Abstract

The basics of pleural liquid dynamics are summarized. The normal pleural cavity contains a small amount of pleural liquid (0.1-0.3 ml/kg). Its protein concentration is about 1.0 g/dl and its pH is 7.6. The normal flow of pleural liquid is gravity dependent, and pleural liquid flows from the costal to the mediastinal region. In experimental hydrothorax, the pleural liquid was removed mainly via lymphatics. The turnover of the pleural liquid is rapid, and it depends on the area of contact between pleural liquid and pleural and on the blood flow to the pleura.

摘要

总结了胸腔液体动力学的基础知识。正常胸腔内含有少量胸腔积液（0.1 - 0.3 ml/kg）。其蛋白质浓度约为1.0 g/dl，pH值为7.6。正常胸腔积液的流动依赖于重力，胸腔积液从肋部流向纵隔区域。在实验性胸腔积液中，胸腔积液主要通过淋巴管清除。胸腔积液的更新很快，它取决于胸腔积液与胸膜之间的接触面积以及胸膜的血流量。
