EtCO2 module for multi-parameter monitor
CM2200 Wuhan Cubic Optoelectronics


  • Measured parameter:



It is designed by the principle of infrared absorption spectroscopy for the determination of the concentration of carbon dioxide at the end of an exhaled breath, which is widely used to monitoring the respiratory end tidal CO2 concentration and respiration rate. It is easy to be integrated to the monitors or anesthesia machines with an 8-pin socket and the preparation of the corresponding display/control software.

●Fast response, long-lasting life, high accuracy due to NDIR Sensor
●Be widely used for the technology of the compensation of high accuracy temperature and pressure
●EMI system can be against the interference of electromagnetic
●Compatible with Respironics CapnoStat5 or CPT Protocols. TTL and R232 can be optional
●Auto calibration function to wipe off the drift from temperature, pressure and inconsistent component
●Clinical waveform recognition ability is stronger
●Low power consumption and small size

●Clinical anesthetic machine
●CACR, PACU, ICU, pre-hospital resuccue
