【摘要】 目的　 探讨气道闭合压 (P0 1 )在小儿机械通气中的临床价值。 方法 　对收住儿童ICU的呼吸衰竭上呼吸机的患儿 ,分别于上呼吸机第一天和撤机时 (中枢性呼吸衰竭放弃治疗的那一天 )测气道闭合压 (P0 1 )。 结果 　在外周型呼吸衰竭患儿 ,0～ 1岁组、1～ 3岁组和 3岁以上组 ,P0 1 在撤机时与上呼吸机第一天比较均有显著的统计学差异 (P <0 0 0 1或 0 0 0 1<P <0 0 5 )。 结论 　在机械通气中 ,检测P0 1 的动态变化 ,可了解患儿的病情变化 ,指导呼吸机参数的调节 ,为临床小儿呼吸机的成功撤离提供了有关肺功能的预测指标。更多还原

【Abstract】 Objective To assess airway pressure 0\^1 s (P\-\{0\^1\}) of pediatric patients with mechanical ventilation.Methods P\-\{0\^1\} were monitored when patients were mechanically ventilated on the first day and the day weaning from respirator.Results P\-\{0\^1\} obtained on the first day compared to those in the day weaning from respirator,there was significant difference between 0～1 years old group,1～3 years old group and 3～16 years old group (P<0\^001 or 0.001<P<0\^05).There was not significant difference among different time periods in central respiratory failure group when P\-\{0\^1\} compared to those among different time groups.Conclusion The parameter of respirator can be adjusted more correctly in mechanical ventilation through monitoring the change of P\-\{0\^1\}. and it can predict weaning criteria from ventilator.更多还原
