Sidestream EtCO2 Sensors

Sidestream EtCO2 sensors are used to measure the carbon dioxide (CO2) levels in a patient's breath during anesthesia or ventilation procedures. These sensors are located separate from the patient's airway and are connected to the breathing circuit through a sampling tube. They draw a small sample of the patient's exhaled breath away from the airway and analyze it to determine the CO2 concentration.
