Crystalloid osmotic pressure
WebAug 6, 2013 · Hypotonic solutions, including colloids (albumin) and crystalloids, may increase (the risk for) cerebral edema in traumatic brain injury, which seems determined in part by osmotic pressure, unless rapid excretion of hypotonic urine maintains plasma osmolality [ 71, 72 ]. WebMay 15, 2024 · Osmotic pressure relies on selective permeability in membranes. Take two of the major ions of the extracellular fluid: Na+ and Cl-, which can move rapidly between plasma and interstitial fluid spaces, thereby making them ineffective osmotic agents.

Most commercially available … Throughout the body, dissolved compounds have an osmotic pressure. Because large plasma proteins cannot easily cross through the capillary walls, their effect on the osmotic pressure of the capillary interiors will, to some extent, balance out the tendency for fluid to leak out of the capillaries. In other words, the oncotic pressure tends to pull fluid into the capillaries. In conditions where plasma proteins are reduced, e.g. from being lost in the urine (proteinuria), there will be a …
