Table 3 Area under the receiver operator characteristic curves and standard error for each index in the prospective-validation data set

From: A new integrative weaning index of discontinuation from mechanical ventilation

Index Area + SE
Cst,rs 0.83 ± 0.04
IWI 0.96 ± 0.02
P 0.1 0.72 ± 0.05
f 0.73 ± 0.05
Vt 0.81 + 0.05
f/Vt × P 0.1 0.80 + 0.05
f/Vt 0.85 + 0.04
PaO 2 /FiO 2 0.65 ± 0.06
  1. f = respiratory rate; f/Vt ratio = frequency to tidal volume ratio; IWI = integrative weaning index; P 0.1 = airway occlusion pressure; PaO2/FiO2 ratio = ratio of arterial oxygen tension to fraction of inspired oxygen; SE = standard error; Vt = tidal volume.
