Plasma Volume Expansion via Oncotic Pressure (N/A)

Plasma volume expansion via oncotic pressure is the physiological process by which plasma proteins, primarily albumin, create a colloid osmotic pressure that draws water into the vascular compartment. This mechanism is crucial for maintaining blood volume, preventing edema, and ensuring circulatory stability. It is frequently manipulated therapeutically using intravenous colloids to treat hypovolemia and related conditions.
