Intrinsic Respiratory Rate Assessment During Mechanical Ventilation to Accelerate Spontaneous Breathing and Extubation

"The intervention is a simple brief test as follows: With the ventilator set with the patient clinical settings, it will be performed an up to 30sec-long or two inspiratory effort and-expiratory occlusion maneuver on the ventilator and/or switch the patient to pressure support for up to 30sec-long to assess the presence of intrinsic respiratory rate.~If an intrinsic respiratory rate ≥8 breaths per minute is present and P/F ratio is ≥150 it will be performed a 5-minute test in pressure support ventilation with the pressure support level to match the clinical setting of the patient. If the patient tolerates well 5 minutes in pressure support (see criteria below) the clinical team will be informed:~\- It will be indicated that the patient tolerated 5 min of PSV and suggest to the clinicians and physician in charge to transition the patient to pressure support ventilation plus suggest reducing sedation."
