A dual-gas hypercapnia/hyperoxia paradigm as used in
quantitative physiological MRI was performed while
subjects were monitored with a NIRS cerebral oximeter, a
finger-clip pulseox, and respiratory gas analyser to
obtain arterial and tissue oxygen saturation levels.
Increases in arterial and venous saturations were found
by combining the group data that could not be measured
in individuals. This has implications for the use of the
Davis model in calibrated fMRI.
