Aespire 7900
What is an Aespire 7900? The Aespire 7900 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 Aespire 7900 is not suitable for use in an MRI environment.

Description Auxiliary 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:

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:

ACGO

When you operate a breathing apparatus with fresh gas from the ACGO: • 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. • O2 monitoring of fresh gas is available automatically when the ACGO is selected if the system has the O2 monitoring option.
1009-0632-000
2 System Controls and Menus • Fresh gas oxygen concentration is displayed on the ventilation screen. Set alarm limits appropriately. Note that fresh gas oxygen concentration may not reflect FiO2 in rebreathing circuits such as the Mapleson series. Use an external O2 monitor if using a rebreathing circuit on ACGO. • A sample of the fresh gas is diverted to the O2 cell in the breathing system. • The sample flow to the O2 sensor 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:

Scavenging the ACGO sample flow
If the external manual breathing circuit is to be used with N 2O 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 N 2O 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.
