Understanding the contribution of the autonomic nervous system to cerebral blood flow
(CBF) control is challenging, and interpretations are unclear. The identification of calcium …

To ensure neuronal survival after severe traumatic brain injury, oxygen supply is essential.
Cerebral tissue oxygenation represents the balance between oxygen supply and …

In this Outlook paper, we explain why an accurate physiological interpretation of functional
near-infrared spectroscopy (fNIRS) neuroimaging signals is facilitated when systemic …

Background A previous retrospective single-centre study suggested that the percentage of
time spent with cerebral perfusion pressure (CPP) below the individual lower limit of …

Purpose Patients with dysautonomia often experience symptoms such as dizziness,
syncope, blurred vision and brain fog. Dynamic cerebral autoregulation, or the ability of the …

The cerebral oxygen cascade includes three key stages:(a) convective oxygen delivery
representing the bulk flow of oxygen to the cerebral vascular bed;(b) diffusion of oxygen from …

Abstract Purpose CPPopt denotes a Cerebral Perfusion Pressure (CPP) value at which the
Pressure-Reactivity index, reflecting the global state of Cerebral Autoregulation, is best …

Cerebral hemodynamics, eg, cerebral blood flow, can be measured and quantified using
many different methods, with transcranial Doppler ultrasound (TCD) being one of the most …

Over a wide range of systemic arterial pressures, cerebral blood flow (CBF) is regulated
fairly constantly by the cerebral vessels in a process termed cerebral autoregulation (CA) …

Given the complexity of cerebral pathology in patients with acute brain injury, various
neuromonitoring strategies have been developed to better appreciate physiologic …
