Near-infrared (IR) light easily penetrates biological tissue, and the information offered by in
vivo spectroscopy of cerebral oxygenation is detailed and comes with a high temporal …

Near-infrared spectroscopy (NIRS) is used to monitor regional cerebral oxygenation (rScO2)
during cardiac surgery but is less established during non-cardiac surgery. This systematic …

Cerebral autoregulation (CA) is a critical process for the maintenance of cerebral blood flow
and oxygenation. Assessment of CA is frequently used for experimental research and in the …

Background This study compares the accuracy of cerebral monitoring systems in detecting
cerebral ischemia during carotid endarterectomy. Methods The authors compared …

Objectives: Cognitive deficits occur in up to 80% of patients after cardiac surgery. We
investigated the influence of cerebral perfusion and embolization during cardiopulmonary …

BACKGROUND.: Near-infrared spectroscopy is a potential tool for measuring adequacy of
cerebral oxygenation during cardiac operations. The cerebral microcirculation is …

Background and Purpose—To date, the clinical application of near infrared spectroscopy in
the adult brain has been limited. The NIRO 300 (Hamamatsu Photonics) provides a …

We examined the relationship between changes in cardiorespiratory and cerebrovascular
function in 14 healthy volunteers with and without hypoxia [arterial O2 saturation (SaO2)∼ …

Cerebral blood flow (CBF) is regulated to secure brain O2 delivery while simultaneously
avoiding hyperperfusion; however, both requisites may conflict during sprint exercise. To …

The influence of severe passive heat stress and hypohydration (Hypo) on cardiorespiratory
and cerebrovascular function is not known. We hypothesized that 1) heating-induced …
