弥散功能是呼吸生理的一个重要环节。各种心肺疾患凡能引起气体交換面积减少或肺泡毛細管膜增厚者,均能发生弥散功能障碍。弥散功能測驗,目前以一氧化碳弥散量測定为最普遍,其中分为进气法和稳定状态法两种。
Diffuse function is an important part of respiratory physiology. A variety of cardiopulmonary diseases can cause gas exchange area reduction or alveolar capillary membrane thickening who can have diffuse dysfunction. Diffuse functional test, the current dispersion of carbon monoxide measured as the most common, which is divided into two methods of intake method and the steady state.
