    Running head: INTRACRANIAL REGULATION 1 Intracranial Regulation Name Institution Introduction Cerebrospinal fluid is a colorless body fluid that is found in the brain and spinal cord. It is produced by the choroid plexuses of the ventricle of the brain. It protects the cortex of the brain providing many mechanical protections. Also, it provides immunological to the brain in the skull. The brain produces about 500ml of cerebral spinal fluid which circulates and gets reabsorbed (Peterson et al, 2011). At any moment, only100-160ml is present. In a case of complete blockage of the flow of the cerebral spinal fluid, it leads to hydrocephalus and other malformations.…

  • Decompressive Craniectomy Case Study

    Decompressive Craniectomy and the Return of Functionality in Traumatic Brain Injury Patients with Increased Intracranial Pressure The brain and its surrounding protective bony layer provide for a unique situation with regards to traumatic brain injuries (TBI). Unlike other tissue in the body, which are free to expand outwards when inflammation or trauma occurs, the brain cannot. In the average adult, the cranial vault has the ability to accommodate for up to 1500mL of volume. When cerebral…

  • Arteriovenous Malformation Case Study

    pain and fifteen percent of people will experience poor speech, vision and difficulty with movement much like symptoms post stroke. Symptoms are more dependent on the location of the AVM in the brain. AVM’s are not specific to one part of the brain. The final diagnosis is detected with either a computerized tomography (CT) scan of the brain or magnetic resonance imaging (MRI). The cause of an AVM is unknown, they are not hereditary. Very rarely do AVM’s grow or change throughout a person’s…

  • Chronic Subdural Heatom A Case Study

    catheter as being tunneled under the scalp to prevent infection and dislodgement; it connected to an external drainage system that was lowered at least 20 cm below the patient’s head to create the needed pressure gradient for drainage. The physician ordered a CT scan which confirmed placement of the EVD. The drainage was monitored hourly for amount and characteristics; a focused neurologic exam was also performed at that time. The patient was kept in a supine position with head of bed flat; to…

  • Closed Head Injury Case Study

    Identify four late signs and symptoms of increased ICP. (2 points) 1) Decreasing level of consciousness leading to a comatose state (Hinkle & Cheever, 2014). 2) Decreased pulse rate, decreased respiratory rate, increased blood pressure and increased temperature (Hinkle & Cheever, 2014). 3) Cheyne-Stokes respirations (Hinkle & Cheever, 2014). 4) Loss of brain stem reflexes (Hinkle & Cheever, 2014). 8. List two medication classifications that the ICU nurse could use to control or reduce…

  • Niles Case Study

    of an act that a reasonably prudent person would or would not do. It is a form of conduct which is caused by the carelessness of the standard of care on reasonable members of the society; In the medical field it is consider malpractice. The person who shows negligence does not use their best judgment against possible risk. For example, in the case Dr. Haskins did not examine Kelly nor review his chart. He then advises Mr. Niles to take his son home. A red alert for negligence was also during…

  • Momentum Conservation Lab Analysis

    Now, the liquid flow governing equations are presented to determine the volume fraction of the liquid and its velocity. The capillary pressure at porous media is defined as the difference between pressure in the liquid and vapor phase. Mass conservation for liquid phase is as follow: (18) (∂(εsρ_l))/∂t+∇.(ρ_l u ⃗_l )=S_(g-l) Darcy law can be used for liquid momentum equation in porous media; therefore, momentum equation is reduced and can be expressed by: (19) u ⃗_l=-K_l/μ_l ∇p_l Also, the liquid…

  • Experiment Of The Marcet Boiler And Boyle's Law

    Abstract This lab report focuses on the two experiments on pressure systems conducted, the Marcet boiler and Boyle’s law. The aim of this lab is to investigate in pressure-temperature relationship, Boyle’s law, as well as steam quality. The results of this experiment support both relationship, as well as successfully providing a value for steam quality. For the Marcet boiler experiment, it was found that the higher the system pressure, the higher the saturated temperature. For the Boyle’s law…

  • Air Pressure In Football

    an intricate role in uniting families as well as communities in friendly banter, while taking one’s mind off the pressures that may engulf them on a daily basis. And even though this holds true, occasionally, during the season one will experience an upset or a scandal that will rock the nation. The world has bore witness to these types of upsets where the environment; the temperature, had a major effect on the outcome of the game and the teams who were the victors regardless. Whether an upset…
