Zusammenfassung
Introduction: In a recently introduced mathematical model ICP was assessed non-invasively (nICP) by usage of arterial blood pressure (ABP) and cerebral blood flow velocity (FV) curves. Well defined haemodynamic parameters (TCD characteristics) derived from both signals, were taken to control a linear signal transformation of ABP into ICP. In the current work attempts were made to improve former results by application of advanced data analysis techniques. Methods: In 201 patients (3–78 years, mean: 37±19 years) with either severe traumatic brain injury (N=176) or stroke (N=25) signal data consisting of FV, ABP an…
