翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Negative room pressure ： ウィキペディア英語版 Negative room pressure Negative room pressure is an isolation technique used in hospitals and medical centres to prevent cross-contaminations from room to room.〔(Negative Room Pressure to Prevent Cross-Contamination ), Clean Air Solutions, Camil Farr, Retrieved 2010-03-10.〕〔(Isolation Rooms & Pressurization Control ), Penn State Department of Architectural Engineering, © 2008 The Pennsylvania State University. Retrieved 2010-03-10.〕 It includes a ventilation system that generates negative pressure to allow air to flow into the isolation room but not escape from the room, as air will naturally flow from areas with higher pressure to areas with lower pressure, thereby preventing contaminated air from escaping the room. This technique is used to isolate patients with airborne contagious diseases such as tuberculosis, measles, or chickenpox.〔(Negative Pressure Isolation Rooms & Tuberculosis (TB) Isolation Rooms ), AirMont Inc. Retrieved 2010-03-10.〕〔P. N. Hoffman, a, M. J. Weinbrenb and S. A. Stuartc. (A practical lesson in negative-pressure isolation ventilation ). Journal of Hospital Infection. Volume 57, Issue 4, August 2004, Pages 345-346.〕 ==Mechanism== Negative pressure is generated and maintained by a ventilation system that removes more exhaust air from the room than air is allowed into the room. Air is allowed into the room through a gap under the door (typically about one half-inch high). Except for this gap, the room should be as airtight as possible, allowing no air in through cracks and gaps, such as those around windows, light fixtures and electrical outlets. Leakage from these sources can compromise or eliminate room negative pressure.〔 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「Negative room pressure」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.
