检查和测定肺水肿的方法颇多,现已日趋定量化。其中的一项定量方法是“肺血管外水量”(Pulmonary Extravascular Water Volume-PEWV或Extravascular Lung WaterEVLW)测定法。该法又分为在活体进行测定的“双指示物稀释法”(idQwl)及死后取出肺标本直接测定的“重量分析法”(Qwl)两
There are many ways to check and determine pulmonary edema, which has become increasingly quantitative. One of the quantitative methods is the Pulmonary Extravascular Water Volume-PEWV or Extravascular Lung Water EVLW assay. The law is subdivided into the “double indicator dilution” (idQwl) method for in vivo measurement and the “gravimetric method” (Qwl) for direct determination of lung specimens taken after death
