Auxiliary Common Gas Outlet
Use the optional Auxiliary Common Gas Outlet (ACGO) switch to
direct the fresh gas flow through the ACGO port on the front of the
system. The ACGO may be used to provide fresh gas to an auxiliary
manual breathing circuit.
Mechanical ventilation is not available when using 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 if the system has the airway module option or the O2 cell
monitoring option. Systems with both an airway module and an O2
cell will display the circuit O2 value obtained from the airway module.
WARNING The Bag/Vent switch and the APL valve do not control the
ACGO or any breathing circuit connected to the AGCO.
Do not use these controls when using a breathing circuit
with fresh gas from the ACGO. Patient injury may occur.
w Volume and pressure monitoring are not available
through the system when using the ACGO port. Monitor
the patient using other methods.
w Do not use an external ventilator on the ACGO. Do not
use the ACGO to drive external ventilators or for jet
ventilation.
w The maximum pressure at the ACGO can be up to 55 kPa
(8 psi). Use a breathing circuit with pressure relief.
Using the ACGO 1. Set the ACGO switch to the ACGO position.
Fresh gas flows through the ACGO port.
Fresh gas oxygen concentration is displayed on the screen.
2. Set the alarm limits to clinically appropriate settings.
3. To stop fresh gas flow through the ACGO port, set the ACGO
switch to Circle.
Note Displayed fresh gas oxygen concentration may not reflect FiO2
during spontaneous breathing or in rebreathing circuits. Use an
external O2 monitor if using a rebreathing circuit on ACGO.
Note 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 diverted to
the O2 cell.
