Hypoxia / hypoxemia is a condition in which there is an inadequate supply of oxygen in the blood. Hypoxia is caused by:

# A reduction in partial pressure of oxygen
# Inadequate oxygen transport
# The inability of the tissues to use oxygen

1)Hypoxic Hypoxia
Hypoxic Hypoxia is a reduction of oxygen entering the blood. This condition occurs when:

# There is a reduction in oxygen pressure in the lungs
# Reduced gas exchange area
# Lung disease

2) Hypemic Hypoxia
Hypemic hypoxia is a reduction in the capacity of the blood to carry oxygen. This condition is caused by:

# A reduction of hemoglobin in the blood

This may be caused by blood donation, hemorrhage, or anemia.

# A reduction in the number of red blood cells

This may be caused by drugs, chemicals, smoking, or carbon monoxide exposure.

3) Stagnant hypoxia is a deficiency in oxygen due to poor blood circulation.

This condition occurs when a person sits or hangs, or is exposed to cold temperatures for prolonged periods of time.

4) Histotoxic Hypoxia
Histotoxic hypoxia is an inability of the tissues to use oxygen. This condition occurs during carbon monoxide or cyanide poisoning, or from the use of certain narcotics, chewing tobacco, and alcohol
