Aisys CS² EZchange canister mode Use the optional EZchange canister mode for continued ventilation of the patient while changing the absorber canister. The EZchange canister mode seals the breathing circuit when the canister holder is down. While the absorber canister is out of the breathing circuit, the patient re-breaths exhaled gases without any gas passing through the absorbent.
3 Operation Using EZchange canister mode Note Make sure that the absorber canister has side rails. If the canister does not have side rails, it will not work in the EZchange canister holder. Push the absorber canister release to activate the EZchange canister mode.
Aisys CS² Condenser Use the optional condenser to remove water in the system that is produced from the reaction of CO2 gas with the absorbent. The condenser is connected between the outlet of the absorber canister and the inlet of the circuit module. Moisture in the gas is condensed into water droplets, which run into the condenser’s reservoir.

Aisys CS² 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.
Page 89
3 Operation 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.

Allow the reading to stabilize, then select Done. Calibrate the O2 cell if necessary. External gas monitor When External Gas Monitor is set to Yes by the Super User, the External Gas Monitor reminder occurs.
Aisys CS² Individual tests The Full Test or all of the individual tests must be completed with passing results at least once within every 24-hour period. Individual tests allow the user to perform any combination of single tests. These tests are helpful if there is a specific problem/alarm and the user wishes to test only that portion of the system.
5 Preoperative tests To run this test, follow the on-screen instructions. Low P leak (machines with ACGO) The negative Low P Leak measures machine leaks before the breathing system, between the common gas outlet and the high- pressure pneumatics and includes the gas mixer and vaporizer. It measures low pressure pneumatic leaks with a pass or fail limit of 50 Note Any cassette may be used during the check.
Aisys CS² Positive low pressure leak test (ACGO systems only) Note For ACGO machines, perform either a negative Low P Leak test or a positive low-pressure leak test depending on local requirements. CAUTION Do a positive-pressure leak test at the ACGO port only. Connect the leak test device to the ACGO port with the positive- pressure leak test adapter.

To access the Spirometry menu, push the Spirometry button and then select Setup Loops. Data source Several monitoring parameters can be obtained from the ventilator or the airway module.
6 Airway modules Automatic agent identification Airway modules with agent identification automatically identify Halothane, Enflurane, Isoflurane, Sevoflurane, and Desflurane. The inspiratory and expiratory concentrations of the agent appear in the digit field or the agent waveform field if selected. Minimum concentration for the identification is 0.15% volume. The agent selection remains active even if the concentration decreases below 0.15% volume during the case.
Aisys CS² Calibrating the airway module Calibrate airway modules once every six months or whenever there are indications of errors in the gas readings. Use a manufacturer approved calibration gas and regulator to calibrate the modules. See the "Parts" section for the stock numbers of the calibration gas and regulator.
Aisys CS² Alarms Alarms may be high priority, medium priority, or low. When an alarm occurs during a case, an alarm tone sounds and the alarm message is displayed in the alarm message field.

8 Setup and connections Turn off the auxiliary O2 flowmeter and venturi suction. Open the cylinder. Record the cylinder pressure. Close the cylinder. If the cylinder pressure decreases more than 690 kPa (100 psi) in one minute there is a significant leak. To repair a leak, install a new cylinder gasket and tighten the adapter.
Aisys CS² Attaching equipment to the top of the machine WARNING The top of the machine has a weight limit of 45 kg (100 lb). • Check the stability of the system in its final configuration. Make sure the weight is evenly distributed throughout the system.
8 Setup and connections Passive AGSS WARNING Always verify the proper operation of any gas scavenging system. Make sure that the scavenging system is not occluded. The optional passive anesthesia gas scavenging system (AGSS) is for use in operating room environments that do not have an active gas extraction system for waste gas disposal.
Aisys CS² Active AGSS WARNING Always verify the proper operation of any gas scavenging system. Make sure the scavenging system is not occluded. There are several versions of the optional active Anesthesia Gas Scavenging System (AGSS) available depending on the hospital’s type of waste gas disposal system.
8 Setup and connections Connect the proper hose to the AGSS outlet connector on the bottom of the AGSS underneath the breathing system. Attach the other end of the hose to the hospital disposal system. With the AGSS operating, verify that the ball on the flow indicator rises to the green zone, indicating adequate flow.

11 Specifications and theory of operation Ventilator theory The ventilator pneumatics are at the rear of the breathing system. A precision valve controls gas flow to the patient. During inspiration, this gas flow closes the exhalation valve and pushes the bellows down.
Aisys CS² The voltage from the cell cartridge is affected by the temperature of the monitored gas mixture. A thermistor in the cell’s housing automatically compensates for temperature changes in the cell. O2 monitoring uses signal processing and analyzing circuitry to convert the cell signal into a corresponding percent oxygen value.
