However the mechanism has not been clarified enough. On the other hand, the analysis of detailed mechanism in the case of artificial ventilation like HFOV (High Frequency Oscillatory Ventilation) is strongly required for the development of clinical treatments on patients with respiration disorder. In HFOV, it is considered that pendelluft becomes one of the important factors of gas transport and exchange because of high frequency ventilation in comparison with natural breathing. As increase of the frequency, the different time constants of lung units generate phase lag of ventilation in airways of lungs. The phase lag of ventilation causes to generate pendelluft. The time constant is determined by compliance and flow resistance of lung unit. In order to investigate the effect of the different time constants induced by the difference of flow resistance in a part of respiratory bronchiole of human lungs, the experimental study has been carried out by using multi-bifurcated micro channels as a model of bronchiole. The flow resistance in the model channels was produced by a stenosis. The velocity distributions of ventilation flows in the channels with and without the stenosis have been measured by using mu-PIV technique. The results obtained show the frequency effects on the flow pattern in the bronchiole model channels and the appearance of pendelluft.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"IOS PRESS"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13438875","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[著者版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Kim, J.-K."},{"subitem_text_value":"Kawahashi, Masaaki"},{"subitem_text_value":"Hirahara, Hiroyuki"},{"subitem_text_value":"Iwasaki, Y."}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002896"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科"},{"subitem_text_value":"埼玉大学大学院理工学研究科"},{"subitem_text_value":"埼玉大学大学院理工学研究科人間支援・生産科学部門"},{"subitem_text_value":"埼玉大学大学院理工学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"},{"subitem_text_value":"Mechanical Science Division, Graduate School of Science and Engineering, Saitama University"},{"subitem_text_value":"Mechanical Science Division, Graduate School of Science and Engineering, Saitama University"},{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2009"}]},"item_119_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kim, J.-K."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川橋, 正昭"},{"creatorName":"カワハシ, マサアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平原, 裕行"},{"creatorName":"ヒラハラ, ヒロユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Iwasaki, Y."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002896.pdf","filesize":[{"value":"568.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002896.pdf","url":"https://sucra.repo.nii.ac.jp/record/13438/files/A1002896.pdf"},"version_id":"bff08386-6274-40f2-83e7-93db6e19bc0d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ventilation","subitem_subject_scheme":"Other"},{"subitem_subject":"Respiratory bronchiole","subitem_subject_scheme":"Other"},{"subitem_subject":"HFOV","subitem_subject_scheme":"Other"},{"subitem_subject":"Micro channel","subitem_subject_scheme":"Other"},{"subitem_subject":"mu-PIV","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Experimental Analysis of Oscillatory Airflow in a Bronchiole Model with Stenosis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental Analysis of Oscillatory Airflow in a Bronchiole Model with Stenosis"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-06-29"},"publish_date":"2009-06-29","publish_status":"0","recid":"13438","relation_version_is_last":true,"title":["Experimental Analysis of Oscillatory Airflow in a Bronchiole Model with Stenosis"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-16T09:26:02.717278+00:00"}
