A low Hb of 7 g/dl shows that 98% is not a reliable parameter: 7 g (Hb) x 0.98 (%) x 1.34 (OCC) = 9.2 ml O 2 /dl. " - How hemoglobin can bind to oxygen

How hemoglobin can bind to oxygen

WebThe oxyhemoglobin dissociation curve reflects the relationship between the oxygen saturation of hemoglobin and the partial pressure of arterial oxygen. It can shift depending on various factors, but if we look at the reasons behind how the body delivers oxygen to the tissues, we can discern the different triggers. WebScore: 4.7/5 (18 votes) . Carbon monoxide is dangerous for several reasons. When CO binds to one of the binding sites on hemoglobin, the increased affinity of the other binding sites for oxygen leads to a left shift of the oxygen dissociation curve and interferes with unloading of oxygen in the tissues.
