Hypoxia Diffusion

Hypoxia of the diffusion type, or diffusing hypoxia (ancient Greek ὑπό “under, above” + ὀξῦς “sour”), as an exception - “staged” (cf. hypoxemia), a syndrome manifested by sharp metabolic and hemodynamic disorders with sufficient (relative in contrast to the resting stage) blood oxygen saturation. In children, it manifests itself in three stages: predominantly of a respiratory nature, that is, due to hyperventilation, cardiac weakness and relative insufficiency of coronary circulation [1], from the second stage it is replaced by a relative insufficiency of cerebral blood flow with disruption of brain function and, as a consequence, convulsions, and the cerebral stage, when swelling of the cerebral cortex, cardiovascular failure, coma, paresis, paralysis, generalized epileptic seizures (due to overstimulation of neurons) develops.

Hypoxic differential decompensation can develop in a reversible manner, most often developing from the cardiovascular system.
