The thorax accumulates production of the liquid and _ general knowledge of the manifestation
The circulation mechanism of water of chest:
Chest water because the intersection of pressure and gradient enter the pleura from the intersection of wall and layer and dirty layers of systemic circulation blood vessel of pleura through the pleura with seepage nature, then absorb (function on the water circulation of chest of the dirty layer of pleuras under normal situation less by the lymphatic vessel through the lymphatic vessel capillary of one layer of pleuras of wall) . Wall layers of the intersection of fluid and quiet the intersection of water pressure and about 30cmH2O pleuras of pleura pigeonhole and invite - 5cmH2O, its quiet water pressure of fluid equals 30- (- 5) =35; The one opposite to quiet water pressure of fluid is that the colloid of blood plasma permeates, presses gradient, the colloid of blood plasma permeates, presses about 34cmH2O, water of chest contains a few albumens, its colloid permeates and presses about 5cmH2O, it is 34-5 that the colloidal infiltration that is produced presses gradient =29; It is 35-29 that the quiet water pressure of fluid and colloid permeate the difference pressed =6.
The thorax accumulates the liquid:
The pleura is a negative pressure and one of cracks of locating between lung and wall of the chest, there is thin liquid that plays a lubricated role in the pleura in breathing sports under the normal situation, in dynamic equilibrium state liquid this, any can make the intersection of pleura and of inner liquid form too fast or absorb slow factor can produce thorax accumulate liquid (the intersection of chest and ink) .
The mechanism that the thorax accumulates the liquid and produces:
1,Quiet water pressure increases in the pleura capillary; If congestive and in heart failure, draw back narrow pericarditis, blood capacity increasing, superior vena cava or umbilicus vein is obstructed.
2,The colloid permeates and presses to reduce in the pleura capillary; Such as low albumen blood disease, liver cirrhosis, nephropathy and syndrome, acute glomerulus nephritis, mucus edema.
3,Penetrating increase of pleura; Such as pleura inflammation (pulmonary tuberculosis, pneumonia) , desmosis (systemic lupus erythematosus, rheumatoid arthritis) , the pleura tumour (malignant tumour is shifted, a cover tumour) , lung infarction, diaphragm make inflammation (diaphragm plays the abscess, liver abscess, acute pancreatitis
4,One storey of pleuras is lymphocytic to guide the obstacle in the wall; Block by cancer lymphatic vessel, development lymphatic vessel guided unusually.
5,Damage. If main aneurysm break and esophagus break and the intersection of chest and conduit break, produce hemothorax, strong the intersection of chest and the intersection of chyle and chest.
