The watershed program offers technical assistance to watershed groups, municipalities, and individual citizens. A watershed is a geographic area of land across which water, and the sediments and dissolved materials it contains, flow on their way to a single common outlet -- a stream, lake or river.
What is Lumboperitoneal Shunt? Lumboperitoneal (LP) shunt is an artificial connection created by neurosurgeons which allows excess of cerebrospinal fluid to leave the subarachnoid space and enter the peritoneum. From there, the fluid is easily absorbed and eliminated via the circulatory system and the kidneys.
How It Works. A shunt usually consists of two catheters and a one-way valve. The valve regulates the amount, flow direction, and pressure of cerebrospinal fluid out of the brainâs ventricles. As the pressure of cerebrospinal fluid inside the brain increases, the one-way valve opens and the excessive fluid drains to the downstream cavity.
