Nasal Flow and Gas Sampling

This product is a medical device that combines nasal oxygen supply and end-expiratory gas sampling. It continuously collects end-expiratory carbon dioxide (EtCO₂) samples through a nasal catheter while providing oxygen supply, enabling real-time monitoring of the patient's ventilation status and respiratory rate. It is suitable for scenarios such as anesthesia monitoring, ICU, emergency care, and post-operative recovery, especially for patients without intubation. It can help medical staff detect abnormalities such as insufficient ventilation, airway obstruction, or respiratory depression early on without interrupting oxygen therapy, and assist in determining whether ventilation is adequate and changes in circulatory status.
