Blackout can occur during ascent from a deep freedive or immediately after surfacing. This is due to a relatively rapidly lowered oxygen partial pressure caused by a reduction in ambient pressure after much of the available arterial oxygen has been used up at the higher partial pressures induced by depth, leaving the diver in a state of latent hypoxia, with actual cerebral hypoxia inevitable ...
