observation

Description:

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

Treatment:

Behavioral: Position, waveform
