Predicting High Inspiratory Effort

Using occlusion pressure (Pocc)

Steps to using the calculator

1. Input the peak airway pressure from the ventilator during tidal breathing.
2. Input the PEEP setting.
3. Perform an expiratory hold, wait until the patient makes an inspiratory effort, then freeze the ventilator waveform (or record it if using a Servo i ventilator).
4. Using the ventilator cursor, measure the baseline and peak inspiratory (lowest drop in pressure) during the occlusion.
