Box plots showing the median and interquartile range of patient–ventilator asynchronies and electrical activity of the diaphragm (EAdi). (A) Rates of the autotriggering, double triggering, ineffective effort, premature cycling, and late cycling showed as numbers per minutes. (B) Asynchrony index and the trigger error and cycle-off error showed as the occupation of neural inspiratory and expiratory time, respectively. (C) Peak and mean inspiratory EAdi showed as µV. NAVA, neurally adjusted ventilatory assist; PSV, pressure support ventilation; Ten, neural expiratory time; Tin, neural inspiratory time. *P < 0.05; **P < 0.01.
