Plasma Protein and Plasma Colloid Osmotic Pressure in Pathological Conditions With Special Reference to the Occurrence of Edema 1

Pulmonary Oedema

“…Now, the colloid osmotic pressure for pulmonary blood is, so far as we know, that of the blood in general, which is variously stated as 18.3 to 25 mm. Hg (Verney, 1926;Landis, 1930;Muntwyler et a!., 1933 ;Kerkhof, 1937). This means that tonditions favour retention of fluid within the pulmonary capillaries even when we take Into consideration the substmospheric (" negative ') intrapleural pressure fluctuating about a mean of 5 cm.…”

Osmotic Pressure Measurements of Serum and Ascitic Fluid in Patients With Cirrhosis of the Liver

“…This group consists mostly of young adult females who have been described elsewhere (28). Some (10).…”

“…However, when he added salt to the diet, the animals became edematous even at serum osmotic pressure levels near normal. The clinical counterpart of these experiments appears in the cases described in the literature (10) in which edema was absent at serum osmotic pressures below 200 mm.…”
