Distinguish among anemic, ischemic (stagnant), histotoxic, and hypoxemic hypoxia
What will be an ideal response
Anemic hypoxia reflects poor oxygen delivery resulting from too few RBCs or RBCs that contain abnormal or too little Hb. Ischemic (stagnant) hypoxia results when blood circulation is impaired or blocked. Histotoxic hypoxia occurs when body cells are unable to use O2 even though adequate amounts are delivered. Hypoxemia hypoxia is indicated by reduced arterial PO2.
