WebNov 29, 2024 · The lowered pH then decreases hemoglobins affinity for oxygen, meaning hemoglobin lets go of oxygen more easily. As a result, more oxygen is released to the muscles and tissues that need it most. Conversely, decreases in carbon dioxide will increase hemoglobins affinity for oxygen, meaning hemoglobin is less likely to release oxygen. WebOxygen affinity is measured as the partial pressure of oxygen to saturate 50 per cent of hemoglobin (P 50). Normal P 50 of human hemoglobin in RBCs is about 27 mmHg ( Bunn and Forget, 1986).
