High po2 on venous blood gas

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" .) WebAug 10, 2016 · An arterial blood gas (ABG) is a test that measures the oxygen tension (PaO 2 ), carbon dioxide tension (PaCO 2 ), acidity (pH), oxyhemoglobin saturation (SaO 2 ), and bicarbonate (HCO 3) concentration in arterial blood. Some blood gas analyzers also measure the methemoglobin, carboxyhemoglobin, and hemoglobin levels.
