WebThe Shunt equation (also known as the Berggren equation) quantifies the extent to which venous blood bypasses oxygenation in the capillaries of the lung. “Shunt” and “ dead space “ are terms used to describe conditions where either blood flow or ventilation do not interact with each other in the lung, as they should for efficient gas exchange to take place. WebThe shunt system is generally composed of a valve that regulates flow of cerebrospinal fluid (CSF), a proximal catheter that drains it from the brain or spinal column to the valve and a distal catheter that drains the CSF from the valve into the abdominal cavity or heart generally. The shunt patency is a study to determine if cerebrospinal ...
