-
Sidestream CO2 Module is intended for continuous noninvasive monitoring of inspired CO2 (FiCO2) and end tidal CO2 (EtCO2), respiration rate (RR) and apnea
-
Supports intubation confirmation, weaning, CPR effectiveness, leak detection, and hypermetabolic state monitoring
-
No calibration needed, module is ready to deliver accurate readings immediately after warm-up
-
Adjustable flow rate (50–250 ml/min) with ±10% accuracy ensures consistent waveform quality
-
Stable performance even in the presence of anesthetic vapors, humidity, and other gases
