About Clearance and Approval


Definition and Causes

Anemia is a lack of blood, specifically red blood cells (RBCs). The deficiency of red blood cells and hemoglobin reduces the oxygen-carrying capacity of blood, causing pallor, fatigue, weakness, or shock.

Causes of anemia include excessive blood loss from internal bleeding or trauma, destruction of RBCs by disease, or abnormal production of RBCs in the bone marrow.

Evidence Index

FDA cleared, widely reimbursed
Strong body of evidence
Repeatedly favorable results
Early or mixed results
Unfavorable or no evidence
Strong evidence against HBOT

Treatment with Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy (HBOT) is an effective treatment for anemia. It is commonly used in cases of exceptional blood loss, where a blood transfusion is not possible or not wanted. HBOT pushes enough oxygen into blood plasma to reach vital organs and tissues.

[ 1 ] Note: The Undersea and Hyperbaric Medical Society (UHMS) approval for treatment of anemia extends only to severe anemia produced by blood loss. A qualified physician must make this assessment before hyperbaric oxygen is indicated for treatment of anemia. Other types of anemia are more appropriately treated in other ways.

Read the page Severe Anemia in the UHMS resource library for more information.
