Correlation between the change in PO2/FIO2 ratio caused by a change of ventilatory strategy to the estimated change in positive end-expiratory pressure (PEEP) that accompanied that change. The changes were between high-flow nasal cannula (HFNC), non-invasive ventilation (NIV) and invasive mechanical ventilation (MV). The PEEP for HFNC was estimated at 3 cmH2O, while measured PEEP was used for NIV and MV. PEEP-values are jittered to avoid overlapping points in the graph. Pearson’s correlation was calculated using actual data
