Change over time in ventilatory parameters during the first week after onset of ARDS. a Driving pressure (= plateau pressure – PEEP), b plateau pressure, c PEEP, d compliance (= tidal volume / (plateau pressure – PEEP)), e respiratory rate, f tidal volume/kg predicted body weight. Error bars show 95% confidence intervals. *Differences between university and non-university hospitals during the day after onset of ARDS (mean ± SD): driving pressure, 14.9 ± 5.6 vs 17.3 ± 5.5 cmH2O, p = 0.007; PEEP, 10.2 ± 5.1 vs 8.0 ± 4.1 cmH2O, p = 0.002; compliance, 47.9 ± 28.0 vs 36.8 ± 19.9 ml/cmH2O, p = 0.006. PEEP also differed between university and non-university hospitals during the second day after the onset of ARDS: 10.3 ± 4.9 vs 8.4 ± 4.0 cmH2O, p = 0.004. PEEP positive end-expiratory pressure
