Hypoxemia, or reduced oxygen in the blood, can be caused by:

  1. Low partial pressure of atmospheric oxygen (e.g., high altitudes)
  2. Inadequate pulmonary ventilation (e.g., chronic obstructive pulmonary disease)
  3. Carbon monoxide poisoning
  4. Reduced hemoglobin content in erythrocytes
  5. Decreased hematocrit
