NUR 290 Lecture Notes - Lecture 28: Cerebral Perfusion Pressure, Intracranial Pressure, Thoracic Diaphragm
Document Summary
It"s where pressure inside the skull has increased. Intracranial pressure is the pressure created by the cerebrospinal fluid and brain tissue/blood within the skull. It can be measured in the lateral ventricles. What is a normal icp: 5-15 mmhg (>20 mmhg needs treatment) The skull is very hard and is limited on how much it can expand when something inside the skull experiences a change that leads to increased pressure. Inside the skull are three structures that can alter intracranial pressure: brain, cerebrospinal fluid (csf, blood. To understand the patho of increased intracranial pressure, you must understand the. It deals with how icp is affected by csf, brain"s blood, and tissue and how these structures work to maintain cerebral perfusion pressure (cpp). In a nutshell, this hypothesis says that if the volume of one of these structures increases, the others must decrease their volume to help alleviate pressure.
