Mixed gas
Either Air or N2O can be selected as the balance gas. The balance
gas flow is controlled by the mixer. When Alternate O2 control is in
use, only O2 is flowing and balance gas is disabled.
The mixed gas goes from the mixer outlet through the vaporizer to
the fresh gas outlet and into the breathing system. A pressure-relief
valve sets the maximum outlet pressure.
When the total is adjusted toward the lower flow limit and the
calculated O2 flow is required to go below 100 ml, a message shows
in the gas settings area of the screen. The anesthesia system
calculates the required O2% to maintain the user-set total flow.
EZchange canister
When installed, EZchange provides a CO2 bypass mode that
permits continued ventilation during absorber canister change.
Condenser
The condenser removes water in the system that is produced from
the reaction of CO2 gas with the absorbent. When fresh gas flow
settings of less than the patient minute volume are used during
ventilation, the amount of re-breathed gases increases. More CO2
flows through the breathing system increasing the absorbent
consumption. The moisture buildup in the breathing system is also
increased.
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.
