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.

Sidestream sensors provide continuous monitoring of CO2 levels, allowing healthcare professionals to assess ventilation effectiveness and the patient's respiratory status, commonly used in critical care units and during procedures where endotracheal intubation is not required.

Types of Sidestream ETCO2 Sensors

How does Sidestream EtCO2 Sensor Work?

  • Sidestream EtCO2 sensors work by using a sampling tube to draw a small sample of exhaled gas from the patient's airway. This sample is then transported to the sensor for analysis and measurement of carbon dioxide levels. The sampling tube is connected to the patient's airway through an adapter or cannula. A small pump or vacuum within the capnography system helps to draw the gas sample through the tube to the sensor. Once the sample reaches the sensor, it analyzes the carbon dioxide concentration and provides the EtCO2 reading.

  • Sidestream capnography requires a small amount of gas flow to be diverted from the patient's airway, leading to a slight delay in measurement compared to mainstream capnography.

FAQs of Sidestream EtCO2 Sensors

  • What is sidestream EtCO2?

    Sidestream EtCO2 refers to the measurement of end-tidal carbon dioxide levels by sampling a small portion of exhaled gas through a sampling tube located away from the patient's airway.

  • What is the flow rate of sidestream capnography?

    Typically, the flow rate of sidestream capnography is around 50-200 milliliters per minute (mL/min).

  • What are the advantages of sidestream capnography?

    • Non-intrusive and less uncomfortable for patients compared to mainstream capnography.

    • Provides flexibility in terms of sensor placement and can be used with various airway adapters.

    • Can be used in a wide range of clinical settings and patient populations.

    • Offers reliable and accurate measurements of end-tidal carbon dioxide levels.

    • Allows for continuous monitoring of ventilation and respiratory function.

  • What is the difference between sidestream and mainstream ETCO2 capnography?

    Sidestream ETCO2 samples exhaled air through a tube, while mainstream ETCO2 measures CO2 directly from the airway. Mainstream has faster response and lower contamination risk. Choose based on patient needs and monitoring requirements. Read further: mainstream vs sidestream capnography
