ILCA is a gas measuring module for N2O, CO2 and the anaesthetic gases
Halothane, Enflurane, Isoflurane, Desflurane and Sevoflurane. ILCA con-
forms to the measurement accuracy specified by ISO-standard.
The gas measuring module cannot automatically recognise the anaesthetic in
use. The anaesthetic in use must be pre-selected, otherwise the gas measur-
ing module will measure incorrectly.
The ILCA gas measuring module principally comprises the following compo-
nents:
– Sensor head with optic and electronics
– Pump
– Pneumatic low pass
– Solenoid valve for zero calibration
– Module rack with 4 PCBs
– Solenoid valve for measuring mode switch-over (fresh gas/patient gas)
The sensor head houses 2 PCBs with the following functions:
– Pre-amplifier PCB for the two multi-channel detectors
– Base PCB with emitter activation, temperature regulation, absolute pres-
sure measurement and a serial EEPROM holding the serial number, set-
ting and calibration data for operation of the sensor head.
