翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Specific ventilation ： ウィキペディア英語版 Specific ventilation In respiratory physiology, specific ventilation is defined as the ratio of the volume of gas entering a region of the lung (ΔV) following an inspiration, divided by the end-expiratory volume (V0) of that same lung region: SV = It is a dimensionless quantity. For the whole human lung, given an indicative tidal volume of 0.6 L and a functional residual capacity of 2.5 L, average SV is of the order of 0.24. The distribution of specific ventilation within the lung can be inferred using Multiple Breath Washout (MBW) experiments 〔( Lewis et al ), S. M. Lewis, J. W. Evans, and A. A. Jalowayski. Continuous distributions of specific ventilation recovered from inert gas washout, Journal of Applied Physiology, 1978 vol. 44 no. 3 416-423〕 or imaging techniques such as Positron Emission Tomography (PET) using 13N, Magnetic Resonance Imaging (MRI) using either hyperpolarized gas (3He, 129Xe) or proton MRI (oxygen enhanced imaging). ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Specific ventilation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
