Darrow-Yannet Diagrams simplified

What are Darrow Yannet diagrams?
They are graphs that tell you the osmolarity and volume changes of body fluids.

X axis represents volume.
Y axis represents solute concentration.

Total body water = 2/3 ICF (Intracellular fluid) + 1/3 ECF  (Extracellular fluid)

All volume disturbances originate in the ECF compartment.
Changes in ICF are in response to changes in ECF.

How to make the graph in your head -
Step 1. Figure out what happens to the osmolarity and volume in the ECF compartment (ECF is the smaller compartment)
Step 2. Think how is ICF affected?

Let's review some examples to make sure we understand the concept!

What is the difference between prerenal failure & acute tubular necrosis?

What is prerenal failure?
Prerenal acute renal failure (ARF) occurs when a sudden reduction in blood flow to the kidney (renal hypoperfusion) causes a loss of kidney function.
In prerenal acute renal failure, there is nothing wrong with the kidney itself.

What is acute tubular necrosis?
Acute tubular necrosis is a kidney disorder involving damage to the tubule cells of the kidneys, which can lead to acute kidney failure.

Arteriovenous fistula - What happens to cardiac output and total peripheral resistance and why?

What is an AV fistula?
An arteriovenous fistula is an abnormal connection or passageway between an artery and a vein.

When an arteriovenous fistula is formed involving a major artery like the abdominal aorta, it can lead to a large decrease in peripheral resistance.
