Stagnant anoxia refers to a condition where there is a lack of oxygen circulating in the blood, typically caused by a blockage in a blood vessel leading to a particular organ or tissue. Synonyms for stagnant anoxia include ischemia, hypoxia, and anoxic hypoxia. Ischemia is a term used to describe a condition where there isn't enough blood supply to the tissue, which leads to inadequate oxygenation. Hypoxia is a condition where there is an insufficient supply of oxygen to the tissues, which can lead to cell death. Anoxic hypoxia is a type of hypoxia that results from a complete lack of oxygen. Anoxic hypoxia can occur in cases of drowning, suffocation, or respiratory failure.
