CapnoSET® Mainstream EtCO2 measurement is easy to use and low cost of use, and is widely used in various clinical scenarios, including surgical monitoring, ICU, and emergency monitoring and transport monitoring that may be outside the hospital. Such as plug and play in emergency monitoring, transport monitoring scenarios, 0 warm-up time is a very important technical requirement. Based on a large number of clinical practices and core technology research and verification, Witleaf has released CapnoSET® mainstream rapid response technology, realizing the clinical application requirements of plug and play without warm-up.

The breathing gas of the human body is saturated with water vapor, when the ambient temperature is low, for the mainstream EtCO2 measurement, it will condense on the surface of the measuring gas chamber to form water droplets, resulting in the scattering of infrared light through the measurement chamber resulting in overestimation of EtCO2 concentration, wSmartGas® through CapnoSET® mainstream airway adaptor technology by adjusting the incidence angle of IR light incidence surface to avoid the scattering of IR light in the penetration measurement air chamber to ensure the accuracy of measurement；

The period from start-up to stable operation of mainstream EtCO2 monitoring equipment is the rapid change of internal working conditions of the equipment, including temperature change, baseline change, radiation power of the IR light source and change of IR detector sensitivity.
