We observed a dramatic decrease in inspiratory pressure with a reduced requirement for oxygen (Figures 1  and 2 ). Within several minutes, the child's breathing became much more harmonious and smoother, while her respiratory parameters showed large variations from one cycle to another. SpO 2 was96%, mean airway pressure was 6 cm H 2 O, peak inspiratory pressure was 10 cm H 2 O, and minute volume was 0.6 l/min. Twelve hours later, FiO 2 was decreased to 21% with a mean airway pressure of 6 cm H 2 O. Detailed ventilatory parameters are reported in Table 1 . Since respiratory parameters were very low (Peak inspiratory pressure < 12 cm H 2 O with FiO2 < 25%) and blood gas values was normal, we extubated the child (10:30). She needed nasal continuous positive airway pressure for 3 days after which she was able to leave intensive care. Tracheal aspirate was positive for RSV and Streptococcus pneumoniae.
