Lack of oxygen in the body causes hypoxia or cyanosis. Leukemia is the name given to blood and bone marrow cancers. Hypoxia is not a cause of cancer.
Cardiac arrest is the most common condition that causes cerebral hypoxia. When the heart stops pumping, oxygen-rich blood cannot be delivered to vital organs such as the brain. Hypoxia to the brain causes irreversible brain damage after two minutes.
Chronic microvascular ischemic changes are when there are tiny blood vessels in the brain that have ruptured or clotted. This causes very small strokes.

blood clot in the lung anemia
Transient ischemic attacks.
Hypoxia is where there is low oxygen concentrations in the tissures so therefore this must be due to the lack of oxygen in the blood due to poor/lack of gas exchange caused by the copd
Hypoxia can occur in healthy people when they ascend to high altitudes.
This deficiency is called hypoxia or hypoxemia.This deficiency is called hypoxia or hypoxemia.
1. too little oxygen in the inhaled air 2. inadequate ventilation (=the chest muscles and diaphragm moving air in and out of the lungs) 3. ventilation/perfusion (=blood flow) mismatch 4. Shunting (venous, unoxygenated blood flows through completely unventilated areas of the lung and mixes with oxygenated blood from functional areas of the lung going into the body - a severe form of no. 3, which doesn't improve much by giving oxygen) 5. inadequent diffusion of oxygen and carbon dioxide across the membrane between the air-filled alveoli and the blood (as in severe pneumonia or pulmonary edema) (6. "venous admixure effect" does not cause, but does worsen hypoxia - when the blood flowing into the lungs contains too much carbon dioxide (CO2) for the lungs to clear, as in acute heart failure or septic shock)
Oxygen relieves hypoxia.
Hypoxia can be treated with oxygen therapy
