Using an open-circuit, breath-to-breath method, we continuously measured [Formula see text]O2 and relevant parameters during 120-min UBTs via a T-tube in 49 tracheostomized patients with prolonged MV, and calculated mean values in the first and last 5-min periods. Forty-one (84%) patients successfully completed the UBTs. The median [Formula see text]O2 increased significantly (from 235.8 to 298.2 ml/min; P = 0.025) in the failure group, but there was no significant change in the success group (from 223.1 to 221.6 ml/min; P = 0.505). In multivariate logistic regression analysis, an increase in [Formula see text]O2 > 17% from the beginning period (odds ratio [OR] 0.084; 95% confidence interval [CI] 0.012-0.600; P = 0.014) and a peak inspiratory pressure greater than - 30 cmH2O (OR 11.083; 95% CI 1.117-109.944; P = 0.04) were significantly associated with the success of 120-min UBT. A refined prediction model combining heart rate, energy expenditure, end-tidal CO2 and oxygen equivalent showed a modest increase in the area under the receiver operating characteristic curve of 0.788 (P = 0.578) and lower Akaike information criterion score of 41.83 compared to the traditional prediction model including heart rate and respiratory rate for achieving 48 h of unassisted breathing. Our findings show the potential of monitoring [Formula see text]O2 in the final phase of weaning in tracheostomized patients with prolonged MV.Faba bean (Vicia faba L.) is an important protein-rich fodder crop, which is widely cultivated in temperate areas. However, antinutritional compounds such as condensed tannins, limit the use of this protein source in monogastric feed formulations. Previous studies demonstrated that two recessive and co
