Document Summary
Nursing care for traumatic brain injury: define intracranial pressure (icp). Icp is the volume & pressure of brain tissue, (80%) blood, (10%) and csf (10%) are usually in a state of equilibrium and produce the intracranial pressure (icp) Icp is usually measured in the lateral ventricles; 10-20 mm hg. Clinical manifestation: change in loc restlessness confusion increasing drowsiness. Patient became stuporous, reacting only to loud auditory or painful stimuli. Abnormal motor responses in the form of decortication, decerebration, or flaccidity. Occlusion of catheter by brain tissue or blood. Blockage of screw by clot or brain tissue, which leads to a loss of pressure tracing and a. A fine bone catheter is inserted into the lateral ventricle, usually in the nondominant hemisphere of the brain. The catheter is connected by a fluid-filled system to a transducer, which records the pressure in the form of an electrical impulse. The catheter allows cfs to drain, particularly during acute rises in pressure.
