The thorax accumulates _'s general knowledge of pathogenesis of liquid
The thorax accumulates the liquid and mechanism absorbed
Healthy people's pleura, for negative pressure (- 5cmH2O, 1cmH2O=98Pa equally while breathing) ,Include protein in the liquid of chest, there is colloid that permeates and presses ( 8cmH2O) . The gathering of liquid of chest and the dissipation, also with permeating pressing, quiet water pressure and having close relations in the pleura capillary. One storey of pleuras of wall is by the blood supply of the systemic circulation, quiet water pressure high ( 30cmH2O) of the capillary ; The dirty layer of pleuras is circulated the blood supply by the lung, intravenous to force down ( 11cmH2O) . Systemic circulation and circulation blood membrane of lung are absorbed at the equal speed
Calculate according to animal's experiment, the pleura of every day of human body can have 0.5- 1L liquid to pass. Protein in the liquid of chest mainly enters the chest conduit via the lymphatic vessel.
Pleura inflammation can make the tube wall penetrating and increase, more proteins enter the pleura, make the liquid of chest permeate and press to increase. Tumour can be oppressed, blocked lymphocytically and guided, cause in the liquid of chest protein accumulates, cause the thorax to accumulate the liquid. Portal vein liver cirrhosis often has low albumen blood diseases, the colloid of blood plasma permeates, presses, reduces, can produce and leak the liquid, can cause the thorax to accumulate the liquid through inborn defect of the skin of diaphragm or by the lymphatic vessel when there is ascitesing. Allergy disease, oneself immune disease, cardiovascular vessel,etc., increasing may produce the thorax and accumulate the liquid.
