Hypoxemia can occur when the lungs are not functioning properly or when the heart is unable to pump enough blood to the lungs for oxygenation. Hypoxemia can lead to hypoxia, a deficiency in the amount of oxygen delivered to the organs and tissues of the body.
Symptoms of hypoxia can include shortness of breath, elevated blood pressure, a rapid heart rate, lightheadedness or stupor and cyanosis, a bluish color to the skin.
