level chosen arbitrarily和non-fatiguing？

Percentage of the maximum EAdi during a failed SBT 

In difficult-to-wean patients, Rozé et al. [69] set the NAVA level to obtain EAdi amplitudes corresponding to ~ 60% of the EAdi peak (level chosen arbitrarily) that was measured during a failed spontaneous breathing trial under PSV (PS 7 cmH2O, no PEEP); this level was referred to as EAdimaxSBT. This procedure was repeated daily, allowing a progressive reduction of the NAVA level until extubation. Setting the NAVA level using EAdimaxSBT, was reasoned to be a non-fatiguing and objective target more relevant than volumetric goals, but additional monitoring may be required in patients with excessive respiratory drive [70].

SBT失败时最大EAdi的百分比

对于脱机困难的患者，Rozé 等人设置以获得对应于PSV（PS 7cmH2o，无PEEP）时自主呼吸试验失败期间测量的EAdi峰值约60%的EAdi振幅（任意选择的水平）的NAVA水平；这个水平被称为EAdimaxSBT。这个过程每天重复，允许NAVA水平逐步下降，直到拔管。使用EAdimaxSBT设置NAVA水平被认为是非疲劳的客观目标，比容量目标更为相关，但是对于呼吸驱动过度的患者可能需要额外的监测。

level chosen arbitrarily和non-fatiguing，总觉得怪怪的
