Hypoxemic hypoxia: Occurs when there may be inadequate oxygen within the blood, and due to this fact not enough oxygen reaches the body's tissues and vital organs. Hypemic (anemic) hypoxia: Occurs when the blood doesn't carry adequate amounts of oxygen resulting from low red blood cells (anemia). In consequence, the body's tissues do not obtain enough oxygen to operate usually. Stagnant (circulatory) hypoxia: Occurs when poor blood circulation prevents satisfactory oxygen supply to the body's tissues.
