Objective To reduce errors in measuring of the Tidal Volume of Ventilator by Turbine Airflow Sensor. Methods Describe the construction and principle and feature and discussed the flowrate characteristics of turbine airflow sensor, indicate that there is inertia at working by its construction. According to the working feature of Ventilator and analyzing flowrate curve,provide measuring and calibrating method of Tidal Volume of Ventilator. Results Improving the measuring accuracy by adjusting quantity of the Sensor pulse and measuring subsection of the capability coefficient. Conclusion The method is effective to reduce errors in measuring of the Tidal Volume and be inspected and verified well in product development.
