WebOct 22, 2024 · The main types of hypoxia include: 2. Hypoxic hypoxia (hypoxemic hypoxia) : There is a lack of oxygen in the blood flowing to the tissues. Hypemic hypoxia : Blood isn't able to carry oxygen as well as it should. Often this is because of an insufficient amount of healthy red blood cells. This leads to a lower supply of oxygen in the tissues. WebAug 1, 2004 · Tissue hypoxia is a deficiency of oxygen at the tissue level; it may be caused by increased demand, decreased supply or abnormal cellular utilization. The main physiological responses to acute normovolaemic anaemia are increased cardiac output and increased oxygen extraction ratio.
