Cerebrovascular reactivity is the change in cerebral blood flow in response to a vasodilatory
or vasoconstrictive stimulus. Measuring variations of cerebrovascular reactivity between …

Quantitative measurements of brain perfusion are influenced by perfusion-modifiers.
Standardization of measurement conditions and correction for important modifiers is …

The cardiovascular system is essential for life and has been a central focus of
psychophysiological investigation for several reasons. First, at least some its parameters …

Cerebrovascular reactivity (CVR) is the change in cerebral blood flow (CBF) in response to a
change in a vasoactive stimulus. Paradoxical reductions in CBF in response to vasodilatory …

Purpose To evaluate the safety, tolerability, and technical feasibility of map**
cerebrovascular reactivity (CVR) in a clinical population by using a precise prospectively …

We sought to characterize and quantify the performance of a portable dynamic end-tidal
forcing (DEF) system in controlling the partial pressure of arterial CO2 (PaCO2) and O2 …

Aging is associated with decreased vascular compliance and diminished neurovascular-and
hypercapnia-evoked cerebral blood flow (CBF) responses. However, the interplay between …

Carbon dioxide (CO 2) is an end product of aerobic cellular respiration. In healthy persons,
PaCO 2 is maintained by physiologic mechanisms within a narrow range (35–45 mm Hg) …

Acute hypoxia increases pulmonary arterial (PA) pressures, though its effect on right
ventricular (RV) function is controversial. The objective of this study was to characterize …

Background In video-assisted thoracoscopic surgery (VATS), intubated anesthesia may
affect cerebral oxygen balance and postoperative cognitive dysfunction (POCD). To avoid …
