Hypoxemia is a low level of oxygen in the blood. It lowers the amount of oxygen that reaches organs like the heart, kidney, and brain. It can be mild or severe. When severe it can affect heart and brain function.
Hypoxemia may be caused by:
Problems getting oxygen into the lungs—such as with asthma
Trouble moving oxygen from the lungs to the blood—such as with lung damage or disease
