Mainstream EtCO2 sensors are used to measure the carbon dioxide (CO2) levels in a patient's breath during anesthesia or ventilation procedures. Unlike sidestream sensors, mainstream sensors are directly integrated into the patient's breathing circuit and are located at the airway's proximal end. This allows for real-time and accurate monitoring of CO2 levels without the need for sampling tubes or additional components.

Types of Mainstream EtCO2 Sensors

EtCO2 Mainstream VS Sidestream

  • EtCO2 mainstream and sidestream are two types of capnography systems used in healthcare. Mainstream capnography involves directly measuring exhaled carbon dioxide levels through a sensor attached to the patient's endotracheal tube or airway adapter. In contrast, sidestream capnography uses a sampling tube to draw a sample of expired gas from the patient's airway, which is then analyzed for carbon dioxide levels.

  • Mainstream capnography offers real-time, accurate measurements but requires a larger sensor and can cause patient discomfort. Sidestream capnography is less intrusive but may have a slight delay in measurement and potentially encounter technical issues related to sampling.

FAQs of Mainstream EtCO2 Sensors

  • What is mainstream EtCO2?

    Mainstream EtCO2 refers to the direct measurement of end-tidal carbon dioxide levels within the patient's airway using a sensor attached to the respiratory circuit.

  • What are the advantages of mainstream capnography?

    • Real-time and continuous monitoring of end-tidal carbon dioxide (EtCO2) levels.

    • Accurate and reliable measurements of EtCO2.

    • Immediate detection of changes in respiratory status and ventilation effectiveness.

    • Less risk of sampling errors and delays compared to sidestream capnography.

  • Which sensor is used for capnography monitoring?

    The main sensor used is an infrared carbon dioxide (CO2) sensor. This sensor uses infrared light to measure the concentration of exhaled CO2 and provides real-time data on end-tidal carbon dioxide (EtCO2) levels, waveform, and other parameters during respiration.
