目的比较呼吸感应体积描记技术(RIP)的6种校准方法在人体不同呼吸状态下的适用性。方法用平静呼吸的6种校准参数测量平静和规范用力的每次呼吸通气量,用规范用力呼吸的6种校准参数测量规范用力的每次呼吸通气量,对比分析RIP系统与呼吸速度描记仪所测量的通气量值。结果 6种校准方法中,诊断性定性校准技术(QDC)适用于在平静呼吸下校准测量平静呼吸每次呼吸通气量值以及在规范用力呼吸下校准测量规范用力呼吸每次呼吸通气量值,LSQ改进算法(ILSQ)适用于在平静呼吸下校准测量规范用力呼吸每次呼吸通气量值。结论 RIP系统在平静呼吸状态下校准测量规范用力呼吸方式下每次呼吸通气量值方法可行。
Abstract：Objective To compare the applicability of 6 calibration methods for respiratory volumes accuracy under different breathing conditions in respiratory inductive plethysmography (RIP).Methods Ventilation of each standardized forced breath (SFB) and natural breath(NB) employing parameters were measured with 6 methods under NB, and ventilation of each SFB employing parameters from 6 calibrated methods under SFB were evaluated.Ventilation measured from RIP system and pneumotachometer (PTM) were compared and analyzed.Results Qualitative diagnostic calibration(QDC) was appropriate for the two conditions of measuring ventilation of NB by calibrated parameter from the NB pattern and evaluating ventilation of SFB by calibrated parameter from the SFB pattern. Improved LSQ algorithm(ILSQ) was suitable for measuring ventilation of SFB by calibrated parameter from the NB pattern. Conclusion RIP system calibrated under NB is practical to measure ventilation of each breath under SFB.
