Colloid-interface interactions initiate osmotic flow dynamics

Dynamics of osmotic fluid flow

The classical thermodynamic treatment of osmotic pressure is quite sufficient to describe equilibrium situations and compute most quantities of interest without reference to any molecular model (see, for example, Finkelstein, 1987). However, one's intuition is always aided by molecular models, and a microscopic picture can be quite useful when thinking about osmotic flow in unfamiliar situation...

Plasma colloid osmotic pressure in healthy infants

BACKGROUND The plasma colloid osmotic pressure (COP) plays a major role in transcapillary fluid balance. There is no information on plasma COP of healthy infants beyond the first post-natal week. The normal COP in healthy adult subjects (25 mmHg) is currently also applied as a reference value for healthy infants. This study was designed to test whether plasma COP values in healthy infants are t...

Colloid Osmotic Pressures of Serum Proteins

The albumin component is, by reason of size and net charge and concentration, chiefly responsible for plasmas osmotic activity ( 1) .2 The validity of Starling's hypothesis in the dynamics of water balance in conditions associated with hypoproteinemia has been the subject of considerable recent discussion. The basic experimental problems involved have been considered by some of us in other publ...

The Relationship of the Colloid Osmotic-

The relationship of serum colloid osmotic pressure (COP) and pulmonary artery wedge pressure (PAWP) to pulmonary edema and mortality was investigated in 76 critically ill patients. Forty patients suffered from circulatory shock and 36 dId not. The COP-PAWP gradient and radiographic evidence of pulmonary edema were measured at the time of diagnosis. The COPPAWP gradient was markedly decreased in...
