| Abstract: | In this paper, a newly-designed device is introduced, which uses non-dispersive infrared absorption technique to acquire anesthesia gas concentration signal and to perform side-stream measurement in the air way. The microcontroller is adopted to implement data acquisition, data processing and then to transmit the data to the PC screen, thus the real-time continuous invasive concentration monitoring of the anesthesia gas in the patient's respiratory air can be realized during a surgical operation. |
