Scavenging the ACGO sample flow
When the ACGO port is in use, a sample of the fresh gas is diverted
to the airway module or the O2 cell in the breathing system. This
sample is then measured and displays the O2 numerics on the
screen. This sample flow should be scavenged when N2O or volatile
anesthetics are delivered through the ACGO. If scavenging is not
connected, the sample flow will enter the room through the breathing
system. To connect the scavenging:
1. Attach a circle breathing circuit to the inspiratory and expiratory
ports.
2. Occlude the breathing circuit by connecting the wye-piece, or
patient connection, to the leak test plug located behind 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 gas flow goes to the AGSS.
(Mechanical ventilation does not start when the ACGO
switch is set to ACGO.)
• If the Bag/Vent switch is set to the bag mode, set the APL
valve to MIN, and attach a bag to the manual bag port. The
bag fills slowly with the sample flow. When the bag is full,
the sample flow goes to the AGSS.
