New Findings What is the central question of this study? There is an interaction between the
regulatory systems of respiration and cerebral blood flow, because the mediator (CO2) is the …

New Findings What is the central question of this study? Do differing magnitudes of
ventilation influence cerebrovascular CO2 reactivity and the cerebral blood flow response to …

Non‐technical summary Two mechanisms control brain blood flow by changing blood
vessel diameter: autoregulation maintains flow in the face of perfusion pressure changes …

New Findings What is the central question of this study? What are the dynamic
characteristics of cerebrovascular carbon dioxide reactivity and the central respiratory …

This study examined cerebrovascular reactivity and ventilation during step changes in CO2
in humans. We hypothesized that:(1) end‐tidal P (P) would overestimate arterial P (P) during …

New Findings What is the central question of this study? The relationship between changes
in cerebral blood flow and arterial carbon dioxide tension is used to assess cerebrovascular …

Stimulation of cerebral vasculature using hypercapnia has been widely used to study
cerebral vascular reactivity (CVR), which can be expressed as the quantitative change in …

New Findings What is the central question of this study? During a steady‐state
cerebrovascular CO2 reactivity test, do different data extraction time points change the …

The potential differences in cerebrovascular responses between the anterior and posterior
circulations to changes in CO 2 are unclear in humans. Using transcranial Doppler …

Cerebrovascular reactivity to changes in the partial pressure of arterial carbon dioxide (P)
via limiting changes in brain [H+] modulates ventilatory control. It remains unclear, however …
