duration of mechanical ventilation, size of endotracheal
tube, and reason for mechanical ventilation was apparent
between the treatment groups. No significant difference
in respiratory measurements, hemodynamic
parameters, level of albumin in the blood, and level of
hemoglobin at the end of weaning readiness assessment
was indicated between the groups (Table 2). In the non-
SBT group, the level of PS was 11.6 (1.1) cm H2O at the
time of extubation. In the SBT group, the level of PS
was 12.1 (1.4) cm H2O before the patient entered the
SBT phase. The Figure presents the treatment course
and the outcomes.
