“…Similarly, ICP may be transduced by a catheter placed into the lumbar subarachnoid space (lumbar drain). 4,5 Fiberoptic intraparenchymal catheters, placed through a bolt into brain tissue, also allow for continuous ICP monitoring. Catheters that transduce pressure may also be placed in the epidural, subdural, or subarachnoid space but are less frequently used.…”

In severely injured patients, the immediate goal of resuscitation is restoration and maintenance of adequate tissue metabolism by ensuring sufficient delivery of fuel, typically oxygen and glucose, to meet cellular metabolic demands. In neurocritical care, traditional goals of resuscitation-intracranial pressure (ICP), cerebral perfusion pressure (CPP), and the clinical examination-have been extrapolated from those of general critical care. These variables are analogous to central venous pressure, mean arterial pressure, and urine output and are similarly crude. These distant surrogates for cerebral perfusion do not account for dynamic changes in cerebral autoregulation, tissue metabolic rate, cellular fuel use, and microcirculatory dysfunction, all of which impact tissue metabolic health. Although standard, it seems intuitively obvious that a uniform approach of maintaining ICP Ͻ20 mm Hg and CPP Ͼ60 mm Hg is overly simplistic. This approach does not address either significant baseline differences in patient physiology nor the complex, dynamic, and variable pathophysiological changes that ensue after severe brain injury. A more tailored therapeutic strategy that responds to multiple simultaneously measured and more relevant physiological variables is logically appealing. Until recently, however, the requisite individual patient physiology was inaccessible at the bedside.The emergence of technology that allows for continuous real-time bedside monitoring of cerebral physiology marks a new era in neurocritical care. These monitors facilitate assessment of therapeutic efficacy and may provide more relevant physiological end points for resuscitation. Combining these monitors in a multimodal approach allows for the practice of goal-directed cerebral resuscitation that emphasizes the individual patient's unique neurological and systemic physiology.

“…Cerebral edema must be diagnosed and treated as it causes an increase in intracranial pressure (ICP) and damages the patient's health (3). There are invasive and noninvasive methods that can be used to determine the increase of ICP (4)(5)(6). The gold standard for diagnosing increased ICP is the use of intracranial devices.…”

Background/aim: We aimed to show the role of determination of optic nerve sheath diameter (ONSD) by bedside ultrasonography in an emergency department in the diagnosis of cerebrovascular disorders and its correlation with the clinical picture. Materials and methods:This prospective cross-sectional study included 55 patients with cerebrovascular disorders and 53 controls. Age, sex, ONSD, comorbid disease status, and multidetector computed tomography results of all subjects and application periods and National Institutes of Health Stroke Scale (NIHSS) scores of the patient group were evaluated. Results:The ONSD of the patient and control groups was determined as a median of 5.7 mm and 3.6 mm, respectively. The ONSD of the patient group was determined to be significantly higher than that of the control group (P < 0.05). A positive relationship was determined between NIHSS scores and ONSD values (P < 0.05). The specificity and sensitivity values were determined as 98.1% and 81.8%, respectively, for a cutoff value of 5 mm and as 100% and 72.7%, respectively, for a cutoff value of 6 mm. Conclusion:This study showed that bedside measurement of ONSD is an easy, cheap, and noninvasive method that can be used to support the diagnosis and evaluation of patients with acute stroke.

“…This pressure is called intracranial pressure (ICP) and is measured in the cerebrospinal fluid (CSF). An increase of the volume in the human cranium raises the intracranial pressure, which can subsequently damage human brain cells [2]. This condition is known as intracranial hypertension.…”

“…Other techniques bring other advantages as less invasiveness (doesn't need to reach the cerebrospinal fluid) but with a loss in precision [6]. One recent technique involving a small flexible tube that is inserted into the lumbar spine surpasses the disadvantage of drilling into the human skull and can reach the cerebrospinal fluid [2]. There are other techniques that measure the intracranial pressure in different locations and with different types of sensors.…”

Ambient Assisted Living (AAL) aims to provide support to healthcare professionals making use of sensing, and information and communication technologies. Brain related information is becoming more and more relevant for many pathologies, but access to long-term information from brain to feed such AAL technologies is still giving the first steps. One main issue when recording signal from the brain is the available room for sensing device placement. Since available room is limited, battery-less solutions are welcome. Also, AAL solutions to be developed should consider not only the sensing device, but also the entire supporting framework. This paper introduces a solution for long-term monitoring of intracranial pressure using a wireless microdevice and a wireless sensor network. This work introduces a solution to achieve an enough miniaturized pressure sensor, powered by a wireless link, and analyzes the suitability of a wireless sensor network to support the data dissemination.
