Sidestream monitoring is a good option for non-intubated spontaneously breathing patients as well as patients requiring intubation during short-term procedural sedation or anaesthesia. LoFlo sidestream EtCO2 sensors use a common extension server, providing clinical versatility to use with the same monitor. No calibration is required. The sensors remain stable over time with continual and automatic validated calibration information. This product is the replacement for Legacy 989803144471
