Background Cerebrovascular reactivity (CVR), an important measure of cerebrovascular
health in adults, has not been examined in healthy adolescents. Beyond the direct …

BACKGROUND In vitro experiments are critical for understanding the impact of medical
devices and techniques on blood vessels and blood flow. However, their interpretation is …

The cerebrovasculature responds to blood gas challenges. Regional differences (anterior
vs. posterior) in cerebrovascular responses to increases in CO 2 have been extensively …

Pilots in modern tactical aircraft breathe oxygen-enriched gas supplied by onboard oxygen
generating systems OBOGS. These may provide their maximum possible oxygen fraction at …

Cerebral autoregulation (CA) is impaired during acute high-altitude (HA) exposure,
however, effects of temporarily living high and working higher on CA require further …

Objective We aim to investigate the role of sea-level cerebral blood flow (CBF) in the
prediction of acute mountain sickness (AMS) by using three-dimensional pseudo-continuous …

Hypoxia has a detrimental impact on the brain due to its large oxygen demand. Hypoxia
induced deficits are of concern for pilots, who undertake training to recognize their own …

The blood flow in the cerebrum of humans is essential for survival. Regulation of cerebral
blood flow is vital because it allows the brain to get its nutrients and oxygen even when the …

Aim The coronavirus disease-19 has caused the death of more than five million people and
the treatment of millions in intensive care units since 2019. In this process, the possibility of …
