Scatterplots of average ventilation parameters over 2 months before and 2 months after new machines are integrated into practice. Significant changes were seen in peak inspiratory pressure (PIP) and drive pressure (∆P). Vt = tidal Volume, PEEP = positive end expiratory pressure, RR = respiratory rate.
