Capnography is a medical monitoring technique that measures the concentration of carbon dioxide (CO2) in a patient’s respiratory gases, usually during anesthesia or intensive care. Capnography is used to help healthcare professionals monitor and manage a patient’s ventilation, assess the adequacy of breathing, and detect potential breathing problems.

• Capnography relies on an EtCO2 (end-tidal carbon dioxide) sensor to measure the concentration of CO2 at the end of each exhaled breath. The EtCO2 reading can be used to provide information about a patient’s respiratory rate, depth of respiration, and ventilation status.
• The accuracy of the EtCO2 sensor is critical to the accuracy of capnography readings. Factors that can affect the accuracy of the EtCO2 sensor include the patient’s respiratory rate and pattern, the presence of airway obstructions, the type of ventilation being used, and the calibration of the device.
• To maintain accurate readings, it is important to ensure that the EtCO2 sensor is properly calibrated and placed correctly on the patient. The sensor should be placed at the end of the endotracheal tube, nasogastric tube, or face mask. If the sensor is not properly placed, it may not accurately measure the concentration of CO2 in the patient’s respiratory gases.
• Additionally, the accuracy of the EtCO2 sensor can be affected by the presence of certain medical conditions, such as pulmonary edema, chronic obstructive pulmonary disease (COPD), or asthma. In these cases, capnography may not provide accurate information about the patient’s respiratory status.

Overall, the EtCO2 sensor is a critical component of capnography, and healthcare professionals should take steps to ensure that the sensor is properly calibrated and placed to maintain accuracy.
