WebOxygen delivery is proportional to the concentration of oxyhemoglobin (the hemoglobin level x oxygen saturation) and cardiac output. Peritubular interstitial cells in the kidney “sense” the tissue oxygenation level and control erythropoiesis in the bone marrow by producing erythropoietin (EPO) when more oxygenation is needed. Erythropoietin ... WebApr 7, 2024 · 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 indicate that your erythropoietin (EPO) may be low. Hemoglobin holds oxygen and RBCs hold …
