WebMar 2, 2024 · Blood PO 2 measurements tend to be normal because PO 2 reflects O 2 dissolved in blood, and this process is not affected by CO. In contrast, hemoglobin-bound O 2 (which normally comprises 98 percent of arterial O 2 content) is profoundly reduced in the presence of carboxyhemoglobin (COHb). (See "Oxygen delivery and consumption" .)
