Peak arteriovenous oxygen difference

Advanced entry age is associated with peak arteriovenous oxygen difference in humans.

“steeper declines in V̇o2peak and (A - V)O2diff,peak were observed with advanced entry age but not in COpeak.”

HumansFree of clinical cardiovascular disease; adjusted for baseline values and peak workloadAverage 12.6 yearsn = 99

Longitudinal decline in peak V̇o₂ with aging in a healthy population is associated with a reduction in peripheral oxygen utilization but not in cardiac output
