Cerebral blood flow is highly sensitive to alterations in the partial pressures of O(2) and CO(2) (P(O(2)) and P(CO(2)), respectively) in the arterial blood. In humans, the extent to which nitric oxide (NO) is involved in this regulation is unclear.

Breath-by-breath variability of the end-tidal partial pressure of CO2 (Pet(CO2)) has been shown to be associated with cerebral blood flow (CBF) fluctuations. These fluctuations can impact neuroimaging techniques that depend on cerebrovascular blood f

Central command and the exercise pressor reflex can independently reset the carotid baroreflex (CBR) during exercise. The present investigation assessed the interactive relationship between these two neural mechanisms in mediating baroreflex resettin

The aim of this study was to elucidate (1) the cardiovascular responses to acute isocapnic hypoxia stimuli following five nights of normobaric poikilocapnic hypoxia, and (2) whether the changes in the cardiovascular responses to hypoxia are correlate

The relative importance of CO2 and sympathetic stimulation in the regulation of cerebral and peripheral vasculatures has not been previously studied in humans. We investigated the effect of sympathetic activation, produced by isometric handgrip (HG)

This study describes a protocol to determine acute cerebrovascular and ventilatory (AHVR) responses to hypoxia. Thirteen subjects undertook a protocol twice, 5 days apart. The protocol started with 8 min of eucapnic euoxia (end-tidal P(CO2) (PET(CO2)

The effects of discontinuous hypoxia on cerebrovascular regulation in humans are unknown. We hypothesized that five nocturnal hypoxic exposures (8 h/day) at a simulated altitude of 4,300 m (inspired O2 fraction = ∼13.8%) would elicit cerebrovascula

This study examined the effects of five nights of normobaric hypoxia on ventilatory responses to acute isocapnic hypoxia (AHVR) and hyperoxic hypercapnia (AHCVR). Twelve male subjects (26.6 +/- 4.1 years, standard deviation (S.D.)) slept 8-9 h per da

During exercise, the carotid baroreflex is reset to operate around the higher arterial pressures evoked by physical exertion. The purpose of this investigation was to evaluate the contribution of somatosensory input from the exercise pressor reflex t

Lifting of a heavy weight may lead to “blackout” and occasionally also to cerebral hemorrhage, indicating pronounced consequences for the blood flow through the brain. We hypothesized that especially strenuous respiratory straining (a Valsalva-li
