九二氧化碳结合力测定二氧化碳在血液中的运输存在著两种方式,一是物理性的溶解;另一是与血液中其他物质呈可逆性的化学结合。以物理性溶解在血液中的二氧化碳视少,在100毫升血浆中尚不到3毫升,仅占二氧化碳总量的百分之几,而90％以上的二氧化碳系与血液中硷性金属离子结合成为重碳酸盐形式存在(在血浆中多为碳酸钠NaHCO_3,在血球中则多为碳酸钾KHCO_3),此外尚有少部份二氧化碳与血液中蛋白质及血红蛋白结合成氨基甲酸化合物。二氧化碳结合力或二氧化碳容量系指在标准状况时(摄氏0℃,760毫米水银柱压力)每100毫升血浆以重
Carbon dioxide binding determination of carbon dioxide in the blood transport there are two ways, first, the physical dissolution; the other with the blood of other substances was reversible chemical combination. Physically dissolved in the blood as less carbon dioxide, less than 3 ml in 100 ml of plasma, accounting for only a few percent of the total amount of carbon dioxide, and more than 90% of the carbon dioxide and blood alkaline metal ions become In the form of bicarbonate (sodium bicarbonate is mostly sodium carbonate in blood plasma and KHCO 3 is the most abundant in blood cells), a small amount of carbon dioxide is combined with blood proteins and hemoglobin to form carbamic acid compounds. Carbon dioxide binding or carbon dioxide capacity refers to the weight of carbon dioxide per 100 milliliters of plasma under standard conditions (0 ° Celsius at 760 mmHg)
