Evolution and respiratory assistance
The days of PICU admission were lower in the group with only-HFNC (p 0.025). The SatO2/ FiO2 was lower in the only-NIMV group and higher in the only-HFNC group (p 0.026). The PCO2 was more elevated in the NIMV-only group (p 0.032). Also, the median number of days with HFNC is lower in the only- HFNC group than in the one in which HFNC is combined with NIMV (2 days versus 3; Table 3). None of the patients who received HFNC initially required NIMV later. There were no intubations or deaths.
