Abstract
Significant underestimation of blood electrolyte concentrations may occur if less than 1 ml of blood is withdrawn from an indwelling arterial line before taking the sample for analysis. Compared with arterial samples capillary samples give significant overestimations of potassium concentration and carbon dioxide tension, and significant underestimation of oxygen tension.
摘要
如果在从留置动脉导管采集血样进行分析之前抽取的血液少于1毫升，可能会出现血液电解质浓度的严重低估。与动脉血样相比，毛细血管血样会使钾浓度和二氧化碳分压显著高估，而氧分压显著低估。
