Similarly, the measurement of respiratory mechanics parameters is also one of the key parameters in intensive care, especially for intubated patients, where airway management is key to life support.

[0003] In the prior art, there are two situations for the measurement of respiratory mechanics parameters that respiratory airway management relies on.
