Critical oxygen pressure
Description
The critical oxygen pressure, pc, is defined as the partial oxygen pressure, pO2, below which aerobic catabolism (respiration or oxygen consumption) declines significantly. If anaerobic catabolism is activated simultaneously to compensate for lower aerobic ATP generation, then the limiting oxygen pressure, pl, is equal to the pc. In many cases, however, the pl is substantially lower than the pc.
