血气分析对及时发现和处理肺泡通气、血液氧合及酸硷失衡有重要意义。临床上一般采用微量血气分析仪,作酸硷度(pH)、二氧化碳分压(Pco_2)及氧分压(Po_2)三个基本参数的测定,然后据此再进行一系列有关血气及酸硷的其他指标的查图和计算。通过这些数据的分析,对临床提出诊断和处理意见。要正确解释pH、Pco_2和Po_2这些数据,需要对血标本的采取、肺泡通气、血液氧合和酸硷平衡的生理及 Blood gas analysis on the timely detection and treatment of alveolar ventilation, blood oxygenation and acid-base imbalance of great significance. Clinically, the general use of trace blood gas analyzer for the pH (pH), partial pressure of carbon dioxide (Pco_2) and partial pressure of oxygen (Po_2) three basic parameters of the determination, and then conduct a series of related blood gas and acid Other indicators of the chart and calculation. Through the analysis of these data, clinical diagnosis and treatment suggestions. To correctly interpret the data for pH, Pco_2 and Po_2, it is necessary to understand the physiology of blood samples taken, alveolar ventilation, blood oxygenation and pH balance
