呼吸机捆绑式治疗的探讨A Review of the Ventilator Bundle,来自美国的报道,Question,什么是捆绑?What is a Bundle?,ANSWER,BUNDLE:同时综合运用一组有效的治疗手段优于运用单一治疗手段.A group of interventions related to a disease process,that,when executed together,result in better outcomes than when implemented individually.,呼吸机捆绑Ventilator Bundle,运用一组干预手段综合提高机械通气患者的治疗效果A group of interventions.that result in better outcomes in patients receiving
