    2016-6-20 · Oxygen extraction ratio (O2ER) is a ratio of the body's oxygen consumption (VO2) compared to the systemic oxygen delivery (DO2, formula below). A normal O2ER is ~25%. If oxygen delivery decreases, the O2ER increases as tissues extract more of the delivered oxygen. O2ER is a nice way to describe the adequacy of systemic oxygen delivery.
