Nonintrusive method of acquiring bedside intracranial and arterial pressure signals in trauma intensive care setting

Laboratory studies have shown that correlation analysis applied to the intracranial and arterial pressure signals provides a means for detecting loss of vascular tone during massive vasodilation induced by deep hypercapnia. In order to evaluate the clinical utility of this laboratory technique, clinical recordings of intracranial and arterial pressure were obtained by a nonintrusive digital recording system designed to be compatible with an activity intense, crowded, trauma intensive care setting.
