Non-Invasive Intracranial Pressure Measurement

An acknowledged objective of critical-care medicine is a timely, accurate, readily deployable, cost-effective, and, importantly, safe means of assessing and/or monitoring critical aspects/parameters of patient condition such as intracranial pressure (ICP). However, ICP monitoring is complicated by a large set of variables related to the patients themselves — presented symptoms, circumstances, and related information indicating such measurement, and relevant accompanying issues. These conditions and the various combinations thereof present attending physicians with the choice of many alternatives regarding key parameters including, but not limited to urgency, availability, appropriability, and accuracy to a minimum standard. Cost, complexity, ease-of-use, and other issues are also meaningful factors, but the bottom line for any of the various technical approaches, whether invasive or noninvasive, is performance. Key to this technology is its capability to correlate closely with established tympanic membrane displacement (TMD) ICP monitoring technology.
