对56例呼吸衰竭患者进行氧动力学监测,显示氧输送量(DO_2)<450ml/(min·m~2)的22例,DO_2与氧耗量(VO_2)相关性好(r=0.6),滴注消心痛使 DO_2 上升。住院期间死亡6例,DO_2平均为282±40.65ml/(min·m~2),DO_2与VO_2呈线性相关(r=0.71)。以上结果提示氧动力学监测能较全面地判断机体缺氧,也是估价预后的一种手段。 Oxygen dynamics monitoring of 56 patients with respiratory failure showed that there were 22 cases of DO 2 <450ml / (min · m ~ 2), DO 2 had a good correlation with oxygen consumption (r = 0.6) Drip heartburn to DO_2 rise. There were 6 deaths during hospitalization, with an average of DO_2 of 282 ± 40.65ml / (min · m ~ 2). There was a linear correlation between DO_2 and VO_2 (r = 0.71). The above results suggest that oxygen kinetic monitoring can more completely determine the body hypoxia, but also a means of estimating the prognosis.
