Oxygen extraction kinetics

Older-adults decrease oxygen extraction kinetics in humans (0.09 vs. 0.15 %s-1).

“When compared with the young, older adults showed reduced oxygen extraction kinetics (OE, 0.15 [0.12-0.17] vs. 0.09 [0.05-0.12]%s−1) and magnitude (So2deficit, 3,810 ± 1,420 vs. 2,723 ± 1,240%s) during ischemia”
