Osmotic pressure of the serum proteins.

The osmotic pressure of the serum proteins (colloid osmotic pressure [COP] or "oncotic" pressure) is only one of the four Starling forces (plus the capillary permeability coefficient) which affect the net filtration of fluid from the capillaries. The COP will vary with the concentration of total serum proteins, but more so with the specific pattern or composition of the protein components, espe...

Stability of Colloid Osmotic Pressure of Serum Protein By

The work of earlier investigators, Govaerts (1), Barath (2), Cope (3), Peters et al. (4) and Kylin (5) has given the impression that the colloid osmotic pressure is not only lowered with decrease in serum protein but its specific pressure (pressure per unit of protein) is also diminished. The lowering of specific pressure has usually been related to a greater decrease in the albumin fraction of...

Measurements of serum colloid osmotic pressure are of limited usefulness.

We examined the usefulness of serum colloid osmotic pressure measurement in patients with chronic rather than acutely occurring low serum protein concentrations. We used two oncometers, the IL 186 Weil Oncometer and the Wescor Model 4100; results from the two instruments were interchangeable. Values for the colloid osmotic pressure were compared with those for serum total protein (r = 0.783) an...
