The inadequate supply of oxygen to the body as a whole.


A decrease in oxygen saturation of the blood caused by sleep apnea, inadequate pulmonary ventilation, and shunts in the pulmonary circulation are examples of the causes of generalized hypoxia. Low partial pressure of atmospheric oxygen such as found at high altitude also causes generalized hypoxia.
