Intracranial pressure (ICP) monitoring and management have substantially improved the outcome of patients with traumatic brain injury (TBI). However, rapid elevations in ICP remain a significant problem as they may lead to secondary brain injury and worse outcome due to cerebral ischemia. Current therapy is targeted towards treating rapid ICP elevations after they occur. Ideally, anticipatory t...

We present a clustering algorithm based on Dynamic Time Warping (DTW) to automatically classify intracranial pressure (ICP) beats based on their morphology. The algorithm detects, classifies and labels each beat as a low–pressure or high–pressure beat based on morphology. The trend is removed during prepocessing to ensure the classifications are independent of the mean ICP. An ICP beat detectio...

In this paper, the correlation between intracranial pressure (ICP) and external vibration responses of the head was studied using finite element modeling. A two-dimensional finite element model of the head was constructed from magnetic resonance imaging (MRI) slice. The finite element model includes the skull, the cerebrospinal fluid (CSF) and the brain tissue. Material properties of the three ...

purpose: to evaluated the correlation between intracranial pressure (icp) and intraocular pressure (iop). methods: this interventional case series included 90 patients undergoing lumbar puncture (lp) for neurologist evaluation. iop was measured before and 1 hour after the lp by using goldmann tono-meter. patients were compared into two groups: patients with normal icp (<20 cmh2o) and patients w...

main goal in the management of patients with severe traumatic brain injury (tbi) is control of intracranial pressure (icp). decompressive craniectomy is an accepted technique for control of refractory intracranial hypertension in patients with severe tbi. because of high complication rate after decompressive craniectomy, new techniques such as basal cisternostomy have developed. we herein repor...

Physiology and pathophysiology The management of a patient who has sustained a severe cerebral insult requires an understanding of the volume pressure relationship of the intracranial contents: cerebrospinal fluid (CSF), intravascular blood, and brain tissue. Intracranial pressure (ICP) is the pressure relative to atmospheric pressure within the ventriculo-subarachnoid space. Pressures are give...

Slow waves in intracranial pressure (ICP) and related signals seems of interest to evaluate the dynamic autoregulation, i.e. by comparison of the frequency links between an intracranial signal, e.g. ICP, cerebral blood velocity (CBV), and arterial blood pressure (ABP). To clarify the links, we compared two frequency methods based on coherence function to estimate the influence of ICP, ABP and C...

BACKGROUND A noninvasive method to monitor changes in intracranial pressure (ICP) is required for astronauts on long-duration spaceflight who are at risk of developing the Visual Impairment/Intracranial Pressure syndrome that has some, but not all of the features of idiopathic intracranial hypertension. We assessed the validity of distortion product otoacoustic emissions (DPOAEs) to detect chan...

Raised intracranial pressure (ICP) is associated with poor outcome after brain injury, but is difficult to detect without invasive devices. As a part of the central nervous system, the optic nerve is surrounded by a dural sheath, and the subarachnoid space surrounding the optic nerve is subject to the same pressure changes as the intracranial compartment. Distension of the optic nerve sheath re...

Pneumoperitoneum during laparoscopy has been known to result in a rise in intracranial pressure (ICP) in experimental studies. There are no reports of the effect of pneumoperitoneum during diagnostic laparoscopy in patients suffering closed head injuries. We present the case of a 39 year old male with a closed head injury. Diagnostic laparoscopy was performed while intracranial pressure was mon...
