The ventilatory response to carbon dioxide (CO2) measured by the steady-state method is
lower than that measured by Read's rebreathing method. A change in end-tidal PCO2 …

It is well established that the ventilatory response to carbon dioxide (CO2) measured by
modified rebreathing (SrVE) is closer to that measured by the steady-state method (SsVE) …

This study characterized cerebral blood flow (CBF) responses in the middle cerebral artery
to P CO2ranging from 30 to 60 mmHg (1 mmHg= 133.322 Pa) during hypoxia (50 mmHg) …

1. The ventilatory response to changes in end‐tidal carbon dioxide tension during
hyperoxia, obtained with Read's rebreathing method and a steady‐state technique, were …

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

We retrospectively examined arterial and endtidal estimations of CO2 tension used to
calculate cerebrovascular reactivity in 68 anesthetized patients. CBF was measured using …

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 …

Clinical transcranial Doppler assessment of cerebral vasomotor reactivity (CVMR) uses
linear regression of cerebral blood flow velocity (CBFV) vs. end-tidal CO2 (PetCO2) under …

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 …

Our aim was to quantify the end-tidal-to-arterial gas gradients for O2 (PET-PaO2) and CO2
(Pa-PETCO2) during a CO2 reactivity test to determine their influence on the …
