Estimates of breathing effort

The neuromechanical efficiency index (NME) quantifies the amount of pressure the respiratory muscles can generate, normalized to EAdi (in cmH2O/μV) [26]. Calculating NME during brief end-expiratory occlusions (NMEoccl) can allow a non-invasive estimate: in the absence of airflow, changes in Paw equals changes in Pmus. NMEoccl can thus simply be calculated at the bedside as Pawoccl/EAdioccl [26, 77] (Fig. 5b). Taking an average of three out of five measurements with lowest variability is recommended [77].

呼吸努力的估计值

神经机械效率指数（NME）量化了呼吸肌可以产生的压力，统一为EAdi（单位为cmH2O/ μV）。计算短暂呼气末阻塞期间的NME（NMEoccl）可以行无创性估计：在没有气流的情况下，Paw的变化等于Pmus的变化。因此，NMEoccl可以在床边简单地计算为Pawoccl/EAdioccl（图5b）。建议取五次测量中可变性最小的三次测量的平均值。

1.修饰three。则为：取五次测量中可变性最小的三次测量的平均值

2.修饰five。则为：取可变性最小的五次测量中的三次测量的平均值
