CO2 module for multi-parameter monitor M402D

Product Application Built-in Side stream CO2 module of the gas measurement module is based on the principle of characteristic absorption of non-dispersive infrared light of specific wavelengths by gas molecules. Using infrared light to project gas in the respiratory airway and use infrared detectors to detect the infrared light absorption of the gas in the airway. Then through specific hardware circuits and algorithms to get the end-breathing gas concentration, inhaled gas concentration, respiration rate and other related parameters. The module uses dual-channel optical acquisition to improve the reliability of the system, and uses a variety of compensation techniques. For example, atmospheric pressure and temperature compensation, etc. that to improve the accuracy of gas concentration measurement. Product Features Provides real-time data of EtCO2, InsCO2, Capnogram and Respiration Rate Supports monitoring patients with high respiration rates, up to 150 rpm Supports intubated and non-intubated patients Sensitive CO2 detection, can detect minimum 1 vol% CO2 change Low rise-up Time (< 180ms), Response Time below 2s Long continuous working time (depending on model) Wide range of gas measurement (0 ~ 20%) Sensors for Software and Hardware status Capnogram data Automatic zeroing Water trap preventing water and secretion intrusion or microstream sampling line Simple interfacing with RS232 serial interface, TTL levels Accuracy according to the requirements of ISO 80601-2-55:2011 For OEM version, can be delivered with compatible communication protocols
