When a population or group of something is declining, and the amount that decreases is proportional to the size of the population, it's called exponential decay. In exponential decay, the total value decreases but the proportion that leaves remains constant over time.
A ventriculoperitoneal (VP) shunt is a medical device that relieves pressure on the brain caused by fluid accumulation. VP shunting is a surgical procedure that primarily treats a condition called hydrocephalus. This condition occurs when excess cerebrospinal fluid (CSF) collects in the brainâs ventricles. CSF cushions your brain and protects it from injury inside your skull.
A VP shunt needs to be put into place by means of a surgical procedure. If you have a VP shunt or if you are scheduled to have a VP shunt, then it would be beneficial for you to know some facts about VP shunts so you will know what to expect. What Is a VP Shunt? A VP shunt is a hollow tube with two openings, one on each end. One end of the tube is positioned underneath the skull, inside the ventricles. The other end of the tube extends down through the body, with the opening positioned in the space that surrounds the abdominal region, which is called the peritoneum.
