This new anesthesia gas monitor is specifically designed to measure the concentration of anesthetic agents output from vaporizer units in real time. It accurately detects commonly used volatile anesthetics such as isoflurane, sevoflurane, and desflurane using high-precision infrared analysis technology, ensuring that the actual output concentration aligns with the set values. By providing continuous monitoring of vaporizer performance, it helps clinicians identify dosage deviations or equipment malfunctions promptly. This device is well-suited for use in operating rooms, anesthesia equipment maintenance, and educational or research settings, serving as a valuable tool to enhance the safety and controllability of the anesthesia process.
