Tolerance to central hypovolemia is highly variable, and accumulating evidence suggests
that protection of anterior cerebral blood flow (CBF) is not an underlying mechanism. We …

Background and purpose: In humans, activation of the diving reflex by a cold stimulus to the
face results in bradycardia, peripheral vasoconstriction and an increase in blood pressure …

Despite its low incidence, cardiac arrest after spinal anesthesia carries a high mortality.
Counterintuitively, young and healthy patients with low resting pulse are at increased risk …

Purpose Cerebral oxygenation as measured by near-infrared spectroscopy (NIRS) might be
useful to discriminate between physiological and pathological responses after standing up …

Abstract Editor's Perspective What We Already Know about This Topic Cardiac output is an
independent regulator of cerebral blood flow in healthy awake humans The relationship …

The dynamic response of cerebral autoregulation to spontaneous changes in arterial blood
pressure (ABP) is described by the relationship between cerebral blood flow velocity (CBFV) …

Background Changes in systemic and cerebral hemodynamics in preterm infants during
early transitional circulation are complex and may differ between infants with or without …

The effects of orthostatic stress, induced by lower body negative pressure (LBNP), on
cerebral hemodynamics were examined in a nonlinear context. Spontaneous fluctuations of …

The aim of this study was to determine whether lower body negative pressure (LBNP),
combined with noninvasive methods of assessing changes in systemic and cerebral …
