Abstract
In this study we investigated the possibility of obtaining accurate values of arterial Po(2) from specimens of capillary blood stored in glass capillary tubes and measured in an oxygen microelectrode. It has been shown that Po(2) measurements made on the Radiometer oxygen microelectrode are as accurate as those made on the macroelectrode and that the storage of blood is as satisfactory in glass capillary tubes as in glass syringes. The important feature in obtaining accurate values for arterial Po(2) is the choice of the capillary bed and its method of preparation for sampling. If the ear lobe is massaged with thurfyl nicotinate (Trafuril) it is possible to obtain values of Po(2) from the capillary blood which are in close agreement with arterial Po(2) in normal, hyperoxic, and shocked vasoconstricted patients.
摘要
在本研究中，我们探讨了从储存在玻璃毛细管中并在氧微电极上测量的毛细血管血标本获取动脉血氧分压（Po₂）准确值的可能性。结果表明，用Radiometer氧微电极进行的Po₂测量与用宏电极进行的测量一样准确，并且血液储存在玻璃毛细管中和玻璃注射器中一样令人满意。获得动脉Po₂准确值的重要因素是毛细血管床的选择及其采样的制备方法。如果用烟浪丁（Trafuril）按摩耳垂，就有可能从毛细血管血中获得与正常、高氧和休克性血管收缩患者的动脉Po₂非常接近的值。
