Herein, we review mechanisms regulating cerebral blood flow (CBF), with specific focus on
humans. We revisit important concepts from the older literature and describe the interaction …

Sleep-induced apnea and disordered breathing refers to intermittent, cyclical cessations or
reductions of airflow, with or without obstructions of the upper airway (OSA). In the presence …

Key points• The partial pressures of arterial carbon dioxide () and oxygen () has a marked
influence on brain blood flow.• It is unclear if the larger brain arteries are also sensitive to …

Cerebral blood flow (CBF) and its distribution are highly sensitive to changes in the partial
pressure of arterial CO2 (PaCO2). This physiological response, termed cerebrovascular …

Introduction Postoperative delirium is common in older patients. Despite its prognostic
significance, the pathophysiology is incompletely understood. Although many risk factors …

Intact, coordinated, and precisely regulated cerebrovascular responses are required for the
maintenance of cerebral metabolic homeostasis, adequate perfusion, oxygen delivery, and …

Obstructive sleep apnea (OSA) is defined by interrupted breathing during sleep due to
airway obstruction with an ongoing respiratory effort. In adults, OSA most commonly is …

In contrast to the cerebroarterial system, the cerebrovenous system is not well examined and
only partly understood. The cerebrovenous system represents a complex three-dimensional …

Sleep unmasks a highly sensitive hypocapnia‐induced apnoeic threshold, whereby apnoea
is initiated by small transient reductions in arterial CO2 pressure (PaCO2) below eupnoea …
