A 2025 editorial in The Journal of Physiology raises a key issue in neurocritical care: the lack of a continuous, direct cerebral blood flow monitor. While several technologies are under development, transcranial Doppler offers a practical and established option for real-time cerebral flow assessment at...

A new method transforms transcranial Doppler (TCD) velocity signals into cerebral arterial blood volume (CaBV) waves, revealing how impaired intracranial compliance affects blood distribution within the brain. This approach, validated against invasive ICP measurements, offers a promising, non-invasive tool to better understand pressure dynamics and...
