Analyses of a multi-centre database of 71 patients at risk of raised ICP showed that in head injured patients (n = 19) and tumour patients (n = 13) clear inverse relationships of ICP vs compliance exist. SAH patients (n = 5) appear to exhibit a biphasic relationship between ICP and compliance, however greater numbers of patients need to be recruited to this(More)
INTRODUCTION An open collaborative international network has been established which aims to improve inter-centre standards for collection of high-resolution, neurointensive care data on patients with traumatic brain injury. The group is also working towards the creation of an open access, detailed and validated database that will be useful for post-hoc(More)
BACKGROUND The BrainIT group works collaboratively on developing standards for collection and analyses of data from brain injured patients towards providing a more efficient infrastructure for assessing new health technology. MATERIALS AND METHODS Over a 2 year period, core dataset data (grouped by nine categories) were collected from 200 head-injured(More)
BACKGROUND Studies of therapeutic interventions and management strategies on head injured patients are difficult to undertake. BrainIT provides validated data for analysis available to centers that contribute data to allow post-hoc analysis and hypothesis testing. METHODS Both physiological and intensive care management data are collected. Patient(More)
BACKGROUND The BrainIT project was conceived in 1997 and has grown into an international collaboration with the purpose of gathering high time resolution data from head injured patients utilising standardised methodologies. MATERIALS AND METHODS From 1998, 22 participating neuroscience centres collected three main types of information: demographic,(More)
Deciding upon shunting in patients with hydrocephalus with possibly related symptomatology, is difficult. The Spiegelberg automated device allows continuous measurements of intracranial compliance. We aimed to evaluate the added information that this new technology can provide, in addition to standard continuous ICP monitoring. Thirty-three patients with(More)
Monitoring of street lights and controlling is of utmost importance in developing country like India to reduce the power consumption. This paper presents a street light control system which combines various technologies: a timer, Liquid Crystal Display (LCD), a statistics of traffic flow magnitude, a photosensitive detector (LDR), infrared photoelectric(More)
The goal of this study was to compare the Spiegelberg intraventricular intracranial pressure (ICP)/intracranial compliance monitoring device, which features an air-pouch balloon catheter, with existing gold-standard methods of measuring ICP and intracranial compliance. A Spiegelberg intraventricular catheter, a standard intraventricular catheter, and a(More)
The Spiegelberg Compliance Device (Spiegelberg KG, Hamburg, Germany) has been available for the automated measurement and calculation of minute by minute intracranial compliance. Widespread practical use has been somewhat limited by the instability of values: especially at low intracranial pressures. We looked at two aspects of a methodology in an attempt(More)
