Data in bold are prescribed settings. Other data are measured parameters that depend on the ventilatory settings and the respiratory status of the child.
* Data expressed in parentheses represent measurements that were very variable over time, and hence an estimate of the measured parameter is provided [See Figure 4].
Abbreviations: SIMV, synchronized intermittent mandatory ventilation; NAVA, neurally adjusted ventilatory assist; PEEP, positive end-expiratory pressure; FiO₂, fraction of inspired oxygen; Edi, electrical activity of the diaphragm
