values at different study times. Individual partial pressure of arterial oxygen (PaO2) at inclusion, immediately after intubation (TI), 5 minutes after intubation, and 30 minutes after intubation of patients in the control group (top), and RM group (bottom). A full circle represents an individual value. Bars represent median values. One patient had a PaO2 of 504 mmHg after RM. These data are not shown in the Figure.
