Hypokalemia plus elevated carbon dioxide (CO2) content usually indicates renal or gastrointestinal potassium (K+) loss. Hypokalemia plus decreased CO2 content usually means intestinal K+ loss. Hyperkalemia is common in metabolic acidosis and oliguric renal failure. With hemolysis or thrombocytosis, serum K+ concentration may be elevated while plasma concentration is normal. A CO2 value less than 18 mmole/liter suggests metabolic acidosis; a value greater than 30 mmole/liter suggests metabolic alkalosis.
低钾血症伴二氧化碳（CO2）含量升高通常提示肾脏或胃肠道钾（K+）丢失。低钾血症伴二氧化碳含量降低通常意味着肠道K+丢失。高钾血症在代谢性酸中毒和少尿性肾衰竭中很常见。发生溶血或血小板增多症时，血清K+浓度可能升高而血浆浓度正常。二氧化碳值低于18毫摩尔/升提示代谢性酸中毒；值高于30毫摩尔/升提示代谢性碱中毒。
