| | Intracranial Pressure Monitoring |
 | | Intracranial pressure monitoring may be required for patients with a Glascow Coma Scale of 8 or less and is essential in patients in whom neurological assessment is unattainable (such as barbiturate therapy or neurological blockade). | | | Continuing monitoring provides data on intracranial pressure, cerebral perfusion pressure and responses to interventions and stimuli. | | | Intracranial pressure (ICP) monitoring provides continuous data regarding the pressure within the cranial vault. |

| | Ultimately it is the responsibility of treating surgeon relying on his experience and knowledge of the patient to decide the best for the patient. | | | There is a rise with cardiac systole (due to distention of intracranial arteriolar tree which follows) and a slower change in pressure with respiration, falling with each inspiration and rising with expiration. | | | Monitoring is the only means by which therapy can be selectively employed and the effectiveness of therapy can be accurately studied. |

| | During this period close observation should be done to monitor patient activity at the time of change in intracranial pressure. | | | In a simplified statement cerebral perfusion pressure is the difference between the systemic blood pressure and the intracranial pressure. | | | The cerebral blood flow is dependent on the intracranial pressure. |

| | This is a procedure in which a needle is inserted through the skin of the lower back and into the spinal column. | | | Sometimes, special instruments are placed through the skin and into the skull to measure the intracranial pressure. | | | An increased pressure in the skull can put too much pressure on the brain and decrease blood flow to the brain. |

| | Intracranial Pressure Monitoring |
| | A common complication of many serious neurologic conditions is an elevation of the pressure within the skull, the intracranial pressure or ICP. | | | Low blood pressure (hypotension) can cause inadequate blood flow to the brain, especially if intracranial pressure is already elevated. | | | Intraventricular catheters also are unique in that they can simultaneously monitor and treat increased intracranial pressure. |

| | The change in intracranial blood volume that occurs naturally during each cardiac cycle is calculated from the difference between blood and cerebrospinal fluid flows into and out of the brain. | | | The invasive tests are done by inserting a catheter into the brain or a needle into the lumbar spine, both of which carry a risk of further injury. | | | In patients with head injuries, for example, studies have shown that if the pressure is monitored and managed, mortality rates drop from 50 percent to 30 percent. |
