APRV in the Operating Room is it Practical?

Airway Pressure Release Ventilation in the Operating Room is it Practical?
This is a good question, for one anesthesia delivery systems do not have APRV as a mode of ventilation available, so an ICU ventilator will need to be transported with the patient to the operating room.
Other considerations include:
-General anesthesia

A Unique Way to Obtain the NIF

Using the trigger setting to quantify extubation readiness. Notice the measured PEEP value & set PEEP value, the patient is able to generate a NIF < -18 cmH2O.

There are multiple ways to obtain the Negative Inspiratory Force (NIF) NIP (negative inspiratory pressure), or MIP (maximal inspiratory pressure) measurement. The NIF “corresponds to the negative pressure generated by the inspiratory muscles during a maximal inspiratory effort, performed during temporary occlusion of the airway opening” [1]. This parameter is used to quantify that the respiratory drive is sufficient (paralytics, narcotics, sedation is worn off after general anesthesia) or that there is no respiratory muscle fatigue or exhaustion.
