Arm && Interventions

Group	Intervention	Description
observation	Position, waveform	this study measure the cuff leak volume and cuff leak ratio according to the cuff leak test with different positions and waveform,, at the same time observe the patient general condition, vital signs, oxygen saturation, cuff leak test results under different conditions and the breathing machine parameters, the diameter of the airway, the use of sedatives and hormones, after extubation stridor and intubation is happening again, the use of NPPV after extubation, patient outcomes

Primary Outcome Measures

Name	Time	Method
post-extubation stridor	48 hours	Inspiratory stridor within 48 hours of extubation and was usually associated with respiratory distress

Secondary Outcome Measures

Name	Time	Method
Extubation failure due to PES	48 hours	the need for reintubation in the 48 hours following extubation in a patient with post-extubation stridor.
