The cause of the fluid buildup must also be treated: Updated by: Denis Hadjiliadis, MD, MHS, Paul F.

Let me just change my colors so we can see that we're talking about fluid.It's going to cause the fluid to actually shift out in between my endothelial cells outside of the actual vessels, so i'm going to have fluid shift out.Our transudate and our exudate is going to help differentiate how these things happened. So something that's changed in pressure in the vessels, or something that has actually caused inflammation in the vessels, so that's how we differentiate those two. What we're looking at here is an image of a normal vessel.Now normally when we're talking about an exudate it's something that was inflammatory. Whereas something that was transudate is something that's changed the hydrostatic...oops, I think I spelled that wrong. You'll see that this is our vessel wall, right?Pleural effusion is an abnormal, excessive collection of this fluid.
Chest CT scan or a chest x-ray may be enough for your provider to decide on treatment.Now you'll see that the endothelial cells in the vessel, this hasn't changed.My vessel looks the same, and the endothelial cells are still sitting next to each other.Another way we can have a transudate leak is by let's say congestive heart failure. Now let's say that this person had left sided heart failure, so we've got heart failure on the left side. We know that the left side of the heart will back up to our lungs. Now if the pressure is increased that means that it's backing up towards our lungs, and the vessels in our lungs, it's going to cause an increase in pressure.That would be the increase in our hydrostatic pressure that causes transudate, and as a result the same idea here, that fluid that we have going on here, that fluid is going to be forced out in-between the endothelial cells because the pressure is so high.
The real difference between the two is how that fluid came about to be in that space.
