Intended use
The Aespire anesthesia system is a compact, integrated, and intuitive
anesthesia delivery system. The 7900 Ventilator provides mechanical
ventilation for patients during surgery as well as monitoring and
displaying various patient parameters.
The 7900 Ventilator uses a microprocessor-controlled ventilator with
internal monitors, electronic PEEP, Volume Mode, and other optional
features. A serial interface permits communication to external
monitoring.
This anesthesia system is not suitable for use in an MRI environment.
This system must only be operated by medical personnel authorized
and trained to use this product. It must be operated according to the
instructions in this User’s Reference manual.
Note Configurations available for this product depend on local market and
standards requirements. Illustrations in this manual may not
represent all configurations of the product. This manual does not
cover the operation of every accessory. Refer to the accessory
documentation for further information.

ACGO
Fresh gas flow with anesthetic agent is directed through the Auxiliary
Common Gas Outlet (ACGO) on the front of the system when the
ACGO switch is in the ACGO position. Mechanical ventilation is not
available when operating an auxiliary manual breathing circuit with
fresh gas from the ACGO. The Bag/Vent switch, APL valve, and bag
arm are not part of the external circuit. Volume and pressure
monitoring are not available.
O2 monitoring of fresh gas is available automatically when the ACGO
is selected. A sample of the fresh gas is diverted to the O2 cell in the
breathing system. The sample flow to the O2 cell is dependent on the
pressure in the external circuit. The sample flow reduces the fresh
gas flow rate to the auxiliary breathing circuit equal to the amount
delivered to the O2 cell.
Fresh gas oxygen concentration is displayed on the screen. Set the
alarm limits appropriately. Note that fresh gas oxygen concentration
may not reflect FiO2 during spontaneous breathing or in rebreathing
circuits.
Important Use an external O2 monitor if using a rebreathing circuit on ACGO.
Do not use an external ventilator on the ACGO. Do not use the ACGO
to drive external ventilators or for jet ventilation.
See “Scavenging” in the “Setup and Connections” section for more
information on connections.
WARNING The maximum pressure at the ACGO can be up to 55 kPa
(8 psi). Use a breathing circuit with pressure relief.

Scavenging the
ACGO sample flow
A sample of the fresh gas is diverted to the O2 cell in the breathing
system to show the O2 numerics on the monitor display. This sample
flow should be scavenged when an auxiliary manual breathing circuit
is used with N2O or volatile anesthetics.
If scavenging is not connected, the sample flow is emptied into the
room.
To connect the scavenging:
1. Attach a circle breathing circuit to the inspiratory and expiratory
ports.
2. Occlude the circle circuit by connecting the Y-piece to the plug
located to the rear of the expiratory port.
3. Check for clinically correct settings.
4. Check the position of the Bag/Vent switch:
• If the Bag/Vent switch is set to mechanical ventilation mode,
the bellows fills slowly with the sample flow. When the
bellows is full, the sample flow goes to the AGSS
(Mechanical ventilation does not start when ACGO switch is
set to ACGO).
• If the Bag/Vent switch is set to bag mode, set the APL valve
to MIN and attach a bag. The bag fills slowly with the sample
flow. When the bag is full, the sample flow goes to the AGSS.
Scavenging from an
auxiliary manual
breathing circuit
Important Do not use these connectors as an outlet for exhaust flow.
Scavenging a gas
monitor sample flow
Scavenge the exhaust if an auxiliary manual breathing circuit is used
with N2O or volatile anesthetics.
An auxiliary inlet is available for active and passive AGSS units. It
provides a female connection with 30 mm male - 30 mm male
connector (or a 30 mm male - 19 mm male connector) into the
auxiliary port under the breathing system.
The auxiliary inlet is a convenience inlet to the air brake of active
AGSS units. There is a reservoir to capture exhaust flows higher than
the extract flow.
A separate exhaust hose is needed from the auxiliary manual
breathing circuit to the disposal point for all AGSS units.
Sample gas from a gas monitor can be scavenged using the sample
gas return port or the AGSS. To scavenge from a gas monitor using
the sample gas return port, connect the tubing from the monitor to the
sample gas return port. To scavenge from a gas monitor using the
AGSS, connect tubing from the monitor to the male luer inlet on the
bottom of the AGSS underneath the breathing system.
