Abstract: This article presents a dynamic parameter calibration method and device for a ventilator tester. Temperature, humidity, pressure, and flow waveforms during a single human respiratory cycle are acquired using sensors and a digital acquisition system. Corresponding mathematical models, including respiratory flow, temperature, humidity, and pressure models, are established. Based on these models, an active piston mechanism is adopted to accurately simulate the dynamic respiratory parameters of the human body, thereby calibrating the ventilator tester. The proposed method effectively improves the reliability and accuracy of clinical ventilator calibration results.
