Predictors of ventilator weaning
The parameters that were statistically significant in univariate
analysis, including age, IL-6, D-dimer, TnI, IVSd, and PASP were further
evaluated in logistic regression analysis to explore whether they were
related to ventilator weaning. The results showed that D-dimer and IVSd
may be statistically significant risk factors for the failure of
ventilator weaning. The OR of D-dimer was 0.81 (95% CI 0.69‒0.95) and
the OR of IVSd was 0.16 (95% CI 0.045‒0.59) (Table 2).
