Arterial O2 content is reduced in one of the following ­: (A) Stagnant hypoxia, (B) Anemic hypoxia, (C) Histotoxic hypoxia, (D) Ischemic hypoxia
Answer is B. 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.
