hospital mortality was 10.4% vs 14.9% (difference， and Participants Randomized clinical trial conducted from January 2016 to April 2017 among 1153 adults deemed ready for weaning after at least 24 hours of mechanical ventilation at 18 intensive care units in Spain. Follow-up ended in July 2017. Interventions Patients were randomized to undergo a 2-hour T-piece SBT (n=578) or a 30-minute SBT with 8-cm H2O pressure support ventilation (n=557). Main Outcome and Measures The primary outcome was successful extubation (remaining free of mechanical ventilation 72 hours after first SBT). Secondary outcomes were reintubation among patients extubated after SBT; intensive care unit and hospital lengths of stay; and hospital and 90-day mortality. Results Among 1153 patients who were randomized (mean age，但SBT的模式和持续时间仍存在争议。
