Hypoxemia

 

a decrease in the oxygen content of the blood as a result of disruption of blood circulation, increased tissue requirements for oxygen (due to excessive muscular exertion, for example), decreased exchange of gases in the lungs when they are diseased, decreased hemoglobin content of the blood (for example, in anemias), and decreased partial pressure of oxygen in inhaled air (altitude sickness). The consequence of hypoxemia is hypoxia.
