Non-Invasive Intracranial Pressure Method and Monitor
… of the eye and the coupled brain. Changes in the intracranial pressure via the vibrational response induce changes in the intraocular pressure via the vibrational principle. Further, the model supports the observation that vibration delivered to the eye can be perceived as sound, if of sufficient …

The Measurement and Interpretation of Intracranial Pressure
The intracranial pressure (ICP) is the most commonly monitored brain parameter in neurocritical care. Its rise, which may be benign, acute or chronic, is a common yet serious problem. ICP can rise because of a number of critical medical conditions such as hydrocephalus, traumatic brain injury, …

Frequency domain model-based intracranial pressure estimation
Elevation of intracranial pressure (ICP), the pressure of the fluid surrounding the brain, can require urgent medical attention. Current methods for determining ICP are invasive, require neurosurgical expertise, and can lead to infection. ICP measurement is therefore limited to the sickest …

A spectral approach for noninvasive estimation of intracranial pressure
Intracranial pressure (ICP) is an important clinical indicator of neurological injury and is used in the diagnosis, treatment and monitoring of several neurological pathologies. Current measurement modalities of ICP are highly invasive, largely limiting the measurement to critically ill patients. …

NON-INVASIVE MONITORING OF INTRACRANIAL PRESSURE USING TRANSCRANIAL DOPPLER ULTRASONOGRAPHY
Intracranial pressure (ICP) is an important monitoring modality in the clinical management of several neurological diseases carrying the risk of fatal intracranial hypertension. However, this parameter is not always considered due to its invasive assessment. In this scenario, a non-invasive …

An embedded device for real-time noninvasive intracranial pressure estimation
Monitoring of intracranial pressure (ICP) is key in many neurological conditions for diagnosis and guiding therapy. Current monitoring methods are highly invasive, limiting their use to the most critically ill patients. Based on a previously developed approach to noninvasive ICP estimation from …

Effects of Elevated Intracranial Pressure on a Cerebral Vein Model
… The effects of occluded cerebral venous flow on intracranial pressure (ICP) have not been considered in a model for HBI as opposed to the context of stroke and neonatal hypoxic-ischemic encephalopathy. In this project, the effects of elevated ICP on the hemodynamics and structural dynamics of a …

Intracranial pressure monitoring as an early predictor of third ventriculostomy outcome
Includes abstract (p. [43].) Includes bibliographical references.

A pseudo-Bayesian model-based approach for noninvasive intracranial pressure estimation
A noninvasive intracranial pressure (ICP) estimation method is proposed that incorporates model-based estimation within a probabilistic framework. A first-order subject-specific model of the cerebral vasculature relates arterial blood pressure with cerebral blood flow velocity. The model is solved …

A spectral approach to noninvasive model-based estimation of intracranial pressure
Intracranial pressure (ICP) is the hydrostatic pressure of the cerebrospinal fluid. Ideally, ICP should be monitored in many neuropathological conditions, as elevated ICP is correlated with poor neurocognitive outcomes after injuries to the brain. Measuring ICP requires the surgical placement of a …

The Effect of Oral Care on Intracranial Pressure in Critically Ill Adults
… is to prevent or minimize episodes of increased intracranial pressure (ICP). Elevations in ICP in response to nursing interventions have been acknowledged since the 1960’s when ICP monitoring was first introduced in the clinical setting. Until recently few studies have specifically examined the …

What Nursing Personnel Know About Identifying the Signs of Increased Intracranial Pressure
… know about identifying signs of increased intracranial pressure and what understanding they have regarding the importance of prompt reporting of these signs.</p> <p>A statement was prepared describing what the registered nurse, the license vocational nurse and the nursing assistant should …

Paediatric traumatic Brain Injury: The relationship between Intracranial Pressure and Brain Oxygenation
Introduction: Intracranial pressure (ICP) monitoring is a cornerstone of care for patients with severe traumatic brain injury (TBI). The primary goal of ICP treatment is to preserve brain oxygenation, and since brain oxygenation is usually not measured, the control of ICP is used as a surrogate …

A Study of Measuring Intracranial Pressure Using a Non-Invasive Piezoelectric Sensor
… When cerebral edema occurs, a rise in intracranial pressure (ICP) becomes prevalent and may cause a serious threat. Without immediate treatment, increased intracranial pressure can prevent blood from flowing to the brain and depriving it of necessary oxygen it needs to function. A …

Relationships of intracranial pressure, cerebrospinal fluid space and head circumference in young children
… evaluate and analyze the relationships between intracranial pressure (ICP), cerebrospinal fluid space (CSF) and head circumference (HC). The medical records at single institution from 2007 through 2011 inclusive were reviewed to identify 780 patients under 6-year-old who underwent a lumbar …

Modeling and estimation for non-invasive monitoring of intracranial pressure and cerebrovascular autoregulation
… for developing or exacerbating brain injury. Intracranial pressure (ICP), which is the pressure of the cerebrospinal fluid, is a vitally important variable to monitor in a wide spectrum of medical conditions involving the brain, such as traumatic brain injury, stroke, hydrocephalus, or brain …

Investigating the effects of acute intracranial pressure and brain oxygenation on neuropsychological outcomes 12 months after severe pediatric traumatic brain injury
… between acute stage physiological changes in intracranial pressure (ICP) and brain tissue oxygenation (PbtO2) and neuropsychological outcomes one year after pTBI. Results of the study indicated that children who sustained TBI performed significantly poorer than healthy, matched controls on …

Ultrasound as a non-invasive diagnostic tool in paediatric neurosurgery : relationship between the optic nerve sheath diameter (ONSD) and intracranial pressure (ICP)
Background: Assessment of intracranial pressure (ICP) is an essential aspect in the management of most neurosurgical conditions in children. While invasive ICP monitoring is considered the criterion standard, the need for a reliable, non-invasive, easy-to-use and accurate method to detect and …
