What is S/5 Aespire?
The S/5 Aespire is a compact, integrated and intuitive anesthesia delivery
system. The ventilator portion provides mechanical ventilation for patients
during surgery as well as monitoring and displaying various patient
parameters.
The system uses a microprocessor-controlled ventilator with internal
monitors, electronic PEEP, Volume Mode, and other optional features. A serial
interface permits communication to cardiovascular and respiratory gas
monitoring.
Illustrations in this manual may not cover all types of options available. Other
equipment may be attached to the system on the top shelf or on the side
dovetail rails. Consult with your Datex-Ohmeda representative for details
about systems available in your location.
The S/5 Aespire is not suitable for use in an MRI environment.

Item Description
1Auxiliary Common
Gas Outlet switch
(ACGO)
Sends fresh gas to the ACGO when the switch is
activated. The ACGO may be used to provide fresh
gas to an external manual breathing circuit.
Mechanical ventilation is not available when the
auxiliary outlet is selected and a medium priority
alarm will sound and a message “Aux Gas Outlet On”
is displayed. Pressure and volume monitoring are
not available when the ACGO is selected. Fresh gas
oxygen monitoring is available when the ACGO is
selected.
The ACGO should not be used to drive external
ventilators or for jet ventilation.
Breathing system selected:
Auxiliary outlet selected:
4 & 7 Flow sensor or flow
port adapter
Flow sensors provide volume measurements for
some monitoring functions. Flow port adapters have
no measurement capabilities.
Systems with volume monitoring but without volume
compensation have a flow port adapter in the front
position of the flow sensor module (inspiratory) and
a flow sensor in the rear position (expiratory).
Systems without volume compensation and without
volume monitoring have flow port adapters in both
positions of the flow sensor module. All other
systems have flow sensors in both positions of the
flow sensor module.

6Canister release Push to remove the canister. This allows the
breathing system to vent to the room. Be sure to hold
the canister by the handle before releasing the
canister.
Note: Always do a leak test after operating the
canister release.
12 APL valve Adjusts breathing system pressure limit during
manual ventilation. The scale shows approximate
pressures. Above 30 cm H2O, you will feel clicks as
the knob turns. Turn clockwise to increase. The
following example setting is at about 20 cm H2O:

• Mechanical ventilation is not available.
• The pressure gauge, Bag/Vent switch, APL valve, and bag arm are not
part of the external circuit.
• Volume and pressure monitoring are not available.
•O

selected if the system has the O2monitoring option.

• Fresh gas oxygen concentration is displayed on the ventilation screen.
Set alarm limits appropriately. Note that fresh gas oxygen concentration
may not reflect FiO2in rebreathing circuits such as the Mapleson series.
Use an external O2monitor if using a rebreathing circuit on ACGO.
•Asample of the fresh gas is diverted to the O2cell in the breathing
system.
• The sample flow to the O2sensor is dependent on the pressure in the
external circuit. The sample flow reduces the fresh gas flowrate to the
external breathing circuit as shown in the graph.
• Do not use an external ventilator on the ACGO.
• Do not use the ACGO to drive external ventilators or for jet ventilation.
Estimate the mean pressure required for ventilation and determine a mean
sample flow rate from the graph:
Figure 2-4 • Back pressure (cm H20) vs. flow to O2sensor (L/min)
Scavenging the ACGO
sample flow
If the external manual breathing circuit is to be used with N2O or volatile
anesthetics, the sample flow should be scavenged.
1. Occlude the patient circuit of the breathing system by using the leak test
plug located to the rear of the expiratory port.
2. Check for clinically correct settings. Set the Bag to Vent switch to the
ventilator mode. Alternatively set the Bag to Vent switch to the bag mode
and set the APL to MIN and attach a bag.
3. The bellows, or bag, will fill slowly with the fresh gas sample flow and then
spill to the AGSS.

Scavenging from the
external manual
breathing circuit
If the external manual breathing circuit is to be used with N2O or volatile
anesthetics, the exhaust should be scavenged.
An auxiliary inlet is available for active AGSS units. It provides a 30 mm male
connection 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.
For all AGSS, a separate exhaust hose is necessary from the external manual
circuit to the disposal point.

maintenance manual for more detailed information on the vaporizer.
