In this article from Experimental Physiology, Olsen et al. discuss the challenges and limitations of evaluating dynamic cerebral autoregulation (dCA) using mean velocity index-based measures. They argue that methodological inconsistencies have compromised the validity and reproducibility of these measures and advocate for enhanced experimental standardization. The authors also highlight the need for ongoing analytical innovations to account for the non-linear nature of cerebral autoregulation and the variability of dCA over time. They suggest that advancements in transcranial Doppler ultrasound technology and software could improve the reliability of dCA metrics. Overall, this review emphasizes the importance of standardization and methodological improvements in the study of cerebral autoregulation. [Extracted from the article]
