“…The idea of ear-to-ear ultrasound waves is strongly related to a previously mentioned concept [ 128 ] and was introduced in 2016 [ 262 ]. Although a preliminary report [ 263 ] predicted promising results with ear pressure sensors (HS-1000, HeadSense Medical Ltd., Netanya, Israel), a prospective study demonstrated only a moderate correlation (r = 0.604) between the estimated and real ICP [ 264 ].…”

(1) Background: Intracranial pressure (ICP) monitoring plays a key role in the treatment of patients in intensive care units, as well as during long-term surgeries and interventions. The gold standard is invasive measurement and monitoring via ventricular drainage or a parenchymal probe. In recent decades, numerous methods for non-invasive measurement have been evaluated but none have become established in routine clinical practice. The aim of this study was to reflect on the current state of research and shed light on relevant techniques for future clinical application. (2) Methods: We performed a PubMed search for “non-invasive AND ICP AND (measurement OR monitoring)” and identified 306 results. On the basis of these search results, we conducted an in-depth source analysis to identify additional methods. Studies were analyzed for design, patient type (e.g., infants, adults, and shunt patients), statistical evaluation (correlation, accuracy, and reliability), number of included measurements, and statistical assessment of accuracy and reliability. (3) Results: MRI-ICP and two-depth Doppler showed the most potential (and were the most complex methods). Tympanic membrane temperature, diffuse correlation spectroscopy, natural resonance frequency, and retinal vein approaches were also promising. (4) Conclusions: To date, no convincing evidence supports the use of a particular method for non-invasive intracranial pressure measurement. However, many new approaches are under development.

“…5 TBIs can alter cerebral autoregulation as well as increasing intracranial pressure (ICP) and reducing cerebral perfusion pressure (CPP), thus potentially leading to brain hypoxia if not promptly treated. [6][7][8] Management of TBI patients aims at lowering mortality and improving neurological outcome by decreasing ICP (i.e., in-crease in CPP) and by increasing brain oxygenation. 9 These two variables (ICP and brain oxygenation) are considered to be the main biomarkers for guiding treatment of TBI patients and for monitoring disease severity.…”

“… 18 , 19 Other approaches include the HeadSense monitor that uses an acoustic method. 20 Both optical nerve ultra-sound and transcranial Doppler have been demonstrated to provide a reasonable correlation with invasive ICP levels, but require a skilled operator and are difficult to use continuously and cannot be positioned over multiple regions of the brain. 21 …”

Background Intracranial pressure (ICP) monitoring requires placing a hole in the skull through which an invasive pressure monitor is inserted into the brain. This approach has risks for the patient and is expensive. We have developed a non-invasive brain pulse monitor that uses red light to detect a photoplethysmographic (PPG) signal arising from the blood vessels on the brain’s cortical surface. The brain PPG and the invasive ICP waveform share morphological features which may allow measurement of the intracranial pressure. Methods We enrolled critically ill patients with an acute brain injury with invasive ICP monitoring to assess the new monitor. A total of 24 simultaneous invasive ICP and brain pulse monitor PPG measurements were undertaken in 12 patients over a range of ICP levels. Results The waveform morphologies were similar for the invasive ICP and brain pulse monitor PPG approach. Both methods demonstrated a progressive increase in the amplitude of P2 relative to P1 with increasing ICP levels. An automated algorithm was developed to assess the PPG morphological features in relation to the ICP level. A correlation was demonstrated between the brain pulse waveform morphology and ICP levels, R 2 =0.66, P < 0.001. Conclusion The brain pulse monitor’s PPG waveform demonstrated morphological features were similar to the invasive ICP waveform over a range of ICP levels, these features may provide a method to measure ICP levels.
