Arterial O2 content is reduced in one of the following ­
Arterial PO2/ Dissolved oxygen is normal in anemic hypoxia, but the arterial oxygen content is low. Whereas, in Hypoxic hypoxia, both are low. In case of stagnant hypoxia/ischemic hypoxia and histotoxic hypoxia, both are normal.
Stagnant hypoxia
Anemic hypoxia
Histotoxic hypoxia
Ischemic hypoxia
