Oncotic pressure (colloid osmotic pressure) and albumin (hypoalbuminemia) explained in fluid movement: Fluid and electrolytes #shorts review.

Oncotic pressure is the pulling effect on water, and it is highly dependent on a protein called albumin, which is a colloid.

Albumin hangs out in high amounts within the capillaries, and it is so big that it cannot escape the capillary walls.

Because there is a high concentration of albumin in there, it creates osmotic pressure, which is going to pull water into the intravascular space (plasma).

However, if the patient has a low albumin level, water is going to escape from the intravascular space and go into the interstitial space, causing swelling in the tissues.

What conditions can cause a low albumin level? Liver failure can do this because the liver makes albumin. Kidney failure or severe burns can also cause this.
