NDIR Sidestream EtCO2 Sensor
MED-CD1002MED-CD1002

Cubic MED-CD1002 is a sidestream EtCO2 sensor based on advanced non-dispersive infrared (NDIR) technology, designed for continuous measurement of end-tidal carbon dioxide (CO2) concentration in respiratory care applications. The sensor provides real-time EtCO2 and respiratory rate measurements for capnograph waveform generation to support accurate ventilation assessment and early detection of respiratory abnormalities. With fast response time, high measurement accuracy, and excellent long-term stability, MED-CD1002 provides reliable performance across demanding clinical environments.

The compact modular architecture and standard UART interface of MED-CD1002 enable easy OEM integration into a wide range of medical devices, including EtCO2 monitors, ventilators, patient monitors, anesthesia machines, and other respiratory care systems.
