自19世纪60年代以来，医疗保健建筑师和工程师一直强调通风的必要性。本文的目的是总结卫生保健通风实践背后许多不断变化的概念。本文解释了随着时间的推移而演变和发展的一些概念。它特别关注与医疗空间相关的概念。它将这些发展与其他非住宅建筑的通风率历史进行了比较。涵盖的主题包括:从瘴气到细菌理论的发展，以及瘴气对建筑的影响，2 ach作为室外空气通风标准的起源，空气中细菌的发现，非居住室外空气率的历史发展和医疗室外空气率的比较进展，美国医疗法规的出现和发展。 美国，使用过滤空气或室外空气作为败血症控制技术，通风改革和20世纪70年代美国能源危机带来的压力，结核病和建筑粉尘控制，清洁空气技术的历史进步和与医疗空间的相关性，非住宅通风的现代进步，以及关于空气质量与感染控制相关性的文献共识。引文:2015年年度会议，佐治亚州亚特兰大，2015年交易，第121卷。2.

Health care architects and engineers have stressed the need for ventilation since the 1860s. The purpose of this paper is to summarize the many changing concepts behind health care ventilation practices. This paper explains a number of concepts that have evolved and developed over time. It looks specifically at concepts considered relevant to health care spaces. It compares those developments to the history of ventilation rates used in other nonresidential buildings. Topics covered include: Progression from miasma to germ theory and the architectural influence of miasma, the origin of 2 ach as an outside air ventilation standard, discovery of airborne germs, historical progression of nonresidential outdoor air rates and comparative progression of health care outdoor air rates, the advent and progression of health care codes in the U.S., use of filtered or outdoor air as a sepsis control technique, ventilation reforms and pressures resulting from the U.S. energy crisis of the 1970s, tuberculosis and construction dust controls, historical progression of clean air technology and relevance to health care spaces, modern advancements in nonresidential ventilation, and the consensus of literature on the relevance of air quality to infection control.
