Intracranial pressure (ICP) is derived from cerebral blood and cerebrospinal fluid (CSF) circulatory dynamics and can be affected in the course of many diseases of the central nervous system. Monitoring of ICP requires an invasive transducer, although some attempts have been made to measure it non-invasively. Because of its dynamic nature, instant CSF pressure measurement using the height of a ...

Raised intracranial pressure (ICP) and low cerebral blood flow (CBF) are associated with ischaemia and poor outcome after brain injury. Therefore, many management protocols target these parameters. This overview summarizes the technical aspects of ICP and CBF monitoring, and their role in the clinical management of brain-injured patients. Furthermore, some applications of these methods in curre...

BACKGROUND AND PURPOSE Patients with large middle cerebral artery infarction and elevated intracranial pressure (ICP) who are undergoing invasive intensive care therapy require technical monitoring. However, the effectiveness of the current gold standard, measurement of ICP, is limited. Furthermore, the effects of what is considered to be standard antiedema medical treatment are not fully under...

Introduction: In the US, about 60,000 victims of traumatic brain injury (TBI) survive long enough to reach the emergency department (ED). Approximately half of these (30,000) will require careful monitoring of intracranial hypertension [1]. Besides the intracranial pressure (ICP) measurements of TBI patients in the ED, continuous ICP measurements are sometimes essential in terms of managing a p...

Although a variety of techniques are available to measure nanoparticles, single particle ICP-MS (SP-ICP-MS) has become increasingly important due to its speed and ability to measure environmentally relevant low nanoparticle concentrations, surpassing the limitations of light-based technologies.6-7 Monitoring Cerium Dioxide and Zinc Oxide Nanoparticles through Drinking Water Treatments using Sin...

Acute brain injury states (e.g. head injury, subarachnoid haemorrhage) show clear inverse relationships of ICP vs compliance, with ICP instability at times of lower compliance states. Variance in compliance values is large in hydrocephalus where ICP is relatively lower and compliance higher. Nonetheless, early experience shows that compliance data influence decisions on CSF diversion treatments...

Continuous monitoring of brainstem auditory evoked potentials (BAEPs) was carried out in 57 comatose patients for periods ranging from 5 hours to 13 days. In 53 cases intracranial pressure (ICP) was also simultaneously monitored. The study of relative changes of evoked potentials over time proved more relevant to prognosis than the mere consideration of "statistical normality" of waveforms; thu...

Mortality is higher in patients with traumatic brain injury (TBI) resuscitated with albumin compared with saline, but the mechanism for increased mortality is unknown. In patients from the Saline vs. Albumin Fluid Evaluation (SAFE) study with TBI who underwent intracranial pressure (ICP) monitoring, interventional data were collected from randomization to day 14 to determine changes in ICP (pri...

Introduction: Standard monitoring of severe traumatic brain injury patients (TBI) by intracranial pressure (ICP) and cerebral perfusion pressure (CPP) monitoring fails to recognize episodes of cerebral oxygen desaturation. We found and characterized frequent episodes of desaturation of jugular venous oxygen (SjO2) in the face of normal ICP and CPP. Methods: Fifty six patients with severe TBI ha...
