Does tissue oxygenation index measured using spatially resolved spectroscopy correlate with changes in cerebral blood flow in newborn lambs?
We conclude that overall TOI changes are concordant with CBF variations, when arterial oxygen saturation and cerebral oxygen consumption are constant. While TOI reflects CBF, it is more sensitive to variations of CBF of low frequency (<0.1 Hz) than to more rapid, higher frequency changes.
The present study suggests that rapid weight gain during early childhood was associated with being overweight in preadolescence, regardless of sex.
