The mean flow index—usually referred to as Mx—has been used for assessing dynamic
cerebral autoregulation (dCA) for almost 30 years. However, concerns have arisen …

Cerebral autoregulation is a complex mechanism that serves to keep cerebral blood flow
relatively constant within a wide range of cerebral perfusion pressures. The mean flow index …

Abstract Background Mean flow index (Mxa) for evaluating dynamic cerebral autoregulation
is derived using varying approaches for calculation, which may explain that the reliability …

Dynamic cerebral autoregulation is often assessed by continuously recorded arterial blood
pressure (ABP) and transcranial Doppler-derived mean cerebral blood flow velocity followed …

Cerebral autoregulation controls cerebral blood flow under changing cerebral perfusion
pressure. Standards for measurement and analysis of dynamic cerebral autoregulation …

Objective: Different methods to calculate dynamic cerebral autoregulation (dCA) parameters
are available. However, most of these methods demonstrate poor reproducibility that limit …

Cerebral autoregulation (CA) refers to the control of cerebral tissue blood flow (CBF) in
response to changes in perfusion pressure. Due to the challenges of measuring intracranial …

Parameters describing dynamic cerebral autoregulation (DCA) have limited reproducibility.
In an international, multi-center study, we evaluated the influence of multiple analytical …

Cerebral autoregulation is the intrinsic ability of the brain to maintain adequate cerebral
perfusion in the presence of blood pressure changes. A large number of methods to assess …

The transcranial Doppler ultrasound-derived mean flow index (Mxa) is widely used for
assessing dynamic cerebral autoregulation (dCA) in different clinical populations. This study …
