Hypoxemia that does not respond well to oxygen therapy is typically caused by a shunt. A shunt refers to blood that is not able to be oxygenated because it is bypassing normal lung tissue and flowing directly into the systemic circulation. Despite oxygen therapy, this blood will not become oxygenated and the patient will continue to experience hypoxemia.
