This document discusses the challenges of monitoring intracranial pressure (ICP) in patients with traumatic brain injuries. Currently, the only reliable method for measuring ICP is through invasive procedures, which carry risks and complications. However, researchers have developed a wearable device called Brain4Care (B4C) that can interpret pressure oscillations in the cranial vault and provide noninvasive measurements of ICP. While the B4C device shows promise, it has limitations such as sensitivity to patient movements and operator dependence. Other noninvasive methods for assessing ICP, such as analyzing blood pressure waveforms and measuring the diameter of the optic nerve sheath, also have limitations and are not yet fully validated. Overall, noninvasive methods can help exclude patients who do not have high ICP and guide treatment decisions, but invasive monitoring remains necessary in some cases. [Extracted from the article]
