Figure 2From: Replacement of anesthesia machines improves intraoperative ventilation parameters associated with the development of acute respiratory distress syndrome 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.Back to article page
