why do you get polycythemia in caroxyheamoglobin toxicity
the dissociation curve to the left
impairing the ability of heme to load O2 at the tissue level – TISSUE HYPOXIA
Kidney - makes more EPO - stimulated BM to make more RBC –> secondary POLYCYTHEMIA
why do you have normal saturations in carboxyhemoglobin
b/c the oximetry cannot does not differentiate b/w carboxyhemoglobin and oxyhemoglobin
Therefore must do ABG for Dx
