  • Model 1 no adjusted.

  • Model 2 adjusted for age, gender, medication history, smoking, BMI, CCI, APACHE II score, tracheal tube size, septic shock, OI, duration of intubation, the model is not adjusted for the variable itself.

  • Model 3 adjusted for age, gender, BMI, CCI, APACHE II score, tracheal tube size, septic shock, OI, duration of intubation, total norepinephrine, total epinephrine, the model is not adjusted for the variable itself.

  • APACHE, Acute Physiology and Chronic Health Evaluation; BMI, body mass index; CCI, Charlson Comorbidity Index; OI, oxygenation index.
