Sudden increases in intracranial pressure (ICP) are extremely serious and can be life-threatening. Up to the present moment, effective methods have been studied to return the ICP to normal levels after a rapid increase has occurred. This study analyzes different characteristics of the ICP signal just prior to the occurrence of an increase, and compares it with the characteristics of the signal ...

The purpose of this paper is to study the influence of face expressions on the performance of a 3D face recognition algorithm. Three facial surface matching based algorithms, namely ICP, Localized ICP (LICP) and Region-based ICP (R-ICP), are benchmarked on several sets of data : the two first sets with neutral faces and the last with expressive ones. Results show that the R-ICP algorithm provid...

BACKGROUND The diagnostic gold standard for diagnosing chronic exertional compartment syndrome (CECS) is a dynamic intracompartmental pressure (ICP) measurement of the muscle. The potential role of a repeat ICP (re-ICP) measurement in patients with persistent lower leg symptoms after surgical decompression or with ongoing symptoms after an earlier normal ICP is unknown. PURPOSE To study wheth...

The effect of vecuronium on intracranial pressure (ICP) was investigated in six cats with normal and increased ICP. Cats were anaesthetized with pentobarbitone 33 mg kg-1 i.p. and acepromazine 0.6 mg kg-1 i.p., the trachea was intubated, and the lungs ventilated with nitrous oxide in oxygen. Mean arterial pressure (MAP), heart rate (HR), twitch response and ICP were recorded continuously. After...

Invasive devices are recommended for the early detection of raised intracranial pressure (ICP) after severe traumatic brain injury. Owing to contraindication or local issues, however, invasive ICP monitoring is not always possible. Moreover, a significant proportion of moderate traumatic brain injury patients (managed without invasive ICP) will develop raised ICP. Reliable noninvasive ICP techn...

Objective: This article describes a novel method for processing continuous intracranial pressure (ICP) signals with lifting wavelet transformation and discrimination rules for ICP waveform morphology. Methods: First, lifting wavelet was applied to detect the extreme points of ICP waveform preliminarily; then, the extreme points that were undetected or falsely detected are determined by using th...

PURPOSE Because a lowered intracranial pressure (ICP) is a possible mechanism of optic neuropathy, we wished to study the CSF dynamics in the optic nerve chamber by recording possible changes in the optic nerve subarachnoid space pressure (ONSP) and the impact on it when acutely lowering ICP. METHODS In eight normal dogs pressure probes were implanted in the left brain ventricle, lumbar ciste...

BACKGROUND In brain-injured patients intracranial pressure (ICP) is monitored invasively by a ventricular or intraparenchymal transducer. The procedure requires specific expertise and exposes the patient to complications such as malposition, hemorrhage or infection. As inner-ear fluid compartments are connected to the cerebrospinal fluid space, ICP changes elicit subtle changes in the physiolog...

OBJECTIVES To determine the alterations in intracranial pressure (ICP) during U. S. Air Force Critical Care Air Transport Team transport of critically injured warriors with ICP monitoring by intraventricular catheter (IVC). METHODS Patients with an IVC following traumatic brain injury requiring aeromedical evacuation from Bagram to Landstuhl Regional Medical Center were studied A data logger ...

Increased intracranial pressure (ICP) is a serious complication of a variety of neurologic injuries and is a major challenge in intensive care units. The most common causes of increased ICP are: traumatic brain injury (TBI), stroke, neoplasms, hydrocephalus, hepatic encephalopathy, CNS venous return impairment, encephalitis, and abscesses. Prompt diagnosis and intensive monitoring and therapy o...
