To provide a ventilation dynamic inspection system capable of accurately calculating lung compliance of a subject using a high frequency ventilation device for continuously supplying compressed air at highly frequent cycles.SOLUTION: A ventilation dynamic inspection system includes: an air supply part COMP1 for continuously supplying compressed air into the oral cavity of a subject U at highly frequent cycles; an oral cavity pressure measuring part 21 for measuring internal pressure of the oral cavity of the subject; an air flow rate measuring part 22 for measuring an air flow rate in the oral cavity of the subject U; and a calculation part 32 for calculating lung compliance of the subject U on the basis of an amount of change in the internal pressure of the oral cavity of the subject U measured by the oral cavity pressure measuring part 21 and a time integration amount of the air flow rate in the oral cavity of the subject U measured by the air flow rate measuring part 22 in the process of continuously supplying compressed air into the oral cavity of the subject at highly frequent cycles by the air supply part.SELECTED DRAWING: Figure 1 【課題】本発明は圧縮空気を高頻度のサイクルで連続的に送気する高頻度換気装置を用いて、被験者の肺コンプライアンスを精度良く算出することができる換気力学検査システムを提供することを目的とする。【解決手段】被験者Ｕの口腔内に対して圧縮空気を高頻度のサイクルで連続的に送気する送気部ＣＯＭＰ１と、被験者の口腔内圧を測定する口腔内圧測定部２１と、被験者Ｕの口腔内の気流量を測定する気流量測定部２２と、送気部により被験者の口腔内に対して圧縮空気を高頻度のサイクルで連続的に送気する過程において、口腔内圧測定部２１により測定された被験者Ｕの口腔内圧の変化量と、気流量測定部２２により測定された被験者Ｕの口腔内の気流量の時間積分量とに基づいて被験者Ｕの肺コンプライアンスを算出する算出部３２とを備える【選択図】図１
