Page 84: Ezchange Canister Mode
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.
Page 85: Using Ezchange Canister Mode
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.
Page 86: Condenser
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.
Page 87 3 Operation Push the drain button to empty any water in the condenser. 3-39 2067226-001...
Page 88: Auxiliary Common Gas Outlet
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.

Page 244: Vaporizer
Aisys CS² Vaporizer The electronically controlled vaporizer consists of the internal electronic control unit and the Aladin agent cassette. The agent cassettes are color coded, have indexed filling ports, and are magnetically coded for each agent. The electronic control unit governs the flow through the agent cassette and the agent concentration in the fresh gas flow.

No other Aladin cassettes have electronic level sensing. The agent level shows graphically in the agent settings area of the screen.
Page 246 Aisys CS² When electronic level sensing is unavailable for an Aladin cassette, the agent level unknown symbol shows in the agent settings area of the screen. In this case, refer to the liquid level indicator. There are three types of Aladin cassette filler systems. Halothane, enflurane, and isoflurane use color-coded, keyed fillers.

Page 250: Installing A Cassette
Aisys CS² Installing a cassette Using the liquid level indicator, check that the cassette is filled to the appropriate level. If using Aladin2, unlock the cassette handle before installing it in the active bay. Insert the cassette into the active bay until a click is heard, ensuring the cassette is in the correct position.

13 Vaporizer cassettes Cassette maintenance Clean and drain the cassettes as recommended. Cleaning CAUTION Do not wipe the cassette with alcohol or alcohol-based detergents. This may damage the surface of the cassette. Remove the cassette from the system. Clean the cassette surface with a cloth moistened in a mild soap solution.
Page 252: Draining Halothane Cassettes
Aisys CS² Draining halothane cassettes The decomposition of halothane causes the release of halides, which may corrode metal components particularly in the presence of moisture. A preservative, added to halothane by its manufacturers to impede decomposition, can leave a residue which may cause cassette components to stick.

Page 261 13 Vaporizer cassettes WARNING Do not store filled or partially filled desflurane cassettes above the normal working temperature of 35C/95F. Storage at high temperature may cause the overpressure valve to vent desflurane vapor into the ambient air. • Do not open or press the cassette filling port or the gas connection valves with fingers or any kind of instrument.
