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.

M1132382 |
Scavenging the ACGO sample flow
2 System Controls and Menus
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
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.
Do not use these connectors as an outlet for exhaust flow.
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.
