血液中氧及二氧化碳的測定对肺疾患和呼吸生理的研究均有重要意义,但是由于机体代偿情况的不同和血紅蛋白氧离曲綫的形态氧、二氧化碳的含量和飽和度在应用上有一定限制,而氧和二氧化碳分压此較更能表达生理或病理情况,作者們介紹了血液氧和二氧化碳分压測定的方法,并在Riley氏方法基础上加以改进,改进的部分包括:(1)应用定量 Blood oxygen and carbon dioxide determination of lung disease and respiratory physiology research are of great significance, but due to different body compensations and hemoglobin oxygen curve form oxygen, carbon dioxide content and saturation in the application of certain restrictions, The oxygen and carbon dioxide partial pressure of the more able to express the physiological or pathological conditions, the authors introduced the blood oxygen and carbon dioxide partial pressure measurement method and improved on the basis of the Riley’s method, improvements include: (1) the use of quantitative
