A Daily fluid balances from day 1 to day 7 after Pediatric Intensive Care Unit admission showed to change significantly (p = 0.0014). At post hoc analysis, they showed significant differences between day 1 and days 2, 3, 4, and 5 respectively. B Daily fluid balances compared between different ventilatory modes: days spent with high flow nasal cannula (HFNC) and with non-invasive ventilation (NIV) including face mask and helmet, appeared to have significantly higher fluid balances with respect to those with mechanical ventilation (MV). Data are expressed as median and interquartile range. *Represents p < 0.01 and ** represents p < 0.001
