摘　　要：目的为便携式肺功能仪提供经济、有效的质量控制测量方法,保障便携式肺功能仪测量性能的质量可控。方法参考国家计量校准规范的实验测量方法,并依据其技术要求作为质量控制测量结果的判定依据,应用有创呼吸机、标准呼吸模拟器两种测量设备进行实验分析和比较。结果本测量方法经理论分析、实验及结果验证,能科学、可行地应用于便携式肺功能仪的肺活量、用力肺活量、最大分钟通气量三种参数的质量控制测量。结论没有或不投入专用测量设备的情况下,使用合适的有创呼吸机,选择呼吸机特定工作模式,可以对便携式肺功能仪进行测量,该方法对便携式肺功能仪的质量控制具有一定的参考意义和实用价值。Objective To provide an economical and effective method for quality control measurement of portable pulmonary function instrument, and to ensure the quality control of the measurement performance of portable pulmonary function instrument. Methods Referring to the experimental measurement method of national metrological calibration standard, and according to its technical requirements as the judgment basis of quality control measurement results, the invasive ventilator and standard respiratory simulator were used for experimental analysis and comparison. Results The method could be applied scientifically and practically for the quality control measurement of vital capacity, forced vital capacity, and maximum minute ventilation of portable pulmonary function instrument through theoretical analysis, experiment and result verification. Conclusion In the absence of dedicated measuring equipment, the portable pulmonary function instrument can be measured using appropriate invasive ventilator under the specific working mode. The method has certain reference significance and practical value for the quality control of the portable pulmonary function instrument.
