Hypoxia - StatPearls - NCBI Bookshelf
Hypoxia occurs when oxygen is insufficient at the tissue level to maintain adequate homeostasis, stemming from various causes such as hypoventilation.
Pathophysiology, mechanisms, and managements of tissue hypoxia
The different mechanisms of tissue hypoxia are circulatory, anaemic, and hypoxic, characterised by a diminished DO 2 but preserved capacity of increasing ERO 2.
