Study Group:Research group: Suspend ventilator ventilation and switch to tracheal intubation for high flow oxygen supply. The flow rate is 40L/min, and FIO2 is the same as before. Continue to observe
Control group::The traditional SBT method was adopted: the mechanical ventilation mode was changed to the PSV mode, the PS level was set at 7cmH2O, PEEP<5cmH2O, FIO2 was subject to the same parameters
