Sidestream CO2 sensor is intended for continuous noninvasive monitoring of fraction of inspired CO2 (FiCO2) and end tidal CO2 (EtCO2), respiration rate (RR) and apnea.
Specially designed for implementation into medical devices for anesthesiology, intensive care, as well as patient monitors.
Anesthesiology and intensive care departments of professional medical facilities, transportation within professional medical facilities
- Easy integration.
- Standard accessories.
- No routine calibration.

- Assessing of the spontaneous breathing adequacy. Using the capnography the level of spontaneous breathing during recovery after anesthesia can be
- Weaning from mechanical ventilation;
- Controlling of breathing system hermetic seal. A gas leakage is always possible during anesthesia. The leakage can be detected by ЕtCO2 monitoring, which
- value is gradually increasing due to hypoventilation;
- Examination of circulatory arrest and resuscitation procedures effectiveness;
- Capnometry is optimal method for monitoring of cardiopulmonary resuscitation (CPR) effectiveness;
- Control during the trachea intubation;
- Examination of ventilation-perfusion ratio mismatch;
- Any cause that reduces the lungs perfusion and/or increases the respiratory dead space can lead to PEtCO2 decreasing and ΔP(a-Et)CO2 increasing.
- Monitoring of hypermetabolic conditions (malignant hyperthermia, thyroid crisis, sepsis, etc.).
