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.
