8 Factors that May Lower Oxygen Levels + Tests - …

6/1/2020· Low iron or iron stores may also cause less oxygen utilization because oxygen binds to iron-containing molecules (heme) in hemoglobin. Low RBC and hemoglobin often reflect an iron deficiency. A low RBC or hemoglobin count may indie that your erythropoietin (EPO ) may be low.

Oxygen

Oxygen is often transported in bulk as a liquid in specially-insulated tankers because one liter of liquefied oxygen is equivalent to 840 liters of gaseous oxygen, at atmospheric pressure and 20 C. Such tankers are used to refill bulk liquid oxygen storage containers, which stand outside hospitals and other institutions with a need for large volumes of pure oxygen.
