Ischemic hypoxia occurs when there is a reduced blood flow to the tissues and organs, particularly the brain, which leads to a deficiency in the amount of oxygen delivered to the cells. This can be caused by a variety of factors, including: 1. Vascular diseases: Conditions like atherosclerosis, which narrows the arteries, can reduce blood flow. 2. Heart conditions: Problems with the heart's ability to pump effectively, such as congestive heart failure or certain arrhythmias, can lead to ischemic hypoxia. 3. Blood clots: Thrombi can block blood vessels, cutting off the supply of oxygen-rich blood. 4. Shock: Severe blood loss or other forms of shock can reduce the overall blood flow in the body. 5. Anemia: While anemia is more commonly associated with hypoxic hypoxia due to a reduced number of red blood cells or their ability to carry oxygen, it can also contribute to ischemic hypoxia if the blood's oxygen-carrying capacity is significantly diminished. read more >>

Hypemic hypoxia �C Reduced brain function is caused by inadequate oxygen in the blood despite adequate environmental oxygen. Anemia and carbon monoxide poisoning are common causes of hypemic hypoxia. Ischemic hypoxia ( or "stagnant hypoxia") �C Reduced brain oxygen is caused by inadequate blood flow to the brain.read more >>
