anesthetic agent bottles without keying may
not be used with the system, nor is it
allowed to tamper with the keying of
anesthetic agent bottles.
• Ensure that the operating room is properly
ventilated.
• The system is not intended for use during
interhospital transportation.
• The system is not intended for use in an MR
environment.
• Antistatic or electrically conductive
breathing tubes should not be used. If such
breathing tubes are used in combination
with high frequency electric surgery
equipment, burns may occur.
• To allow for mains power disconnection,
make sure that the power cable connected
to the mains power supply remains visible
and fully accessible during patient treatment
and not obstructed in any way by ME
(Medical Electrical) equipment.
• If the integrity of the protective earth
conductor or the protective earthing system
in the installation is in doubt, unplug the
mains power cable and use battery power.
• The equipotentiality terminal is designed for
the connection of a potential equalization
conductor according to DIN 42 801 and
IEC 60601-1. The function of the
equipotentiality terminal is to equalize
potentials between the system and other
medical electrical devices that can be
touched simultaneously. The
equipotentiality terminal must not be used
for a protective earth connection.
• The anesthesia system has been designed
and tested to comply with requirements
specified in electromagnetic compatibility
standard IEC 60601-1-2. It is the
responsibility of the user to take necessary
measures to ensure that the EMC
environment in which the workstation will
be used is compatible with the requirements
of IEC 60601-1-2 and that the installation
is carried out according to the EMC
information. See Chapter 16 for details on
EMC environments. If limits are exceeded,
the accuracy and safety of the system may
be impaired. Proactive measures include,
but are not limited to, avoiding the use of
portable and mobile radio-emitting devices,
such as cellular phones and high frequency
apparatus, in the proximity of the system.
• Full performance is reached after a 15
minute warm-up. In case of an emergency,
the system can be used immediately.
• FLOW-i shall be connected to a
centre-tapped single phase supply circuit
when connected to a 240 Vac
(L1-L2-N-GND) supply in the United States.
• The breathing system can handle negative
pressures down to -200 cmH
2
O, but is not
designed to withstand pressures below that.
• The operator must not touch the patient
and any of the following parts
simultaneously:
