本文通过108例次血气应用两种计算方法进行比较对照,各种指标:pH、HCO3~、PaCO:、AG的结果经统计学处理,并无显著差异(P)0.05)。本文讨沦了pH、PacO:、HcO3之间关系,以及两种公式来源和代表的不同概念,实践证明HCO3-=PaCO_2×0.6计算简单、省时,判断酸硷失衡较为准确,适合临床应用。但是无论采取何种计算方法都应结合实验室检查及临床动态观察进行综合分析。
In this paper, 108 cases of blood gas using two calculation methods for comparison and control, various indicators: pH, HCO3 ~, PaCO:, AG results by statistical analysis, no significant difference (P) 0.05). In this paper, we discuss the relationship between pH, PacO: and HcO3, as well as different concepts of two kinds of formula sources and representations. Practice has proved that HCO3- = PaCO2 × 0.6 is simple and time-saving, and it is more accurate to judge the acid-base imbalance and is suitable for clinical application. However, no matter what method of calculation should be combined with laboratory tests and clinical dynamic analysis of a comprehensive analysis.
