Pleural effusions can be due to excess fluid collection, transudative and exudative, or due to blockage of lymphatic drainage.

胸腔积是于体形成过快，分漏性胸水与渗性胸水，于淋巴引流阻塞，体吸收过缓。

Often, the biggest challenge is distinguishing between a transudative and exudative effusion, and the key difference is the amount of protein in the effusion - exudates have much more!

最大的挑战经常是辨别漏与渗，键的不同点是体里的蛋白质总量：渗中的含量更多！

Transudative fluid looks clear, exudative effusions are full of immune cells and therefore look cloudy, and lymphatic fluid is filled with fats and looks like milk.

漏透明清亮；渗里有许多炎性细胞，因此看起来混浊；淋巴里充满脂肪，所以看起来像牛奶。

An exudative pleural effusions is due to inflammation of the pulmonary capillaries which makes them much more leaky.

渗性胸腔积是因为肺毛细血管发炎，变得更易漏。
