PaO2/FiO2 (a), PaCO2 (b) and respiratory rate (c) in the four study steps. Results are displayed as median, interquartile range, maximum and minimum. With HFOTTRACHEAL device, PaO2/FiO2 increases proportionally to gas flow, especially between 10 and 30 L/min. As compared to standard oxygen, 50 L/min, but not 30 L/min nor 10 L/min, ameliorate oxygenation and reduce respiratory rate in isocapnic conditions
