When your blood is not able to carry a sufficient
amount of oxygen to the cells in your body, a con-dition called
hypemic hypoxia occurs. This type of hypoxia is a result of
a deficiency in the blood, rather than a lack of inhaled oxygen,
and can be caused by a variety of factors. For example, if you
have anemia, or a reduced number of healthy functioning blood
cells for any reason, your blood has a decreased capacity for
carrying oxygen. In addition, any factor that interferes or
displaces oxygen that is attached to the blood’s hemoglobin
can cause hypemic hypoxia. The most common form of hypemic hypoxia
is carbon monoxide poi-soning, which is discussed later. Hypemic
hypoxia also can be caused by the loss of blood that occurs
during a blood donation. Your blood can take several weeks to
return to normal following a donation. Although the effects
of the blood loss are slight at ground level, there are risks
when fly-ing during this time.
