目前,无论外部检测法,还是稀释法都不能鉴别心脏性、体内水份过多(包括肾功能衰竭)和毛细血管渗透性肺水肿。旨在检出肺毛细血管渗透性增加和测定肺水肿液体内蛋白含量的新技术。虽然有助于肺水肿病因的鉴别。但这些方法在日常常规工作中不易应用。 Currently, neither external nor the dilution method discriminates between cardiac, excess body fluid (including renal failure) and capillary permeability pulmonary edema. A new technique designed to detect increased pulmonary capillary permeability and to determine the protein content of pulmonary edema fluids. Although it helps to identify the etiology of pulmonary edema. However, these methods are not easy to apply in routine work.
