The objective of the study was to test the hypothesis that dynamic cerebral pressure-autoregulation is associated with the outcome of patients with severe head injury and to derive optimal criteria for future studies on the predictive value of autoregulation indices. Repeated measurements were performed on 32 patients with severe head injury. Arterial blood… (More)
BACKGROUND Surgeons are increasingly placed under pressure to accept publication of their results and to abide by recommendations to change practice which others derive. Considerable concern exists about misinterpretation of such data. The issue is well illustrated by this study. METHOD Data on outcome following treatment for subarachnoid haemorrhage were… (More)
The inclusion of the barometer sensor in smartphones signaled an opportunity for aiding indoor localization efforts. In this paper, we therefore investigate a possible use of the barometer sensor for detecting vertically oriented activities. We start by showing the accuracies of various commodity measurement devices and the challenges they bring forth. We… (More)
INTRODUCTION: Phase-contrast magnetic resonance imaging (PC-MRI) provides a unique method to accurately estimate velocities within a 3D region during the complete cardiac cycle. This 4D-flow technique enables studies of flow patterns in the heart and great vessels to provide new physiological insights [1,2]. Based on the acquired velocity data, particle… (More)
