Csf production and drainage
CSF serves several purposes: 1. Buoyancy: The actual mass of the human brain is about 1400–1500 grams; however, the net weight of the brain suspended in CSF is equivalent to a mass of 25-50 grams. The brain therefore exists in neutral buoyancy, which allows the brain to maintain its density without being impaired by its own weight, which would cut off blood supply and kill neurons in the lower sections without CSF. WebOnce CSF flow is visualized after removal of catheter stylet, it can be transduced to obtain an opening intracranial pressure. It is then tunneled through the skin away from the point of entry through a separate incision, sutured securely in place, and then connected to an external drainage system. [ 10 ]
